REFLECTOR: Main Gear Actuator

Tue Apr 1 20:32:16 CDT 2008

You know the mind plays tricks on you in your old age, I know I tried the shim installation but I also tried a large o-ring to fill the C-ring groove and I can't remember which one worked better, or was the final solution that allowed me to install the seals without damage.

Andy,
I like the shim idea.  Wish I had thought of that.  I just held my tongue just right.  Didn’t work very well.  Third try no leak though.  I did the sand paper edge removal also.

My new main gear cylinder leaked new from the factory. Yes you do have to remove the fittings to remove the ends. After removing the C-ring, I pushed the shaft end-stop and seal assay. towards the center of the cylinder an inch or so, to gain access to the C-ring groove. Save yourself some trouble and use some 320grit or finer sand paper, and remove the burs and keep sanding until you have a small radius on the leading and trailing edge of the C-ring grove. I also used a piece of plastic cut out of a milk jug like a piece of shim stock over the new outside o-ring seals, to protect the seals in the same manner that you would do to start a set of piston rings into a cylinder. This is tricky to do but the only way I could keep from damaging the new seals. Even with the C-ring radius, it can still damage the new seals when you try to put everything back together. The new seals will expand inside the groove and when you try to force them past the groove it
 usually damages your new seals. I damaged the first set of seals without using the shim stock. Your milk jug plastic shim stock has to be the exact diameter and not overlap itself inside the cylinder. Use the thinest plastic that you can find. You should verify that your plastic is thin enough by first leaving the seals off the shaft end-stop and checking the fit. Your results my varry this worked for me.

One must remove the two fittings -one at each end to get the cylinder apart.  That is usually the mistake.

Check to see if there is a burr on the snap ring groove... That might be holding it in...

I tried to disassemble my RG STD main gear actuator to replace the seals last night and ran into a dead end.  I removed the snap ring at the end where the actuator shaft exits the cylinder and could not extract the piston.  Is there something that Iʼm missing?

It is an ARO TEK actuator.
