• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

F3 Front Sprocket Inspection

I drove it to a dealer and found that it was closed due to Presidents day. I did however check the torque before I left and it was way under the 92 pounds. I torqued it to 92 and went. It should be OK till the next chance I get to drive it down there.

How many miles???
 
How many miles???

Its a 54 mile trip one way so double that. My wife warned me to call them to verify tat they were open on Presidents day and I forgot after started getting ready to make the trip in upper 30 degree temps. Ill drive it again tomorrow but may have to ride in some rain.
 
After seeing that the nut was not torqued and not even a thread lock. I saw that what I need to do in the future instead of checking for red dust, I need to check the torque about every 5-8k miles. If it has broken its lock, I need to remove it and add more thread lock and re torque. Ill ask Chad at Texas Adventure powersports if this is a better way to check than just waiting for visible red dust.
 
I discovered the red dust on my 2015 F-3 sport after 13,000 miles two weeks ago. I ordered the pulley sprocket, bolt, washer, off of cheap cycle parts.com...ordered the loc-tite spline grease from amazon. My mechanc installed it and torqued it at 92 ft. pounds...I also installed a new kumho rear tire...as a safety precaution im going to replace the pulley, bolt and washer every two years...and also inspect the pulley at every oil change (every 5000 miles). its not expensive to replace it..as long as you catch it before it fails. This is the best way to do it...my mechanic agreed.
 
Just got back from getting my Spyder sprocket replaced. They gave me the old sprocket. It was pretty worn and rusty. He said the part number is now different. That means they finally have upgraded the sprocket.

Sorry but that is not correct. Part number 705502134 is still current for all F3 2015 to 2019 and is the same part that was installed on my very early 2015 F3 (unit number 103). There is no upgraded sprocket nor is there any problem with the sprocket. Its the installation of the sprocket that is causing the issues.

A local rider that required needing his front pulley replaced informed me that Can Am / BRP is not recommending Loctite in the TST and provided a copy of that info. Seems some have used Loctite, ours was lubed when assembled new and has no wear. Just sharing info, not saying what is correct or better.

I am just relaying what they said. I asked him what improvements and he did not know. I just assume that the only improvement they could make was the type of steel but I dont know. I do trust this particular dealers service and Chad who does the work. I could have gone to my local dealer in Greenville but do not trust them. I had to arrange transportation from and to Richardson in some pretty nasty weather in the middle of rush hour in Dallas.

What I will do is go take a pic of the new part and post it to compare the numbers stamped on the outside.

I did not use the loctite 648 sealant...I used the BRP recommended moly lube spline paste so it will be easier to remove if/when it needs to replaced in the future...

I just went to remove the cover and you are right, it is the same part number. 705502131, but neither one had your number of 705502134

You mentioned and posted you ordered Loctite, now you say you used moly lube that BRP recommends, pretty certain the BRP stuff is not moly lube. As longas you are happy, all the best with it.
 
He did say that he used Loctite 648 on the shaft and bolt.


Well, the bolt will not backoff or fall out...

FWIW, most timeswhen using Loctite products with a high strength rating, you must use a lot of heat to soften the bond. I would believe 648 on threads is a very strong bond and myself would be cautious when removing that bolt, fearing it will snap off inside the shaft, but maybe not.

Yes I did tell him before to just use regular blue on the bolt. I commented when he said he used 648 that it will be hard to get off, he said he can get it off. Im just hoping that with the 648, the bolt will not back off like the first one did. Im thinking that as long as it keeps its torque, it will hold with the 648 on both. The description on the 648 also says it prevents rust.
What ill do is make a note on the owners manual of the sprocket falure, the mileage and that 648 was used on both the bolt and sprocket. Use heat to remove.
If there is a next time, I'm thinking they will have to replace the shaft also.

Would you happen to have the TST number from your posted picture ??
 
The part number I gave is the replacement part number from the order system in a retail box. The part number stamped on the pulley is the assembly part number shipped in bulk to the factory. If you look up the part in the BRP parts system, you will get the part number I gave you above.
