Starting issues and noise when changing gear


Noz

Recommended Posts

For a couple week's I've had trouble starting. It would just sound like it was ticking over, then I'd get a noise which sounded like something slipping, almost a belt squeel sound.

 

I changed the main belt hoping it could be just a worn part. Still no luck.

 

It's actually got worst, and sometimes need's 2 or 3 attempts to start. Though it's not always the case. When she fires up, if it struggles I always get this squeel noise.

 

But, the noise has actually began to appear while changing gear. Not hard, just constantly and when pulling away. Considering they are both geting worst, they must be connected. Though I am unsure how components that make a squeeling noise can affect the starting of the engine.

 

Anyone have any ideas before I go on the ramps and start looking the the tranmission for any obvious signs? It sounds like the noise is coming from the flywheel area. When revving the engine (mainly on the falling edge) the noise can be heard, it's exactly the same when she doesn't fire up first time.

 

Any ideas?

Aux belt off..........hand check all the pulleys.......all should spin fairly freely apart from the crank pulley, but take a good look at this and apply the tippex test line to it.

 

If you think one is stiff, try and start it without the belt (just don't run it for long) and see if it still struggles or is better.
