I am stripping this unit and have a few questions.....

1) how does the drive/steering unit come out? Is there some type of locking plate on the top then it drops out from the bottom or?

2) how does the mast come off the unit? I see one row of bolts near the top of the unit, a second row in the battery area and a third row below the unit. I also see two welded ????m (pins) in the battery area. Are these just locating pins or did someone weld two bolts in ( there are 4 empty holes in line with the welded pins).

Does anyone have a manual on this unit. It is 30 years old and I have not been able to come up with one yet.

Thanks..... Mike
