Allis 7080 overhaul opinions

So my 7080 developed a knock and turns out a rod bearing went out and it spun it.  ~4500 hours and a black belly.  Just got back an estimate from the shop and looking at just under $8,000 for the overhaul and wondering if it is worth it... bought the tractor less than 100 hours ago for $15,000 and it was a great tractor (while it worked).  Opinions on going through with overhaul or looking into a cummins retrofit or ?

Dam hate to hear that happened with only putting a 100 hours on it as the New owner

I definitely would not go for a "good" used engine.  You are taking a complete stranger's word that it is good.  That engine might last 100 hours, just like the original one did.  Get it rebuilt, then you know what you have.

Where else are you going to get a 180 hp tractor for $23,000?

Get her rebuilt and lower the rpms some. Had about the same thing happen on a 8070, put just over a 100 or so hours and blew a piston. 7080's sound so mean they make a Deere wet themselves

Guy sells the plates on ebay I think the kit is about 1200

If your gonna keep it and use it for a long time I'm in the Cummins conversion camp. We have a Cummins powered 7080 and it is a horse. Very good combination.

It'll cost money to convert. I'd just do what Dr Allis said. Someone said you can get all kinds of 180 hp for $23,000 but you'll have to eat at least $10,000 on your 7080 to get rid of it. With a knock to me it isn't worth one penny more than $5,000. In fact $3,000 would be all I'd pay if you want to sell it to me and deliver it. Economically the overhaul is your best option IMO.

Too good to throw away

I've got a good engine on my 7080, but the pump went out, and I parked it. (there's other reasons why I parked it, not just the pump) been sittin now for 2 years (exhaust covered). if you come here, and take it out, and puts it in yers. I want $2500. for the engine, if it don't run, you don't own it...bring it back for a refund!

That would be the route I would take. Buy shameless motor and use the tractor till youve got your moneys worth.    I have a tight farm budget I wouldnt be able to spread your cost of rebuild over my acres comfortably. Your operation may be different so do what you can afford I guess.

id say that's an awesome deal
7040 engine went bad and found a 70 80 engine for 2500
it was a win win

JPG....the offer still stands....ever seen a camera smashed all over a driveway? lol
