PTO Question on M Farmall

CHIEFEAVES · Jul 28, 2009

I removed the PTO to replace the oil seal and when I removed it there was a washer (spacer) on the end of the shaft. Question is was something else beyond the washer that perhaps fell off when removing it? I finally got all the parts and reassembled the PTO. However, when I got it back in, the PTO does not move when you engage it. It appears that everything lined up in that there seemed to be no presure on the plate when running up the studs. Any suggestions would be appreciated. Harley

What doesn't move or rotate? The engaging lever on the outside of the PTO casting or the PTO shaft? If it is the lever, you may have lost the ball for the detent. In that case, the spring is bearing against the pocket where the ball should be.

The washer is a thrust washer between the countershaft and PTO shaft. There are no other small parts at that location.

Goto caseih.com for an exploded view of the PTO attachment.

The shift lever works fine. It is just that the shaft is not making connection with any gears within the housing. Is it possible that I have the shaft in wrong, even though it went in flush when I ran the studs up. They ran up real easy as though there was no strain on them. Harley

It would help if we knew what year the tractor was made. It appears the early PTOs (at least on the 9 series) did not have a bearing lock nut that would hold the PTO shaft from sliding fowards or backwards over a small range.

I just disassembled a W-9 PTO. After I removed the shifter tube, I pressed the solid PTO shaft out of the housing and bearing. I could have pressed from either end. There was no nut, thread, or snap rings to hold it in place. Later units have a land that positions the bearing. The other side of the bearing is secured with a nut and locknut. Threads are cut into the PTO shaft.

If your shaft is like mine, it may need to be pressed further onto the bearing.

Another consideration is the shifting fork is not properly installed in the shifting tube fork collar.

Look for another part that fell off. There was a conversion kit for these tractors which had a seperate drive lug that could fall off upon removal. Early models had a lug drive, later had spline so they made a kit to convert early ones with out replacing the lower shaft in transmission. This may be your problem.

Thanks. I found the lug. Is there any special way to put the shaft back in without dropping the lug?

It is a 1939, however according to th4 diagram it has a later model shaft which has the washer at the end, which the orginal did not have. Also, it is the standard shaft that is used on later model tractors. Harley

Thanks. After 3 hours of trying to line the shaft back in place, just as I was fixing to give up and go get my mechanic friend, it fell in place and now it works (who says God can not do miricals). Again, thanks for the help and you all have a great day. Hsrley
