Sprocket, red dust and refurb....

It's very interesting that the torque spec has been increased to what I believed was more appropriate some years ago. :thumbup: I note that a hardened washer is not shown in the parts illustration - curiously. What markings are on the head of the bolt h0gr1der?


Edit: The parts list for the V2 shows a bolt 65mm long with a hard washer that's about 5mm thick.

The OEM bolt has thread locker imbedded in the thread.

I ask because I need to know which Loctite in the event I buy a replacement bolt that is not OEM. I have a screw supplier in my neighborhood that carries a huge variety. I'll wager his prices are a lot less that BRP's.

It's unlikely that your supplier will have a flange-head bolt - you would have to fit a hardened washer to it and it needs to be 10.9 grade and 60 or 65mm long depending on the washer thickness. But for $12 why bother?

Mr. RICZ,

The flange on the OEM new style bolt head is very large compared to normal flange head bolts. It has yellow encapsulated thread locker already on the threads and costs 10.49 each from Cheap Cycle Parts. Arrives in about a week to a week and a half.

... I bought a new bolt for my inspection, it's a flange head M12 X 60 DIN 6921 S Grip. Built in washer.

The standard thread pitch for an M12 bolt is 1.75mm, I didn't measure mine because it didn't occur to me but I'm sure it was a much finer pitch. How'd you like to measure it for us all Mr, h0gr1der?

.My 2019 RTL manual has the torque at 111 Ft/Lb ±4 Ft/Lb. That's 150 n ±5 N for our friends across the way.

That's good info, it puts my guess right on the button. Thanks for looking it up.


On the locktite thing, I use general purpose thread lock compound and it's purple in colour.

Thank you Freddy and hogr1der for enlightening me about the OEM bolt. I will definitely go that route. I have never torn into that area, and assumed the bolt was a standard item - apparently it's not.
If I were to go through my dealer, is the price the mentioned $10.49 there too?

 

[Freddy]

Should be close to that but for a buck or 2, who cares?

 

[RICZ]

So I went down to the garage and removed the front sprocket cover and 1. I see what y'all were talking about that bolt with the ginormous flange. Yeah, that's not found at Ace Hardware. 2. The bolt was tight and everything was clean. 3. I will be checking that often. 4. Thanks all for putting up with my dumb questions.

Just thought I'd bring this to the top for an update.

Rechecked the bolt yesterday after a little over 5000 miles since the repair. Bolt nice and tight and no sign of any movement so it would seem that tightening to 110lbs/ft (ish) has done the trick.

Did you reassemble with lubricant on the splines or assemble dry?
