Case 731 Low Range Gear Stuck Repair

t.henrie · Jun 10, 2021

I have been looking at a Case 731. The ad indicates it was running when it was parked and that the brakes may be locked up. Price is pretty low. In reading forum posts, I came across a couple threads about the low range gear freezing up and that it is a difficult and expensive repair. Since it is unlikely this tractor that would have both brakes freeze up at the same time, I'm assuming it's the trans issue.

So, my questions are, how difficult/expensive is this repair? Does the tractor have to be split? Could anyone give me a few details as to how this repair is done and what other damage might be expected? What is parts availability on these tractors like? I'm wondering whether it would be worth trying the repair myself.

That would be a very expensive repair, I have had to cut the range ears out with a blue wrench, split yes, what makes you assume the range gears are seized, if one is seized it will drive in the seized range and neutral and lock up when the other range is selected. If it will not move with the 4 speed in neutral check the brakes, the dual range is ahead of the 4 speed and if it runs in both high and low range without stalling there is nothing wrong with the dual range.

Can't explain the triple or what ever you want to call it lol.

Thanks for the quick reply.

A few questions to the owner lead me to believe it may not be the transmission. He says he stopped driving the tractor because it had a fuel leak in a fitting under the tank and that at a later date a fellow needed to move the tractor and told him that the brakes might be locked up. So, maybe it's not the low-range gear after all. I may go take a look at this tractor.

Loosen the bolts holding the cover on the brake drum and see if they loosen up. Kinda common for brakes to lockup on Case tractors from
sitting. The boots go bad and leak water inside.
