Nige,
Yes it has the rubber tracks. Thanks for the adjustment tolerance. Out of curiosity what's the idea behind the Omega mark? Is the track not symmetrical all the way around?
Also, what would cause a terrible sounding squeal every time the engine is sped up from idle to almost full power. No controls being stroked. It lasts a few seconds every time and goes away. The fan belt seems tight enough, but I can spin the fan by hand with a little effort. Basically it slips without the belt turning.
Thanks for the help,
Steve
