new lambretta chain tensioner

[rocho68]

heres some pictures of a new roller type chain adjuster that myself and chris sturgess have designed , it helps when messing about with stretched chains and different sprocket set ups and it gives 24mm of adjustment .




It is currently being tested by chris so hopefully more news soon !!!!

yes its quite simple , put the bottom countersunk bolt in and set the chain tension while the clutch nut is off then pull the spider out of the clutch which then frees the chain so you can put the top countersunk bolt in tighten up and put the spider back in , roller set and away you go !!!

Thanks for the prompt reply.

I note that the roller bearing is shielded. From my limited experience, shielded bearings do not like running at the same speeds as open (oil lubricated) bearings, such as the drive-side main. Given the size of this roller, I guess it could be turning a tad faster than engine speed, which might be too fast for a shielded bearing.

However, even if this did prove to be an issue, avoiding such a problem might be as easy as popping the shield out of the bearing.

Keep up the good work and posted on the testing.
