Bike Stand Repair

Vincent · Banned Joined: 16 Oct 2006 Karma :

I went to use this stand to move my motor around the other day and the pedal is seized. It looks like the shaft on the cylinder has completely rusted up.
Anyone know if they're repairable? Can you get spares or repair kits? Also, if anyone knows the make it'd be handy Thumbs Up

TIA, V.

Looks easy enough to dismantle, a couple of split pins and a spanner?
I'd be looking into that one myself I think, nowt to lose.

This looks like a pretty similar set up.

Pull it apart.
Remove the 'Gland' and rusty piston assembly. Clean off as much rust as you can.
The piston will probably be held onto the rod but a nut on the end or a big screw in the end of the piston rod.
Remove the piston and then emery cloth/wet and dry the feck out of the rusty rod.
It will never be perfek but it will work as well as before.
As long as the piston seal is good.
Some 'jack' pistons use leather cup type seals which can be fragile so take care on assembly.
Re-assemble and fill with fresh hydraulic oil. (You could use ATF).

Cheers

I presume the shaft and piston are a one-piece affair? I was wondering if I could get someone to knock up another shaft. What's the correct terminology for that "shaft" BTW? Is it a con-rod or just a piston?

That's knackered it, the piston was completely siezed so I thought I'd get a bit of extra levrage, didn't see this coming Rolling Eyes

Now it is scrap metal becasue I'd be very surprised if I can get a replacement Mad

Just clean the shaft with a strip of rough emery, put it back in and give it a whack or two. Re-fit spring and pedal.

Ahh, I see it's too late for that. You could have rolled the emery into a rope and pulled it through the spring, been done in a few minutes.

Excellent photos Sir.
They are too good for this forum as I can actually make out what I'm looking at. Smile

Those sort of things are 'usually' made from 'nominal' size/diameter bar stock. (i.e. 5mm 10mm 1/4" 1/2" as opposed to a custom 'turned-down' in a lathe sort of a size.)
If you get stuck for spares, you 'may' be able to cut the shoulder of a long-enough bolt to length and drill the pin hole to suit. If you're stuck.

Cut the end off, clean with emery, punch out the ram, clan with emery some more, replace the ram, weld a big nut on it sideways. Re-fit to jack, pin goes through hole in nut. 15 minutes work.

That's what I like about you Pete..........you may have an engineering workshop at your disposal.......but you've still studied the dark art of "improvisation" Very Happy

The pistons been soaking a couple of days, I'm home now, will get my "Coffee table" vice out and have a go at hammering it free. No welder though, which is OK as I can't weld for toffee anyway Embarassed

I'll see if I can get some local assistance and get a new one made up.
