  1. OWNER - I own a Hatteras Yacht
Hatteras Model
41' CONVERTBLE-Series II (1986 - 1991)
I need to know how much a hynautic steering ram costs new vs. to rebuild for a 86 41 hat.
The local hydraulic place wants almost $1K to rebuild it ???
I put in a call to Sams but I haven't received a return call yet.
Please any info would be great.
 
Where are you located? $1K to rebuild the ram is insane.

last one I had done was under $150 for the RAM to be rebuilt plus the removal and re installation with bleeding and new fluid was still less than half that.

FYI it was in a convertible so access was no issue.
 
steve called me back. He's the man!
 
Hynautic as most of you probably well know has been bought out by Teleflex. He gave me the new Teleflex part # that the old Hynautic # has been superseeded to. Shall we say, a brand new ram is about half of what these jokesters want to rebuild mine.
 
Shouldn't be anything but a few seals and O-rings to rebuild it...
 
If it's out of the boat a rebuild should be between $50 and 150.
 
What's wrong with it? If it's leaking and the ram is not scored or otherwise damaged replacing the seals is VERY cheap. I resealed my helm pump (other end of the system, but same idea) for a couple of bucks - literally.

Getting it apart can be fun if the fasteners are frozen but other than that, not a big deal at all.

$1k to reseal it? That's nuts.
 
seal kit is under $30.
Can't wait to here their reasoning for this tomorrow.
If anyone else has any other experience rebuilding a cylinder w/prices please respond.
I'd like to print out this thread so I can bring it to the hydraulic shop.
Thanks.
 
I've got mine out and replaced with new. I was going to send my old one off for a rebuild, but after reading this (and the attached) thread, I'm going to give it a go myself. Agreed that the more we know about how things work, the better off we are (and it simplifies the blame process when something breaks!).

Thanks!
 
This should cost a few hundred max and that is generous, unless is is totallly trashed and requires more than a rebuild kit. Sounds like someone is trying to take advantage of you.
 
SKY did you ever do yours?

No, its still on the project list. My shop at the quarry rebuilds hydraulic systems on the big equipment all the time. I really have no excuse. Its just a matter of pulling it out.
 
Seriously guys these things are ridiculously simple. It's just a piston with seals so the fluid stays in and is driven the two directions by the pressure. The only "gotcha" is if the portion of the ram that rides in the dynamic seal is scored - then you're hosed and sometimes, depending on how old the unit is you're better off buying a new one simply because the replacement part may be prohibitively expensive, if you can get it at all.

I have a pretty complete O-ring kit around here because I rebuild my own diving regulators. O-rings, when bought in reasonable quantity for a given size and material, are literally a few pennies each. Even the big ones are nickels and quarters. The "gotcha" with diving regs is that the high-pressure seats are only available from the manufacturer and they do wear out; the O-rings necessary to rebuild a diving reg, if the seat is ok, have a cost of about a quarter.
 
You can have a scored shaft filled and rechromed and we do that on the big stuff, but with a little cylinder like this one, it probably is cheaper to buy new than to rework a scored shaft.
 
I picked up my repaired cylinder.
Here’s what was on the receipt word for word:

_______________________________________________________
“Manufactured new cylinder rod as per sample

Replace 1 Tie Rod
Replace Eye Assembly
Replace Head Bushings

Hone Tube Clean
Complete cylinder rebuild to include:
Degreasing of entire cylinder, disassembly, sand blast head and piston. Inspection & re-measuring of all seal grooves, inspect bore of cylinder for scores, inspect pin eyes wear, polish rod and check for straightness and imperfections. Reseal/reassemble and test external as well as internal leaks (by-pass). Job is then stamped with your invoice number & painted **1 year warranty**”
____________________________________________________________

IT WAS ALMOST $1K. !!!
But after I quickly informed him that a new one was less than $600, the price was magically reduced to $375.00

I must say, in his defense that he truly felt (knowing that this is a charter boat and I cannot afford down time) that he did the right thing and he was justifiable in his original price and wanted to make sure he did a top notch job.

He did admit that there was a large lack of communication to me on his part and that he would have told me to buy a new one from the start if he had known the price of a new one, he also stated that the rod was pitted and had to be replaced. (although I don’t recall it being pitted)
He also stated that after investigating the new Teleflex version, that it would not be as heavy duty and alluminum with a tiny shaft vs. the heavy duty origial Hynautic. (He did have a point).

The moral of the above story is, get IN WRITING an estimate of any work you’re going to have done. My fault, amateur mistake, I knew better than that. It is my fault for once again assuming that other small businesses run their businesses the same way I have ran all of mine.

Chalk it up as another “learning experience."
 
I Just dropped off mine today at Rose's in Gloucester,had a slight drip.They told me no more than 160.00 to rebuild it.Its an old Hynautic off of a '83 36'Convertible
 
Sounds about right. That's what I expected mine to be.
 
Just make sure the O rings and seals you use are compatible with the fluid your using.
Repairing low pressure cylinders are a piece of cake. Most are a clean and replace seals and O rings. Scoring is seldom seen in a low pressure system and seldom need honing. The shop repair was a rip off.
