Title: 1982 Vanagon AAZ Finding TDC for Crank
Post by: eaders on April 19, 2018, 06:50:38 am

Hello,

I'm having trouble finding a specific thread about my particular setup. If there is, point me in the right direction and I can erase this thread.

I have a 1982 Vanagon with a 93 AAZ and an 89 Gas M-Trans. Its the 15 degree setup from KEP with the 228mm flywheel.

I'm just getting to timing the engine. I put the cylinder head on the block with the engine almost at TDC but not quite. I wrongly assumed I had a timing hole on the transmission I could use after the fact to find TDC. I have searched high and low and I cannot find a TDC timing hole on the transmission. Does the 89 transmission have a timing hole? If so where is it?

If not, how do I get the crank to TDC?

There is a white mark on the crank sprocket, which is clearly for timing. Since this sprocket uses a keyway, it stands to reason that that white mark can only be in one spot when the sprocket is mounted on the crank. Is this assumption correct?

If so, then I think I just need to know what it lines up to; does anybody know? There is no white mark on the seal plate so I have no idea what it should line up to.

If not, how to I find TDC for the crank? Again, its almost at TDC, only off by a few notches.

Other options I thought of:
- Take the starter out and hope there is TDC mark in there
- Turn the crank in either direction hoping I can feel for it (but I have no idea how I would do this or if it would work)
- Take the transmission off to find the flywheel TDC (last resort)

Please share your thoughts, ideas, and experience! Thank you for the help friends!!

The KEP adapter should have a hole in the plate at the back side of the engine.  There should also be a matching timing mark in their proprietary flywheel.  The following pic shows the hole outlined in red.  It is an automatic ALH, but the plate should be the same.

Thank you very much!!
