Price Check NH TN90F overhaul price

[Charles]

I am curious about the cost of an engine overhaul on a TN90F. I would be doing the work. I dont a have a machine shop so Id have to pay for that. The tractor I am looking at has 7K hours on it and it has a transmission with a clutch 16x16. It runs well now, but I know that stuff happens. Should I be more worried about the engine or tranny? and how bad would it be to overhauld this machine? I am talking about price for parts, and how many hours will I have spent and how many knuckles will I have busted?

thanks

Charles

If it runs decently, I would not be concerned with the engine. Adjust the valves, and run it. If it makes you feel better, have a compresion test done before you buy it. I would be more concerned with the upper main SuperSteer pivot, clutch, main hydraulic pump and forward/reverse synchronizer than any other parts on the machine.

You can go to Messick's site and price any parts you wish. I'm guessing today's engine parts pricing will be totally invalid by the time you need to buy them. Unless a balancer or front idler gear comes unglued, we haven't touched the internals of any Iveco engines save one that was submerged while running.

TN90F's had no grease zerk on the upper center SuperSteer bearing. We have seen failures before the hours on the tractor you are looking at. The parts are relatively inexpensive, but there is a fair amount of labor to change the bearing, its cap and anchor pin. FA models have grease zerks in that location.

Charles, I will give you one bit of advice. Do not go to the New Holland dealer in Sheridan, NY for any service work. Wiggers in Clymer are decent people though. I can't remember but there was a New Holland dealer just outside of Erie back when I use to travel that area a lot. But I don't remember their name or if there still around. If you do have a specific issue come up talk to either that dealer near Erie or Wiggers as they will be able to point you in the direction of a shop that can do the work (usually the shop they would use).

The TN90F is a good machine, whose farm was it on (or who are you buying it from). I know certain farms I would never buy a tractor from as the guys they have running them beat the heck out of them, if it has 7k hours and looks decent then it most likely was taken care of.

Rick gave you some good advice as to what you really need to worry about. The front axle pivot is the only major failure I recall hearing about with these tractors. I see a lot of TN-F's out of California with high hours also. They are good tractors and one of the best fruit tractors available in the US.

OH, where would I get a compression tester for this model of tractor? Do I need a special one? with special threads? Of can i get one from Autozone or where ever?

It is a simple 4 banger. They are as easy as a perkins to rebuild. Go online and check part prices. Major parts are expensive, like a connecting rod will run you like $375. But things like rings and bearings are no more expensive than others.
