What does the 42MT mean for a starter?

What does the 42MT mean for a starter?

The 42MT is a straight drive starter for heavy duty applications available in 12 volt and 24 volt configurations. The 42MT features a Semi Solid Link solenoid and optional Over-Crank Protection.

What is the spacer for on a starter?

In some applications, the housing may require the use of an OE-provided spacer that comes with the engine. It is designed to ensure proper clearance between the starter pinion and the engine ring gear. During removal of the starter, it’s not uncommon for the OE spacer to stick to the old starter.

The Latest 2017 May Tech Tip: Understanding Starter Motor Mounting.

Are direct drive and gear reduction starters interchangeable?

A gear reduction starter may appear different by design. For example, the Delco Remy 29MT™, 35MT™, 38MT™and 39MT™ all incorporate a nose-less design and don’t include a cone around the starter drive. Despite this design difference, these starters are completely interchangeable with straight drive nose style starters.

What is a disadvantage of the 42mt starter?

When the cranking circuit is energized in sub-zero conditions, the engine turns over slowly and unevenly. Which of the following is a disadvantage of a 42 MT starter motor? heavy. When performing voltage drop testing through the ground circuit of a starter motor you record a voltage loss of 0.6 V-DC.

What does Overcrank protection mean?

OCP technology is a built-in circuit breaker that protects the starter from thermal damage and automatically resets at a safe operating temperature. OCP protects the starter in adverse starting conditions, such as cold weather cranking, lower battery capacity, high-starting circuit resistance, or operator misuse.

What should be done before beginning a starter replacement?

How to Replace a Starter

  1. Safety First. Disconnect the battery.
  2. Remove the Wiring. Remove the wiring and positive battery cable from the starter solenoid.
  3. Remove the Starter and Bolts. Remove the starter retaining bolts.
  4. Compare to Verify.
  5. Transfer Heat Shield.
  6. Replace with New Starter.
  7. Secure and Tighten.
  8. Connect the Wiring.

Does a gear reduction starter spin faster?

Unlike direct drive, gear reduction starters use smaller, faster motors to rotate their pinion gears in a roughly 4:1 ratio, which results in lower power consumption and higher torque.
