sump cotter key replacement

maxwell99 · Sep 25, 2013

while changing the hydraulic/transmission oil in my old TO-35 Ferguson tractor.

I noticed that the cotter key that has always been sticking out of the bottom of the sump housing is missing in action. (weep hole is open)

Question: has anyone ever replaced that cotter key without breaking the tractor apart.

if so, how did you do it??????????????

I have been thinking of all kinds of redneck opportunities to really screw something up by dropping a cotter key inside the housing. Then it getting sucked up into something that would later require the tractor to be split apart to repair and cost loads of money.

Thanks for your response,
Fred

I would not worry about it being missing. once a month or so wiggle a little screw driver in there. if it leaks so bad you worry about the leak then said leak needs to be repaired.

Fit a pin in the hole upside down for the time being, just spread the legs open first and then push it through the weep hole, it is no big deal if it comes out. On a TO35 you can drill a small hole on the plate covering the implement attachment pad under the Clutch, fit a pin into that and this will prevent any build up of excess oil John(UK)

Sounds like a good plan,

Thanks,

Its just a temporary thing and whenever you take the Engine out, you can fit the Cotter Pin in the correct place. It just saves you some time. Where that plate is, there is a hole in the casting and the Plate is at the bottom blocking it off, Any oil that does build up will go into the hole and run out through the Cotter Pin as it would do normally...John(UK)
