Title: A10 Plunger brake pedal return spring
Post by: Drew Back on 19.09. 2014 14:29
Does anyone have a good pic of what this spring looks like and how it goes on the bike??at the rear hub or on the brake pedal shaft I suspect I have the wrong spring or im just an idiot because I cant figure out how it goes .. Its for a 1955 plunger.

Quick pix of my '55 Plunger.
Draganfly sent me the wrong, (possibly swing arm style) spring twice before they sent the correct one.

Looks like a bit is missing or is bent out of shape, Dutch!

I had trouble getting my spring on. In the end, I engaged the pedal end first and used a screwdriver to lever the other end past the frame tube which must have deeply scratched the powder coating!

Yeah Trev, somethin' ain't right, looking at GrayB.'s, it looks like the pedal hook isn't hooked enough or something....for now I actually don't give a rats', one day when I'm bored...

Here's a great tool for pulling springs on. Came across it on a bikejumble. Already came in handy a couple of times. I even managed to pull on the plunger's centre stand spring with it.

Morris, that looks like a very handy 'persuader'

That is a great tool; it enables easy  and safe installation and removal of stand and brake springs in an instant.

I bought mine fro MikesXS.com, for next to nothing.

He has many great value items (tools and japanese bike parts) on this site.

Brian, check out the japanese electrical items, and reflectors, etc.

Thank you so mutch for the pics it makes a lot more sense now I was trying to put it on the rear brake arm..I ran into another snag today with primary cover hitting foot peg mount that seems to be bentup just enough..Those things are tough and dont budge easy shal try to use a torch to bend it down are they supposed to that close to primary cover?

They are tough suckers but you'll be pleased they are when sliding down the road. They do save a lot of damage.DAMHIK. I bent mine back in a large sturdy vice and 5' of water pipe, no heat.
Cheers

I am talking the mount on the frame itself it needs to go down and back about 1/8 but its pretty hard when you have a motor and tranny in the way im using an old fork tube and 5 pound sledge hammer have to get the old lady to help later..

Put the hammer away and find a longer piece of pipe, and make sure the stud/nut are in place....!

Well I got the bike running at last ran into another problem my spring only has 3 turns no way to get it around frame or brake pedal from all pics ive seen looks like B31 spring..Now I have to locate the rite one or go with one at the hub itself..It is a shame that my first ride is held up because of a little spring but on the other hand it is rather important..
