[Saloon-lovers] 3.8S Crankshaft Damper

A few weeks ago there was a post regarding a crankshaft
damper that was rubbing on the nut for the spring loaded
idler pulley. I checked mine and sure enough for about 2
inches of the circumference there was signs of rubbing.
This appears due to deterioration of the rubber between the
two metal halves of the damper. Mine was the original one on
the car from new. I ordered a new replacement and I can
report it is possible to change this without removal of the
radiator. You will need a very large box end wrench 1
-5/16ths in size for the crankshaft bolt. It will be very
tight but I was able to loosen mine by locking the car in
gear and pounding on the wrench end. Remove the four bolts
holding the pulley then the bolt for the damper. It is also
a good time to renew your fan belt as well. When replacing
ensure the crank bolt is very, very tight but I see no
torque figure in the S Type workshop manual. I found the new
damper was .75 inches thick and the old one had swollen to
.80 to .86 inch thus causing the rubbing.–

John,

Where did you find a new damper? Mine is not the prettiest thing,
looking really sad, cracked, couple of pieces missing from pully.

thanks,–
