The cotter pin in the weep hole on my 54 had been worn or broken down to a nub. When I went to change out the hydro flue id, I was wiping down the bottom and the cotter pin went back up into the sump. Is there any way to get that nub out of there and re-pin the weep hole without having to crack the tractor in half? Maybe throught the inspection plate at the shifter or even through the plate where the hydro dipstick is?
