1961Model 14 Jumps into gear when kick starting

Post by Monty1 »

Hi

I bought a Model 14 with the intention of restoring it and have commenced the strip down.

The gearbox jumps into gear when kick starting and I thought it would be a broken pawl spring on the gear change mechanism.

So I whipped of the gearbox cover and guess what, it isn't! I would be grateful for any idea's.

Thanks
Monty

Just promoting you back up the list; can't help as it's not something that ever happened when I had the 14CSR.

When the kickstart engages, it put end thrust on the lay shaft. If the layshaft bush at the other end is knackered (common problem), then the resulting movement could cause a gear to engage I guess.

You might find some useful tips in my Lightweight gearbox rebuild guide here:

Hi Johnny and Clanger

Thanks for the replies.

I will have to delve a bit deeper into the box and check it out, after reading your rebuild guide first though.

Thanks again

I'm about to remove and rebuild the gearbox on my G2.

The IFIXIT guide linked above is just fantastic, the best and most useful thing I've seen for a while and any nervousness i had about starting the job has gone.

Just thought it's worth giving some feedback given the faff and time it must take to produce the guide.

Thanks for the feedback, guys! If the guide helps you to sort out your gearbox, then I'm over the moon. :D
It's mostly a compilation of what I've learned from the very helpful people on this forum, with a bit of my own learning added in from when I finally got around to doing the job myself.

The fixit.com site is really neat: as long as you take loads of photos, it's surprisingly easy to put a guide together. Plus, anyone can edit or comment on the guides, so if I messed up anywhere, then feel free to comment or improve it. I discovered it while learning to fix iPhones and other electronic gadgets. There's not a huge amount of bike stuff on there, but I figured I'd give it a go.
