Case 1370 No-Go

BarryL · Sep 10, 2013

Just posted a message about DC Brakes, got a 1370 issue as well. I just moved back to 150 yr old family farm and bought granddad's old tractors. One is a '74 1370 that I spent a lot of time in as a kid. Anyway, previous owner just died and he knew what happened to it and nobody else does, but it simply will not move. It starts and runs like a champ. But when you depress the clutch, no belch or huff in the engine like I remember. With clutch in or out, you can change gear ranges freely, no grind, just nothing. Power steering works. Three point arms raise but do not lower. If these basic symptoms give anybody out there any clue where I should start, your help is greatly appreciated!!

Torque limiter is bad

1370rod · Sep 11, 2013

The Torque Limiter could be bad but more than likely not in this situation because in these tractors it is driving the hyd. pump also. If hyd's work the limiters are OK. If this is a very late sunset or white tractor and I bet it is, the hollow shaft driving the Power Shift and hyd. pump has broke right in front of the Power Shift. This does not happen very often, I have only seen this occur 3 times in 40 yrs. Not a bad fix, split tractor between trans and torque tube and its right there. Rod

Torque limiters drive the hydraulic pumps on a 74 1370. If you have steering, the limiter is OK. The shaft from the limiters through the pump drive breaks just before the sun gear that drives the powershift planetaries. You can remove the LH cover for the extra hydraulic pump and see if the powershift is turning. If you are lucky, just need to replace shaft if nothing went through gearing.

Thanks Rod and Turbo. This is what I had hoped after looking at the service manual. This tractor runs about 185HP on a dyno, when it is apart can you give me a rough idea of what shops charge to update the powershift to 90 series? Should I worry about this or since it has held up for this long it is likely OK?

Rod,
I think you hit the nail on the head.We had a couple of failures like that with a little more smoke coming out of the pipe.

rod can you tell me where this torque tube is my 1070 seems to have the same problem it runs shifts in all gears pto and lift works engine grunts alittle when pressing or depressing I was told this was the tl and that I have to split the engine from the trans is that so /can you give me a clue I need to fix this or have it fix soon thanks

Your problem sounds like the torque limiter, you split that at the engine to repair. Rod.

Jack,

If your tractor grunts as you say that would indicate the Powershift is running and your problem could be a bit deeper. Grunting is caused by overlap in clutch engagement /disengagement and if present should have a good torque limiter feeding the powershift. A good healthy grunt when clutch is pushed in and a soft ringing would indicate planetaries running, listen for that and any other noises it makes.
