Rebuilding cylinder liners

I think what has happened is that we are just now going through the transition where cylinder liners and bearing inventories are used up and it remains to be seen whether it is economical or not to reproduce these items. Considering how many low production items have become available for the automotive and wheel tractors markets it would seem likely that someone would pick up the market even with the low tractor production numbers.We can only hope😄

Don't know that I have ever heard of chroming diesel engine liners, maybe someone can comment. If money is no object, most anything can be done.

Well, I guess there is a service for everything. Apparently there is a process for porous hard chrome plating for cylinder liners, diesels and others. Thicknesses as much as .040 in. Redoing worn liners is not a problem. No mention of costs though. It's been 40 years plus since I had a Lincoln Zephyr crankshaft hard chrome plated back to standard and the price floored me then....no telling what to expect now.

I've had to send out a lot of parts here at work that did not come in to spec. Hard chroming is one of the most expensive "finishes" you can get on a part...

I'm not real familiar with Diesel engine liners. Can't you just machine new ones? Are they cast or something?

What kind of steel are they normally made from?

Most engine repair shops can install thin wall cast liners and bore them back to standard size for a reasonable cost, when rebuilding most engines without liners I have them lined instead of bored because parts are easier to get in std sizes. Most liners cost Aus $40 a hole installed. My Cat 22 has liners installed as well. As long as there is enough metal in the old liner to put a new one in it shouldn't be a problem.😊 😊

Wet liners are usually a very hard steel as it was stated earlier in this thread. Tolerances are very strict. Some years ago I was usuing a Sunnen CK 10 to hone a set of diesel liners and they were so tough that it pulled the feed wedge inside the hone head into 2 seperate pieces. A couple of suppliers that I have used in the past have been Clevite and Seal Power, you may try both of these and possibly come up with a set of NOS sleeve assemblies. You can expect to spend some good hard earned money but they have the liner with O rings, piston with pin and snap rings and piston rings installed. as far as boring out a liner to put a cast iron sleeve in is almost like asking the impossible, unless you can find a shop that has the machines that can handle hardened steel. Good Luck!

Can't you rough machine a liner, heat treat the steel then grind ID & OD to tolerance?

But I guess after all that, you'd be spending some cash as well...

If you can give me the seriel number from the engine I am looking into this for you and may have stumbled on something... but I have to have that number.
