Amen! Speaking of which, I nearly got bitten by a serious flaw in the official
factory shop manual for XK120-Mark7, in the section on gearboxes. I'm wondering
if anybody has the XK140/150 or Mark 8/9 supplements?
I got it together over the weekend (the Mossbox, that is) but not without
incident. My 3rd/4th synchro sleeve has two plungers and two relieved teeth,
one forward and one to the rear, and the 2 notches in the mainshaft are offset;
thus it can go on the mainshaft six ways but only one is right. The manual says
nothing about this little fact. It just says assemble the sleeve to the
mainshaft. Apparently the paragraph on assembling the 3rd/4th synchro only
applies to the earliest SH type box, or maybe the whole paragraph was simply
cut and pasted (not on a Mac, I mean literally by some office girl with
scissors) from an earlier manual like the Mark 4 or SS100. If I hadn't noticed
this I would have got the gearbox together and then not been able to shift into
3rd and 4th. Another discovery I made was that you have to tighten the
tailshaft nut all the way, thus pulling the mainshaft bearings to their proper
places in the tailcase, and then back off on the nut just a bit to relieve the
preload on the bearings. If you don't do this the mainshaft will be too far
forward and the 2nd and 3rd gears will be out of alignment with the
countershaft gears. Once again the manual says nothing about that.
So, does anyone have the XK140, 150, Mark 8, or Mark 9 supplements to the
factory shop manual? If so, can you look and see if there is anything of
importance in there you think I should know about as far as assembling the
gearbox? I don't need to know about the overdrive, just anything about the main
gears not covered by the XK120/Mark 7 manual.
BTW, I have confirmed from two sources that there WAS a Moss Gear Company, but
I could find no other information on it, and nothing at all about the trademark
"G.G.Co.", which is stamped on just about all the gears and shafts. It's odd
that the literature mentions so many other suppliers like Lucas, SU, ENV,
Salisbury, Bluemel, Burman, Lockheed, Girling, Hardy-Spicer and Tecalemit, but
nothing about Moss.
Once more unto the breach. (Henry V, Act 3, Scene 1)
