1098 engine, 948 gearbox....

[ianmack]

I’m just assembling a 948 box with 803 change to the 1098 engine of my 54 series 2. Using the thinner pressed steel engine backplate the bolts will be too long in their blind holes. Suppliers only list one type of bolt so I shall have to either cut off the bolts or fit additional washers under their heads. Washers would be simpler but of course I don’t want to risk fouling the flywheel.

Has anyone done this lately, ahd how please? I guess washers are no problem for the plate to gearbox bolts as there is more clearance.

The correct length of the set screws/bolts (Pt No: HZS0505) used with the pressed steel rear engine plate is 5/8" long x 5/16" UNF.
There is a good chance that the bolts with additional washers would foul the flywheel as the rear face of the flywheel is not recessed so as to clear.

Thanks Phil. The same size in fact as the clutch plate bolts of which, as luck would have it, I have a spare set.

You will need qty 7 for the rear plate.
The bell housing rim bolts are slightly longer.

Yes, a clutch set plus one from the odds and sods box - perfect!
