Roller upgrade for Doc Humphries Vibration Damper

[eddieshep999]

A friend of mine wanted to renew his roller on Doc Humphries Vibration Damper
Unfortunately Doc Humphries is no longer trading
He did see if he could fit Lamonster larger roller to it but was advised it wasn’t suitable

He has found a replacement and posted this on our UK Spyder Website Facebook page
As this information may be useful to others with Doc Humphries Vibration Damper he has given me permission to post the details here :-

DRIVE BEŁT ROLLER UPGRADE

For information of Paul Phillips and Duncan Parker.......Re Eddie Sheppard post last week regarding belt tensioner roller upgrade ...

I have today fitted the Dunlop R15/18 larger roller to my Doc Humphries tensioner arm.

Had to drill out the 6mm hole to 10mm but the end result is a decent two bearing roller with larger diameter and good coverage of the belt.....well up to the job 👍

Is that new roller hitting the Switch in the back now? Its in your third picture.

I posted this of behalf of a friend so I had passed the question on to him
But knowing how experienced he is on working on his RT
I reckon he would ensured there is no clearance issues

I have his response now see:-

Eddie Sheppard Polenty of clearence ALL around and for full
swing of the arm. The only close part was the roller bolt, but the Doc Humps was just as close. I ground a bit away when I fitted Docs arm. This pic is better angle 👍🕷

Is this item available in the USA??? Shipping costs more than the part. I looked around and couldn't find a US supplier but I'll keep at it.

Did he actually drill out the ID of the bearings from 6mm to 10mm? I don't see how that is possible. The bearing should be hard and it is too much difference in size.

[trikermutha]

Lovejoy has a compatible roller on amazon

[Snowbelt Spyder]

I interpreted that to mean he drilled out the hole in the arm from 6mm to 10mm, to accept a larger diameter bolt.

Dah! Yes, I see it now. Thanks.

[Snowbelt Spyder]

Dah! Yes, I see it now. Thanks.

Which begs the question - is that all it will take to make Lamonster's roller work - to drill out the hole to fit his bolt?

Watching This thread.

Yes you are correct it was the arm that was drilled out
There were no mods done to the roller
I think the roller takes a 10mm bolt I believe Lamonster roller takes a 6mm bolt
He did ask if he could Lamonster’s roller to the arm but was advised it was not suitable

[eddieshep999]

I have found the dimensions of the roller if it helps as he purchased his from e bay UK site and you may find in your country with the same dimensions

I don't use a vibration dampener. But if I did, I'd try to go with as big a roller as I could get. Reducing RPM would go a long way towards longevity and a problem free device. I kind of liked the idea of adding O-Rings to the roller. Does anyone know how that approach worked? Not sure if O-Rings could stand up to the abuse. But there are a good number of silicone compounds making for very tough O-Rings out there. Swapping out O-Rings, if necessary, might be less expensive than the complete roller. And would add just a bit more diameter reducing RPM as well.

This brings up an interesting question. What is the RPM that these rollers are turning on the drive belt? The belt speed would be the same for every application. But roller speed is greatly affected by diameter.

I had Docs damper on my other 2013 RT with the orings. The worked fine, I put new orings on each season and that was about 10,000 miles average. definitely got rid of the loud whining of the ribbed belt on the 13"s. Now the 2013 RT Limited I now have. i used the BRP tensioner with Lamonsters roller. I has a quiet whine, but not that noticeable. Very good combination.

Very interesting calculator! Does not take into consideration all variables. But it is a very good reference point. Thanks!

[T.P.]

We need to figure out how to fit Lamonsters roller assembly to Docs assembly, Because the blue and the white roller are only rated to 8000 rpm and we exceed that, those won't work long.
The bearings in the Lamonster roller are rated to 12,000 rpm and looks like our best bet.

[AY4B]

If you still have a "Roadster Renovation Belt tensioner installed on your Spyder, I would advise you remove it and put a different brand completely. His failed on me last fall and I had to replace my belt because it was damaged very badly. I was lucky to get home from the SITH Rally.

The Lamonster brand is Molibus and the side shield stamp is 6202RS greased mine not much in there.

A word about Sealed Bearings: Grease as we all know is used to lubricate Sealed Bearings. These bearings are not "packed" with grease like open bearings (like in a tapered wheel bearing). There is only enough grease to provide lubrication. The seals keep the grease in and the dirt out. Grease also acts as on insulator. If a high speed Sealed Bearing has too much grease, it will overheat. The small amount of grease is by design.

