Hello , We have acquired a Wheel Horse Model 1-0394 It has been standing outside for about 10 years , the gearbox was full of water . We have cleaned the gears but the bearings were all shot . I understand the sxle ball race are not available so I have replaced them with a phosphor bronze bush which I think will be OK . The problem now is how to replace the spring loaded ball bearings holding the selectors . The first one is easy but how to hold the second ball down while sliding the plunger shaft in , Has any one done this ???? Regards Phil
