I thought this had been thrashed to death years ago, but now I’m
confused - OR, the XJ40 on-line book is still incorrect in respect
of the assembly sequence of the transmission (rear engine) mounting.
It has long been known that the Haynes manual, Chapter 7, Section
7, which has a series of pictures showing the dissassembly
sequence of a worn tranny mount is incorrect in stating
that ‘Refitting is the reverse of removal’ because in the worn
mount they are dismantling, the large foam buffer appears to
have ‘slipped’ and is shown in the incorrect position in relation
to the central spring cradle.
I had thought that this had been corrected in the write-up in the
XJ40 on-line book but apparently that shows the incorrect assembly
sequence too. Reading a number of Modern list archive posts on the
subject and by reference to the parts catalogue, the correct
sequence of assembly is as follows:-
Starting from the crossmember(‘gearbox mounting bracket’ in Jag-
speak) and working up:-
- Spring cup, lower (large)
- Spring seat, lower (rubber ring)
- Coil spring, lower (white/ green colour code - larger dia.)
- Central spring cradle c/w locating centre weight.
- Foam Buffer
- Buffer (retaining) ring (sometimes with travel restraint strap
- Coil spring, upper (white/red colour code - smaller dia.)
- Spring seat, upper (rubber ring)
- Spring cup, upper (attached to transmission housing)
Unless anyone disagrees with this sequence of assembly of the
transmissdion mount, I intend to ask Pascal to correct the XJ40 on-
line book, section 8.2 (which currently reads the same as Haynes!)–
