I purchased the lewmar service kit and pulled the drum from one of my older (1970's) Lewmar 7 winch. I know I need to replace the prawl springs, but I can not figure out how to get remove the prawls. I tried just pulling them out and they will not come out - is there a trick?Also - this is just the first one, and according to many pics, there are typically a set of berings around the main shaft. Mine does not have any bearings - I am guessing this is normal and maybe bearings were added later - or for winches "better" than the 7. Sound right?Thanks!
