Fot Folkes,
Get the dampener directly from ATI.
I tend to twist the TR4 well over 7K on a regular basis. I tried the harmonic
balancer from the usual sources (the one with the rubber insert...I think its
a 3 main MGB clone) and broke a crank first time out!
I then designed and supplied the blueprints for the dampener that ATI sells
for the TR4 motor and gave them the rights to sell it freely so that it would
be available to all. My original design had recessed tapered style bolts on
the front so that the heads are even with the front of the dampener in order
to allow for the maximum clearance to the rack. Perhaps ATI has changed that
aspect and if so, ask for the original setup. I've never had any issue with
the clearance to the rack, but I do run a "limited movement" trans mount.
Also, the timing marks should have been "dead on" to the olde pointer, never
had an issue there.
a little unbalanced myself...
Nick in Nor Cal

Subject: [Fot] aftermarket crank dampeners and pullies for TR4's
FoT
I have the Moss B= pulley and belt conversion with the rubber joint on the
crank pulley/dampener.
Kas warned me at Elkhart lake that these can separate and with that I would
like to explore higher quality
crank dampeners. We installed an ATI super damper on Mark Edenbs car and
there are three things about it I donbt like.
1. Cost + $ 500.00
2. They are not clocked correctly for the TR4 and a new timing pointer
needs to be fitted in a less than ideal position.
3. With the engine installed there is only B<b clearance to the steering
rack.

So with that I have been looking at OEM and aftermarket dampeners/balancers
for other cars but I just donbt know
enough about machining to determine if it would be worth trying to machine a
balancer from another make to fit the TR4.
B
While on the subject of pullies in general Ibm wondering what others have
done with non-Triumph parts.
I would prefer a serpentine belt. I know I could fit a good quality tensioner
but still stuck on fitting non-triumph pullies
to the TR-4.
Can anyone advise on this subject ?
Thanks,
jim g
