One more question and I think I will be done for now! On the front plate of the mounting bracket (that the gearbox bolts to), the l slotted adjustment holes are much wider than the bolt. Mine takes a 3/8 carriage bolt and the slot is nearly twice as wide. So if I use a standard 3/8 washer, it crushes them and bends the bolts. Also, when adjusting the belt, this allows the bracket to slide crooked. Are the slots supposed to be that wide? I was thinking of either making a bushing or a really thick washer that won't bend. |
There are spacers (4) on the Carriage bolts so the plate can slide with the bolts tightened (like if they were shoulder bolts) that way it is a quick attachment/adjustment.
You can adjust/change/install the belt without loosening the carriage bolts.
Just turn the adjustment wing nut.(belt adjusting bolt they call it)
Sounds like yours are missing,--- probably make them up using small piece of pipe, should be 3/8" inside and fit the slots smugly on the O.D and just a tad longer than the plate is thick- 1/4" long.
on cubcadetparts it is #8-- IH 490125-R1
but the Dimensions Are not that critical.
The spacers for the Qa blower gear box mounting plate are:
Outside: .560
Inside : .390
Length .250
a 1/4" pipe nipple comes close to those dimensions, but is on the smallish side.
