Kicker Flapper

Tornado · Jun 23, 2023

My original kicker flip out part is flapping about a fair bit while riding, such that it occasionally makes itself known to my right foot's heel.
It is not the actual lever moving, implying inpending layshaft bearing failure.
Tried adding a washer to the swivel assembly but that just makes it very stiff, nearly impossible to flip out/in when needed.
Is there an easy solution?

Are you missing number 32 a spring washer?

ILLF8ED · Jun 23, 2023

The 850 Mk3 kick lever I’m using has a coil spring and steel ball detent the hold the kick pedal either open or closed.

Original without year is the issue . Previous MK 111 models did not use the detent ball to help it stay in place . Just the spring washer and judicial tightness .
Now if the shaft starts moving about , then you have the known layshaft bearing imminent explosion .

And loctite that nut!!

It's a MKII, sorry about that. I'll check for the spring washer as I don't recall it was there when I tried a regular washer. Quite a bit of play/rocking on the bolt as it is.

Bolt is tight...and does not affect the swivel action as there is a shoulder/standoff in the design.

Ok, no spring washer. Only one I have handy is too thick so the shouldered section ends up below the rotating piece and just makes the top nut seize everything solid. Will live with it guess until I need to place a parts order for other stuff unless this is something to be found at hardware stores?

Substitute a small O-ring lubed with vaseline. Blue loctite on the nut. I forget exact size or thickness, but I think snug around threaded part & not to thick.
Forget how many years ago I did mine.
Cheers

Was just thinking of trying an o-ring....guess fools seldom differ, eh?

AN's image for this spring washer shows it thus (a domed/dished washer):

So pretty specialized...little hope of finding a local source.

There are other types of wavy washers that can be used. Check McMaster-Carr or eBay for small quantities.

last week the morning radio guy was having a contest; guess the name of a city with two clues... so I gave him: A type of washer, and home of 'Cheezies" He nailed it right away as Belleville - I told him I was surprised he knew about the washer - said he worked in a hardware store before radio...

Bass season is now open . Belleville has great bass fishing . I'm taking the Norton there on Wed. with rod on the back , sleeping bag and a container of worms on ice in the saddlebags . It's summer !

Actually my long RGM kicker was getting a bit loose on the pivot (doesn't have detent) so I managed to slip a thin Belleville spring in there.Works a treat.
You guys probably know this but... you can stack Bellevilles two ways:
1. In parallel - so that the top one nests on top of the first - increases the poundage of the spring but not the deflection.
2. In series - so the big (or small) ends go together - increases the deflection but not the poundage.
...of course you can do both too!

Ah ! but did you know

they were
invented in the mid-1800s by industrialist Julian Belleville.
The cone-shaped steel washers can resist high loads in a small space, providing high spring force over a very short distance as well as high-energy storage capacity. Commonly used in industrial valve assemblies, the washers ultimately proved invaluable in warfare, as return springs in large-caliber artillery......Belleville washer designs used by the U.S. military were classified until the 1970s

The belleville spring washer system is now manufactured in full carbon composite and the spring disc system is used for motorcycle suspension components and the like

It is possible to fabricate the later spring and ball combination into an earlier kickstart lever. https://www.accessnorton.com/Norton...do-with-your-commando-today.33718/post-611878. I did this in combination with the Belleville washer.
