What grit should I use to hone cylinders?

In the case of most automotive combustion cylinders, 120 grit works for older cast ring sets or where the cylinder has been re-bored and is a little rough. Hones with 180 to 240 grits are good choices for general deglazing where the cylinder is not going to be bored or honed.

Can you hone a cylinder without removing piston?

The hone will not generate enough crap to warrant “plugging” the bottom of the cylinder. You risk doing more damage by trying to put a piston down in the bottom of the cylinder than could ever be done by the grit from the hone. Cover the crank and clean the cylinder and bottom end of the block when you are done.

What to use for honing cylinders?

With the cylinders free of as much loose material and old engine oil as possible, wipe some honing oil, or 10W 30 engine oil around the cylinder walls. Squeeze the honing stones together with one hand, and remove the steel retainer from between the arms.

How much material can be removed by honing?

The amount of Material Removal when Honing(abrasive flow machining) can be controlled to remove as little as . 001” and will depend on target set by customer. The rougher the starting surface finish is, the more material removal will be needed to achieve the best finish possible.”

How long should it take to hone a cylinder?

You should only have to hone for about 10 to 15 seconds at a time until you can see consistent crosshatch marks. The ball hone will be a little bit more abrasive, which is why we don’t recommend using a ball hone on plated cylinders unless they are specified to be safe.

What size Flex Hone should I use?

Flex-Hones are made oversize so you need to choose the size based on the size of your cylinder. If your cylinder is a non-standard size select the next largest size. For example, for a cylinder that has been machined to 3-3/8”, choose a 3-1/2” hone.

How much does it cost to hone a cylinder?

The usual cost for the honing or boring of the mains is $180. Once the mains are align-bored or honed, the centerline of the crankshaft is established. Next, the block is decked.

What is a good substitute for honing oil?

Various types of vegetable oils, mineral oil, industrial cleaner, window cleaner, and the old reliable water. As long as the liquid is light and will not harden, it will serve as a good alternative for honing oil. While the term might seem off, honing oil isn’t actually always oil.

What kind of lubricant is required for honing?

For best results whenever you hone, Brush Research Manufacturing (BRM) recommends using Flex-Hone® oil.

What is honing oil made of?

Composition. The two most common classes of honing oil are petroleum based (typically mineral oils), and non-petroleum (typically water or vegetable oil) based. Common additives include chlorine, sulfur, rust inhibitors, and detergents.

How long should you hone a cylinder?

Do you have to hone cylinders when replacing rings?

More often than not, you will need to hone your cylinder when replacing the piston rings. That is because honing creates small crosshatches in the surface of the cylinder, to allow the wall of the component to retain oil and provide lubrication for the piston ring.

How to Hone a Cylinder with Sandpaper? [Step by Step Guide]

Have you ever wondered if you could hone cylinders using sandpaper? When you hear this at first, it might seem a little absurd. Not many people opt for such solutions. However, this is an excellent solution for you if you want to do it at your home and have no specialized tools. Getting new cylinders can be costly. So, if you have the correct grit sandpaper, you can easily hone your cylinders with them. Here, we tell you how to hone a cylinder with sandpaper by yourself. Although you can go for brush hones or ball hones if you have any. Let’s get on with the details.

Honing your cylinders is a crucial part of their maintenance. When you get something with a cylinder, they are always honed to perfection for the best fit and lubrication. However, over time with the constant movement, they can lose that fit. That’s when you will need to hone the cylinders so they sit well with other elements. You will need to hone your cylinders; otherwise, your machinery may completely stop working. Honing gets rid of all the imperfections from your cylinder and makes them function perfectly. You can use different cylinder honing tools for that purpose. But if you don’t have any tool available, then you can try honing a cylinder with sandpaper.

Can You Hone a Cylinder With Sandpaper?

After people hear honing a cylinder with sandpaper, a common reaction is, Can I hone a cylinder with sandpaper? Well, in truth, the reaction is justified since it’s a bit tricky to do the job. But that doesn’t take away the fact that cylinder honing with sandpaper is something you can do. All you need is the correct grit of sandpaper. And some cylinder honing oil may come in handy as well.

Honing Cylinder with Sandpaper (Step By Step Guide)

Among many other cylinders honing techniques using sandpaper is the least common. Not many people even prefer it. But if you are left with no choice, this can be a great option you can go with at home. Let’s check out how you can hone a cylinder at home.

