Clutch / cush drive / chain install

The photo below shows the crownwheel, clutch spider, drive sprocket, dog, spring and cap installed. There are a few things wrong here; if you fit them like this you won't be able to fit the chain, and also the top chain guide is bolted above the bottom and it should be the other way!



So I had to undo the crownwheel and spider to fit the chain:



After stacking up the steel and cork discs of the clutch onto the clutch flange on top of the springs, I compressed it all with my cheap clutch compression tool. I used a socket to spread the load as it was pressing one side further down than the other:




When partially compressed use a screwdriver to nudge the springs into the correct seated position. When fully compressed you can fit the large circlip to hold it all in. Make sure that the end is covered by one of the lips of the spider.



I undid the chain guides after this and placed them correctly (the upper one beneath the lower one). Correct adjustment of the upper guide should give you around 10mm of movement in the chain between the guide and the front sprocket.
