SPM-HEP-4260 is the 12 volt starter motor with 9 tooth pinion, solenoid and mounting flange. It is used on Kubota V3307 engines. 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 Kubota 1G524-63011 and Denso 428000-4860.
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.
