Apologies for the simple question but I cannot separate the crown and main gear mounts so I can renew the crown gear.

At the moment by twisting and pulling at the same time they will only move easily about 5mm apart before stopping dead.

Am I missing something obvious? I don't want to try to apply unnecessary force at this stage for fear of mucking up the clutch.

Thanks

Sounds like you have some wear issues, Sometimes if the inner sprage gets a little worn, it will make it difficult to take them apart, but they will come apart, just work it till it comes apart, once apart, you might want to use some emerycloth and smooth it up, be sure to re-oil the bearning before putting it back together,, Good luck and keep us informed..

Thanks John.

So it should come out just by pulling whilst trying to twist it at the same time?

Job done with the aid of a soft mallet!! If wasn't going anywhere without some "assistance"

I'll make sure there's plenty of oil around when I put it back together.

Congrats,, I knew you would get them apart!! Be sure to check your shaft, and sand as need'ed.. It wont take much smoothing to get it to slip in and out!!

I use ATF automatic transmission fluid, for cars, the red kind over here, but any good machine oil will work too... XGM/VGM
