Q&A

Q: What is the difference between ES4000 and ES4000LS alternators?

Per the manufacturer, ES4000LS is without the pulley, ES4000 is with the pulley.

Q: On an ES4000 Hartzell alternator, what is the alternator mounting through bolt size? 7/16 seems very loose, but 1/2 is no go.

The mount boss hole is typically .440 - .445 inch diameter. A 7/16 bolt is .4375 which would be the correct size. However, it is not a "tight" fit.

Q: what alternator you would recommend to replace my Continental Motor, Part number 646845, MFG NO 014LA021, 24 volts, 60 amps ?

We have this part listed under our part number 07-08843.
