880 – ANGULAR BEARINGS MAINTENANCE For greasing the main angular bearings you can use the same type of grease used on the main gear or any other common bearing grease. Usually water proof grease is stickier and lasts longer than other types of grease (mostly on main gear and pinion). When disassembling for cleaning and re greasing make sure you are not forcing the angular bearings out from their core as they are easy to come apart. There are on purpose machined holes on the main plate and axle holder to make disassembly easier (see fig. 1 & 2). You can use Ø3mm punch tool through the holes, gently apply some force to the outer part of the bearings and push them out of their case for maintenance. V‐27 ...
