Wedge List / Trans bushings
« Last post by Rob Cornick on July 11, 2017, 11:45:18 AM »
Bruce, the originals were one piece rubber so 4 required, the replacements are

urethane and come as 2 piece units so 8 required. Some of the urethane kits

don't come with the sleeves so make sure you have them before you throw away

the old bushings.

Cheers

Rob

Wedge List / Re: TR7 Cooling with AC off
« Last post by Anthony Rhodes on July 11, 2017, 05:42:31 AM »
My spider almost never has the fans come on with the AC off.  As a matter of
fact, I replaced the radiator core WHEN mine started to do what you are
seeing.

I did verify that it was not the temp sensor giving a bad reading.  The new
core fixed the problem and it runs properly cool now. The fans again never
come on.

You. Two each at four locations. One on each side of the shifter bracket.

4 at the back on the bracket, 4 at the front where it bolts into the extension

housing.

Do I understand there are 8 shifter bushings that can be replaced on the

TR7?  I see 4, is there a diagram showing where all 8 are?

thanks

Check your timing and make sure it's correct and that, if it is at the

factory setting of 2 degrees ATDC with the vacuum retard connected, that

the vacuum retard system works. If it doesn't, plug the port at the

throttle body and set the timing to 10 degrees BTDC. Retarded timing

will make the engine run hot. Also try and verify the calibration of the

temperature gauge and the cut-in temperature of the fan switch on the RH

tank of the radiator. I recently had a fan switch go bad and my fans ran

a lot more than I felt they should, which is essentially never.



The roaring fan may mean the clutch is a bit too tight. It's supposed to

limit the fan speed to 2500 RPM or so to avoid the fan flying apart from

the stress.

Hello all:



I just replaced the fan clutch on my 1980 TR7, manual, with not working AC.

Previously the car would run pretty hot and at stop lights the AC fans would

come on, so no over heating. But it would be on the high side of the gauge.

This was even in temps in the 80s F.



Now with the replacement fan clutch, the fan roars (at least louder than the

engine) at RPMs over about 3200. Even if the day and engine are cool, i.e. 70s

F. the car is running cooler. Additionally, the AC fans still come on at stop

lights after a bit of a drive.



Is this normal for this setup. (all stock as far as I can tell, except a

replacement air flow meter which seems to have a bweakb spring rate on the

gate.) I did clean out between the radiator and condenser coil. coolant level

good.

Following on from cars that do and do not have a grub screwb&.







Interestingly the parts fiche shows a grub screw on the throttle stop lever

ERC3571  - but there is NO PART number for the aforesaid screw!!!!!







I am now trying to find my old Rover SD1 micro fiche to see what they have

listed for the equivalent engine.

I have a printout of the TR8 NAS parts fiche and, as in the Rover fiche, it shows the stop lever, ERC 3571 but no screw.  It's probably the same drawing...  The hole on mine does not appear to be threaded.



I honestly don't think the FI throttle body needs an adjustment screw to regulate idle air as there is an idle air bypass with an adjustment screw on the top of the throttle body/plenum assembly that serves this function.  



BTW, I misspoke in my earlier post that the idle air adjustment is on the AFM.  It's the idle fuel air mixture adjustment that's on the AFM.
