Hey All,

had a scoot through a few posts and also pages in the gallery section as well as on the web but alas, didn't find what I was looking for so, time for a new thread post.

Has anyone got a 80+ HP MFWD tractor that can post some pictures of the front axle and how it attaches to the engine / tractor body / flywheel housing / whatever?

Want to try and get ahead of the curve when it comes to installing a new 140HP engine into a part built MFWD tractor and what challenges I'll be coming across

My front axle looks like the attached

thanks in advance

Plug

I would expect the front axle to be driven off a shaft coming out of the transmission/transfer case if it's got one, as for it to work, it's got to be run at the correct relative speed to the rear wheels.

It kinda looks like that front part bolts up to the bottom of the transmission bell housing, so maybe look just underneath the bellhousing and see if there is a corresponding spot for that to go into, or for a short driveshaft to connect up to the transmission?

Hey Dave,

your right in that there is already a drive shaft at the bottom of the bell housing to connect to and I have that piece and I agree that on initial look, I too thought the front part would bolt to the transmission bellhousing but the bolt patterns don't seem to match up. Havent managed to mate them up yet due to snow and now mud...…..

I have seem some pictures that show the front part bolting to the engine such that the engine is part of the tractor structure and other pictures that show the front part bolting to rails that then bolt to the main part of the tractor - I don't have any rails though

I'll keep looking, my next thought is to check out a couple of tractor dealerships and see how its done on other models

Surprised that I could find anything on youtube, maybe that's my prompt to post a video :)

Yeah, bolting it straight to the gearbox housing would make for a pretty short wheelbase.

Either they would have a frame that goes in between these two parts, and the engine sits on top of it, or, they made for the engine to "be" the frame between these two parts (like older tractors I've seen).

You probably don't want to do "use the engine as part of the frame" with the Cummins you have coming in, and since you can't find the frame rails in the parts you have, I think it's probably fabbing time. You could start with making plates that will bolt to the the gearbox and the front wheel mounts, then I would suggest waiting until you get the engine, so you can fab this frame from the gearbox forwards (so the engine crankshaft is aligned with the transmission input shaft and is the right distance from it for whatever clutch you wind up using), and clears the engine going forwards so you can still work on parts of the engine without having to remove it (ie maintenance and repairs), and then position the front piece so when the front wheels are mounted the tractor is about level.

See, it's simple.

Edit: you may also want to go back to the specs for the tractor you bought, to see what wheelbase it says the tractor has, so you can make it at least that long for stability...

Hey thanks buddy, never thought about checking the wheelbase length, smart idea, now if only this mud would dry out, I'll be able to do some ****

You might also see if a parts diagram/breakdown for the whole tractor is available (say, with the/a engine it was built for), so you can see what they had originally, might help you figure out what and how stuff has to be fabbed.

Got a couple of pics from the manufacturer that I thought I'd post - this is with their engine installed, not the 4BT that I'm going to try and install. Thought it may be useful for others seeing as I spent hours trawling the 'net for something.
Tractor is a 100-130HP MFWD
