Hey, I'm new to the site but loving all the info I'm finding as I have a mid 80's Bravo Long Track that died in the back 40 with no spark the other day. Plan to drag it home and tackle that this weekend.
Also have a mid 80's Excel III that I've been trying to figure out how to make better for the kids to get around our rather steep property. They are young and I remember when I was a kid my dad would heat up the primary clutch spring and compress it in a vise so the sleds would engage at a really low rpm and pretty much walk up anything. Short of doing that, I cleaned the clutch yesterday with my air compressor and sanded the sheaves of both primary and secondary clutches and that helped it engage quicker and slip a bit less.
My real problem is that the belt seems to long as it's slipping at low/mid range. You can really see it slap up and down when removing the guard and spin the track on a stand. I guess I'll buy a new belt but I was wondering if there's any adjustment that could take up some of this play? The belt measures 1.25" with a tape and that's spec for a new belt but rides about .5" below the top of the secondary clutch and I think it should run flush.
There are no spacers in the secondary clutch so I can't remove them to get the belt running higher and take up some slack. If I loosen the motor mounts could I slide the engine forward a whisker? Does anyone know of a belt that is maybe a 1/16" wider than the stock (828-17641) recomended for this sled? Dimensions for the stock belt are 43 5/16" long by 1 15/16" wide (some sites state 1 1/4" wide)
Thanks for any advice. These sleds have been waiting for my boys to come of age and now that they've got the bug they want to ride!
