Hynautic Head Repair
Posted: Sep 26th, '09, 20:26
Well after several years on the original head (33 to be exact) the inevitable finally happened.
Last Hudson trip there was the first drip of hydraulic fluid under the helm. Didn't loose pressure and certainly nothing to be concerned with safety wise but a leak non-the-less.
I drained the pressure off the system and removed the steering head (H25 near as I could tell).
I pulled the head apart and found 2 seals that needed replacing. Both were on the shaft and then the top o-ring was replaced for good measure.
Its amazing that parts were still available for this vintage product. It seems that one kit is available for all of the H2X series heads.
If anyone has a leaky head, don't be afraid of the repair. Be sure to work clean and put a little vaseline on the parts before assembly. I used a stainless sheet to work on and cleaned the parts in a solvent and brass wool, then I dried them with compressed air. The hardest part will be refilling and bleeding the system (really not that hard at all).
Working with hydraulic fluid is tougher than 5200, it seems to get everywhere even when you think your being neat.
