OMC SEA DRIVE Select Trim - Blown Oil Line

[seachest]

Hello once again all, Got a major issue with the hydraulic lines on the select trim unit. The short story is a crimp on fitting on the "Piston" end of the ram failed where the hose joins with the stainless tubing thus preventing the ability to raise to unit. The OMC part number is 983543 which was updated to JohnsonEvinrude 0983543 which are both obsolete and totally unavailable. Please see the attached picture of the fitting that threads into the ram cylinder to get an idea of what it looks like. I'm not asking where I can buy one, I'm asking if anyone has experienced a similar problem and what you did to remedy the problem e.g. adapters that were used since regular flared fittings will not work Any and all suggestions are greatly appreciated

Have you talked to any shops that specialize in hydraulics ??

 

[seachest]

Thanks for your reply boobie, I have visited a number of them and also contacted some on line "specialists" the most recent of which said he's not even sure what to call the configuration I was able to slide the hose back on the tubing and used a cable clip (like the ones used on garage door cables) to secure it. It allowed me to raise the motor and get it to the trailer lock position but I don't want to rely on it as a permanent repair.

I'm not clear about the specific problem.
Does the pictured fitting no longer work or is the problem with the flexible hose that goes to it.
Perhaps a compression connector could adapt a different hose and fitting to the existing fitting.
Perhaps some automotive brake line could be adapted?
Couldn't you slide the hose on and use a couple of hose clamps to secure it.
I know we are dealing with a lot of pressure but it seems like 2 or 3 clamps might work.

Hi steelespike, I'll try to clear it up - the crimped on fitting basically rotted away. In the attached picture the actual crimp on is shown at the lower right. Hopefully it is still a good one. I was able to make the temporary repair as I described above however, from what I read in the manual the pump generates anywhere from 250 PSI up to 1800 PSI - I really don't want to risk the clamp loosening up and causing my own mini version of the Exxon Valdez. I have been advised by a number of people to avoid using hose clamps because they just wont hold the pressure. So I am trying to get new hydraulic lines made up but nobody I've contacted so far has the type of o ring flare fitting that I showed in the first picture - Also, I need to stay with stainless as all of this plumbing is submerged most of the time. Unfortunately, the damaged tubing is not presently within my grasp but I will endeavor to post a pic with the temp fix.

kinda looks like an easy fix if the ss tubing is in good shape and the connector on the other end of the flex hose isnt some odd type of fitting? id cut the ss tube, flare it, add a union and get a hydraulic shop to make me up a flex hose that would attach to the union and wherever else it connects. just a thought

 

[seachest]

All possible solutions are graciously received and gratefully considered. I'm amazed that so many commercial places are unable to make these up as when I look at fittings and hoses for power steering for vehicles it seems to be a common fitting. The other problem is that the ss tubing is only 3/16" O.D. If worse comes to worse I will have to either secure the hose to the tubing with additional cable clips or try to use a duplicate tube end hose that I may be able to route using cable ties since it would no longer have sufficient length to secure to the factory mount. But I appreciate the responses and suggestions, please keep them coming, all are considered

Thank You

http://www.ebay.com/itm/Swagelok-SS-300-6-Tube-Fitting-Union-3-16-Tube-OD-/310386666471. a hydraulic shop cant make up the flex hose with a 3/16 ss tube crimped into it? never would have thunk it!

You could cut the stainless tube and have a standard stainless JIC fitting silver soldered to the line. Then a hyd shop could make a standard hose with the mating JIC fitting. Not sure what is on the other end of the hose but I'm sure there is a solution..

I use permatex high strength epoxy when im in such situations. Its never let me down and its capacity is up to 4500psi so well beyond what you need.
I use to think id never use such a product instead of a "proper" repair but ive found the stuff to be so reliable that i dont doubt it will be fine when using it in the field per its limits in the permatex datasheet

 

[Bosunsmate]

This is the one i use, in NZ it comes in a two part product you cut and knead

Thank You nwcove for the link and info, bwrke, and Bosunsmate - Will keep you posted - :joyous: I'm beginning to realize that all is not lost with people like you around - So glad I joined this site, I've gotten nothing but positive results since I signed up !!! Enjoy your weekend !

 

[nwcove]

here was my thought...

 

[seachest]

Thank You nwcove - I will post the pic tomorrow of the actual problem , It is the crimp fitting at the end of the hose that went bad. The ss tube and flex line are still good as far as I can tell - Picture if you will the hose in the above picture without the crimp fitting that secures the hose to the tubing in the meantime

Your greatly appreciated responses have caused me to rethink this problem and approach it from a different direction I suspect that I was making it more complicated than needed by trying to locate the fittings that go into the hydraulic cylinder. Both nwcove and bwrke lit the bulb for me. Hopefully, we can simply cut the ss tubing and have longer hoses crimped on - I have attached a picture of the temporary fix I made with the cable clips rather than hose clamps - I don't think they'll last too long as they are zinc coated and will be at least partially submerged in salt water. Thank you all once again - Maybe just maybe I can get back in the water to enjoy what's left of the decent weather here in the north east.

The Best to all who provided ideas and possible solutions.

Before you go and cut the ss tubing - I think the end of the tubing, under the existing crimp, is going to have some type of flare or expansion of the tube similar to the barb on a hose fitting. When the outer sleeve is crimped it causes the hose to grip the barb of the ss line. Otherwise the ss line would just slip out. So when you take it apart, don't cut the ss tube, but put the crimp in a vice and cut the sleeve lengthwise on opposite sides with a hack saw or grinder. Peal the old sleeve off and remove the hose so as to save the end barb on the ss line. That way you can have a proper crimp put back on.

 

[seachest]

Yes, that makes sense bwrke. As I recall there are some grooves in the tubing where the crimp failed. When I put the cable clips on I made sure that the clip was positioned over the grooves. Thanks for the heads up !!! I'm waiting for a reply from a company that specializes in making up the hoses before I cut anything

Seachest,
I have the same exact problem. Needing PN 0983543. did you find a solution to the problem?
