I've just replaced all the bearings and seals and am getting ready to put this back in. I know there are several on here that have rebuilt these, does this seem right? The low speed gear, spacer and idler gear can move side to side on the idler shaft. It's not end play in the shaft itself, it's almost like the spacer between the two gears has worn. Maybe that's just the way it is made, it was like the before I took it apart also. I tore into it chasing a rattling noise and high speed whine and to stop or at least slow down some of the leaks. I'd hate to put it back in and still have a bunch of noise.
