cost to rebuild this Farmall 300?

Will this smokiness work itself out or am I gonna have to get the motor overhauled?

Could the smokiness be due to bad o-rings in the sleeves?

How much would it cost to have the engine overhauled?

Clutch sticks sometimes and the TA is out. How much would fixing this stuff cost?

I like the tractor, but it is old and tired.

I rebuilt the motor on my H this fall. It ran $2200 for parts. It took new (IH, more $$) sleeves and pistons, reman 8086 head, new bearings, reground cam and lifters, new gaskets and seals, new pressure plate, hoses, etc. If someone else is doing the work, it will be more.

Now the H is worth $1500, but I think that it was money well spent. I could have bought 1/10th of a new tractor that looks like a big lawn mower.

Sounds like you may need to clean up the clutch and bearings. New throw-out and pilot bearings aren't too expensive. You could probably clean up what you have and make it work okay.

T/A is rebuilds run about $400 for the unit.. get a I&T shop manual and make sure you T/A clutch is adjusted properly with the main clutch linkage. You'll have to split the tractor to replace the TA.

Sounds like you'll have a nice 300 when you're done.
