Amici,
A couple of years ago during the last race on the last day at Mosport
Susan's racing came to a stop due to what turned out to be a shredded
timing chain tensioner.
The timing chain and tensioner are the double row type as used in TR6
engines.
The engine was rebuilt with a new tensioner and ran one race weekend. We
had to pull the engine apart for another matter and looked at the
tensioner. It already had grooves in it after just 3 days of racing. We
replaced the tensioner at that time and she then ran one more race
weekend at VIR. I pulled the front timing cover last night to inspect
the tensioner and this one also has grooves in it, after only one race
weekend. Oiling is not a problem as everything looks well oiled, no wear
on anything else.
I called TRF today to see if they had any instock and was informed that
they have not had any since last fall. Apparently they are in search of
a manufacturer that handles quality tensioners.
Anyone out there know of a good source for a TR6 timing chain tensioner
that will last for more than one race weekend?
Thanks,
Brad
