Cummins in a 1750

[berggrenfarms]

If someone wanted to put a 5.9 non turbod into a gas 1750 do you have to change the tub? The reason im asking is because my uncle has a gas 1750 and he wants to put a 5.9 in it. He has a diesel 1800 tub and he wants to send it to the scrapper if he doesnt need it for the swap.

 

[jordan hackman]

yes you have to change the tub. sadly your 1800 tub is the wrong size. in order to do the swap you need the tub from an 1850 diesel. the 1850 perkins had the same mounts as the cummins.

Everyone talks about the 1850 tub but can you use 2-85 or 2-105 tub also?

I have a 1955 with a Cummins and the original tub. The mounts attach to the side of the tub. You need an 1850 tub if you are putting a perkins in a 50/55 series. You might have to grind out some of the tub to make the cummins oil pan fit.

Here's 2 5.9 Cummins engines in waukesha tubs. It's been done many times. Cummins and Perkins mounts are not the same.

The 1850 pictured had abnormal rear mounts due to the customer requesting that I use the flywheel housing that he had.

Working on a 1850 and a 1855 PFA right now, both using waukesha tubs.

They do tuck into any four digit frame quite easily. This a 4bt stuffed into a 1650 frame. If your uncle is interested in parts, my email is open. I can help him out with some and send him in the direction of the rest.

Eric,

Well, we'll say it's never had a implement hooked to it as was the original plan. It was supposed to be a very healthy hay making tractor, and do some tractor pulling.
At this point it needs more ground speed. 6th direct with double cut 18.4X34's and the engine pretty much free rev's mid track at 53-5400 rpm in most 6500lb classes.
I'm going to run it again this year and build a new tractor for next year, putting this one back to a farm tractor. It's all original paint and very straight, 2200 hours. I can't bring myself to make one this nice and original a fully dedicated permanent pulling tractor.
I'll put together the combination of parts and gearing out of the salvage yard to get what I'd like to have for pulling.

I had a guy ask me about at 135 tub and bellhouse, would those work for the cummins or not??

135/155 tubs are the simplest to work with of any of them. No cutting/grinding/drilling/tapping at all on the tub, mounts can easily be made to work with existing holes. The clutch housing on the front of the 3speed will work, still need the correct one for the back of the engine.

So that 135 tub would bolt right up with an oliver 1750 or other sizes? That just made a project alot easier if so.

Does a tub from a 1900 or 1950 that had the gm diesel work? I know the mounts are not the same, but the tub may clear the pan?

It'll bolt up to any 1750-up Oliver rear end, but the engine will need to sit about 4" lower in the frame for the imput shaft to line up on the Oliver rear ends.

Not sure if the pan will clear the tub, but if you don't want to do any grinding, use a perkins tub. Swapping to a detroit tub will cause some radiator and front axle issues, and the front of the tractor will sit quite a bit higher due to the shape of the tub.
