Britbike forum Forums British Motorcycle specific Brands Triumph bulletin board Motor/trans drag. Which side to tear apart

Built a t100 motor from parts, each step checked to turn free, until buttoned up.

A socket on the crank ( in neutral) turns free. But there is a bind when using the kick lever. Or when putting it in gear and trying to turn the rear wheel.

Where should I start, open the primzry,, or the trans?

Thanks

What was left to do when it last turned freely? Did you turn it over in gear at any point before buttoning it up?

Gordo

Take the plugs out, and slacken the primary chain adjuster a long way, and the rear chain adjusters, for elimination purposes.

Is the bind still present?

Possible layshaft issue? Thrust washer binding or tight bush in the kickstart spindle? On the clutch side, the clutch hub thrust washer can interfere with the clutch basket. Just a guess or two. I might be tempted to look in the gearbox first, since the kickstarter spindle has a direct relationship with the layshaft. If nothing obvious is revealed, you may need to disassemble the clutch to get the transmission out.

Just a thought Richard, The thrust washer, 8 in the parts diagram, has a locating pin. Is it mounted correctly?

Was it located? Of course it was!

Is it located now? Who knows, one thing to check

I should have known better than to ask! I'm so ashamed. I'll just hang my head and shuffle my feet.

And you NEED a porch. You gotta have someplace to stand when you tell those kids to get off your lawn.

I'm thinking midnight drag races down that driveway........GG

count me in. Gordon can help me build the porch

Found that I had no lay shaft play. That problem is solved. But the ki start lever is still stuck

I had a 3TA on which I managed to snap the kick start splined shaft/ ratchet. I got hold of another one, fitted it and put the cover back on and found that the box had tightened up. Turned out it was the wrong part I fitted. The main body of it (with the sprung ratchet part) was slightly thicker than the old one.

In neutral, does the gearbox rotate OK with the outer cover off?. You have to go around a full rotation of the kickstart to tension the spring so if clears the mainshaft as you are assembling the outer. Try it first without the spring..
