C4.1 build.... layshaft fouling gearbox

[Chrislong]

Hi Guys,
Ive fitted layshaft as described, ensuring the bearings are pressed in to location using a bearing press. Bearing roll freely in location - check.

Using the supplied spacer, and all 4 shims, the layshaft has a small amount of end float within the two halves.

Pair up the gearbox halfs, no other gears in location - only the layshaft, and it is very tight to roll. Upon close inspection I can see the layshaft teeth are fouling the internal of the gearbox.

Iv quickly run around the edges with a scalpal to remove any moulding bur, there isn't any anyway. No better. The fouling is significant, before I have even put any screws through - btw, just realised, no screws... (do I use the B4 gearbox screws?)

I plan to scrape away some internal material in the morning when im feeling a bit fresher. Im used to this, afterall I did plenty of this in the early stages of X-6 prototype running.

Anybody else suffering the same issue? How have you fixed it? Is it going to be dealt with by CML for future batches - or updated parts for those suffering with batch #1?

Looks good so far otherwise in all other respects. Looking forward to running it

Cheers
Chris

All i used on mine was the one spacer sanded down a little, runs as free as a b4 trans.

Its not a spacing issue, its the gear teeth fouling the internal of the gearbox casing.

Ah right, is it a b4.1 layshaft or b4 maybe some difference there maybe?

B4.1. The donor car is newish - used 5 times.
