TD42 manual: clutch problems associated with heat?!

Post by Gabriel »

Hi all,

I've put in my comp car the TD42 engine. I also replaced the clutch (entire kit fron Denco). I had a comp last week-end and I had problems with the clutch...I mean the clutch was not working, from tiem to time. If I changed the gears rapidly, the clutch didn't engage. If I changed gears more "softly", then waiting a litle bit and THEN accelerate, was fine. When the clutch didn't work at all, I tock down the pression from the clutch pump by unscruwing the pump aerator. Some guy told me that because the clutch tubes pass closed to the exhaust, maybe the liquid became too hot and thats why the clutch didn't worked well....

Any comments, please?!

Thanks, Gabriel

someone else mentinoed this with the lines running close to the exhaust...
that was his issue.. If you can re-route, or heat shields it will fix it.

So, it means that the heat is really the cause of this problem...Any other posible causes?

Some versions of TD42 had a large heatshield around the exhaust right up until the next to the gearbox. Wrapping some of heatproof tape around might help, but yes heat is a killer of seals in the slave cylinder. Check also, the crimped join in the flexible hose that joins the hard-line to the slave cylinder--mine had a slight leak here which gave me hard gearchanging problems..

dirty clutch fluid.

Sticky fork.

Fork not on properly

rubber around the fork detoriated and blotched up with dirt.

Mud in bellhousing causing clutch slip.

Bout the ideas i can think of.

Sorry for the hi jack but my clutch pedal becomes jolty to operate after 4wding for a while. Could this be due to heat as well?