Another issue is mixing greases. If you add more grease to a Sealed Bearing without cleaning out the original grease completely, you may induce a failure. The carrier compounds in greases are not always compatible. When they mix they may react by dissolving each other or drying and turning into a concrete-like substance.

More is not always better.

[RICZ]

I shoulda sed extricate the old grease, clean and repack, but not full - allow room for expansion. I did this when I had a machine repair biz, but the bearings I was dealing with revolved much slower than those on the belt tensioner. So it might be my idea does not apply after all.

Good post Grandpot, and talking about to much grease and overheating I've seen the seals blowout under that condition, and then it's just a matter of time.

I've always been a fan of SKF bearings, and the good news for us Spyder owners with the belt tensioner is that the SKF bearing is rated for 28,000 RPM :thumbup:, specs at the Grainger link below. I'll be ordering the SKF tonight just because.

The other thing to beware of with bearings is that the ChiComs have a lot of crap out there falsely branded SKF, NTN, etc. so if you see a price that looks to good to be true, it probably is made out of chinesium.

What I'd like to know is: Why doesn't my 2014 RTL even have a tension/damper roller?? I have no serious vibrations or noises coming from the belt; but since I bought it used with only 6,500 miles

ChicagoSpyder does that bearing fit inside the lamonster roller, and if so does is it just pressed in?

The damper units are strictly an add-on. Some folks have their belts adjusted right in the sweet spot, others never can seem to get there, so the dampers help.

There are so many variables with this issue. Some people don't really care if their belt vibrates. It drives others crazy. Some vibrate a little. Some vibrate a lot. For some, the vibration resides at a speed that they run all of the time. Others get vibration at a speed that they just motor through on the way to their usually speed.

Some have adjusted belt tension and gotten good results. Others never seem to be able to get vibration reduced to their satisfaction. It's easier to install a dampener than to trial-and-error belt tension hoping to get lucky.

So, it really depends. It's not a 'One solution fits all' situation. The real issue here is why so many dampeners fail. And when they do they usually take your $300.00+ (parts only, installation not included) drive belt with it. The dampeners work great at reducing or eliminating vibration, for the most part. Getting a reliable one has been somewhat of an issue. With the BRP offering being, by far, the worst of the bunch, it seems.

[ChicagoSpyder]

ChicagoSpyder does that bearing fit inside the lamonster roller, and if so does is it just pressed in?

It's the same dimensions as the Lamonster bearing, and yes pressed in. I like SKF bearings but ant quality bearing such as NTN, or Timken will suffice as long as it has an RPM rating that meets or exceeds the RPM's the bearing will be subject too.

I would like to add any roller bearing used in the tensioner should be checked for rolling smoothness at the 4000 mile mark, and IMO replaced at the 8-10K mark as it's just cheap insurance to keep Mr. Murphy away.

If anyone really wants to save money they can pull the bearing out, open the seals, flush out all the old grease and replace with new grease.....but it's been my own experience that grease seals don't ever seal and hold like they did when new, so for the price of a couple of drinks I just replace the bearings in my somewhat wisened days :roflblack:

[irvin48]

after all the running around finding the stuff you need and doing the mods
you could just buy the lamonster setup with a MUCH bigger roller. works very well.

Could be the dealer put it on for his own reasons. He may have had belt vibration issues with past owners and figured this would be a way to avoid them in the future.:dontknow:

I received my new belt tensioner from Lamonster yesterday . I check it and it does have the 6202 RS bearings. If I understand it these bearings are good for 12000 RPM. I don't ride that hard. Very seldom ride over 80 mile an hour. Interstate 70 to 75 mph.

Same here, my girlfriend and I purchased new 2018 F3T’s from separate dealers and they both came with the BRP tensioner. I thought BRP had the tension issue resolved when I test drove them. I was performing some mods later on and to my surprise discovered the tensioners on each Spyder. I contacted the dealers and they didn’t install them, so it appears they came from the factory that way. I replaced the rollers right away with the Lamonster roller.

I guess starting in 2018 BRP installed the tensioner on the Spyders with the 89 tooth rear sprocket which would be the F3T and F3S. The only Spyder for year 2019 that has the 89 tooth rear sprocket is the F3S. I’m not sure on the 2020 F3 models.

The long and short of this whole post is that, just like having to change your oil, if you have one of these units on your bike you should defiantly be checking it at the same time for wear! It has bearings and spins like hell down there, and bearings do not last for ever, no matter who's unit you have. Myself, when you roll down the road you can feel every thing on the road, a little vibration for the belt I think I can live with so far! Now if it vibrated as bad as my fathers old electo glides use to, right up threw the foot pegs, I would have a problem with that!!:2thumbs: Good Luck guy's, and gal's with your dampeners!

