Agreed. B I put mine together, filled it and a year and a half later no leaks. Sealer may upset end float clearances.B

jim and other listers...



i'd be careful about putting any paste/sealer on the rear case gasket.

the proper gasket also has to do with the proper clearances for the

trans guts...talk to ted at tsi automotive before you put it back

together . his numbers is

Wedge List / Re: TR7 thermosat stuck?

Hi folks:

Just to confirm I am not missing something.
Is my thermostat stuck or a bigger problem? TR7 had been sitting for awhile. I started it up and let it idle for awhile (ten minutes?). Everything seemed OK. Started off and by 3/4 miles temp gauge started to rise! By the time I turned around and got home the lower hose had blown off and emptied out.

Refilled and restarted the next day. While idling engine temp went right to the top of the gauge and only the top of radiator was warm.
Belts are there, new fan clutch, fluid is full.

Yes, I have oranges 20 teeth ones, but Ibm reluctant to sell those.  I can

check later and see exactly how many spares I have.  Picked up a couple of

junk SD1 5 speeds earlier this summer for the bell housings that might still

have those gears in there.  If so, Ibd consider selling one.  I pretty much

only do TR8s.  TR87s are parts cars, so anything TR8 only, I hoard.

Just pulled the gears from a couple of automatic boxes.  The one with the 8cyl

bell housing has a red 22 tooth gear and the one with no bell housing,

presumably from a TR7 has a green 21 tooth gear.  Same as the Lt77 gears.

These are located in the tail housing, so its possible that its a proprietary

to BL tail housing.  But at least its a place to start looking for a

substitute gear.

Just got to thinking about this again ands was wondering, do the automatic

transmissions use the same speedo gear?  I have three of them stashed in the

basement.  I could pull one and check.  If they do, then there should be a

crossover the manufacturer of the auto trans and the LT77.

This thread here attaches a number of teeth to the color.

http://www.v8forum.co.uk/forum/viewtopic.php?t=5365  If you search LT77 speedo

gear teeth, you get lots of hits on various forums that detail out the final

drives.  The previous owner of my orange TR7 changed the speedo gear when he

went from a 4 speed to a 5 speed rear end.  He found a place that is a

distributor for speedo gears.  He mailed them his to match up.  Apparently the

shape and size of our gears is identical to some other common transmission.

He was able to get one with the exact number of teeth he needed for less than

$10.  Unfortunately I donbt know the distributor and he didnbt know what

transmission it was from.  Image searches of speedo gear turn up several ones

that look like ours, but without dimensions, I canbt say they fit.  I have a

box full of the externally removable ones, but none of the internal ones.

I've been looking but can't seem to find the answer to this one:



The gearbox I have is from a TR7. The output shaft speedo gear is white. I

need a black one. The pinion gear one looks to be black or dark blue on this

box. How close will I get if I just swap a black output shaft gear for the

white one? Guess I could calculate it. And I see red (original TR8) gears are

still no longer available? Hmmmm. Another TWOA project? Not sure I'd want to

3D print those however.

It just says to "lubricate it" but it looks and smells like it had something

substantial in it besides gear oil. This is a lightly used TR7 gearbox I got

from Tim, very little wear on anything, including the gear pump gears.

Methinks there was something other than gear lube in there.



I'm also convinced that in spite of the warnings not to use anything on the

gaskets I'm replacing, the gasket on the rear extension housing was clearly

cemented in place on this gearbox. Took me at least 3 hours of patient

scraping and gasket remover and acetone to get the old gasket off.



But I'm close to snapping all this back together and taking it to the shop for

swapping out with the poor sick box in the car now! Still puzzling over the

speedo gear arrangement and can't quite figure out how that speedo gear on the

shaft actually FITS, yowsa, it seems too snug.
