What is distributor gear material?

What is distributor gear material?

Distributor Gear Materials:

• Cast Iron.
• Composite (offers great life, conforms well to the mating cam gear, and is compatible with ANY camshaft gear material)
• Melonized or hardened steel. (material that OEMs use with factory roller cams; many aftermarket.
• Bronze (conforms well to the mating.

  Do MSD distributors come with Melonized gears?

  The melonized gear is still available from GM and ACDelco. Fortunately MSD now sells a melonized gear for 0.500-inch shaft Chevy distributors (MSD PN 8531).

  What do you need to know about gear inspection?

  The composite test of a gear is a method of inspection in which the work gear is rolled in tight double flank contact with a master gear. AGMA defines this type of inspection as “radial composite deviation.” No backlash is provided, as the work gear is spring-loaded against the reference gear on the inspection machine.

  What should I look for after removing a distributor?

  Once the distributor is removed, look at the drive gear on the bottom of the distributor shaft. It should not be loose or appear to have any significant wear or chips missing in the gear. The distributor shaft should spin freely without significant play.

  Why do I need to position the distributor rotor?

  Due to the distributor and camshaft gears being helically cut (cut at an angle), you will need to position the rotor approximately 30 degrees one way or the other as the gears will cause the distributor shaft to turn slightly as you engage the gears together.

  When do I need to remove an ignition distributor?

  A distributor may need to be removed from an engine as part of a repair procedure or require replacement due to a mechanical problem such as a worn distributor gear or broken distributor shaft. In this guide, we will cover the steps required to remove, replace and retime the ignition distributor.

  How can you tell if your car has a faulty distributor?

  The current will short out if the electrical connection is grounded. If the condenser is open, it is due to a broken wire lead. This causes point arcing and burn, which will stall out the engine. Take a look at the contact points.

  What’s the best way to install a performance distributor?

  (1) Drill a .030″ hole in the lifter/oil galley plug behind the distributor. This will allow additional lubrication on the distributor and cam gears. (2) Install a deeper oil pan. High volume pumps will pull all of the oil out of a stock pan creating a lack of lubrication. (3) Ford oil pump mounting brackets have elongated holes.

  Why is the distributor not aligned with the oil pump shaft?

  (3) Ford oil pump mounting brackets have elongated holes. Due to this, the distributor shaft and oil pump shaft should be aligned so that the distributor turns freely before tightening the mounting bracket bolts. Failure to do this will cause a binding situation, thus damaging the gear.

  Can a DUI distributor be installed into an ignition system?

  If you are installing a DUI distributor into an engine that has an ignition system presently, then this simple procedure will have your engine running in no time. On the old distributor, remove the distributor cap and the vacuum advance hose. Note the position of the rotor.
