MF 491 PTO shaft leak

MarkinMO · Mar 22, 2014

I have a MF 491 that is leaking around the PTO shaft. Does anyone know what"s involved with replacing the seal? Can it be done without tearing into the housing? Thanks.

As far as I know this tractor has the same rear axle as the 200 series Masseys? If so then you need to remove the 4 nuts, washers and the square plate around the PTO shaft There may be another thin plate to keep the bearing housing from rotating, remeve it also. Now fit a drive shaft or place a bolt through the little hole down through the shaft to lever against and use a tyre lever to prise the shaft out of the tractor. It will only be retained with a tight 'O' ring and should prise out quite easily. Remove the bearing housing and a few snap rings holding the assembly together..Refit the special seal and rebuild.........Not need to tear in any further............
