[QUOTE="craig, post: 131291, member: 1959"] I am trying to best to fully understand the instructions for crash damage in Paul Richardson's book page 40. I have edited this page 40 text for my clarity. My"twist" appears to me to be 7.0mm/ft [B]Crash Damage[/B] Slight lateral bending can sometimes be corrected by heating the tubes adjacent to the lugs and re-setting each fork end individually. Mandrils inserted through the pivot bearing and the rear-axle slots should be parallel, and the maximum permissible twist is 3/32 in. (2.38 mm.) per foot of mandril. The inner fork-end faces should be parallel, 8.3/8 in. (21.27 mm.) apart; the right-hand face (purple) is 9/16 in. 04.28 mm.) outside the face of the pivot-bearing lug, the left-hand side face is 1.1/4 in. (31.75 mm.) outside the left-hand face of the pivot bearing lug. The apex lug (yellow) is central to the fork ends, and the ears of the seat-stay lugs should also be parallel. [ATTACH type="full" alt="MO22cropRFM3.jpg"]38946[/ATTACH] Is there a how to article on replacing the fork ends on an RFM? Can you unbraze a fork end by heating it and pulling it off? [ATTACH type="full" alt="RFMRearLugs2.jpg"]38947[/ATTACH] Are there dimensional drawings of the RFM that can more accurately describe the dimensions? Top view? Side view? Pictures of disassembled RFM? Depth of bore, engagement joint of brazed joints? Tubing dimensions? Suppliers of tubing? [/QUOTE]
