Hi,

Had a knocking noise coming from my engine last week, finally got round to having a look yesterday and the pulley on the auxilary driveshaft which drives the dizzy and oil pump had come loose. I removed the bolt, cleaned the threads and refitted using some thread lock, no more knocking.

Once I had re fitted the pulley I noticed that the shaft moved in and out the engine by 4-5mm, is this normal or do I have a knackered bearing or something?

Car is a 4x4 Sapphire if that makes any difference.

Thanks

 

Not normal - if you remove the cam belt, pulley, and seal housing (3 bolts), then you should see a retainer plate, fixed with 2 crossheaded countersunk bolts, that keeps the auxilliary shaft in place. There should be minimal in-out play (a fraction of a mm only).

 

As said not good, should only be a few thou, not even able to feel it normally.

the shaft is held in by a thrust plate that fits in a grouve in the shaft end, if the screws are loose then the shaft will move fwd and aft, just take off the cover (3 bolts) and have a look

 

Thanks for all the replies, changing cambelt on Monday so will take the front cover of the auxilary shaft and check it all out.
