Great work Dusty pure Art work and i cant commend Gary enough either for the work he does on the oil pumps. I had my pump sorted by Gary too what a service. And thanks to all you guys on the forum too including Norbo your expertise and time is invaluable. Cheers.

The postal strike has slowed up delivery of some parts, so whilst I am waiting, I thought I would strip the clutch basket. Some of the clutch "fingers" were heavily grooved in places, whilst others had obviously been filed down. There was a bit more rotational play than I would have liked between the driven gear and the basket too, so I bought a new Mitaka basket and rubber damper "pucks" from Norbo, and set to;

4 rivets hold the basket assembly together. I centre punch and drill the ends off on my pillar drill;

With the rivet ends drilled off, you simply knock the rivets through, and the hardened back plate can be removed to reveal the dampers;

The driven gear now lifts off;

Interesting to note this basket has the round "pucks", with 4 large and 4 smaller. Other Lc baskets I've stripped in the past have had the "D" shaped pucks. This engine is a later number, so I think Yamaha must have swapped to the round pucks on later bikes. You can see the red gasket has all but disappeared. This gasket sits between the gear and the ali basket, and is there due to the rotational "play" between the gear and the basket. It's not available as a separate part from Yamaha as they only sell the clutch as a complete unit. Forum member "Rolie" did some research and had some new gaskets made. I contacted him and he had 2 left, which he is kindly sending to me (thanks mate - top fella ) so once the gasket arrives I can rebuild the basket.
