I broke a support tube the other day (10 months hard bocking so not bad)
I have heard that a few people have had trouble fitting these and as it only take a short while if you know how I thought I would do a tutorial
Before we start I have demonstrated this on a frame without a spring on it (Bocks were at work) but it works the same with the spring (I put it back on the ones at work
To start with you will need
2 10mm spanners
2 13mm spanners
1 set of external circlip pliers (you can do it without but it is hard work and they are fairly cheap)
Pic 1
First you will need to loosen nut and bolt (A) don't remove just loosen
Next you must remove nuts (B) and (C) you may want to fix nut (D) in place with some tape to keep the adjustment right
Do this on both sides
-
Now you need to release the circlip very easy with the circlip pliers ( I bought a pair of cheap internal/external ones for about £5 a few years ago)
It is possible to do this with 2 small screwdrivers but hard and you risk damaging the circlip and stabbing yourself in the hand
You only have to do this on one side
2 pic to show how it works
-
Next you just pull back on the upright and footplate and the threaded rods slide out of the holes in the support tube
Dead easy but getting them back in when you fit the new one 3 hands :biggrin: so enlist a mate
-
Now remove the loosened circlip and just slide the support tube out (may be a little stiff I used pliers)
To install the new one just reverse the above instructions and make sure you tighten all nuts (I forgot the big one at the back not a good idea)
Hope this saves someone a bit of grief and time

A fantastic tutorial Jason, well done :)
-
Couldn't you use your foot as a third hand :biggrin:
-
I just managed to tease the circlip up and off the support tube, and back on the same way too :thumbs:
-
wicked tutorial there jason, few days late for me but still great.
i found them support bars quite easy to get back in, i sort of pulled the top out with the back of my hand while pushing the ends in with my thumb.
it straightened them just enough to slide in.i also completely removed nut and bolt a though
-
I may need to change mine before long, they have a real big bent at the top, and I wouldnt be supprised if they break before long.
Also, then the entire top of my bock moves :-\ I'm a little worried, theyve done it for ages, the calf support and knee bar all move forwards, pivoting around somewhere in the calf pad area, everything is tight, but it still moves!
-
I've just pull a plate completely apart ( need some part off it )
That :censored: circlip :banghead: if you don't have the right tool for the job it's just about impossible >:(
But where's there a screwdriver there's a way ;D
-
lol, i paid £8 for some crclip pliers from halfords, these were initially the madest tool ive ever seen, pliers that open when you apply preasure

hybrid_hex It sounds like the 8 pop rivets inside the plates that hold the knee bar have sheared if you have access to a pop rivet gun (you must use them at work a lot of aircraft bits are held on with them :biggrin:) it should be very easy to replace them
Just undo the 4 hex head bolts that hold the kneebar on and pull them out that will release the calf pad, the 2 clamps (plastic shapes) and the kneebar then you should be able to see the rivets 4 on each side
I don't know what size they are but most car spares and hardware stores stock a wide range
If you have to drill them out make sure you get the right size drill as they don't work well if you use to bigger drill
Get them done soon because if they all shear you could bend the back frame by banging the bolts against it when you bounce

Cheers Jason, sounds like a plan, Im working nights as of tomorow, so Ill bring them into the hanger and have a look, Got all the tools you could imagine available, and if we dot have them, then we use a hammer and a screwdrive, its amazing how much they will fix!! (its a good excuse to go for a bounce at work aswell!! :banana: )
-
Always glad to be of help to the forces got to keep you fighting fit or they might enlist ME :haha: :thumbs:
Jason :Hoofies2:

If they did enlist you then you would be kept under lock and key inventing things like Leonard de Quirm! :thumbs:
-
They wouldn't want me, lol I may be too much to handle!! :biggrin: :banana:
-
The army would have you, but you would never join, as you would have to cut your hair!!! :thumbs:

Jason, I took my stilts apart last night at work, and what should I find but no rivets(im on PoweriZers) but two bolts, one above the other, on one boot they were loose, but on the other, both nuts were completely detached, and the only reason the bolts hadn't come out was that there wasnt room! Im so lucky, it could have been desasterous! Cheers Jason! :thumbs:
-
hmmm very odd
-
Glad to be of help mate last thing we want is a damaged Hex
I hope you put them back with a bit of thread lock to keep them there
And I bet they feel better now :biggrin:

Hmm, I am so going to be using this when i can get ahold of the bar, and a new foot plate, and the other plate between the foot plate and the hoof, and probably new support rods . . . . . . bugger.
-
Whats a support tube xD?
ooo ur the jason people talk about new rubber soles...
-
Support rods. I did my own tutorial, here:
