Rebuilding rear Olin shocks

[Bigbill]

What’s the average cost of getting Olin rear gas shocks rebuilt. Estimated cost, Ball Park figure. I have six pairs of Olin’s.

 

[justintendo]

call drew at WER...6 pair is going to be a good amount..

 

[Bigbill]

I’m thinking one pair for one bike at a time. Don’t want to break the bank. These aren’t cheap used.

 

[squid on a 300]

WER abt $600-650 a pair as long as they dont need rods...call drew and tell him what you have...he will give you a budgetary ballpark...

It has been a few years but about $200 for a new seal head kit clean and reassembled. I have only had 2 sets of itc ones done, no leaking yet.

Plus driving time about an hour and a half one way two trips unless can combine with some other errand.

I have two of the 83/84 it’s blue Olin’s, three pairs of the copper colored Olin’s with the hose and gas bottles and one pair of the ‘82 ohlins black colored. They sell the rebuild kits but I have no way to gas them. I built giant gas shocks for the 155mm howitzers. There filled with 200lbs of nitrogen. We had a special hydraulic fixture to cycle these shocks that’s a way of testing the valuing.

I’d rather let the pros do them.

 

[fran...k.]

Ohlins seems the way to spell it. Kind of doubt Olins is a spell checker modification, those can get frustrating on some devices.

If you really want it set up for a big rider different springs and revised damping internals would be advisable.

There are shock places that charge by the hour to test valveing(?sp valuing?)

Why not check some of your local shops and ask if they can recharge the shocks for you . Not sure about what they would charge $$$ to do it or there could be others that have the equipment to help you out and save some $$$ .

 

[justintendo]

fran...k brings up a good point. if you are going to spend the money having them serviced, get them set up for the weight of the rider who is using the bike.

 

[Bigbill]

You guys bring up some good points. I don’t think I’ll be riding much. So set them up for my son.

You dont need to use nitrogen, go to a bicycle shop and buy a high pressure shock pump and use plain air.

 

[dumpbear]

How much air pressure do you put in them?

 

[silverstreakNZ]

10 bar is about the norm

 

[dumpbear]

Thanks silverstreak had to look at a conversion chart didnt know what a bar was.

 

[Bigbill]

10 bar = 145 psi. I can rebuild them myself and pump them up. Saved a bundle. Thanks.

 

[fran...k.]

A bar is basically an atmosphere about 15 psi or 30mm of mercury.

Using air is probably not worth the savings. Nitrogen does not have oxygen or water in it. All you need is a high pressure cylinder, a regulator and some hose and fittings. I do not know how much it would cost to have a bike shop pressure them up, or someone that runs nitrogen in race car tires or an Hvac guy or even some beer like substances specify nitrogen to propel out of a keg instead of carbon dioxide. Basically the same set up I use to blow out expastion chambers.

 

[Kartwheel68]

Air is free (and 78% nitrogen) and you can get a good quality bicycle shock pump for $25.

Gang,

I have the nitrogen charging setup, the high pressure regulator is $$.

Bike shops should only charge you $25-$35 for a refill, if their honest.

I had my Nitrogen bottle refilled about 5 years ago & it only cost me $13.

It’s still 3/4 full & I’ve recharged 5 sets of vintage twin shocks for friends.

Also top off about 10 modern single shocks.

If any of you are in the Houston area, I’ll charge yours for free.

Also if you can get them to any of the Texas AHRMA , I’ll do the same.

^^ Good carma to you my friend. Thanks for helping out those in your area.
