The 6598 starter motor is identified by 10T pinion, 32 mm pinion OD, and 82.5 mm engagement with a 3-terminal solenoid. Many wrong orders happen when buyers match "10T" but ignore OD and engagement.
Not safely. A 40 mm OD 10T unit can change engagement behavior and cause grinding or poor meshing. For 6598 applications, match 32 mm OD + 82.5 mm engagement.
Typical reasons: wrong engagement geometry (OD/engagement), worn ring gear, or mount misalignment. If grinding existed before replacement, inspect the ring gear to prevent repeat failures.
It indicates the pinion travel. If engagement is too long/short, the pinion may not mesh correctly, causing noise or damage—critical in fleet and military service.
Many 24V systems and fleet harnesses are built for a 3-terminal layout. Substituting a different solenoid type can cause no-crank or wiring rework—confirm terminals before ordering.
Often due to battery imbalance (two 12V batteries), corroded grounds, or voltage drop. Measure voltage at the starter during cranking to separate electrical vs starter issues.
Cold reduces battery output and increases engine load. If one battery in the 24V pair is weak, the 6598 starter may crank slowly even if the motor is good.
Heat and vibration loosen terminals and degrade grounds. Intermittent no-crank complaints are often caused by wiring resistance rather than motor failure.
Yes. A damaged ring gear can grind and damage even a new starter drive. Ring gear inspection is recommended if failures repeat.
Provide 6598 reference, confirm 10T, and verify 32 mm OD + 82.5 mm engagement, plus a photo of the 3-terminal solenoid.
