Title: Clutch issues
Post by: oldskool on September 12, 2022, 06:40:10 PM
I had a stud pull from basket. I replaced it and I can't get the clutch to stop dragging. It's never dragged before. I tried everyday possible to adjust it over and over. I tried turning adjustment screw in till the rod was 1/2 inch from starter. I tried turning adj. Screw in till lightly seated and backed off a 1/4. I pulled the plates out which are brand new and noticed one dog in basket I loose on one end. Could this make it drag ? Also should these new fibers be soaked first? What's your adj method ? I may have a couple baskets laying around  I'll have to look for them.

I run the big fix kit with clutch tamer the black nylon with circlips . Did you replace the pin or complete assemble ? I set up a dial guage and check run out. I have seen .005" on after market hubs. What plates you running? Is it converted to wet clutch?  Your adjustment sonds good.

Do the clutch plates move smoothly on the studs after you replaced the broken one,not moving smoothly could be your dragging issue

If the studs are grooved from the discs they can be catchy and don't slid as they should to release.

Thanks guys.I believe that they're Alto. They're green. I don't think they're binding on studs. I will check them out tomorrow

Too much grease on the rollers will end up on the plates. Some plates work better than others. I like Drag Specs DS-223735 and will get some for my Shovel once they become available again next month.

Yes it does ...just had to clean mine the other day because it was dragging from build up

Ok so I pulled the plates cleaned everything.  Checked studs and drilled the plate holes so ik they're not to tight on studs. Went through adjustments. Still dragging.

Did you check for bent studs?
Title: Re: Clutch issues
Post by: oldskool on September 19, 2022, 07:14:02 PM
I did. The plates seemed to be somewhat tight rt at the start going on the studs then slid on easy.i did drill holes in plates a little bit so there weren't tight going on.This clutch has always worked great never had any drag at all till I swapped out the 1 stud and put in these new fiber disc's.

Put the old disks in and try it.

Adjust the arm that the cable hooks to with the center bolt of clutch. Position of arm will let clutch drag if not right.

Clutch disengaged (lever at bars pulled) do you mean ?
Title: Re: Clutch issues
Post by: bump on September 20, 2022, 09:09:10 AM
No the lever on trans where the cable connects. The center bolt for clutch push rod will let you set where the lever sets. turn center bolt will move lever front or back. The manual tells how to set lever in position.

i found if you go by the book you will run out of cable adjustment thread and wont get propper hand lever adjustment

I am not aware of a Specific HD Part # for the Rivets you are referring to.  Over the years I have had to replace Rivets on a few various Older Bikes.  I was able to find them on the large online Retailer that starts with "E", and thru a Local Indy that had them in His Shop for His own repair purposes.
Should You decide to repair the Rivet(s) Yourself...You may also need a Specialty Tool to properly set and peen the end of them.  Unless You may already have the Tool, or make something up.
If You should have a decent Indy, or maybe even an HD Dealer in Your area...I think that I would take the Shell to them and see what they say, and if they can fix the problem  by replacing the Rivet(s).
It may be a lot less aggravation and hassle...and possibly cheaper and quicker.
I don't know if the missing Rivet is Your problem...but I don't think it is helping.
I would also have a concern about if one Rivet is broken, or gone...the rest of them may follow suit.
But that's Me.
Good Luck!

The old trick was to weld them only the threaded studs.

     I never understood the backing off the pressure plate adjustment screw by 1/4 turn. Think about what happens to the clutch push rod when you go to adjust for lever free play. It gets pushed right back over toward that adjustment screw.
     Have you viewed how your pressure plate releases when you haul in the clutch? Does it release evenly all the way around or does it tip to one side?

Just for clarification purposes, and nobody gets confused and is scratching their head...there was a post by the OP stating that He felt there was an issue with the Rivet(s) on the clutch shell, just above My response.
That post has since gone elsewhere.

I have seen a few pulled when there was only shovel running the roads. We'll the old days. I aways welded for security.

.. yes you are correct.  My intial thought that one of the rivets was gone and I think that block may have caused the plates not being able to move freely.. It's been awhile I started to put it back together today. Question to soak or not soak the new fiber clutch discs. I just got Red Alto's
Title: Re: Clutch issues
Post by: billbuilds on June 01, 2023, 03:47:55 AM
     Yes, soak them in what ever you plan on using in the primary. How much slop is there between the shell and the hub at the rollers when clutch is hauled in? I saw a guy replace his old rollers and roller cage and it made a world of difference. This may be where you are getting your drag.

I like the full length rollers and ditch the cage

     Generally speaking, how much honing of the clutch shell bearing surface have you found is required to make those fit?

I have never found need for honing to make the long rollers fit.
Title: Re: Clutch issues
Post by: SP33DY on June 05, 2023, 09:15:02 AM
At least one of the suppliers of the long rollers used to send them out with one extra roller, just in case. It normally takes 52 rollers, and there is 53 in the package.

Good to go y'all.  I swapped out the old hub for a new one. No drag. Clutch work great. I need a new primary gasket as it's leaking oil from chain oiler.As this is a Dry clutch. Seems a little excessive. I don't want the pri.ary to fill up. It's never leaked like this before. But it seems if I'm leaking  that much oil then my oil level is going g down also.

So I've been running the shovel clutch is all good now. But now I'm rolling and all the sudden I'll get a miss then the bike gets louder and loses power. Idk if I'm dropping a cylinder possibly. And I noticed a Crack on the coil rt where top bolt is.I pulled it off to look for a part number and I don't see one anywhere.  The bike has a crane hi 4 ignition and the coils is a 3 wire.
Title: Re: Clutch issues
Post by: xlfan on June 29, 2023, 02:20:33 AM
A crack in coil casing is usually a bad sign. Any 3-wire 2.8-3 ohm coil will work with the HI-4.
