Urgent help needed with Cam gears please

[DR.ZOIDBERG]

Hey Ya!

I have a set of Os Giken Cam gears for my R32 GTR, I am told these gears fit all skylines (Rb20, Rb25 & Rb26dett). Once I installed these gears on my GTR, put the belt on and clear cam cover and crank engine sensor, started the car my mechanic noticed a slight sound, found it comming from the crank angle sensor, he pulled the crank angle sensor off to find it had been rubbing against the gear, made a nice little mark on the Crank Angle Sensor aswell

Have we got the wrong gears for my car??? or whats going on??? any ideas?

I rang the place I got them from in australia, and they tell me that OS Giken use the same cam gear for both sides (In & Ex) so that the same gear gets used for both sides but 2 of them. They tell me they have never fitted them to a gtr before and dont seem to have a 100% reason why they would be rubbing against the crank angle sensor.

If anyone out there can help me ASAP I would more then greatfull as I want my car back on the road bad

Let me know what you think please

Thanks

You shouldn't have a problem with the cam gears.

I'd put the factory cam cover back on (leave the adjustable cam gears on) and see if it still does it.

The only reason they should rub is if the clearances are different, and the only thing between the CAS and the cam gear is the cover.

I have seen another set of adjustable cam gears rub against the CAS, althouth these ones were stock cam gears modified to be adjustable, and the nuts/bolts that were used on them to make them adjustable was where it was rubbing against the CAS.

To overcome the rubbing they put spacers (washers) under each of the 3 bolts that hold the CAS to the cover/gear assembly. It gave enough clearance for it to stop rubbing.

I hope that helps.

did u use the original rubber seal that is fitted to the cover behind the cas, if not u need to remove the small steel spacers fitted into the rubber, it has to have these spacers otherwise it will rub on the cam gears, if u dont have u can use washers, u need spacers about 5mm long.
