i took the whole assy off as the lower gear bearing was making lots of noise so i replaced it..cleaned the friction plates and reinstalled and hooked it to the brushog and it makes lots of noise still with some squealing as well..the bearing on the shaft seemed good but i did notice it was difficult to get back into the housing..i had to use the bolts to pull it in farther but it got real snug about 1/16 of an inch or so before the cast flange seated..there was no gasket on it and i thought perhaps that might be the reason for the gap but now im wondering if there is something else going on..it makes no noise at all untill its engaged and then it gets ugly..any thoughts?..i will probably pull it back out tomorrow and see what i did wrong and where the shiney spots are..thanks for any input
