Quill handle goes on with a taper key.
Course couldn't resist trying it out. Bit of an oil leak is an understatement. So gearbox out again..
Obvious culprit was the output shaft oil seal, Remove lipped seal and measured shaft at 24.3mm so the 25mm seal that was there and I replaced like for like would explain the leak.
Stuff something in the housing while you clean off the old sealant (that is not that old its only been in there a week!)
Pop out the old seal, an appropriate sized socket makes an ideal drift. Then replace, this time with a 24mm seal. Note to self next time measure the shaft before ordering oil seals.
And replace with a bit more silicon gasket, neater job this time.
Replace gearbox, extend the quill before fitting gearbox in.
Then retract quill
before tightening the bolts that hold gearbox in place. Fit the pulley to the gearbox and line up pulleys, I was taught as an apprentice to use a piece of string. Fit new belt and grease nipples.
Had real problems with getting enough movement on the gear selector, too much play in the pin and not enough room before the lever hits the housing, in the end marked position of lever and had to drill out the pin that holds the lever to gearshaft and fit a bolt in there.
TA DAHH, and in position. Not fixed down yet but may well end up some where else so no drilling holes in the floor yet. Unfortunately the chuck is not central on its MT3 taper, tempted to give it a whack with a rubber mallet, shall have to investigate if there is a more technical way to straighten it. Now where in the chaos did the chuck key go?
