I need opinions on the best engine kit you can buy for the 433t engine. The motor us stuck and iss missing the injectors. I plan on rebuilding it myself. Also it does not have the front crankshaft brace. Where would I find one? The tractor is decent overall and has a cab so I'm thinking I goy a good deal.

Do yo know serial number. The latter ones with updated internal thrust bearing didn’t have front thrust bearing 

I couldn't find the serial number. It does have a khd emblem on the front grill which tells me it could be a 85.

Engine s/n is on a metal tag riveted to the block just above the hydraulic pump.  33-xxxxx

Why would they be any good?? They were removed for some reason. Maybe ask why they aren't in a tractor chassis. or are they combine engines ??

Sadly I'll never know the original owner died. I got involved because I'm the local Allis-Chalmers guy. I figured for 1500 I could have a nice 80hp tractor with a cab with a fresh engine

They would be core  value or less not knowing condition. They may be total junk. You don't know til tear down. As Dirty Harry says...do you feel lucky today?

Its cheap enough at $1500,,- if you do most of the work yourself , youll be fine! Good luck, keep the updates coming!

Absolutely. Some people think I should swap the motor. But if it's still able to be rebuilt I'd rather do that. I rebuilt the motor in my Allis-Chalmers 715c. So I'm confident I can rebuild this motor.

I’d say at $1,500 so far you’re already lucky! While you’re on a roll if you don’t see any obvious damage on the 2 engines I would offer a low price and hope to get them. Most combines I’ve seen in our area with those engines have less than 4k hours on them because the farms are much smaller here and not as many hours are put on them. If taken care of they are 10k hour engines before needing a rebuild. Take a breaker bar and big sockets with you and see if the engines can be rotated. Remove drain plug and make sure antifreeze or water doesn’t come out. Sounds like you stumbled on some orange gold to me. The blocks are the same but a few things need to be changed over. Oil pan, injector pump, front support bracket I think just thinking off the top of my head but you already have the old engine to pull those parts off of.

AC720Man I hope to get them for parts atleast. I think I would like to keep the original block to the tractor if possible. But who knows I may change my mind

i have many 6080's and the engines can all be bad and still run even if there is excessive crankshaft play on them. even the later blocks khd with the updated center thrust bearings  go bad in a hurry if the front bearing brace wasnt there and they left the pto handle in the disengaged position. you can get a brace for the engine at a wrecker.  the pto handle pressure pushes the crank into the block and wears into it.  i would find a good running engine out a f2 gleaner combine, you have to change some housings  and the pump but it might be the cheapest choice. i have run one of those combine conversions 15 years and its still working for me today.....

Yes my Allis-Chalmers 715c has the 433t that have those sleeves in where the injectors go. I'm hoping I can rebuild the original motor and fix up the tractor a little bit here and there
