Description
Delco Remy 8201084 is a Genuine Delco Remy OEM 38MT+ starter motor with Integrated Over-Crank Protection (IOCP) engineered for Paccar MX-11 and MX-13 engines in Kenworth and Peterbilt heavy-duty trucks. The IOCP electronics shut the starter down if cranking exceeds safe duration, eliminating the external over-crank harness needed on the prior 8200977. This 12V, 4.6 kW SAE 3-mount unit uses electrical soft-start and an integral magnetic switch (IMS) for reliable engagement in cold weather.
Signs You Need a New Starter
- Slow or sluggish cranking, especially in cold weather
- Clicking sound when turning the key with no engine turnover
- Intermittent starting failures or no response from the starter
- Grinding noise during start indicating worn pinion gear
- Starter continues running after engine starts (solenoid stuck)
- Visible damage, corrosion, or oil contamination on the starter housing