1 First of all, get rid of all the loose elements from the cylinders . Please make sure they are easy to move around and clean. Getting the cylinders out is a whole another topic we won’t be digging into that here. 2 Now, put some cylinder honing oil on the cylinder walls to lubricate them. It helps in honing the cylinders quickly and adequately. 3 You can then try using sandpaper by hand, or you can combine it with a drill. Using your hands will make the job harder and may cause some imperfections as well. That’s why we prefer going with a drill. To work it with a drill, you need to make a DIY cylinder honing. 4 Get sandpaper of the proper grit amount. We discuss the grit size later on. After choosing the perfect grit size, cut the sandpaper and attach it to a drill. 5 Try attaching the papers in such a way that they create a circle when they spin in speed. It should look like a bicycle tire or a fan. Also, you have to make sure the gritty area stays on the outer part of the drill. 6 Finally, attach the drill into a drill gun and start honing the cylinders. They should work well and provide you with great results once you hone the cylinders entirely.

People don’t prefer this way because of how much work it requires. Also, using sandpaper will mostly depend on the grit you use. So, a wrong grit on the sandpaper can become a deal-breaker for this process.

What Grit Should I Use To Hone Cylinders?

The best grit for honing cylinders is a 320 grit. You want that grit because it can get through aluminum oxide quickly, removing surface scratches in the process. If you’re trying to remove deep scratches in chrome-moly steel, it’s much more effective to use lower grits since they are able to do so without removing too much metal.

How Much Can You Hone A Cylinder?

Honing your cylinders too much can have the opposite impact on your cylinders. You can make the hole bigger with too much honing. This may lead to parts not fitting in your cylinder correctly. Usually, 4 to 6 strokes are the perfect way to go for cylinder honing. Or you can try out 10 to 15 seconds on each hole. This will give the cylinders crosshatch marks that consistent throughout. More than that can tamper with the size issues.

Cylinder Honing Tips

When you are honing cylinders, make sure to follow these tips below: Always wear gloves and safety goggles before starting to hone your cylinders.

Make sure to keep the cylinder steady on hold.

Use honing oil for better results.

Keep the honing to a moderate amount. Please don’t overdo it.

Install new rings that are a bit oversized after honing your cylinders.

Final Words

The Perfect Finish: High-performance piston rings require “fool-proof” cylinder honing

ABOVE: To facilitate proper cylinder bore surface preparation and piston ring-to-bore fit, high-performance ring manufacturers and distributors recommend the honing of cylinder bores with the BRM Flex-Hone to exacting tolerances within only a few microns.

“While unquestionably vital to performance, the piston ring is sort of the poor stepchild of the high-performance engine,” says Keith Jones, Technical Expert at Phoenix-based Total Seal. “They get blamed for just about everything. If there is a compression problem, it’s the piston rings. If there is oil consumption, it’s the rings. I wouldn’t be surprised if the rings got blamed for a flat tire on the way to the racetrack.”

Jones knows a lot about piston rings and racing. Since 1967 his company has been manufacturing high-performance piston ring sets installed in racing engines used in competition events ranging from IRL (Indy), NASCAR, World of Outlaw sprint car and other racing classes. To stay informed of customer needs and satisfaction, Jones actively solicits feedback from customers, particularly questions concerning performance and critical installation procedures.

Except for its standard automotive line, the countless different ring sets that Total Seal offers are for customized engines, each having many individualized requirements, including cylinder block materials and piston ring designs. Of those, it is particularly important that the piston rings precisely maintain 100 percent contact with the walls of the block’s cylinder bores. Otherwise, performance problems such as compression blow-by and oil leakage can cause severe, if not catastrophic, problems.

Providing the needed consistent contact between piston rings and cylinder bore almost always requires resurfacing of the bores in racing applications, either because the bores are not perfectly round, have been damaged by previous ring or piston failure, or other wear factors. In any such cases, resurfacing the bores can be a challenge.

“High-performance engine blocks have changed a great deal over the past couple of decades,” Jones says. “One of the most noteworthy changes is the hardness of the block metal, which can be several times harder than it used to be. This has dramatically affected cylinder ring installation requirements because it is now crucial for the customer to achieve proper ring fit inside the cylinder bore at the time of installation.”

Jones explains that in the old days, when engine blocks were composed of relatively soft metals (e.g., 150 Brinell hardness), installers could usually rely on piston rings to adjust to cylinder bores by wearing into the bore surfaces after installation. However, this approach is no longer realistic because today’s engine blocks are much harder (e.g., 330 Brinell), while the high-performance rings are considerably softer with lower tension. The combination simply doesn’t permit that kind of “break-in” technique.

To facilitate proper cylinder bore surface preparation and piston ring-to-bore fit, Jones and other high performance ring manufacturers and distributors recommend the honing of cylinder bores to exacting tolerances (within a few microns). This procedure ensures that excessive compression blow-by and inadequate cylinder bore oil retention are avoided at the outset.

