Hi all. I'm back with another puzzler. I'm trying to replace the timing gear in my (very non-standard) Rapide. I've got a copy of the service notes, read them. I've also got Richardson and Stevens, but they aren't helping. You see the only timing marks I have, blobs of yellowing paint, when they are lined up make no sense. I'm looking at Fig. 56 on page 107 of Richardson's book, but my gear is completely back-to-front. At TDC on No 1 (rear) cylinder, my keyway on the mainshaft is at 5 o'clock, not 7 o'clock. The slots in the cam pinions instead of pointing to 11 o'clock (rear) and 6 o'clock (front) are transposed. My half-time pinion has a chipped tooth, which we surmise may have occurred when the tooth was centre popped to mark it, as there appears to be a round indent below the damage. One of the slots has a mark, but this is not the slot the key was in and if I put the pinion on the mainshaft, the broken tooth is nowhere near the paint mark on the idler. I'll try and post some pictures shortly, when they have uploaded from my phone.
