  1. My little snowblower is also a "Montgomery Ward" unit. It's not been used in several years but I'd bet it wouldn't take much to make it operational. Rob
  2. If'n he is a supporter of the old truck hobby, I've got some work for him on a couple of Mack "AB" engine magnetos. Rob
  3. V8 Mack engine. I like it. Rob
  4. Not necessarily. When the truck is in the air supported on stands, it takes a lot less force to rotate the rears than everything as in actual operation. Pushing the truck through the friction of the tires rolling, and overcoming the resistance of the air takes a lot of power right off the top. If you can, adjust the rear brakes to drag pretty good while you accelerate with the wheels on stands to load the driveline.You should be able to start off in the same gear you experience the vibration in or the brakes are too tight.

  5. she has reduced. Rob
  6. 1934 is the copyright date of the advertisement. Rob
  7. Remember catalog shopping? Rob
  8. Ya'll seen Ms. Bach lately. She don't look much like "Daisy Duke" no more. Rob
  9. Will do, thanks! Rob
  10. Honest mechanic shops are few and far between. A good portion of mechanics are "box swappers" and in some cases need to be as subassemblies are no longer available. Rob
  11. Any idea as to why that would help? Those little "squish" plates are actually the check valves in the delivery valves. If they don't seal as imperfections cause, a portion of the fuel contained within the plunger barrel awaiting next injection cycle is allowed to bleed back into the fuel gallery within the injection pump and return to tank. The plunger upon traveling up the bore of the barrel has to make up this lost volume of trapped fuel and replenish prior to the building pressure within the barrel overcoming the spring pressure of the fuel injector that allows injection. The long and short is too little fuel volume is injected. This is why the power is down, smoke is down, and turbo boost is lacking. \ Those check discs and the springs are renewed at rebuild time. I've seen far too many pumps rebuilt due to these valves being bad. Pisses me off that so many shops whosale replace everything in a pump instead of controlling the costs by replacing only what is defective. Rob
  12. If certain the problem is speed related there would need to be some rotating mass out of parameter. This would not dissappear at differing speeds. However, a bind, (as in a bad universal joint) would, and could set up a vibration as a harmonic of the original and those are even in symptoms and multiples of the same symptom. I'd dissassemble the driveline to and evaluate along with the carrier bearing, (if there is one) for any rotational binding. Rob
  13. I'm up against the same roadblock there. One other note is make sure the drive yoke pinion nut is tight and cotter pinned on the rear of the trans. I've seen those loose with Nylock nuts and they do strange things in the driveline. Have you had the driveshafts out? I've seen brinneling to the bearing surfaces and it acts strange also. On a final note; have you always been in the same gear at the same engine rpm when you notice the vibration? If so, change something either up or down to evaluate. Rob
  14. Fashion a platform to strap a chair to, or yourself to and look around while someone else drives. Rob
  15. My 72, 77, and 78 R models have that style. I plan to use the 72 spiders on my 58 B model as a drag winch truck with four spring brakes also. Rob
  16. I didn't realize you had the "thick" castings. No, they won't fit as shown. It can be worked with however. Would you be interested in four of the offsetting brackets if I have some made? It would keep the cost down to have more than just a few laser cut. You would then be able to run an offset slack adjuster and add spring brakes. When I checked last, if they layout and cut 100 of them, they drop in price quite substantially. I could bring the to the ATHS show next summer, or Lititz. Rob
  17. We don't have any of those guys around here in the rolloff business. Peoria Disposal has that market but they don't have any alarms. You will see them on the road with the rails up a bit at times. They run through a lot of employees to. Bout on par with McDonalds. Rob
  18. Donaldson only offers plastic in the aftermarket. I'm wanting a couple of steel ones to chrome. One is 16", the other a 14" if I remember correctly. They are both on R models. I know the larger one uses a 6" opening, and I'm thinking the smaller one is 5". Rob
  19. Mine is large enough it would take three of the "poster babes" here on this site to replace her. However, she don't bitch too much unless I buy another truck. Rob
  20. In a quiet truck it is easy to hear, and feel. In a noisy, and less than smooth operating environment, they burn up easily. Rob
  21. I'd think "Fruit of the Loom" cotton would be the first layer. Rob
  22. Of all the "muscle cars" I've owned through the years, my Barracuda always was, and still is my favorite. One of these days I'll summon up the motivation to get working on it again. Rob
  23. You really will like that setup once you are comfortable with it's use. Another word of advice, have an ancillary red light installed into the dash so you can tell when the PTO is engaged. I know the floor tower will have one but believe me, complacency will set it over time and you will not look at the light. If there is a red "meatball" staring you in the face, you are less likely to forget the PTO is engaged. Something else I had installed onto the carrier beds was "proof switches" to let the driver know the bed was slid all the way forward into the locks. This could be incorporated into a dump body also to ensure it is completely down, but I've never seen it myself. Rob
  24. Overworked R Model is an "Oxymoron". Rob
  25. The Ford "Talladega", although a good platform was an attempt to "catch up" late in the game, as was the "Boss 429" engine. Both Ford, and General Motors nagged and complained though the 1960's about "unfair" advantage Chrysler displayed in most phases of auto racing in those days. In my opinion this was solely achieved through sound engineering and testing in both real world existence, and the various racing programs. To this day the most powerful engines still use the hemispherical combustion chamber design as there simply is no better, or less restrictive design to move air through an engine. This design although not the Chrysler Corporations own, but was highly developed, refined, and exploited by them starting in the late 1940's through the end of the 1980's. Of course this basic design has paved the way for the small engines of today having the capability of producing horsepower unheard of 30 years ago. I remember the lightweight, and altered cars of the 1960's well. Most of these "radical" designs were of the Chrysler Corporation racing programs which at the time had considerable assets available to them. They also had the desire to win without corporate politics involved. Rob
