To all you knowledgeable TR owners out there, a few quick questions.
First a little history. After driving my '74 TR6 (deduced form the
commission number) around for a couple of years now, I now realize I have
to do something to keep all of the parts together to keep it a daily
driver. After comparing the commission number to Moss's catalogue, I am
fairly convinced that I have a '74 vehicle (not 74 1/2). However, I
cannot
find any information on how to tie engine numbers to the commission
number.
Also, I find that the head number does not match the block number. The
reason that I am concerned is that the emissions diagram for a '74 motor
does not match what's under my hood, and I am concerned about ordering the
correct parts. Thus:
Did the head numbers match the engine number when the vehicles were built?
Is there a reference to determine which year a numbered engine (head) was
built?
Was there any significant difference in head design which might make one
series more desirable than another?
On another note, I am rebuilding my rear suspension this weekend, and have
seen the thread on lever shocks wearing out. My understanding is that the
lever shocks were essentially a baffle (mounted to the lever) moving in a
oil bath. I do not see how this type of system could ware out. Also, I
was under the understanding that the shock stiffness could be increased by
substituting a higher viscosity oil into the unit.
How incorrect is this understanding?
How DOES one determine if one's lever shocks are past their prime?
Also, is there any good info out there about rebuilding a TR differential?
I've read the Haynes manual and nothing scares me about it. It sounds
like
you just need to be careful. BTW, I have already rebuilt my trany (not
the
overdrive), to give you a lever of commitment.
Thanks for the info,
Scott Mackay
