No, you don't need a rear dished plate. I have the same clutch pack on my 5spd. As long as the rearmost steel plate engages the splines on the clutch hub, you're fine.I was concerned about it, too, but the dealer showed me that it's how they come from the factory.
When did they change the design? Where did you buy your clutch pack? Never seen a factory clutch pack without the dished plates before. Who is the dealer you refer to? Surely don't want to lead someone down the wrong path. Please substantiate your claim with more info for the members here.
Okay, I have a clutch sitting here in my lap right now.If you look at the lining of the basket with the rivets in it, if that is new, it sits about a half-mm above the level of the circlip around the clutch hub.It will work if it's all new and unworn, up to the point where the half-mm of wear on the riveted lining gets below the level of the clutch hub circlip, and then the plate won't contact the lining in the clutch basket properly anymore, and there will be a warping action going on when the clutch is clamped on to the plates. There won't be full contact on the basket lining material anymore. The flat plate at the back of the stack there will get warped. You won't be able to adjust your clutch correctly.I also checked the parts book, and there is nothing in there about any model using a flat plate at the back of the stack.Whoever sold you these parts and fed you the line about them being correct was acting in ignorance, or just wanted to sell you what he had.
As long as the friction material is above the line of the circlip, it should work.Is it the correct part for that application?No.The correct part is Part #144461 Clutch Plate Dished.
both the 350 and 500 have the dished plates. memory tells me that the dishes face inward to the center of the clutch.
My "theory" on this is that they are running out of spare parts for the Iron Barrel models, and they don't plan to make more spare parts.So, they are selling off what they have, as best that they can.There are no 'new designs which haven't yet been put into the parts book' coming out for a bike that was discontinued 4 years ago. It has been obvious for a couple of years now, that things are drying up for Iron Barrel spares.
That thought gives me hope about using the 7-plate clutch from the UCE on some Iron Barrel hot-rods.
You mean you don't want to spring for Hitchcocks 550-GBP belt primary and clutch?
