Bought a Super XL-925 as a father’s day gift for my pops ($190 from a man who inherited the saw from his stepfather). Cleaned it up, replaced the starter rope and a clutch plate screw, then filled it up with Rec-90 + Amsoil Saber and some Amsoil bar oil.
We went to tune it and the saw started right up, tearing through a 20” log and putting every saw we’d ever used to shame, but the chain just wouldn’t keep still on idle no matter what we did to the low speed adjustment.
Come to find out, a portion of clutch material had flaked off, lodging itself between the shoe and drum. Not only that, but another shoe’s lining had also begun delaminating. If not for the deterioration, the clutch would have probably had a couple years of occasional service left in it, with a little over 1/16th remaining. This is my first post here, so I’ll post some pictures later, once I figure out how to do so.
NOS clutch shoes aren’t growing on trees, and age will inevitably rot what’s left in store. Because of this, I’ve decided to embark on a (potentially) fools errand of relining the 3 shoes myself. McMaster Carr has some high friction brake & clutch material available in sheets of 7 1/2” x 7 1/2” at 1/8th inch thick for about $40 after shipping and tax. Plan is to secure that to the shoe using a homemade jig once I order some Anabond 230 off Ebay for another $40.
After cutting the material to size, applying the adhesive, clamping it all together at roughly 100psi of pressure, and tossing everything in a toaster oven @374f for an hour… we’ll see how it holds up. Best case scenario, I’ll likely never have to worry about clutch wear on any of our saws again. Worst case, I’ll tally up the total cost of my hospital bill. Either way, I’ll report back to let y’all know.
