I have a 1974 Southwind with a 351 Ford with reverse rotation (RH) engine. It has a Mallory YL554FV, the distributor has failed due to broken parts and I can not seem to find a source for a replacement. From what I have read right hand distributor are not available anymore new. I have found new and used left hand distributor’s, and AAA Marine makes a right hand gear that would convert a Mallory to a right hand. In reading post here I am confused as to whether I can convert a left hand distributor to a right hand distributor properly. I have also posted in the wanted section hoping someone would have a old distributor. Any help on this for distributor’s or parts would be greatly appreciated. Thanks in advance. Ike |

Your lucky day.... Right-hand or reverse rotation distributors are still available. Not cheap, but available. The link below will get you a new R/H high energy ignition distributor for your Ford based 351W engine. https://www.summitracing.com/parts/dui-m35820rrbl" rel="nofollow - Link to distributor (You will also need new plug wires) JQ ------------- Current 2003 Ski Nautique 206 Limited Previous 2001 Ski Nautique Open Bow 1994 Ski Nautique Open Bow Aqua skiing, ergo sum |

JQ likes to spend money..............his and yours  If you've found a marine LH distributor for a 351w, then the only thing needed to convert it for a RH engine is the gear. Everything else is the same. If your old gear is still good, you can remove it from the old shaft and put it on the replacement distributor. The Mallory shaft takes a .531 inch ID gear so you want whatever you might be thinking of buying to have the same shaft size. A Mallory or Prestolite for a 351W have the same shaft size, but something like a Pertronix distributor for a 351W has a .500 inch shaft and AAA marine , who you referenced may or may not have a .500 inch gear in stock. You should check the depth of the gear when installing it, you can find info on installing a 351W gear on the internet or ask here and you'll get pointed in the right direction I guess what you do depends on how much you want to spend

Thanks for the prompt reply sorry for my delay, busy day. I had read about the DUI distributors and it is definitely an option. Definitely burn a whole in my pocket. I am still hoping to salvage my old distributor or find older one and change the gears. Always a problem when buying used...you never know what your getting. Thanks Ike |

Gary, I have looked on eBay and have found several. I also have an outlet for a new Mallory at not a terrible price. Thanks for your suggestions. Ike |

Pete, This distributor is designed that the rotor and cam can be moved to any position. The clamp that holds it in place is broken and I can not find a replacement parts. I tried brazing the shaft to the advancement plate and that opened another whole can of worms. I am still trying to repair this one but looking at options, just in case I can’t. Thanks, Ike PS. I have been on this site for a long time but have never contributed. Can you give me an idea of the average/ normal amount should be. Thanks again |

Keno, Thanks for your reply. I have looked on EBay as Gary suggested and have found several LH rotation distributors. I also have talked to someone at AAA Marine and was told they do not a .531 dia. Gear in stock. Would you have any other source(s) as to where I might the gear needed. I also have looked on the internet and found very good installation instructions for the new gear. I have looked into JQ’s suggestion do the DUI unit but it is very pricey. I guess sometimes you need to add up the cost of buying used distributor, plus the gear and what others thing arise to add to cost, you could end in same price range. I would like to stay with the points ... Call me the old fart but points have always served me well. Thanks again Ike |

OK, I'll call you an old fart So with that said, it probably takes another old fart to figure out what parts you need. Here's a picture of the advance plate and the clip that I think you're talking about, along with the points cam. I don't have the hollow shaft that the cam mounts to , but maybe yours is still OK or salvageable. Let me know if these parts would be of any use to you. I don't think you'll argue with the super low clearance price  it's a freebie, just let me know |

Keno You have the exact plate the clamp is a little different but work the same. I have the shaft fixed to the plate and tomorrow will put the cam on hope I get it in the right position . Wish I had posted earlier would have save a lot of headache. All I needed was that little clamp. Thought a spot of brass would the job instead the heat cook the adhesive on the cam and would not adhere to the shaft. Thanks for all your help |

| I have a composite gear for the ford 302 (.467 shaft). If you are interested, I can open one up to .531. I believe that would be the same gear. KENO can correct me if I am wrong. |

