The Laycock-DeNormanville overdrive was also used in Volvos,
and their Haynes manuals have some good pictures, e.g. the
Haynes for 1982-88 740/760 has the Type J and Type P with
photos, cutaway views and a good description of how to get
them apart. It looks like the main gearbox mainshaft should
just pull right out of the unidirectional clutch, nothing
holding it but friction, just take off those 7 bolts holding
the OD to the cast iron main gearbox case, then the whole OD
should come away from it. Its not clear to me how a bad
uniclutch would prevent that. Perhaps careful application of
2 small thin prybars?
These Volvo M41, M46 & M47 boxes look like cousins of our
Jag boxes, I wonder if they were made by Moss, anybody know?
The original message included these comments:
Thanks…the manual has indicted this. Two of the studs are extra long for the purpose of relieving and applying pressure to the springs. I believe, after some input from an overdrive rebuilder, that the problem may lie in a frozen uni-directional clutch in the center of the annulus.
