29 drive side from main shaft set up

[charvey]

Hi all,just putting my drive side together on the main shaft it was wrong when I took it apart so here we go, spacer on shaft that goes into the crankcase then the dynamo sprocket then the outer sleeve with spring over that then the inner shocker which slides onto the shaft and inside the outer sleeve then the main sprocket, the main sprocket lines up with the clutch which it didn't before but now does when tight, two nuts with a lock washer between them it does seem right without the spring on the shocker seems to work, I have tried looking for a breakdown of the parts but don't seem to be able to find anything or my internet skills are not up to scratch Clive.

Hello all, Just a modifcation I am going to fit a washer between the drive sprocket and the two lock nut as the sprocket is the slight moving part and the nuts hopefull not,unlike the last time, and a happy new year to you all and when the weather improves a bit enjoy your bikes.Clive.

We live on the edge of Rutland in Northamptonshire not far from the 2 flags cafe on the A47 and worth a visit after the 17th when it is open again and also not far from the Harringworth village railway viaduct 82 or 83 arches across the valley, Victorian building at its best regards Clive.

Thanks Roger for the photo my set up is slightly different as there is a sleeve that the inner shocker slldes inside and the sprocket part also slides into the end of the sleeve and the spring holds it all togther with a retaining lip on thr sleeve so I not sure if it is original or not but it looks right and the drive chain lines up now unlike before, thanks again, regards Clive.

On all the singles except, there is always at least one, the Slopers there is no sleeve as the sliding member sits directly on the shaft. If it all works, no problem.

Hi Roger and all,
I took it all apart so it is easier to see it, the enclosed photo shows the cup which the inner shocker slides into and then the spring rests up against the lip on the cup as there is no dogs ears for the spring to rest against.
With the spring off and then every thing back on the shaft apart from the spring the inner shocker allows the drive sprocket to turn about 9 teeth till it bottoms out on the dynamo sprocket as it rides up on the inner shocker till the drive sprocket comes up against the lock nut.
Hope that make sense thanks Roger again, good old Ariels engineering.

Your initial description listed the sleeve then the spring but your latest picture shows the parts in the correct order. Without the spring in place the sprocket will rotate a long way, it is the spring that allows the sprocket to rotate a little as it does so the resistance from the spring increases until the sprocket is forced to rotate the other way thus absorbing the thumps from the engine, reducing vibration and distress to transmission components. the 2 problems usually encountered are worn out cam faces on the sprocket and sliding member that you call 'inner shocker' and a weakened or broken spring. When the spring is in good condition it should be just possible to start the first nut on the shaft, the spring is knackered when there is enough room for both nuts without squashing the spring. Your spring doesn't look knackered or broken.

Doesn't the thin generator drive sprocket go on the driveshaft first? There also should be a grease nipple in the end of the shaft. Nev
