A first for everything Case 1270

Just when you think you have seen it all I saw a new one to me when I went to feed yesterday.

Fired up the Case 1270 powershift to go feed cows, walked around it while it was warming up and there was oil leaking out of it.

Not that an oil leak is a new thing, it is where it was coming from that caught me off guard.


Right at the seam where the starter solenoid attaches to the starter oil was pouring out at about the rate of a steady pee.

To me that would indicate that the bellhousing had to be chock full of oil.

I cycled the hydraulics to the shredder and drove it ahead a few feet and the leak stopped, I then used it to shred bales for a half hour, drove back to the yard and parked it, no further leaking.

It was around -15F when I started it so the oil was on the thick side which I am sure did not help the situation.

I got to wondering is a seal that is worn or flat spotted causing the leak or could it be caused by system pressure being set too high or maybe a relief valve sticking?

The only reason I am thinking in this direction is that compared to my 970 and 1070 the hydraulics on the 1270 have noticeably more umph to them when say picking up a heavy frozen bale with the shredder forks.

Transmission pressure gauge on dash is reading normal.

Plan to do some pressure tests on it when the weather warms up a bit, just picking the collective brain trust in the mean time.

the bellhousing Runs in oil its a powershift so there is always oil at the starter,,

I am aware the bellhousing holds oil and the starter runs wet.

I would not think it strange to see oil seeping from a sealing point.

I was surprised to see it appear to be coming out under some pressure from a level as high as it was.

After I cycled the remotes and moved the tractor it stopped leaking so it seemed like something changed.

Could it be the thick oil was just not draining back fast enough and that caused the oil level in the bellhousing to get that high?

Tractor was sitting level.

It is not the oil level to high. It is the thicker oil being carried up into the starter by the ring gear.

Agree with DKASE,, I have seen them push it out more when cold,, sorry the way you wrote it I assumed you may have thought it had a dry clutch, my mistake, I missed that you already had a leak at that area
