I installed the new Borg and Beck clutch in my 79 Spitfire. In the
process I did a couple of things I omitted in previous clutch
replacements:
1. I drilled out the bell housing bushes that hold the release lever
pin and replaced with new tight ones. I went a size larger, too, 3/8 id
and 1/2 od.
2. I drilled out the lever release pin hole to 3/8. It was all worn
and not round.
It all works great!
Also, just for those who don't know, use the guide pin method of
installation.
Cut the heads off of two 7/16 x 2.5" bolts. Grind the cut end to a
bullet point and screw the thread end into the two top bell housing bolt
holes (the outer ones, not the center one)
Insert the trans into the car via the rh door, tail high to get the bell
housing under the dash. Leave tail pointed toward rh seat until bell
housing is forward to right side of firewall cut out. Swing tail end to
near center, resting the bell housing on the frame.
Jack rear of motor up 2". With a wheeled floor jack, elevate
transmission to equal height and slide forward onto the guide pins.
Adjust the jacks to assure the bell housing plane and the flywheel
plane are parallel. This will align the spigot shaft and crank
bushing. Slide the transmission home and bolt it up! Remove the guide
pins and install the correct bolts.
This is a thousand times easier than wrestling the weight of the unit to
align all the parts. Some TR3 guy told me about this method. It will
come in useful for the new people on the list.
Thanks
