Service Navteq Hydraulic Integral Backstay Adjuster

[wingmanII]

Hi

I have a Navtec hydraulic backstay adjuster leaking oil. Does anyone know how to serve it by yourself, replace gaskets and adding oil. My local service center want to have $ 800 to fix it.

I probably need one or more special tools to open the cylinder. Anyone know where to get one of those?

Hi,

I do not have any Navtec hydraulic backstay adjuster rebuilding experience, but did repair a Sailtec unit. Similar, but not completely the same.

Felt it would be no big deal since I already had all the tooling necessary and am quite competent with hydraulic components.

In the end it worked out, but spent pretty much what they would have charged me to rebuild it anyway. Changed the piston, seals, pump gauge, clevis fork, etc.... Even wasted one seal kit on a bad piston ($120).

Funny thing is the guy who owns Sailtec warned me about having problems, but had to learn on my own. Glutton for punishment I guess.

One thing for sure the next one goes to Sailtec.

Good Luck!!!

Ok!, Thanks for your reply, it may not be idea to try to repair it yourself then!
The thing is, the hydraulic works out but it leaks oil and I think there are only one or several gaskets that needs to be replaced. Are there additional things that need to be adjusted, I leave it to professionals. Then it is not profitable to fix it yourself. I see your point here. But $ 800 for opening it, replace gaskets, fill oil and pressure testing, I thought was very expensive!

I would agree if a reseal was all that will happen. Other posts show its no big deal. Mine was from a neglected boat that sat for about 5 years.

I had mine rebuilt for half that by an authorized service center but I did ship it out. Might want to get another quote. I do not think you have the tools. Will cost the same to purchase the tools and rebuild as send for rebuild.

The seals go bad because of UV. Make a cover to fit over the unit and it wil last longer between rebuilds.

Has exactly the same thing happen, at the start of a crossing in the canaries. Unfortunately the seals are specific to navtec, yes you need special tools and you need particular gear to pressure test it.

No real low cost alternatives I'm afraid. So some service centres are cheaper then others. Try not to look too desperate !

I had similar problems. Navtec said to send it back. I'm in panama so that's not going to happen. They finally after much whining sent the parts and the pages of the manuals. The only special tool I needed was made from an aluminum beer can. When the boom vang started to leak though I needed a hydraulic shop here to refill it with nitrogen. Talk to a good hydraulic shop. They should be able to do the job.
