Teleflex is a great company to work with. They have very strong customer service and support. And their products are excellent!

Nicely done Jimh. Thanks for taking the time to put that together. So far so good on my 1988. No leaks yet. On a related subject, is the helm housing cast aluminum? Mine is flaking paint pretty bad and I'm wondering how much sanding and priming, if any, I have to do if I paint it.
I took my steering wheel off a few days ago to get ready to paint the housing. I had to drill a very shallow pilot hole in the end of the steering wheel shaft to keep the puller from sliding off. Looks like you did the same.

Very good article Jim. Good pictures and very straightforward info.
Are the pictures taken from the helm of your 22 Revenge?
The SeaStar website linked to the Teleflex site is also a very nicely built website. Great info and graphical overviews.

jimh,
My steering pump hasn't started leaking yet when it does I'll feel comfortable doing the pump seal replacement. Congrates on the new boat,it looks very nice. See you in a couple of weeks!

Between LHG and I we have four Boston Whalers with hydraulic steering with Teleflex helm pumps from approximately 1986-1990. I believe all four boats have had their shaft seals replaced in the last year or so due to leaks.
The picture were taken aboard my 1990 REVENGE 22 WT WD. The fourteen previous years have been kind to the teak in the cockpit.
The helm housing appears to my eye to be aluminum. Flaking paint my be a result of a little spilled fluid and a lot of time in the hot sun.

Thanks Jim for the information. A picture(s) is worth a thousand words.
rtk posted 07-12-2004 04:44 PM ET (US)
An excellent reference. I just checked the fluid level in my helm the other day, it is low and appears to be leaking a little from the helm. I was considering replacing the helm since it is around eight years old. I will replace the seal instead, thanks! I had no idea it was that basic of a procedure.

Update: added Teleflex part numbers for the seals and notes about their usage in various years.

At the price of the Teleflex hydraulic fluid, about $15 a bottle, a new $7 seal will pay for itself in a hurry.

Couldn't have been a better time for me, the seal is shot on my brother's 76 Outrage, I ordered the seal today and then saw the article. Perfect timing, thanks Jim.

Jim -
I removed my wheel this weekend and am faced with being unable to remove the cover plate that covers the seal - unlike your photo, my cover plate "hugs" the shaft, and cannot be removed because of the raised key on the shaft.
Does anyone have any suggestions?
jimh posted 12-21-2004 08:17 PM ET (US)
I key may be removable. Look closely at it to see if it is a separate piece that can simply be taken out to allow the cover to be removed.
Remember: everything gets assembled, so it has to be able to be disassembled!
Peter posted 12-21-2004 08:19 PM ET (US)
Dave, shoot a picture and post a link.
wwknapp posted 12-21-2004 08:19 PM ET (US)
Buckda:
The key is a separate piece in a milled slot. It comes out. Normally you can grab it with pliers and rock it out end for end. Don't rock it sideways or you will enlarge the keyway. You may also be able to slip a small blade screwdriver under one end to get it started. It's a tight fit. If that does not work, the slot is typically sloped at the ends and the key can be driven out up that slope. Remember if you get to doing that you are driving against the bearings in the helm.
Jimh:
Quad o-rings are available in a number of materials from the o-ring suppliers. They are not unique to Teleflex. Quad o-rings can probably be found pretty easily in a emergency.
There are also special picks designed just for the job of pulling that sort of seal. Come in sets of various shapes.

jimh:
Just because something was put together is no indication it can be taken apart without damage. More and more we are seeing pop together or welded/rivited/glued together assemblies because it's cheaper for the manufacturer than a few screws. That can result in some pretty expensive throw away parts. It's a bit of a arms race, can we figure out how to take them apart and fix them faster than they can figure out ways to make it harder to do. I'm getting pretty good at these arcane things, but sometimes most of the repair time is in figuring out the latch order for the hidden latches. Just where to probe first. The actual repair inside is often nothing by comparison. (like replacing the battery in a iPod, for instance)
Luckily, the key on a shaft is not one of those things. Probably all the helms that take a 3/4" seal will have to have the key removed. Just a guess.
Walt
Buckda posted 12-22-2004 09:33 AM ET (US)
Thanks - I'll give that a try.
Peter - Look at JimH's helm...around the shaft there is a sliver ring at the base, and the seal is outside of that ring. Take away the silver ring and you have my unit.
If it makes any difference, mine says "Teleflex II, Canada" on it. It should be a 1986 era model, and has leaked for so long that the powder coated paint on the helm has begun to flake away as the fluid has seeped under the paint surface...probably over the course of many years.
I'll see if I can gently rock that key out with some needle nose pliers and a thin flat-head screwdriver, rocking it from front to back instead of side to side....and will post results here.
Dave
wwknapp posted 12-22-2004 03:28 PM ET (US)
Buckda:
The silver ring is actually a shoulder on the shaft. It's a 1" shaft on in from that point. May have been done so larger, and thus stronger bearings could be used. Or for some other design reason.
There is also a beefed up commercial version of this helm.
Walt
Buckda posted 01-03-2005 10:05 AM ET (US)
Task accomplished. Thank you for your assistance and advice.
The "key" came out with a firm tug on a pair of vice grip pliers clamped to it.
bcorbett posted 07-05-2006 04:01 PM ET (US)
I am having trouble finding the quad ring itself. Any suggestions?
Joe Kriz posted 07-05-2006 06:13 PM ET (US)
bcorbett,
You can special order the quad ring from Surplus Unlimited.
https://www.surplusunlimited.com/storefront.htm
They also take PayPal which is a nice feature if you have money in your PayPal account... :-)
I believe the quad ring was $3 or $4 plus shipping

I have a 1989 Outrage 20 with a 200 hp Evinrude. The helm pump says "Morse Control" between the steering wheel and fill cap. I have a very slow leak from what appears to be the steering shaft seal. I pulled the steering wheel off to compare my helm pump to the one in the photos of the featured article. On mine, there is no cover over the seal. The seal is exposed. The shaft is 3/4" diameter. My question is: Can anyone tell me if the current teleflex parts listed in the article will fit my helm. I would like to replace the seal and upgrade the cap to the vented one. I looked for a model number but could not locate one. Any help would be appreciated.
Henry posted 05-31-2007 02:32 AM ET (US)
Does a 1988 17' Montauk have a helm pump which contains fluid that might leak?
Can you tell me the exact size or other identifying information for the puller shown in the article so that I can buy the right tool? Thanks.