Simplified honing solution

Since bores differ widely according to block hardness, design and engine wear conditions, the proper honing of bore surfaces could become a tricky situation. However, Jones finds that rather than taking a fairly difficult and cumbersome approach of honing with conventional stones, he recommends the Flex-Hone® produced by Brush Research Manufacturing in Los Angeles.

The Flex-Hone is a ball-style tool characterized by a shaft with small, abrasive globules that are permanently mounted to flexible filaments. The tool is available in many sizes with a wide selection of grit material. It works well when hand-held because the design is automatically self-centering.

The cross-hatching capabilities of the tool are integral to the cylinder bore surfacing requirements of most internal combustion engines, ensuring that proper oil retention will be maintained in the cylinder bore walls at all times.

Using the tool, parts such as carbide bushings, bore sleeves, hydraulic and pneumatic cylinders, and other cylindrical cavities can be surface finished on the production line – or resurfaced in the field – using a relatively inexpensive tool that requires little set-up time.

“We recommend this type of hone because it works very well, is easy to use with a hand-held drill motor, and is really fool-proof for the average consumer that is not an experienced machinist,” explains Jones. “It’s really easy to screw up with an average rigid-style hone, but it’s very difficult to screw up with a Flex-Hone.”

The Flex-Hone is available in 11 abrasive types and eight grits. In the case of most automotive combustion cylinders, 120 grit works for older cast ring sets or where the cylinder has been re-bored and is a little rough. Hones with 180 to 240 grits are good choices for general deglazing where the cylinder is not going to be bored or honed. A 320 grit, and even sometimes as fine as 400 grit are often used in high performance applications with high performance ring sets.

Expert support

Because the Flex-Hone is available in a variety of sizes, as well as abrasives and textures, Jones often refers customers to Brush Research for additional technical advice or specific product and process recommendations.

“We provide this type of support all the time,” says Miller. “Total Seal’s recommends using our LEVIGATED ALUMINA (super fine) abrasive in one application which is a little different from other requests we get. Total Seal does their homework and have found a combination that works best for their rings in harder block materials. We are asked to produce many different surface topologies which is not a problem with the Flex-Hone.”

“For example, we have a customer that builds engines for the high-performance marine industry that wants a surface finish that is quite different from automotive applications. So, we ask them what Ra, Rk [roughness factors], and other surface characteristics they want to achieve, and then we identify and ship them with the tool that will meet those specifications.”

In addition to special, customized applications, this flexible hone is also used in production environments, including with CNC equipment.

In a production example that required a custom solution, a diesel engine remanufacturer utilizes Flex-Hones in a two-step operation to resurface cylinder bore liners.

“For that application we recommended one tool, a 120-grit model, to produce the crosshatched surface with ‘valleys’ that would provide the necessary oil retention,” Miller explains. “For a second honing step, we provided a 600-grit model that put a nice plateau finish on top of the deeper cross-hatching. Through this two-step process, the remanufacturer was able to bring their cylinder liners back to specification.”

Honing cylinders without removing engine?

Remove the piston and rod. I assume you have the oil pan removed. Cover the crank journal. If all you are trying to do is de-glaze the cylinder walls and crosshatch them, use a bottle brush style hone and use a smooth up and down motion with the hone.

Be sure you are moving the hone paralell to the cylinder walls, and not at an angle. If there is a ridge at the top of the cylinder it has to be removed first. There is a tool for doing this. A small rounded file can be used to do this BUT, be VERY careful to remove only the ridge.

Sometimes what would appear to be a ridge is meerly a build up of carbon deposits, so clean the area with carb cleaner and/or emory cloth (sandpaper) first. (I do not use sandpaper because it leaves a lot of grit)

When you are done clean the cylinder with soapy water and rinse away any grit from the honing. Double and tripple check to be sure that no grit is left on the crank, especially the journal. You can also wash down the inside walls of the block. I spray it with brake clean with a heavy application to “flush” away any grit (do this last ie after all the cylinders are done.

Label the pistons and rods. They MUST go back in the same holes.

The crosshatching lines should be at approximately 60 degrees to one another when you are done with the hone. When you are done with a cylinder, including cleaning, coat it with a light coat of oil (like WD 40) and cover it.

Before you begin the honing, do what ever you need to do to the deck, e.g. clean away all old gasket residue, chase the threads for the cylinder head bolts, etc. Check the “deck” for flatness with a good quality straight edge. A machinist straight edge is best for this. Is it within tolerances?

Make sure the oil return holes are clean and clear of obstructions.

This is one of those “you may as well” type jobs!

When you go to insert the pistons cover the rod bolts with bubber hose to protect the crank journal from scratches or nicks.

Make a complete list of what you are going to do, and check off what you have done when it is done. Remember, CLEAN, CLEAN, CLEAN.
