On dry sleeving MM blocks I am curious

R Wyler · Feb 7, 2013

The topic of sleeving these MM blocks reminds me of my curiousity. I have been curious as to how it is done. It seems that the bore would have to remain intact in order for the sleeve to be true. It would be nice to know this is an option if ever needed.

Oh it's more than an option. Sometimes it's necessity. I've had to sleeve many blocks (the machine shop actually does it). Most recently a 4Star, one cylinder destroyed by rust and stuck. The other 3 were fine. Rather than bore all of them, we sleeved the bad one and used all the original pistons, etc. I also sleeved all 4 on a UB Special.

Sleeving blocks used to be much more popular because there wasn't so many used parts round. For instance, we have more than 150 blocks here that are very usable. Having stated that there also times we don't have what the customer needs. Dale

Yes it is a must at times as the alernative is to replace the block. My 705 is still at original bore. The bores are not perfect but it runs great. This is how an engine should be made. Why aren't all engines made with seperate blocks??

Being made like this sure makes them superior. Without good equipment like this a little guy like me starting with nothing could never afford equipment to use. Solid simple and practical is all I want or need.

I remember my uncle had heard once years ago that supposedly separate blocks were more "true" to the crankcase, but other companies seem to do just fine. I think alot of it was ease of service because you could do just what was needed rather than the whole motor, which when money is tight it is tight, and MM found something that worked (at times right or wrong) and stuck with it as alot of companies did. I had heard MM didnt make alot of tractors, but alot of their parts fit alot of their tractors..thank goodness.

That is interesting. I sure wish MM was still made. In my last post I edited it. I meant to say why aren't all engines made with seperate blocks. This is precisely the type design that is needed to operate without massive financing. The more I learn about MM the more I love them. I want to find a G900 or 1000 series lpg also.

I like the G900s and G1000s. Ive always wondered why everyone else went the opposite way of MM as a slow running engine seems practical to me. It is built for power and torque, not getting power from the speed of the engine. MM compared their engines to the "racehorse" engines of other makes, slower running speed less revolutions and less wear.

And to add to that I would match up any MM to the same class of tractor built today. Especially if all things equal you take a g 1000 that is 45 years old and see if any of these built to day are still going after 45 years later.

Yes these are some of the very best tractors ever made. And are capable of larger acre farming really. I will never ever understand why simple solid tractors are being junked in favor of much more costly ones. I am worried about having affordable tractors and equipment down the road. I don"t understand why things are going like they are.

They might last....lol if a person uses the metric system somehow, and learns how to weld plastic.... I agree Kevin.
