I blew the belt on my 6HP YammerHammer blower, meaning I had to push/pull the darn thing home into the garage. It has (previously) eaten 2 goodsized chunks of newspaper/ads burried in the snow - but it wasn't the auger belt that let go - it was the drive belt to the Hydro unit. (But I will replace them both while itr is apart!!!)
After a LOT of searching/calling I found a current part number and ordered the OEM belts. It was a bit of a scare, as the first prices that came up were $112 and $55, but after they got through the supercession list the current parts are only $51.73 and $24.57 (in Canadian dollars)
Also found the measurements and they are a A29 for the Hydro and a B36 for the auger.( or 4L310 and 5L390) What would be the best aftermarket belt to use on this unit in the future that is generally available and will handle the abuse a track-Drive snow blower can dish out?? Having backside idlers makes some less advisable. Is a cog belt an advantage or disadvantahe here? I used a cog belt on my old friction drive blower and it worked well in the snow-filled semi-open drive area - limitting the slippage to the rubber friction drive wheel.
Looking at the Timken (Carlisle) NON cogged listing there is the Super II and the Aramax. The super II is their "problem solver" HD belt and is a "raw edge" belt, while the ARAMAX is a kevlar wrapped belt designed for lawn equipment.
Any belt experts out there who can ring in on this??
