I was under the impression that Bad Marinas, Bad Mechanics, Bad Suppliers and owners who skipped on their bills.... could not be mentioned by name on this board.

I am thinking that perhaps Hyrdomarin took an off the shelf Sundstrand type 18 pump, and marinized it by putting it in a cast aluminum enclosure and adding coolers. Can anybody confirm this? I guess I'm concerned that when I tear the pump down, I find something that needs to be replaced, and no parts. Plus, I'm not an engineer, mechanic or any other profession that would help. I'm just a guy with a boat and a hydraulic system that nobody wants to work on, at least where I live.

what do you all think?[/QUOTE]

I can't say anything about Sunstrand 18 unfortunately ,but I just can tell
that 5-6000km more East (south of france)"a guy with a boat and a hydraulic system that nobody wants to work on"... is exactly my case too !

Thanks to Gord i could download some sketches of this pathetic system .Does anyone knows whether other motors than F11/F12 Volvo-Parker
units have ever been mounted with a R30 farymann ?

Did somebody had oil leaking through the prop shaft tube(is it sternpost?)
which makes me fall into low disrepute among my neighbours when i run
the gear ...and ruins my hydraulic oil budget ?

Are you having a problem or are you just posting more info?

I have a feeling that hydraulic motors have some kind of common standard....kinda like electric motors (for interchangability)

YES I have " oil leaking through the prop shaft tube(is it sternpost?)

I hope it is the
seal (the spring-in-it type) on hydraumotor shaft only !

Btw ,answering a question you asked ,on a UK forum I think :Yes you
have to
take the boat off water to fix this motor as long as these seals stop
oil from leaking outside and salt water to enter in the same time.

And of course you can use an other motor but you'll have to find one
whith identical characteristics (power ,speed ,shaft diameter & lentgh,
coupling diameter ,etc) and ,even used ,they are expensive .

lemnf, I owned a Farymann with hydraulic drive on a Bayfield 32 some years ago and loved the system. It allowed you to dock without touching the throttle by 'feathering' in the amount of drive and, of course, there is absolutely no clunk in changing from forward to reverse.

I found a hydraulic mechanic in my area who had worked in that capacity on cargo vessels and he found the system to be well designed and easy to work on. He also opined that the drive system could be readily (and quite inexpensively) replaced with one designed for a lawn tractor, if necessary. Does the system have to match up exactily with the original? Not according to him. The swish plates on most systems can be readily adjusted and the prop shaft, at least on mine, was simply bolted on to the drive pump, or hydraulic 'motor', which should allow a retrofit with minimal modification.

The fact that hydraulic fluid is leaking from your prop shaft suprises me - on most systems I have seen, there is a prop shaft with a standard stuffing box and the shaft attaches to the hydraulic 'motor' portion of the system; is yours designed so that the shaft from the 'motor' exits directly through the hull?

Brad

Hi Brad, it's true about easy docking but it's rather strangely noisy too .
Besides it steals a rather large percentage of the diesel motor power .

About your question :"is yours designed so that the shaft from the 'motor' exits directly through the hull?" the answer is almost yes : the hydrau-motor's
shaft is coupled directly to the prop shaft whith a mechanic thick tube (is it 'packing'?) and "mecanindus" (strong split pins) .So if you unscrew the
'motor'flange bolts ,the sea enters the boat .
All hydrau-drive I've heard of in europe are mounted that way .Maybee you'll check with Gord's links 'hydromarin'sketches on precedent page. That's why it's not so easy to adapt a roughly similar hydrau-motor .

Your are right :a regular stuffing box would allow any intervention on the
system without craning the boat ,but ,on the other side ,no worrying about
the usual stuffing boxes leaks since the motor shaft seals do the job for many years .But NOT ANY MORE in my case !

I will try to locate a replacement model # for you.

Keep in mind what I said about common standards...i.e. Mounting Flanges.

There is a company in the states called Motion Industries.....they may be able to help you with seals.

problem with clutch lever

Hi all,

i also have a faryman with hydromarine hydrolic pump, and i have the problem that the clutch cable will not stay in the forward position. It just goes back to neutral slowly.
Now i have a document that states i should tighten a screw on the cable brake on a lid, but i am not sure where this is located.
Can anyone help me find this thing ? I have checked the backside of the lever itself, and i can't tighten those any more than they already are, unless i file away some metal from in the middle of the clamp.
