When assembling my Horstman HDC-5B (2 disc, whichever model that is…) back on the crank of my KT-100 after re-lubing the bushing, I noticed what I consider to be extreme amounts of free-play — the clutch housing / driver side could be flip-flopped side-to-side by approximately 3/16″ at the exterior rim, enough to notice the chain visibly misaligning. So, my question is:
– How long do the bronze oilite bushings last?
– How do you know when they’re out of spec?
– How much free play should the clutch have on the shaft?
– Is it possible the crank is worn instead of the bushing (or both)
(crank seems fine, no real grooving that I can see or feel.)
I’m considering going to a Patriot or putting on my DXL’s anyhow, but figured I’d ask…I assume I can press in a new oillite bushing and re-test…Thanks,
