Baffle 0 #1 Posted 5 hours ago (edited) Hello forum. I’ve been using a Hayter 21 I bought sold as seen in late 2024 regularly since last spring and I’m really pleased with it. It starts and runs reliably once I’d serviced the carb and ignition, and I get loads more cut in the same time I was putting in before, and dealing with far rougher areas too. I wondered if the power transfer to the wheels was as good as it could be, so I followed the service book to set up the clutch by setting the clutch leaf parallel with the machine body. Having done that there is no drive at all. Mine is a later model (1975 I think) with castellated nut and split pin on the near side rear axle. The castellated nut was only just being being held by the split pin and so I’ve now fitted a thick washer to take up the slack. So I guess this means that the clutch linings / clutch plate are worn out and I’ll need to dive in further. How do I get the clutch apart? I can split the primary chain - what / how would I do next? Additionally in places on various forums I’ve seen references to a Hayter clutch adjustment Service bulletin IIRC for 21s and Ospreys, but the link is to a Dropbox folder that is no longer active. Can anyone help with this? I have a PDF of the Osprey and 21 Instruction and Spare Parts book if anyone would like a copy DM me. thanks in advance for any help Edited 5 hours ago by Baffle Share this post Link to post Share on other sites
