I believe when you switch to a steel oil pump gear you need to remove the circlip on oil pump shaft behind the aluminum gear before installing the steel one. Can anyone confirm?

Its not a circlip, but a 1mm spacer. And yes is removed with the steel gear!

Heh, I got so paranoid after the scare about cam gears becoming NLA, that I have two spare sets of oil pump, crank and cam gears on the shelf, despite both my 928's having new ones (well the 89 has 7k miles on them)

the oil pump gear was way worse than the cam gears and it is aluminun on my89.

For anyone who's trying them out, how are Carl's (928 Motorsports) new cam sprockets holding up?

For anyone doing this job, check the crankshaft gear. My steel crankshaft gear is worn down more that my aluminum cam gears or the oil pump gear. I was cleaning parts waiting for stuff to arrive from Roger and I pulled the crank tea just to clean around the area, gear is really worn.

Change the crank seal while you are at it.

I am about to reassemble the motor after timing belt, water pump and gears. Thanks to everyone who helped, all new gears and belt. porkensioner and cam timing done. Hats off to the designer of the adjustment tools for the cams and the tensioner. Brilliant stuff and easy to use.

I cant for the life of me, remember where this wire goes. I dont remember undoing it and the end is brittle and broken anyway so I have to assume it sits somewhere hot. I know where all the other wires go but this looks like the wire for the knock sensor but it is over by the drivers side and its junction is disintegrated as well.

This wire runs in the same harness tube as the timing belt warning light and travells to the passenger side but I cant find what it attaches to.??

Anyone got any ideas for replacing the ends that are brittle.

Maybe I missed it, but why are your cam gears black?

Why is your belt on backwards?

PorKen

Some folks say the belt lettering should be readable when facing the engine.

(Thanks, BTW!)

Dads928

My understanding was that the belt was non-directional. If that is not the case i can flip it before I start reassembling.

the cam gears are from Carl

Dads928

I still need to know what the grey wire is??

SeanR

Are you doing the testing for him on those? Last I heard they were not exactly up to spec for our belts?

We have our cam gears under test at the moment but I would not be happy supplying them commercially until at least six months of in car testing had been completed.

I checked the 928MS site and no current details on testing.

Maybe you can update us all?

Hall sensor. Goes under the cam gear plate towards the end of the plate. On the rearside is the hall sensor. The connectors are fixed by a bracket and locked by a clip.
