520 conversion

[pdxjim]

Doing 520 chain/sprox conversion on my LC.  I would assume it's v. similar to RD350/400 in this regard

Got the 520 front sprocket. Got the standard 4L0 CS spacer and nut. Got a new tab washer.

As I suspected, the CS nut bottoms out on the splines before tightening down on the sprocket.

Looks like I need a washer/spacer on the outside between the sprocket and the tab washer.

Am I correct that "clutch thrust washer" 360-16154 will fit and give the appropriate clearance?

Crude measure as pictured looks to be +/- 1" ID which is what the splines measure.

i think so. mine came with a washer.

On my RD350A  (aircooled), the 520 countershaft sprocket has extra "meat" on the outside, to make up for the difference between 520 and 530.

Try 2 tab washers, It was shared in previous forum.

Def not thick enough.  Needs about 3mm.

Thx for the idea, tho.

This is what I have on both of mine and have used on others that I've built. It's just a shim or I've seen them referred to as a machinery or machine washer. It's .047 thick, OD 1.50 and the ID is 1.01. I just get them at the hardware store. I think you can also get them Tractor Supply. Nothing special at all. Cost about a buck.
