crank shaft pulley noise

Post by **arkright** » Mon Sep 04, 2006 8:42 pm

Hi
can anyone help please, would it be of any advantage to fit a later 1275 crankshaft pully the type with a rubber damper fitted into the cast pulley(sorry not sure of correct name for this part) on to a 1971 1098 engine eg. would it help with any engine vibration noises ? . someone asked me that question today, my own morris has 1275 ital fitted but i were not sure as to advise them maybe some one can help out there many thanks arkright.

Get them to check the pully right away as its not unknown for them to break especially if its starting to make noises.

Hi thanks for reply but is it the original cast pulley on the 1098 do mean that is prone to breaking or the later type ital with rubber isolating the two halfes of pulley that breaks , sorry i may not have worded my question very well thanks again arkright

Sorry Arkright I meant the original 1098 not the Ital type, as I assumed that was the one making the noise.

A pulley damper will at best mask the problem slightly if you've got a nasty engine vibration. They are good (they counter vibrations in the crank that lead to excessive bearing wear and possible crank failure), but in standard trim and normal driving the engine shouldn't be all that shakey.

Having said that, when I got utterly sick of my totally had it Triumph 6 pot I threw a later solid damper on and it did smooth the engine out a fair bit. But this was me working around the fault as I was fed up and didn't have anywhere to fit a new engine, whatever had worn out or broken was still worn out or broken.

So yes, the rubber cored damper is a worthwhile mod, but if the engine is vibrating that badly there's a reason for it that needs to be investigated.

The 1098 pulley is fabricated on a steel centre. They do fall apart. The noise is likely a worn timing chain. The crank damper is an excellent idea - and was fitted as standard to all East-West 1098 engines - but it won't cure a worn timing chain.
