Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Timing belt replacement

To be fair, the instructions do not mention loctiting the bolt shank although I guess that it would be difficult not to spread some here when inserting the loctited thread.

Good idea...

I have four cam sprocket lock pins for giveaway if anyone wants them, just private message me.

These are the pins you use to lock the cam belt sprockets in place while you change the belt. I have four to give away but you only need three.

The pins have been given away.

Yesterday I replaced my early idler pulleys with the later snap-ring type. I must admit that I found fitting them a bit of a pig, even though I've replaced the timing belt in the past without too much of a struggle. The lightbulb moment came when I realised that if you work the small o-ring along the thread of the bolt, the pulley bearing will slip between the stepped washers, thus allowing much more wriggle room.



Then both bolts can be done up finger tight before you push the pulleys against the belt and correctly locate the bearings between the stepped washers.
