Cheers Matt.
Previous to this motor (i.e. the other two that I cooked) I ran the stock spur and pinion was 22
(i.e. 83 / 22)
but occasionally dropped the pinion to as low as 18.
This still was 80C+ hot!
Thats when I thought that I might have geared TOO low, but last night was high geared and still hot.
Argh.
Belts too tight - to be honest, thats one area of the Cat that I always thought was never explained well.
I have no idea what to set the eccentrics at as it doesnt mention it in the manual.
So, the rear is set so the little dimples line up, whereas the front feels too tight when I do that (and the layshaft clicks) so I slackened it off by one "click" on the eccentric.
(hope that makes sense!)
I was told by another Cat driver that if you can turn your belts over 180 by your hand (i.e. grab the front belt and twist it so the "teeth" are pointing up at you; then its too slack, but with mine you could easily do that.
So I dont think the belts are tight?
