felt washer

[Zagg]

I will post pics tonight. Had to pull the bed off a pickup that I sold. Carbs are VM, the part numbers I referenced we simply meant to help you understand where exactly the felt washer was located. I am assembling the last carb tonight and hopefully mounting them on the plate.

Thats our pont............VMs dont have any felt washers on them..CVs do. 3 screws holding the tops on the slide towers or 4??

I've got the same bike, and I discovered mine the same way you did. I think I'll try to make my own.

He has VM carbs.
You're talking about CVs.

Oh, darn. Didn't realize.

The carb mounting plate


The eyelets on the plate for the throttle shaft...


There is metal cup ring that is held in very lightly with the punches around the eyelet edge. You can see in this pic the brass bushing inside and the metal cup outside held in by the punches.


In that channel created by the two different metals is (was) a felt washer that looks like this...

[Zagg]

While working on one end the metal cupped washer fell out so you can see the brass bushing inside better....

Not seen them before on any ive had. Just grease the shaft and it will be lubed where it passes thu the eyelets on the plate. Not a critical thing in my opinion.

I bought two different squares of felt from a local craft store to attempt to cut out new one. Not happy about attempting this half assed repair, but a couple were torn and blew out while cleaning so I was stuck either way, but I would rather have just replaced with an exact match rather than cutting one.

Oh yeah, the scratches on the brass are from me digging around. One of the rings came apart and the rest was stuck so I had to dig it out. It was before I figured out the cupped washers just popped out.

You guys have any experience with these things?

That's helpful, thank you. I don't think I would have noticed them if one hadn't blown out in pieces (it seemed like it just came outta nowhere). They are easy to miss because they are black on the inside from grease, grime, etc. I should have taken a pic while they were in. They did not stick out at all. They look like a shadow until you dig in there.

Never dipped or had any thoughts about taking a rack plate apart myself. I ungang them and dip the carbs and use a little spray and a brush to get the old crusty crap off and leave it at that. Grease the shaft as the manual states and reassemble them. Maybe thats why i havent ever seen the washers......Duh!!!!

Yeah, well, I am a half-asser by nature so my attempt at being thorough was to clean the plate with a brush and some degreaser... That's what I get for being thorough. I'm also trying to cultivate a "one thing at a time" process so I don't end up with different components from different areas of the bike all dismantled with limited funds to rebuild or replace.

I need to stop watching frame up restos and sit back down on my bucket for a chair in my storage unit shop with no heat and no money for parts and just get it back together. Unfortunately my passion for getting the bike together and running and riding far exceeds the funds necessary to do so and I end up working with what I have that I don't have to buy.... I have a couple wire brushes and some marine clean sitting around so I went to work just to feel like I was accomplishing something without dismantling another part that I couldn't afford to rebuild.

Congrats Zagg. You may have actually come up with an original topic not yet covered multiple times in this forum. Felt washers; whod'a thunk. Good work in being thorough. Cheers!

I'll be tearing my carbs down over the winter and will take a look in there, maybe I do have them!

This felt pad is nothing more than an oil store for the section of shaft that goes through the bush adjacent to it. It's not a seal, just a lube aid. Felt oil pads were (and still are) commonly used in industry in various applications. Kind of amusing that a tech that's many centuries old (think watermills) is still being used.

Maybe his PO was a watermill worker.
