Shame about the BMW, but it sounds like it was the right time. Maybe one day you’ll get the TriBsa sorted, it could be a great project.

Sad day as I've sold my BMW R1200R.

I had not ridden it since covid struck, and my left hand was no longer strong enough to operate the clutch lever for more than short periods.

To be honest, I should have sold it a few years ago, but thats life.

Still got the TriBsa scrambler, but thats in a sorry state after sitting in a damp garage for 10 years and totally neglected.

Philip - do you still have the Goldie?

Hi Baggo, I've never had a Goldie, you might be thinking of Steve S, although I don't know if he still has it.

Hi Baggo, I've never had a Goldie, you might be thinking of Steve S, although I don't know if he still has it.

I could have sworn you had a Goldie in trials/scrambles trim. But I could be wrong - I often am these days. Something to do with advancing age I imagine. And it is advancing at a frightening rate for it is now almost 25 years since I built my WAD 6550. Tempus fugit and all that jazz.

Stay well, old friend.

Ah, my scrambles bike is a TriBSA with an A10 frame and 650 pre-unit Triumph motor. BSA gearbox and Ariel swinging arm. Forks are Norton roadholders with Betor internals.

This is the "heap" that's rusting away, totally unloved in my damp garage, sad to say.

No doubt it will be sold as a garage find project.

I know it's been 5 years, but gradually getting closer to pulling the crankshaft of the Bantam.....

Then I got sidetracked by the clutch. Several new bits needed, clutch plates (original cork nearly down to the metal, plain plates rusty where cork linings had been left 'parked' for years in wet shed); pushrod 1/4 inch shorter than it should be, so new one plus the 'mushroom' end, new adjuster screw and locknut for the worm actuator (previous mangled), plus new ball bearing (goes between adjuster screw and pushrod - previously two had been put in because the pushrod too short). Clutch springs 1/4 shorter than should be, and misshapen, so now on order plus 2 plain plates. Pushrod should also have a bit of rubber sleeve covering it between the actuator worm and gearbox output shaft, to protect it, else 'hanging' in open air, but was missing, so got one of those.

I am debating whether to remove the clutch basket, the ball race is not horrible but if it could be replaced might be worthwhile doing. I've dicovered my spark plug socket is a perfect fit for the (deeply!) recessed shaft nut, and I have the clutch centre holding tool, so why not.

Onwards!

No reason not to do it Mike.

h'aporth of tar and all that.

[Mike H]

Quite so.

Well it's off.....

Clutch basket cleaned up more betterer (than it was) ....

Ball races really not bad, if used, but will look at possible replacements. The gearbox output seal is brand new, altho that would have been quite easy to change, just take the seal holder off.

[Mike H]

Was struggling to separate the crankcases, and ruined one of the 'posh' dinner knives by using it as a wedge (to get into the joint), then I found yet another hidden screw.

That's happened to me before (but I remembered those ones this time).

Fun fact: I discovered my 21mm spark plug socket is perfect for the (deeply!) recessed clutch hub nut.

All bearings and seals appear to be new - apart from, as mentioned, mainshaft clutch side bearing - possibly 'previous restorer' couldn't get the snap ring off (but no signs of any attempts to do so - scratch marks etc.). I've got Knipex circlip pliers on order, but if that doesn't work I think the bearing is staying there.

Well I dunno – I pulled the gear clusters. and the bearing is perfect. So play had to be the shaft in the inner race. (?)

So, all bearings and seals were recently new - interestingly two bearings I can see writing on say 'Made in England'.

Alrighty then! Still need to get crankshaft rebuilt if poss, to replace big end roller race. Place I'd like to take it to is on holiday 'til the end of the week, then it's bank hols, so will find out later.

The Knipex pliers arrived this morning, but still 'won't look at' the snap ring. But with the crankcase turned over, I realised the bearing is pressed in from the inside. OK then! So if it's tight up against the snap ring, that's why the latter won't budge. But all academic now since bearing is good.

Spent most of the afternoon removing sealant off of the mating faces. Gearbox output shaft inner gasket was so old it was almost fused to the metal. Was probably stuck on with shellac! But got it off. Crankcase joint faces had been sealed with some horrible grey rubbery stuff, but came off with a Stanley blade. Only did right side today, that was enough!
