    Yacht Specialties Pedestal Disassembly, with Photos

    ( For Edson pedestals: https://backwinded.com/2015/12/07/re...d-stop-cables/)

    This pedestal is on a 1984 Ericson 381, but the general idea is the same on all YS/Merriman pedestals (which are identified by the "YS" on the wheel nut).

    The job isn't difficult, but there are many pieces. A photo record or notes is useful when reassembling.

    The sticking point is often seized stainless machine screws in old aluminum castings. A penetrating lube such as "PB Blaster" is required, along with patience and the usual bag of tricks.

    The following sequence begins after removal of the pedestal guard, steering wheel, and compass. A helper is (very) useful, although the job can be done alone, with Vice-grips set below deck.



    1. Remove the large stainless countersunk bolts from the deck. The nuts beneath also secure the quadrant sheaves assembly box. Let it sag, but note how cables, chain and 12v wires are routed through their openings.



    2. Remove four stainless machine screws from the shift housing collar ring. Set ring aside.



    3. Remove throttle and gearshift arms. They are fixed to bronze levers visible in the rectangular opening. Loosen the set-bolts (see Picture 2) and pull the throttle and gearshift arms out horizontally. Remove the four stainless machine screws securing the shift lever housing.



    4. Pull the shift lever housing up about a foot. There should be enough slack in the (Morse or Teleflex brand) control cables to permit this. If not, detach the control cables from transmission and engine. It's a good idea to replace the cables with new ones anyhow The difference is butter-smooth rpm control and gear shifting.



    5. Detach the shift lever housing from the cable connectors and set it aside.

    6. Detach from the control cables the bronze lever arms. Set them aside. It is a good idea to put all kindred parts and their associated pieces into separate well-marked sandwich bags. Misplacing any of this stuff is disaster.

    7. The cable-end holders are attached to the cables by a set screw. Loosen the screw, push off the worn-out rubber telescope gaskets, and the cable-end holders will slide off the cables. Note how the holders work: the set screw holds the cable jacket. A common cause of problematic shift and throttle controls is that the set screw has lost its grip.

    8. Remove the pedestal guard connector plate that receives the guard tubing If this delta-shaped piece is broken or frozen, it can be successfully remade in King Star Board. The control cables can now be removed for replacement, or left where they are.

    9. Observe the wheel brake assembly. The adjustment knob shaft is held by a set screw. Remove set screw and withdraw knob shaft horizontally.

    10. With rudder centered, mark center top of the steering chain with string or cable tie. This helps during reassembly.

    11. At the steering quadrant below deck, detach one steering cable from the quadrant. Note whether the steering cables are crossed in the pedestal, so they can be reassembled correctly. At the pedestal, pull the loose half of the chain up and detach it from teh quadrant wire by opening the master link.

    12. Allow the disconnected half of the chain to fall through the deck. The pedestal is now free, and can be lifted, leaving the other end of the chain on deck.
    For painting or other exterior repair, the brake shoes and the sprocket can be left installed.

    To remove the sprocket and shaft, first remove the brake shoe assembly by unscrewing one side and sliding it off the shaft.
    Locate and remove one set screw on the sprocket.
    Locate and remove the roll pin that secures the sprocket on the axle.
    The roll pin goes all the way through the shaft, and can be gently knocked out the other side with a drift pin. A new one will be necessary, in stainless steel.

    13. Note that on this stock YS pedestal, the base is connected to the tube by only three short welds. My former pedestal broke, so I no longer trust that connection. The YS aluminum bases themselves are subject to corrosion to the point of destruction. If in doubt about integrity, any welding shop can make deep-penetration welds for added security. If the base is a total loss, the tube can be sleeved and a half-inch base plate welded on as a substitute. ( http://www.ericsonyachts.org/infoexc...destal-Rebuild )

    Yacht pedestals during heavy weather have to support several crew simultaneously grabbing and lunging for support, and a standing helmsman has no other means of support but the wheel itself. A strong pedestal guard is necessary in addition to a sound pedestal, and set screws at bases and spreader arms should be tight to spread the loads.

    Every 30-year-old aluminum pedestal--its base, guard, gears, wheel, sprocket, chains, sheaves and quadrant--benefits from careful examination and a skeptical eye. A bit of maintenance now may head off the breakage of an irreplaceable part, or crew member.

    Merriman Binnacle Instructions and Part Numbers

    I have a 3.4 mb pdf catalogue with part numbers and instructions from Merriman. It exceeds allowable upload size. I thought it was a terrific discovery and would like to share the information. Please advise on adjustment to file size or appropriate place to store this document.

    I forwarded this to Sean, the site owner. He is working on many fixes, including the archives.

    Sorry about getting so late to this game - I lost my login credentials on my work computer and had to wait, and then kept missing the window after work, etc...

    Anyhow - the upload:

    Can you scan the documents you have into a pdf format? If so scan at 150-200, and advise how big of a file it is, etc. I can set up an upload, etc.

    You can email directly through the "Contact Me" link below...

    Thanks for the contribution for EricsonYachts.org!

    PM or email to me and I'll email them to you. Sorry, I was never able to figure out how to post to the forum. I did have a recent adventure in adjusting the Merriman wheel brake which had a happy ending if you want the complete story...hint: the transmission lever has a half moon key in a slot that is best not dropped down the binnacle. But be careful what you wish for as more than likely I'll extol the virtues of Captain Moab's Ship Balm and All Natural Lubricant & Protectant - waterproof protection for boat and crew.

    Hello Max,
    I recently bought a 35 Mk III and need to figure out how to get the compass off the pedestal so I can access the instrument cables as I am rewiring... Any information on this would be great! I have sent you a PM with my email for the PDF
    Thanks!

    The compass case? Usually it is just removing any screws you can see (however tiny). Starting with the light fixture.

    Once exposed, the actual compass mounts should be pretty clear.

    If that doesn't help, post a photo of your compass.

    Oh, and welcome to the forum.

    Christian - thanks for the welcome! Would you believe of my gazillions of photos of bits of the boat, I don't have a clear shot of the helm and compass! However, your description fits what I saw yesterday - four very small (#4?) screws at the base of the compass. They were frozen so I did not want to force - not knowing if that was where I should start... With your advice, I will be more persistent. Thanks again.

    Yep, that's where to start. Just drill them out, new ones later.

    There is no question about our boats that somebody here can't answer, and usually pretty fast.

    Separate Pedestal Guard Connector Plate from Guard Tubing

    Great walk through. It's a logical process. However, the last I did it was before the prevalence of digital photos so I had some head scratching moments on reassembly.

    I'd like some advice on separating the Guard Connector from the Guard Tube. Last time I did this project, I just took off both together. I gently tried to separate them but with the inevitable corrosion, no budge. Did not want to break the connector.

    Any advice on this? I do have the usual suspects as far as penetrating oil including WD-40, PB Blaster, and even Kroil. I can take the two off together and manipulate off the boat. I'm guessing tapping at the lip of the holes for the pedestal is it but don't want to break the plate.
