I am looking to trade for a G6 diesel and want to know about them. I know about Molines as I had an awesome G6 LP, but I 've never had a diesel. It's really straight and will clean up really well. Were the engines dependable? Anything I should beware of? It's been sitting for years and the owner thinks the engine may be seized. Thanks for any advice.

Thanks guys. I'm starting to get excited about pickin her up. This is basically a one owner because the original owner died and his son has it now and never did anything with it after his father died. For the longest time he wouldn't even talk about selling it. It's probably the straightest G6 I've ever seen prior to restoration. I'll post pics when I get her.

I've got a few Gvi's and a MF 95 which is the same tractor; all diesels. Long wheel base nice riding tractors. Engines are fairly dependable however parts are getting scarce for them. Pistons are non existant in any oversizes unless you want to go up to a G900 size, and then the aftermarket has lots of them. Agco still stocks G900 pistons too for about the same price. The G1000/G705 pistons are too big for the Gvi blocks. The American Bosch pump is really easy to work on, Ive replaced a couple of cylinder heads/pumping units on them, with a manual, they can be done at home on the bench. Set the RPM limits for 100 RPM over stock, then bring back the other idle stop to get 540 rpm at the PTO. Watch the water pump, if the weep hole gets plugged, and the seal leaks, it will pump coolant into the gear case. Set the clutch up until it snaps over center with a positive clunk, then it wont slip under load. Drain, flush, and refill the rear end oil, they tend to take on water from time to time, and that is not good for the rear axles. Check the gearshift boot for cracks, they will vent in water. That's it in a nut shell.

I spent a lot of hours on a 1960 G-vi diesel pulling an Oliver moldboard plow. They are a very stout tractor and parts are common. In my opinion the 425 diesel was a great motor, a little cold blooded as I recall. The G 705 was the comparable replacement for the G-vi and used a larger 504 motor. The 705 tractors were notorious for rear end trouble when worked under heavy loads. The G-vi had about 20 percent less horsepower than a 705 and were a little easier on the rear end. Most of the G-vi tractors I have seen are a little rough around the edges, mostly utilized for plowing and tillage work. If it is a nice one I would purchase it. There aren't many repairs that the folks on this forum cannot walk you through. Good luck!!!

I am not aware of any problems with the 425 engines.

I would guess you could spend $1000 on the injection pump real quick. The early GVI had a bosch pump, and the later models had a roosamaster pump. I think the later pump is cheaper to work on. Or...... ditch the diesel engine and install an HD 800. They bolt right up to the diesel flywheel.

Thanks, Michael. Is the 425 diesel a good engine?
