Coated bearings.......

[FULL FORCE]

On the last run with my engine builds last season I spent the extra money for coated bearings, i used them in all my car engines never had issues, so I never tore one back down....

I finally got to tearing down my broke engine and saw the result of using these with the added water and lack of oil....

These look like brand new and never ran!!

I will NEVER use anything but coated bearings ever again, usually when you get a ton of water in the oil you are screwed and statrt to wipe bearings...not with coated!!

I recommend using these in ANY engine built from now on....



Here are pics...

What did the crank look like? Everything I have heard says the coating is so hard, the particles in the oil scour the crank instead of imbedding in the bearing.

Crank looks perfect, I will get a pic tomorrow..

approx 50 hrs on engines...

If u would coat your pistons too,,,the block would be ok aswell 99 out of 100 times !!!!!!

A guy here local coat's pistons,,,ceramic on the top and a lubricant coating that never wears on the side !!!!!

COOL STUFF !!:USA:

any time , i got 4 winter projects here already 1 588 1 580 1 540 and 1 515. as for coating the pistons YES it works.

Nerf coating......

How much does the coating cost??

Do it yourself. if you can build an engine, you can certainly do most of the coatings.

You have to be careful as you can alter bearing clearances in some cases. I would only buy pre-coated cam bearings. But unless you're running a big, solid-roller with stupid-heavy springs, they're not any benefit.

Tyler put all coated parts in my engines two years ago. We just tore them down and the parts were like brand new. Two years of hard racing and testing. Even a poker run or two. Oil changes every 3 races.

I started coating all my two strokes pistons and heads years ago..I would never build another non coated engine again.

Mine were already coated Clevite's

Like Chris said, you need to take in consideration clearances when using coated, they can and will change, I machined mine to have what I wanted with coated bearings.

I have been using the coated bearings for a while now and they are awesome. I will not go back to uncoated. I use them for the dry start protection. Since boats sit for extended periods, I felt they would be a great addition. Obviously they have other benefits beside the dry start up, but that was my main reason for using them.

Here's a good article from EB Jul 09' to check out on engine coatings..

coating the cam bearing is good but a cam turns half the speed of the crank i like to do them all. I will leave it to the people that know what they are doing as they can keep the thickness of the coating right where it needs to be. Not sure about doing the coating on the top of the piston yourself , you might can i just never thought of it.

I've had to have cam journals reduced for use with coated bearings. That can be a hassle.

Nice, sounds like some great projects!!! I'm just doing a simple re-fresh on one of my mils since it has expired the 250 hr mark! :26:

Other than that just a bunch of drive work and shrink wrapping/winterization. I started taking in odd jobs to support the habbit.:driving:
