SPM-HEP-4246 is the 24 volt gear reduction starter motor with 11 tooth pinion, solenoid and harness. It is used on Isuzu 6HK1 engines in Hitachi ZX330 excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
It replaces Isuzu 1-81100-324-0 and Nikko 0-24000-3041.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Slow or no cranking
With good batteries and cables, a starter that turns slowly or only clicks is worn.
Grinding on engagement
Worn pinion or flywheel teeth grind on start. Check the ring gear when fitting a new starter.
Intermittent starting
Worn brushes and solenoid contacts make starting hit and miss.
Fleet spares
A spare starter keeps a machine working while the old one is rebuilt or scrapped.
