Does the dealers have the bolt. Cheap cycle parts has it but shipping and tax comes to more than the cost of the bolt.

Do not use Moly Grease. Use Moly Paste. As for the bolt, the reason for not reusing it is on account of the pre applied threadlocker which is considered one time use. The bolts are not torque to yield so structurally they are fine. Be aware that on line suppliers are still selling the old style bolt / washer setup. Last week on the FB group a person showed his recently replaced bolt that he purchased on line and it was the older type.
I do not have my Spyder maintenance logs handy. Is that the part number for the large flange bolt or the original bolt with small flange. I ask since last week a person posted that they ordered from Cheap Cycle Parts and was sent the old style vs the later upgraded style.
PMK what is the difference between moly paste and moly grease? TIA.[
....... When I mentioned why they should, the reply was, we've never seen a spline failure. That's hard to believe.
....... They reported no problem at 14000km, and they also told me they had never seen a spline failure. Why wouldn't I believe them ?
The two styles have different part numbers. The parts catalogs for 2014 and 15 still show the older bolt and washer. Nothing wrong with the old one as long as you use it with the washer. You can use the new style with the large flange on any of them as well.
Its likely that Cheap Cycle Parts sent the part number ordered. The PN has not been superseded and both are still available.
The part number for the flange bolt is 705502292. Just ordered mine from my dealer who doesn't keep at least one in stock. When I mentioned why they should, the reply was, we've never seen a spline failure. That's hard to believe.
I guess we will both find out. I ordered by phone from my dealer and the parts gal looked it up. Fingers crossed.I was told the part number is 250001017 That is what I just ordered. Is it wrong?
To the original poster... If your sprocket is only lightly worn, ie. after cleaning up is slips back onto the shaft nicely with little play then imho it's better to use it rather than fit a replacement. The reason is that the contact surface of the sprocket against the flange of the shaft is small (marginal imo and part of the original issue.). These contact surfaces will be worn because of their movement against each other but on the plus side they are worn into each other and have good contact so will fit well upon tightening.
If using a new sprocket the contact surface with the shaft flange will be smaller because the slightly worn part of the shaft will not make contact with the new sprocket. The new contact area will be smaller diameter and consequently have less surface area to carry the end load. I'm sure BRP have taken this into account because the updated sprocket is machined with a wider contact surface so as to be better usable on a worn shaft and also provide a larger contact area on a new shaft.
Important! Be sure when the sprocket is refitted that the shaft end is sufficiently recessed in the sprocket that the bolt flange cannot come into contact with it when fully tightened.
The output shaft is hardened steel. The sprocket is usually the casualty when you see the red dust.
Too much presumption! The shaft is indeed hardened steel and the sprocket is cast iron.
See the pictures below for the wear on both. You can see the mating lines where both parts are worn together.
I do not see why some are so concerned ,as long as the bolt has loctite put on it .The bolt does nothing but stop the sprocket from sliding off .
