I am installing a new used Hynautic steering system in my Bertram 38', in the process I noted I hade a veriable speed Helm steering pump with no resevor, large Teleflex cast aluminum steering box, meens resovor is part of pump.

The Hynautic came with Billit steering box with remote storage tank, hoses, and Rams for drives.

My ? is =
Can I use my old Telflex steering box that is Veriable speed steering with the rest of the Hynautic system.
Also not use resovor that was with Hynautic Billit helm.
Thanks

Yes in fact that would be the best way to go. The hynautic helm makes for a heavy wheel


I disagree. I have a Hynautic full hydraulic system on my Dominator and can spin the wheel with my finger.

If you plumb the system for power assist, you need to include a reservoir. If you plumb the system without power assist, you don't include a reservoir. The HyNautic helm you have can be plumbed either way. Its probably an old H-40 or H-41 helm(which is a good helm & can be rigged for manuel steering as well). The # is stamped on the side, usually with the date of manufacture as well. Including a reservoir is very simple & was probably mounted on the engine or in the engine compartment at one time. Its just one hose leading to a reservoir tank on an assisted system, thats mounted barely higher than the engines P.S. pump to gravity feed the pump. Just buy & install it. You need it to ensure the pump never cavitates or runs dry. The other helm sounds like a TeleFlex Capilano 1250V or 1275V with the "friction" adjustment knob on the bottom. This helm is better used for manual steering plumbed systems, for performace outboard applications. You definitely want full power steering on a 38 foot Bertram.

Superman, thanks for the tips, wow you know both systems I have. The resovor for the Hynautic helm was mounted under dash by helm, no power steering pump at all. Both systems are manual. i just thought the variable helm seems to be the way to go between the two helms. Just kill the resovor and use the teleflex.
Thanks Superman

Calling Superman

I used the old teliflex helm with the Hynautic rams and lines and divider block. Today I finaly finish and started to fill and turn wheel. Drive turned one way, then the other way, then wheel locks up and drives go nowhere.
I cracked returned line at devider block and nothing, also at helm no fluid or air.

Do I have to use the hynautic helm and resivoir with the rest of the system hynautic hoses and rams . Dam it, I never have any luck.
:confused:

H41 was stamped on the hynautic helm., resevoir has all instructions on how to fill system and 40 turns to left, then 40 turns to right. And crack bleeders. Where are the fricken bleaders.

Wow, Scott. I haven't seen too many 14 year old boats with such a sexy transom.

Air Lock

You must rig up an "I-V" bottle & hose & rig it to hang above the helm. Get a fitting that fits into the fill hole of the helm without leaking. Hook a clear plastic hose to this fitting, going up to the plastic gallon jug with the top cut off. Keep this filled with ATF DexTron ll, while slowly turning the steering wheel lock to lock. Stop without forcing the wheel, at the end of each lock. NEVER let the bottle run low on ATF. When the system seems full, crack the steering cylinder fittings SLIGHTLY, to allow fluid to drain into a clean container, while a helper slowly turns the wheel, until most air bubbles stop flowing, and tighten the fitting. Same on both cylinders. Pour the caught fluid back into your I-V bottle. This is definatly a two man process. Let the system settle overnight & do it again. When your all done, and the system does not work...you have a defective helm. Cleanliness of hoses, fittings, fluid, etc., is very critical to the check-valves in the helm. I always place a new disposable paper paint strainer down in the I-V bottle to catch any debris.

Is DexronII the choice for these helm pumps and hydraulic cylinders? I always use Dexron III in my power steering pumps. Is Dexron II still available?

I have been useing Hydraulic oil, none foaming high pressure oil. I hope that is not my problem. I used the same oil in my trim pumps also. Mistic Oil I belive.

OK, Today was another waisted day. I believe the helm is not going to work with current Hynautic lines and divider block configuration . there are two more Ts in the rear by the divider block. After system was blead, lock in bleaders one at a time are 40 turns and helm just locks up.

My next step is to change out the helms and include the damn resovor and pray for the best.

Too much time waisted already. :(

Dextron ll, Dextron lll...same difference. Yes, this is what is used in all manuel & power-assist systems. There is a steering oil used in low temperatures made by Texaco, that HyNautic supplied with every system as standard. The advantage was slightly lower viscosity over ATF(5W versus 10W) & did not freeze & was also used in aircraft. But nobody uses it anymore in boat systems.

In the process of nothing working , i see I must use the hynautic helm and storage tank.
#1 Teleflex is just not working with devider block. there are extra Ts in the hoses in back where as the teleflex doesnt have that.
There are also check valves at each exit of the teleflex and hynautic has not.

I can bleed the air out with the bleeders screws on the devider block for port and starboard like it says 1 at a time. works great untill you lock in the bleeders then wam, steering wheel is locked up tight. I belive the Hynautic helm has a two way supply/return per starboard and port ,plus the return line. Where as the Teleflex has only 1 way fluid from starboard and ports supply exits do to the check valves that I can see and feel with lines off the helm., plus the return line.

It sounds like you have your steering lines plumbed incorrectly at the back of the boat. They are suppose to cris-cross each other on the inside of the transom, before they go thru the thru-hull fittings. Easy to swap.

Superman, that is the first thing I did is switch those lines, after switching lines the wheel only turned one way and locked up going the other way.

I will take pictures of it this week and show you the direction of the lines.
Solo is lost for now. :confused:

Ended up using the the complete Hynautic steering system, and yes, it is a heavy wheel compared to the teleflex system. Oh well.
All in all the new system is more trick than old setup.seems a tad more brute.

That was my last pain in my @ss. some petty things now and I will splash, no more suprises.
Solo :D
