ES646238-2 HARTZELL NEW STARTER

June 1, 2021

This is the first time I have used a Hartzell rebuilt starter on a big Continental engine. It is priced right but the durability is to be determined.....

Excellent product. Previous starter sacrificed starting power for weight. The Energizer has plenty of power and does particularly well on hot starts.

Works as intended. Plenty of power! Clutch feature needed for any Continental engine works well. The engine starter adapter will thank you. This is the only starter that is a good replacement for the OEM starter.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: When purchasing the Energizer starter, is there an o-ring that needs to be purchased separately? Anything else not included?

The O-ring P/N MS9021-038 comes with new units, but not with overhauled units. Overhauled units will need to purchase a separate MS9021-038 to comply with Continental instructions.

Q: Regarding 646275-1R: What is the meaning of the suffix of R?

The R designates that it is an overhauled starter. The units without the R are new, outright.

Q: What warranty period is offered on HARTZELL overhauled and new starters?

New: 36 months or 1000 operating hours. Overhauled: 6 months or 250 operating hours.

Q: Can the return starter core be the original TCM Starter or does it have to be like-for-like (i.e. a Hartzell Energizer Starter)?

It will have to be like for like.

Q: If I order a 646238-2R overhauled starter, can I return a core that is a regular Teledyne 646238?

Yes that is an acceptable core.

Q: I understand the core charge when purchasing an overhauled starter but do not understand why it is charged on a new starter purchase. Why is there a core charge on a new starter purchase?

Hartzell put in place cores on all starters and alternators starting in 2020. This includes new models. Hartzell accepts the starter that is being replaced on the aircraft as a core for a refund of the charge.
