Cas Key Thing Broke Of Cam?

[helltd]

Just finished puttin the rb30det in my 32,drove it up the street ran fine,turned it off then tried to start and failed

anyways pulled the cas off to have a look and the little key/slot thingy has broken off my cam,therefore disabling my cas,

so I'm guessing I'll have to change the cam???or does it come off somehow???

And does anyone know where I could get a rb25de exhaust cam cheap in Melbourne asap

Thanks

Were you running it without the timing cover?

It won't have 'disabled' the CAS. You can still use it on the camshaft, you just have to make sure it goes back in the right position.

I think he is saying the end of the camshaft that mates against the CAS shaft has sheared off! If this is the case then your up for a new Camshaft for sure. Are you sure it's not the end of the CAS shaft that has sheared off?

Adriano brings a good point because if you did not run the timing cover then you must pull out the little spacers or get some to suit otherwise when you tighten the CAS against the bracket it will sit on an angle and too tight, almost certainly leading to failure.

no he's not...its just a case of looking in and seeing where the tab was and lining the CAS up before installing. I had no locator in my Tomei 260's for years and never had too much trouble installing the CAS in the right position.

the factory rubber ring with the spacers must be used if not running a cover, they are available from Nissan.

I'm not sure we are talking about the same thing. The CAS has a two key drive. One is a D drive (which is what snaps when you do what he did, and the other is a star. You can still mount the CAS in place on the star drive and it will happily function correctly.

Unless, of course, he has also snapped the star drive off as well but I've never seen anyone do that before.

Which is why i asked him to make sure what was broken. I have seen sheared gear teeth before from someone who did exactly the above. the bearings in the CAS locked and it went to sh*t from there.

If the CAS was installed and running then clearly the gears were engaged. Unless the CAS was literally out so far only the locator was engaged which would be something hard to miss.

If it stalled whilst driving, then i would say the "d"drive is snapped, and the cas is stuffed
