Leslie 330 lower rotor shaft removal / replacement

[Tim_at_Jonas]

Same bearing system as in the 122A (of which we have six, five of which are over 13 years old). I remembered that I've had the rotor out of a couple of these to fix rotor rattles, so I checked the service logs - no bearing issues. So I'd say that there's no reason to bother changing to the old style setup. The new parts are available from a dealer or from HammondOrganCo.com:

Shaft Extension Assembly - part number 520-137836

Bearing, plastic - part number 517-137264

Grommet, shoulder, neoprene - part number 543-137255

Ok, let's try another approach. Has anyone replaced the late model shafts which have nylon parts (grommets in place of bearings) with the more standard shafts and roller style bearings? In thinking this through, the toughest modification seems to be routing out the bottom of the cabinet for the bearing mount. Anything else?

Thanks to all for your wisdom and assistance.

Are you sure that that the spring is really needed? I've had the rotor out of a 122A (which has the same parts), and I don't remember any disassembly or assembly issues - or if the spring was there.

While cleaning a recently acquired Leslie 330, I removed the lower Rotor shaft by pulling it up through the rubber grommets. The problem is the lower Rotor was stuck in place by a mini shaft that is held in place by a spring. When, I tipped the cabinet on its side, the mini shaft came out.

There is a tension spring that extends from the Shaft Pulley Assembly (part 7) into the hollow Shaft Extension Assembly (part 9). The problem is how to align the spring so that it fits into the extension? The spring flexes off to the side when lowering the shaft.



Any experts out there, thanks in advance for your guidance.
