Busy busy....

Is that the same composit they used to make the hiem joints...?? Soon you will have some high mile ones to test...:thumbup:

Naaahh, I'm done testing. It is what it is.

Let me get this correct------ The BRP pulley uses ONE bearing not two??????? I'll be getting Doc's system ----- a much better design.


Kaos


NEVER MIND------ I looked a one of doc's other videos and see that there is only one bearing !!!!!!! BRP cheaped out.

Doc's new pulley uses two sealed bearings inside the belt pulley.

Better than BRP

Yes, I think it's a much better design than the single smaller bearing that BRP uses.

I've already ordered mine from Doc, and am awaiting it's arrival... :thumbup:

I installed mine on Saturday night, I had the BRP idler pulley set up with Doc's adapter, and decided to just remove the BRP part first and not mess with the adapter. I wasn't happy with the final result, and took the arm and adapter off to get the arm mounted better. (less movement, no binding). So I mounted the are and pulley to the adapter bracket on the workbench, and tightened the pivot bolt until I had it as tight as I could get it with out binding the arm, with the spring installed but not in the slot on the arm. Then I mounted that assembly to my RT and got the pulley with even spacing on each side of the belt. THEN I put the spring into the slot. I haven't touched it since. Good luck with your assembly, you'll like the finished product, I think it is actually a bit smoother than the BRP one and adapter.

Does anyone have pictures of what the proper alignment of the roller and the belt should look like? :dontknow:

Bob, we have been splitting the difference on the belt. It will overhang about 1/8" on either side. Just make sure you have pulled in straight since the belt likes to walk backing up. Jacking the wheel up and spinning it forward by hand should give you a good idea that the alignment is correct. Or, you can spin it around the block.

Thanks, Doc! :thumbup:
(I sometimes have trouble figuring out how something should look... pps

Do you have any ideas how long these will last before you have to replace it?
What is the most miles anyone out there has on the BRP or Doc's tensioner?
When we go on a trip and put 5-6 thousand miles on in two weeks, I don't want to have to think about the bearings on the tensioner going out. Is that going to be a problems in anyone's experience or opinion?


Thanks

Good question, I don't know the answer but would think that if there was a failure BRP would be required to accept responsibility and make the necessary repairs, Not sure how that would work on After Market Pulleys, Anyone Know???

Ref :- if there was a failure BRP would be required to accept responsibility and make the necessary repairs,

At present this would only be for the f3 models as the BRP one was only made for those models
All those currently being fitted to RT models are using an adapter bracket made by Doc Humphreys, or other self made ones
Having fitted one myself using Doc adapter bracket I accept the risk knowing the time, effort & testing he has done with it and by him making adjustments and upgrades to it before releasing it
BRP may or may not make one specifically for thr RT
The RT has been out far longer than the f3 models yet BRP designed one for the f3 first so who knows if and when the will make one, rather than wait I went with Doc's one
There are other options for tensioners available but for me Doc's was easy to fit, once fitted it should not require any further adjustments and was at a price I could afford

I like the idea that he uses two, larger bearings in his setup: This can't help but make it last longer. :thumbup:

I agree! I also understand that if there was a failure on a trip, it would be easy enough to take the pulley or wheel off and run without it for the rest of the trip.

A couple of 10mm wrenches could easily remove it. Not going to need to though. These are rated for roller blades. And, the way they are secured with no side pressure, I don't expect none of them to ever wear out. Time will tell.

Doc,
Do you have any idea as to when you'll start shipping these new complete kits out? :dontknow:
Will we be getting a tracking number?
Thanks!

Yes..........and Yes. Anything else???? :dontknow::dontknow::dontknow::roflblack::roflblack::roflblack::thumbup::thumbup::thumbup:

Actually, I just finished your kit. It will go out today and you will be given tracking. Also, will need a signature on your end. (No box scarfs off the porch that way)

 

[Bob Denman]

Just one more thing... :roflblack:

Thanks!
