The nut on the pinion shaft is 33mm you will need a socket.
Mark the position of the nut in relation to the shaft. I did this with a cut from a Dremel tool. The oil will wash off any marks from a "magic marker"
The nut is peened over into cutouts on the shaft. You will have to bend these out.
This is a left hand thread.
You will have to remove the drive shaft hoops to move the drive shaft out of the way after you unbolt it from the bevel box.
I cut mine with an abrasive wheel. I did not want to re-weld them in the confines of the cockpit so I built a method to bolt them back in.
Used 1/8 steel 3" long cut to the width of the width of the hoops. I centered the steel on the back side of the cut off portion of the hoop and plug welded in place. Once this was done on both sides of the hoop, I put them back into position and drilled a 1/4 inch hole through to bottom stub of the hoop and the backing plate and bolted in place with a 1/4" bolt.
I have already put the interior back in, but if anyone wants a sketch of what I did please message me and I will send you one. Now the removal of 4 bolts will allow you to remove the drive shaft hoops.
Pull the old seal, put in the new one. When tightening the bolt back go slowly and tighten it to exactly the same spot that you had marked before removal. Re peen the bolt to the shaft.
