Well I rebuilt my SN-89 last winter. I replaced the balls, races, & the impeller shaft. I left the bearings alone however. After about 1000-1500 miles it began to make a noise which sounds like the bearings are going out on it.
This noise began when the unit heated up at first then began to make the sound all the time.
Can anybody confirm it is the bearings based on past experiences? I have not yet opened the unit up. I think at this point I should replace all of the bearings. I plan to open it up this fall but want ideas before I begin.
Thoughts and pointers are welcome - thank you.
