Bolido Posted July 26, 2019 Report Share Posted July 26, 2019 How do you extract the pins of the mast step sheaves? The only solution I can think of is using a drill Special tool or trick? Quote Link to comment Share on other sites More sharing options...
J22geek Posted March 27, 2021 Report Share Posted March 27, 2021 Loosen rig tension on forestay, shrouds, and backstay slightly to ease mast compression on the mast step. With hammer, I gently tap pins with slightly smaller diameter, 6" length, iron pin and/or phillips screwdriver. Quote Link to comment Share on other sites More sharing options...
cdoyle Posted March 28, 2021 Report Share Posted March 28, 2021 I think that you are talking about the "roll pins". The same instructions provided by J/22 geek. Make sure you save the pins. It might be difficult to find replacements. Quote Link to comment Share on other sites More sharing options...
mikegemperline Posted May 5, 2021 Report Share Posted May 5, 2021 I just did this to replace mast step sheaves. I had two separate pins for port and starboard sheaves...which I think they all will since the sheaves are angled outboard. We had to tap #8 fasteners into the end of the exposed pin. Use lots of lubricants and some heat(didn't care about melting sheaves since they got replaced) and a gentle pull on the #8 fastener in the pin with vice grips to get the pin to slide out. Don't lose the pin and don't lose the cover plates that keep the pin captive. The hole pattern on the mast step will be hard to copy onto a new plate.

boo Posted May 18, 2021 Report Share Posted May 18, 2021 I had to drill mine out. I used a set of cobalt bits stepping up each size. It wasn't easy but got then out. Rig rite has the new style keeper plate and axle Quote Link to comment Share on other sites More sharing options...
aalkon Posted October 24, 2021 Report Share Posted October 24, 2021 Anyone has dimensions on the sheaves? Did replacing them make a big difference? Mine spin freely if lubricated, but my boat was made in 1983 so who knows the condition. Can be difficult to get the main up but there can be other causes ... Also, there is a dedicated tool one can buy to extract roll pins (actually I believe they are called coiled springs) that isn't very expensive -- but does anyone know the size to use?
