just one more win for the mamba max 5700

the war must go on though

my tools wouldn't have saved me this time, but my extra spur gear would...looks like I need to get more of them.
Vintage--
I had this same thing happen to me last night with mine-- Upon closer inspection, on the bench, I found that the slipper had gotten so hot that it heated up the mounting screws, melting the slots in the spur gear, & warping it out of shape! The warping then threw the teeth out of alignment, causing them to strip.
The back-side of the spur gear was melted smooth where it contacted the slipper & the slipper disc also had melted plastic stuck to it--
have you had this issue reoccur?
I was pondering some sort of heat sink / cooling fins for the slipper assembly, but it seems like a lot of unnecessary work when compared to upgrading to the latest slipper design.
I now see the wisdom of the new (B4 T4) slipper system-- it allows for much better cooling of the slipper & keeps the heat off the spur gear. Looks like I'm going to be upgrading further!
