Rebuilding old Konis

Looking Good.......

This is the internals as they come out of the shock body.

A one-way valve on the end of the tube - it looks nearly identical to the valve emulators that they put in forks.



Not much wear and even the rubber seals look pretty good.

I'll see what new seals cost before I decide whether or not to renew them.

The foam rubber stops are goosed, hopefully I can get them from IKON.

I also decided that it would be lazy of me to get the springs powder-coated, so I stripped the old paint off the springs and started the painting process, using an etch primer and I'll paint them up with black gloss enamel.

If I stuff it up then I'll get them powdercoated.

So these shocks are a pair of the old Double D's from the mid 70's - early 80's.

They don't have the dial on the top, but otherwise they are very similar.

This is how they looked when I got them.



I got the springs off by using a clamp on each side to pull the spring down far enough to remove the retainer cap.

The caps were seriously tarnished, but are made of a nice alloy and polished up a treat.


Tomorrow I'll see what it'll cost to get the springs powdercoated.If it's too pricey I'll paint them myself.

Well I got them apart tonight.

These are the old 76 model shocks.

Compressed the springs using a couple of clamps.Pin spanner wouldn't budge the top of the oil reservoir, but a couple of blows with a punch had them open.

Oil inside was absolutely stinking.

Not much wear on the internals. I'll see what new seals will cost, but I'd probably get away with re-using the old ones.

The rubber bumpers are shot - anyone ever seen any of these in Bursons or the likes?

Internals are a bit less complex than the ones in the writeup as the older ones dont have the dampening dial adjuster.

Quite confident that these will scrub up quite OK.

my problems been with the lower bushings wear, do you know
if they sell them seperately, doesnt appear to have them in the kit.

They look like they may well come up good Carl. I'll make a photo log of the process.

I hope you have all the parts you need   

[steptoe]

have a set of progressive shocks in the shed,, will have to go and see if they are the same,, will be handy if they are,                   have a leaking seal

thanx for the lead on that melb,, it may go some where, maybe not,

I'll be rebuilding an old set myself shortly.

Anyone done this before?