Nothing to correct And Chessie..............the parts are your's if you want them. The cam is usually just a press fit on the shaft on a Mallory of that vintage. It takes a small puller to get the cam off and it presses back on |

Keno I think that there is not specific place that the cam goes on the shaft. On this one it seems when I heated the shaft there was material that came from the shaft. The cam just slides onto the shaft not loose but also not requiring pressing. I plan on putting locktite retaining compound but want to make sure I get the cam into the right [position, I have searched the web with no luck. Can you or someone help on this question. Ike  Keno I will PM you |

Hi Chessie Got the PM There's not really a specific place for the cam to go on to the shaft but the cam and shaft assembly which can rotate in the center hole of the plate need to be locked down with the tab so that when the points are open the rotor is pointing at the terminals inside the distributor. You don't want the points to open and have the spark trying to go to two terminals at the same time which it would do if the rotor was pointed in between terminals. The easiest way to do this is with the cap on the distributor draw a line with a Sharpie etc on the body of the distributor under the center of each plug terminal. Then take the cap off and with the cam clamped in place and the points installed, rotate the shaft till the points are open and see if the rotor tip is pointing at one of the lines. If it is you're good If not then you loosen the clamp and rotate the cam assembly to where the rotor tip is pointing at a terminal with the points open. Kinda hard to explain and may take some trial and error. It's a bit of a pain because you have to remove the points plate to get at the clamp. Here are a couple of pictures to maybe help The top picture shows the markings on the body under each terminal Second picture shows the points just starting to open and the rotor pointing at one of the marks. Extra stuff like the condenser and wires were removed just to show the rotor tip and markings more clearly. These pictures were of a same era Mallory that I've never adjusted from where it was set.. Most distributors like a marine Prestolite for example don't have this adjustment capability. Some people would say it's a fine tuning feature while others would say it's just one more way for somebody to screw up their distributor if they're not sure what they're doing

Hi, I just read your post, and while I can't answer your post, I have a very similar issue and maybe someone can help me. I have a 1973 CC Nautique that has a 351W Ford (Palmer Marine Conversion) and has a Mallery Distributer YL555DV. This engine has Reverse Rotation. I need a new distributer. Does anyone know where I can look for a replacement?

Sorry it took me too long to reply. I gave my '73 Nautique to my son many years ago. He has used his mechanic to work on the boat engine (I think he's good). We have put a new carb, new plugs, and new points in. The mechanic says the distributor rotor cap easiiy turns 360' when holding the gear shaft from turning. Bad shaft? The boat runs OK to 20-25 mph, but misses badly trying to go faster.

d*ck, Could be a simple as a sheared pin holding the gear to the shaft? Maybe he could tell you more? If not, I'd certainly get someone else to take a look at it before condeming the distributor.

d*ck On your Mallory there's a fork that screws to the advance plate and keeps the points cam in position on the plate. if he's spinning the rotor 360 degrees he's either Hulk Hogan or the fork is loose. It's hard to visualize and harder to explain. I could post some pictures tomorrow if you want. It sounds like he's doing this while the distributor is out of the engine and the movement will have the timing all screwed up if he tries to just randomly position the cam and tighten the fork unless he gets real lucky. It also sounds like a new coil would be worth trying. |

And I missed the new carb too.  Sounds like Hulk Hogan likes to just through parts at a problem?d*ck, Seriously, is there someone else that can look at the problem? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I'm having a problem posting my replies since they are not going through, but I'll try again. Re the gear being loose from the shaft; that's not a problem. I have convinced myself to get a new distributor, but having a problem finding the correct one. I went to summitracing.com . My Mallory is YL 555DV for a 1972 Ford 351W. There seem to be several, including an inexpensive one, Proform Pro-66983B for only $144.99, which sounds too cheap. There are others, but don't know what is correct. My Mallory has a gear shaft of .531 and a shaft size about 1 1/2" where it fits into the header. |

  Here are the 2 pictures
Top one shows the fork that holds the cam to prevent it from rotating in the center hole removed and the cam can rotate 360 degrees with some force applied to it. Second one has the fork in place and tightened down so it won't move in the center hole..............unless you turn it too hard, then it'll move Hope this helps
