What Happens If You Don’t Hone A Cylinder?

Honing is done using a suitable abrasive gritstone on the interior of the tubing or cylinder bores. It is done to achieve the desired finishing pattern which is widely known as cross-hatching. This pattern is essential for oil retention, it keeps the cylinder interior lubricated by holding oil.

When the cylinder wall needs honing, skipping it is not recommended. The rings will wear out soon because of not enough lubrication. Again, it might put oil on your rear bumper. So, when you can barely see the cross-hatching pattern or feel it using the fingernail that’s when you should carry out the honing process without any delay.

How I Picked the Best Cylinder Honing Tool

Choosing the best engine honing tool was not easy at all. My topmost selecting priority was the ease of use so that even an occasional mechanic with little prior experience can do the job without taking any professional help. Besides, I considered their durability too. You don’t want the honing tool to break down after honing one or two cylinders if your one is bigger than a dual cylinder engine.

Different piston ring needs different grit type. While picking the cylinder honing tool, I took that into consideration and tried to cover every required size and type of stone in my review. Lastly, I prioritize the ones with high user ratings too. Some other factors were in my mind too, I addressed them in the buying guide section for you to read. All I can say, you can trust my selection and pick any of them without any doubt.

Just in case if you’re in a hurry….

How to Choose the Best Engine Honing Tool? (The Buying Guide)

With so many types of hone machines available in the market, it is easy to get confused about which one to choose. Basically checking these five features down below can make sure you have got the right tool for yourself.

Diameter

The first thing you need to consider before purchasing a bore brush is its diameter. If its diameter is oversized or undersized for your cylinder’s interior, then it will be of no use. So, get yourself familiar with your engine, its cylinder before getting a hone machine for it. Check its size from the owner’s manual. If you have lost the user guide, don’t panic. Just google it inputting your vehicle’s make, model, and year. Some bore brush manufacturers provide excellent customer support where you can consult them about the right size to get for your car.

Durable Shaft

A rigid shaft can withstand the pressure from the honing process. It doesn’t break off after getting done with one cylinder or two. Usually, silicon carbide construction provides the ultimate strength with long operational life. Don’t go for the cheap-made one for saving some bucks. They might fall off even before you’re done with the honing process!

Center Rotation

Get the one with a flexible nylon stem as the abrasive stones are attached to the end of them, which is why each of them has individual suspension. This makes the bore brush tool rotate in the true center and evenly make hone marks on the interior surface. Furthermore, they are self-aligning to the bore, preventing excessive metal deburring.

Grit Stones

The grit type of the stones also matters as it indicates how coarse the abrasive stone will be. A higher number means finer grit. Different piston rings require different grit types. So, the safest bet is to check what’s your piston rings are made of and purchase hone tools accordingly.

Pressure Adjustment

An adjustable stone pressure just makes the honing process a breeze. It lets you control the pressure on which the abrasive stones are going to scrub against the surface. On top of that, it increases efficiency which is why every premium hone tool has this feature. So, before buying a bore brush make sure it has this adjustable pressure functionality.

How to Use A Cylinder Honing Tool?

For this process, you will need a flex hone tool, a hone brush, flex hone oil, and a compatible electric drill.

Before starting the process, you need to lubricate both the hone machine and the cylinder’s interior surface. Apply oil on them generously because you are going to scrub abrasive stones against the cylinder walls. Check the owner’s manual for recommended honing instructions and intervals. You can search for the soft copy of the manual if you have lost the printed copy.

Now, select a slow speed, you only need it to spin between 500-1200 rpm. stroke it quickly. The goal is to make a 45 degree angled cross-hatch. 6 strokes are enough. Clean it off using the brush and hot soapy water. Rinse it out and leave it for drying. After that apply a light coat of oil to prevent oxidization.

If you are a bike owner, you might be wondering, how to hone a motorcycle cylinder? Well, the aforementioned cylinder honing tips applies to the motorbike cylinder too.

Those who don’t have a drill might ask, how to hone a 2 stroke cylinder by hand? Though I don’t recommend doing it freehand, you can follow the same process. You need to be quick and careful while making the strokes as you need a 45-degree cross-hatch pattern.

What Grit Should I Use to Hone Cylinder?

The different ring requires different grit stones. For example, moly-faced rings need 280 grit stones, whereas cast-iron or chrome rings require 220 medium grit stones. For the old cast, iron piston rings 120 grit type will be enough. Again, if it’s a racing car having moly-faced rings then you will need grit stones with 320 to 400 size.

Frequently Asked Questions (FAQs)

1. Does honing a cylinder make it bigger?

A: Honing is a machining process to make a cross-hatching finish on the cylinder interior surface. It also gets rid of the glaze buildups. The boring process makes the diameter bigger, not honing. So, a few strokes of hone won’t make it bigger and require a larger piston ring.

2. Can you hone a cylinder by hand?

A: Yes, honing can be done freehand, without using drilling machines. Even in factories, it is done by hand, so there is no problem if you do it by hand. However, my personal recommendation is to use a machine to get an even and consistent surface. Moreover, it carries out deburring flawlessly too.

3. What lubricant to use when honing a cylinder?

A: Honing needs a generous amount of lubrication because you are going to scrub abrasive stones against the cylinder walls. So, before starting the process use 10-30 weight motor oil. You can use BRM’s flex hone oil specifically made for this purpose. If you are working with a hydraulic brake cylinder, apply hydraulic brake fluid instead.

4. How much can you hone a cylinder?

A: 6 strokes for each cylinder is perfect for honing them. Remember to do make a 45-degree cross-hatch pattern.

Bottom Line

So, which flex hone tool you are going to buy? In my personal opinion, YOTOO Hone Tool is the best of them having all the premium functionalities. Brush Research flex hone offers you various abrasive and grit choices. ABN Brake Cylinder Hone is the most affordable one using which is a breeze.

If the other mentioned product on my list meets your requirements, you can go for them too without a second thought.
