I would like to know the differences of the T-340 motor and a 340 from a tractor. Will they interchange? Will kits interchange? I bought my T-340 with a locked motor, exhaust pipe was undersize and slid into the manifold, lots of water in the crankcase. I hope this will be another of my "saves". Thanks in advance.
 
If your tractor is a diesel the two engines are the same. Bothe the diesel crawler and tractor carried a 166 cu in engine.
 
alternator & water pump may be different sizes. Typically dozer motors require those parts to be heavier than tractor parts.
 
A tractor block is different then a crawler block tractor is rounded at bell housing crawler is straight
 
I know with older T6 it matches with W6 and M with little swapping of mounting plates, and a few other small things. Can't say for sure on 340's but if you have access to both measure them up or better yet put them side by side and compare if you can swipe and transplant parts off of the bad engine on to the good tractor engine. If not close enough, rebuild the one you have.
 
Blocks are different--I found out the hard way after I bought one from a tractor-bellhousings are different even though both say c-135
 
C-135 engines were used in two tractors that I know of, 404 and 340. These are very different, 404 based on the farmall C frame, and the 340 on the H. Of course many changes followed. 404 used round clutch housing and 340 what some call straight. Look at your machine where the engine bolts to clutch housing and you will see that it is flat along the sides. So you can use an engine from a 340, and more than likely a C-153 from a 504 tractor. Many use a C-153 in Super C's, But one can't use the ones from 504's because of the straight sided housing of the 504. All said and done-yes you can use the engine from a 340 tractor and if engine is already pulled out make sure it is straight sided at the rear.
 
Do not understand. I have not emailed anyone about buying a motor(is my memory failing?). I am intend to install a kit in the motor I have. I was checking options if the block I have is bad.I am familar with C113 and c123 engines this will be my first c135. I only buy non running C or SC tractors, make them run and keep them for my use. I now have 20 of them. I bought this T340 for a bigger challenge.
