Hi Folks,
Fitting a header pipe to my LM1 and there are two semi circular thingies that push the exhaust flange in to the head. They are flared and it looks like the wider ends face out and fit in the iron heat dissipating collars. Is that correct or is it wider end inwards?
Second, I can’t find a torque value for the flange nuts that secure the heat dissipating collars to the head studs. Any help appreciated.
Many thanks!
Dave
Found the answer. Usually the flared ends of the split collar go outwards towards the sliding collar. No torque setting, just enough to squeeze the new (ahem…) exhaust gaskets, then check for tightness after running…
Yep…
The collars have a slot around the inside, the spacers have to click into that slot else if uneven the collar could fracture when tightening it down. Sometimes I’ve had to file the corners down a bit off new ones so they go into these slots properly. Has also helped a lot to join the spacer halves together with two bits of masking tape, else one or the other keeps falling out while I’m trying to hold all 3 bits together at once and push them all into the head! The tape burns away on first start up.
