I'm putting an M41 in my '68 144 instead of the 1970 M410 I was planning on using to replace the BW35. Project has been delayed way too long. The M41 seems the better of the two. THe M41 is ready to install. I have the flywheel, clutch, and bellhousing mounted already. I changed all the O rings in the J mated it to the M41. I started thinking about the front M41 seal prior to installing. I think I want to change it now.

From a parts breakdown it seems to show a seal, gasket and O-rings for the three housing bolts. Is that correct? Do you just pull the bolts and replace the seal, gasket and O rings? Any chance the front shaft will fall out in the process? While I'm at it how hard is it to change the front bearing. It seems quiet. Just leave it be?

The Haynes manuals suggests to install the tranny with the bellhousing attached. It says the allen bolts that hold the tranny to the bellhousing are hard to get at if you install the bellhousing by itself first. I'm not seeing it that way. The allen bolts don't seem like they will be all that hard to get at compared to the bellhousing bolts with theh tranny attached?
