Supermate bearing job

[Winston]

I did a bearing and seal job on a Speed Queen (Primus) supermate 18 lb machine yesterday. Everything went well until the machine went into extract (with a load). The inner cylinder hits against the mounting bolts for the door lock mech, causing a BAM, BAM, BAM sound. Compared with the other Supermates, the inner cylinder appears to be positioned the same as the others. The rear pulley is pulled very tight against the rear bearing. I tried backing out the 3 bolts for the door lock mech and putting 3 extra washers on each one, in effect shortening the length of bolt protruding toward the front of the inner cylinder. I could see where on the bolts the cylinder was hitting the bolts. But the problem persists. About a year ago I had the same problem with another machine. It was solved by bending the front of the outer basket outward (in the area of the door lock mech). Tried that this time, but it did not help. Any ideas?

Was it banging before you did the bearing job ? Did it start banging after you did the bearing job ? Start disassembling and see where you went wrong. Remove the pulley retaining bolt, How much space is there between the end of the pulley and the end of the shaft. There should be almost none. Also check.... There could be a weld crack where the shaft is welded to the cylinder.

The banging started after the bearing job. There is less than 1/16" space between the end of the shaft and the pulley. The lack of clearance is clearly between the door lock mech bolts that protrude into the outer basket and the large nuts on the baffles of the inner basket. When I removed the door lock screws, I could see evidence of the scraping on the ends of the bolts. Since the original post, I have decreased the amount that the bolts intrude into the outer basket by the thickness of 2 additional washers. So far that seems to have solved the problem. But why does this happen in the first place? Why so little clearance? I looked at a spare disassembled Supermate, and the bolts protrude almost a half an inch into the outer basket. Next time I think I'll just use the Dremel and cut off the ends of the bolts.
