axle spur gear position! (rivet heads left or right looking from the operator position?)
Original Message   Mar 27, 2010 5:40 pm
have a model 924050 serial# 066624 and the bearings are bad on the drive axle. i have the axles out and in the process had the spur gear thats splined on both sides fall out that both axles spline into.i now dont know which way the gear faces .there are wear marks with a slight bevel on one end  of all the gear teeth and don't know whether the wear was on the inside or outside of the gear to assemble it .this must be a differential drive gear or something and if i knew which way the round heads of the rivets faced(left or right) it would be helpfull. don't know if it makes a difference or if it only works if installed the corect way. the rivet heads that hold the gear assembly together are on the opposite end of the wear on the teeth.

trout. the spur gear placement is solved.after thoroughly examining the wear on the spur gear i figured something had to be causing the teeth to be wearing on the outer edge. the gear is out on the bench waiting for parts, however i slipped it back on the left axle and positioned it back in its approximate place. low and behold there was enough play in the left bearing to cause the right edge of the spur gear to rub against the very outside edge of the large belt pulley that sits in line with the axle shafts.the right side of the spur gear is dead in line with the outside rim of the belt pulley.there is even a  shiny wear ring all around the outside edge of the pully.the gear only can rub on the right side if the bearing is worn and loose.now i can put it back together knowing how it was in there in the first place.
