International driven shaft has moved

[ShaneGreen]

Hit a big rock while bush hogging and it snapped a blade on the mower. Replaced the blades and mowed for about 45 minutes when the PTO stopped turning. Tore down my B275 and found that the snap ring had broken. It had also snapped the tube of the bracket that holds the PTO engagement lever (this had been broken by a previous owner and the weld had given out).

Finally got everything back together and the lever wouldn't move the gear far enough to engage the pto. Had to bend the lever so that the gear moved an extra quarter inch.

Put everything back together, started it up and couldn't put the tractor in gear. The clutch pedal moved freely, not making contact with the clutch. Pulled off the access panel and sure enough, the throwout bearing was moving fine. . .just 1/4 inch shy of touching the clutch. Looking along the driven shaft (the large one that heads to the back of the tractor) and sure enough, there is 1/4" of bright shiny shaft exposed where it should be in the bearing between the two halves of the differential.

I'm sure I've called everything by the wrong name, but I hope I've explained enough that you can understand what I'm facing. Why would the shaft move a quarter inch forward? Is this a problem?

I've adjusted the clutch pedal and everything seems to run fine now.

I do not have info on that tractor, but on a similar IH tractor, I finally realized it works, it ain't wnat everybpdy says it's s'posed to be, but it works, it doesn't make noise, or grind, or whine, or leak, it works just fine, so I just leave sleeping dogs lie and go on. Wait for what happens next.

You hit a rock, hard enough to break a blade on the mower and break the snap ring on the PTO.

The PTO wouldn't engage by 1/4" and the throwout was short of engaging by 1/4", and there was 1/4" of shiny shaft exposed. Sounds related to me.

Who knows what kinds of forces were imparted on the driveline by hitting that rock?

Sounds like the whole thing was shoved ahead by 1/4" somehow. Or the whole rear of the tractor has slid back by 1/4".

Make sure the tractor isn't coming apart at the clutch housing! I'm not familiar with the B275 so I don't know if it's a conventional design, but on typical old tractors the throwout bearing is mounted to the bell housing, and the only way for the throwout bearing to come up 1/4" short without bending or adjusting the rod from the pedal to the throwout is for the whole tractor to slide backward by 1/4".

You've got a lot of stuff that's moved by 1/4". That's not good.