Looks like upgraded bearings will be a 10k mile maintenance item. Didn't really look, are their two sets of bearings in the Lamonster roller?

Keep it stupid, simple! How many miles did you ride with out one and did you really have a bad vibration or was you just keeping up with the jones? Possibly just a belt adjustment could make your ride as smooth as you have it now, and it would break down when you don't expect it! There's no problem with any of them, you just have to check them to see if they need to be changed out!!!! Bearings do not last for ever, they have to be checked! Think about every thing that little wheel down there go's threw and what it's doing! If I had one on my bike it would be checked as much as the oil!

I miss understood you. I had a 2015 RT and had one of Dr's tensioner on it and had about 25,000 miles on it with no problem. I took it off and was going to install it on my 2019 RT. l did notice the roller was showing wear. The bearing seemed okay.. I decided to purchase the one from Lamonster with the new roller. I do have my belt about perfect for adjustment and did not think I had any vibration. After installing the new tensioner I do feel that it is a little smoother. I though if there was a problem I was just going to remove it but I am not going to. I will check it more often. Thanks for coming back to me.

Reviving this thread for clarification. I have about 7K miles on my Lamonster roller, of which about 3K miles are 75+ mph freeway speeds from a couple of trips. Should my roller should be good for another season, or would a $50 expenditure for a new one be prudent? Thoughts ?

[Grandpot]

I replaced the roller with a timing belt pulley from a 2005 Hyundai Santa Fe. The logic being the pulley is a larger diameter, it will turn slower than the original. It has a smooth, wide surface so it doesn't whine. It has a large, high quality bearing that is designed to operate in a harsh environment. Been running it for 8,000 miles with no issues.

I don't have an exact part number. Just order a timing belt pulley for a 2005 Hyundai Santa Fe with a 2.7 Liter engine. I used the one that came off my car when I changed the timing belt and pulley. My used pulley was in very good shape. The hole in the center of the pulley is larger than the screw diameter, so I added a couple of flat washers and a lock washer to hold it in place. If my memory is correct, the original screw is M6 and the hole in the pulley is 8 mm. My plan was to try it out and come back later to put in a larger screw and drill out the damper arm for the screw. It's been working so well I just didn't get around to it. I'll do it this fall. You will also have to use a different length screw and stack up some flat washers as a spacer. Sorry I don't have pictures or more written detail like I usually do, but this is not a completed project. It isn't plug and play, but if you have some basic mechanical skills, you can do it.

I don't use a vibration dampener. But if I did, I'd try to go with as big a roller as I could get. Reducing RPM would go a long way towards longevity and a problem free device. I kind of liked the idea of adding O-Rings to the roller. Does anyone know how that approach worked? Not sure if O-Rings could stand up to the abuse. But there are a good number of silicone compounds making for very tough O-Rings out there. Swapping out O-Rings, if necessary, might be less expensive than the complete roller. And would add just a bit more diameter reducing RPM as well.

Instead of o-ring, I used a piece of a bike tube on top of the brp tensioner roller. Glued over the sanded (and scratched with my dremmel) with extra strong contact glue. Still holding great after a few thousands km. Ribbed belt quiet, no noise what so ever.
(Tube size 27 x 1-1/4 .)

What no comment on this item i installed?

That roller has a smallish diameter. Like the one I have (Doc's) I'm looking to replace the roller with a larger one with better bearings. Lamonsters kit has a larger roller---- I think it's better. Besides the slingmods is out of stock.

I have a couple items made by that company, and they are very nice. They also offer 1st rate service. I'm guessing the reason you're not getting any replies is that their is no real info on the roller itself. They are showing available at the MFR's site. They are very helpful, email/call them for info.

Yes it does have the smaller roller plus i will be exchanging it with the bigger roller from Lamonsters kit. Plus i don't want to destroy a belt.

Look at this one...2 year warranty on roller & bearings...Plus he's a sponsor here...

I have Doc's idler on my 2014 RT and it's working fine after about 12K miles. It's pretty easy to check the roller without removing any plastic. You can reach up to push it away from the belt and spin the roller with your other hand. Any looseness or noise of a failing bearing can be heard or felt. I will continue to use it and just check on the condition occasionally.

I am running the one from SmoothSpyder and it currently has 50k miles on it and is still just fine. Much better made unit than the flimsy design BRP came up with.
