haskill re-build kits so $$

[v101]

So I have a Haskill mini sport booster, its due for a service / re-build. I checked on the re-build kit parts, and why the cost is so $$ for the kits?

i can get it re-build for around 1500.00

thinking if I have to get this done every few years, is there any specialized tools needed to do a re-build on these?

Has anyone worked on these and taken apart to rebuild or replace the o-rings on them? is this very difficult ?

The air drive sections are pretty straightforward. IIRC, the only tool most people may not have is some snap ring pliers to get to the air spool. (Hint: push out the air spool from the air inlet with something like a pencil) The boost portion is a little more involved.

I may have a copy of the maintenance procedure, I'll have to search a little.

Found it, maintenance, rebuild procedures, and diagrams

many thanks!
so for the 0-ring kits that are sold for Crazy markup, are the o-rings standard ones I can buy from where i typically buy my o-rings, which is the scuba department of mccaster carr ? or is the re-build kits include "other" parts that are not just o-rings?

I forget what's the sizes are. IIRC, The air spool and sleeve are standard sizes. A smaller standard size will work on the stem if the rubber part is damaged. For the air drive piston it's a little tricky. I matched up an o-ring from an older Catepillar diesel trucks oil filter that was a perfect match, no idea what the size was. The gas section has some standard sizes and some parts I wasn't able to match to anything (may be proprietary, I just used the kit I had).

Be careful with o-ring materials when matching them after-market. You should use Viton over Nitrile in oxygen rich environments.
