A good friend and I were discussing restoring a bigger tractor today! We want this tractor sto be as close to new as posible! Now since this tractor will go back to the field to do alot of heavy work again! We figured complete rebuild of the engine and everything in front of the clutch which it would get a new clutch and everthing to go with that all the oil leaks fixed and whatever else it needed! So then we got to the tranny and rearend which is what my question is if the tranny and rearend seemed fine would you leave it alone or disassemble it and check it out since this is a complete rebuild! My opinion was to tear the rearend apart and replace all the bearings my friend says no the bearings that are in it if they aernt out they are better than any new ones today! Maybe hes right! What do you guys think?
 
It all depends on how much money you want to spend, you will be in it for 10K minimum to several times that.

Have you restored before?
 
If all bearings/shaft end play is in spec and no signs of damage, I would leave them as is. Having said that, be mindful that you may need repairs down the road; but replacing everything is no guarantee that you won't

Rebuild-restore-repair. ?? different ways to describe what one wants to do to a tractor, usually boils down to how thick your wallet is. lol. you mentioned replacing bearings in drive train--do a good search on your brand/model. [you didn't say] some tractors have a 'weak link' or item that gives up first-it may or may not be bearings. might give an idea what to look for. hours on machine, work its done, etc. someone on the right forum here that works the same machine can probably tell you what to expect. good luck & take your banker to lunch.
 
I did it with one small tractor (MH-22), complete engine overhaul, clutch, pressure plate and every bearing and seals in everything, I mean everything. It turned out to be a money pit. Should have only fixed what needed to be. Had over $4000 in a tractor that was only worth maybe $2500.
 
Welcome to the Massy club, I have several times the money in my 44 versus what it is worth.

But I really love it.
 
It would be much more advantageous to find an ultra low hour tractor of the same vintage than trying to rebuild a badly worn tractor. There are very few facilities and people who can rebuild something to the degree of precision that it was assembled at it's original factory.
 
If you have never been a transmission or a rear end you can do more damage trying to set it up back to factory spec.s with a used ring and pinion . just replacing bearings will change the ware pattern . And trying to get thhe ware patterset just wright on the drive and coast side if you have never done one will drive you insane . Then setting the back lash it is not going to come out wright . So here ya have to be real close to what it was when you took it apart same as the ware pattern. It is one of them things ya learn over the years . and yep i have made a few mistakes .
 
im in the same boat, having twice the money in a tractor as what that model will bring on the open market, BUT, can you buy a new same hp tractor with as good a quality as that massey? heck no for 4 grand in a using tractor your in for cheap i got 6 grand in my ford, but i have a almost brand new 30 hp tractor, 6 grand beats 30 plus grand all to pieces
 
yep, second that. if it is fine leave it alone. a drive and listen will tell the story of condition.
 
The title of your post is "rebuilding".

In the text of your post you say "restoring".

I would GUESS simply agreeing on the meaning of those terms would extend the thread out to about a dozen pages.

Is this coffeeshop talk or do you have the money and the means to do it?

If the tractor has been in your family since new and evokes all sorts of warm and fuzzy memories, GO FOR IT!

On the other hand, just simply throwing a lot of $$$ at a common tractor to "restore/rebuild/refurbish" it will result in spending WAY more money than it will bring when you get bored with it and decide to sell it.
 
We went through dads 1466 like that in the rear. We completely did it. All the bearings in the rear section with a new ring and pinion. We also removed the TA and put in the through shaft with the oil hole through it. With new gaskets we had about 5,000.00 in it. This had the rear section stripped to just the case when I washed it out. We even replaced the axle shaft bearings this included all seals and o-rings. We then reset the ring and pinion along with the reshiming of the axles bearings. It has been 3 years and is fine. Was well worth it.
Yes he only paid 4200 for the tractor and used it for a few years first. The ring gear was shot when we did this work so it was going to go one day anyway.
I am thinking of doing the same to my 806 next winter. I know it is expensive. You don't know what you have when you buy a used tractor. This way I know what it is.
So is it worth it if you're going to run it for several years I would do it. You will need some serious specialty tools or have some good way to accomlish some of the things. Bearings can't just be driven on and off some places. They need to be heated not hot but like in your oven.
 
not having a clue of what or how old, I can think of one threshold for determination. If it has clutch packs with seals that you are relying on to hold pressure, it would be a good idea to go in there and replace them. Not in the interest of handling the new power of the motor but just so that you can use it instead of having to park it.
 
Right on. Show me one that doesn't have more in the restore then it's worth unless it's rare and then the restore didn't cause the value. gm
 
Depends on the tractor. White 2-135,2-155 transmission and rear end,bulletproof. Some of the Masseys from the 70s,maybe a different story.
 
I used to think I could take an old tractor of piece of farm machinery and make it like new. With age I have come to realize all you have is an old piece of junk with new parts!
 
You might get more tractor life and less repair costs by going to a older tractor 20 percent larger than you need and not working it at its full capacity.
 
Hello Gleanerk2,

Your friend is right! A bearing will ether last one day of a lifetime. In chassis overhaul, if engine and its main conponents are up to specs. Spend your money on all the rest of the build.........
