SRX Remanufactured Delco Remy 39MT Starter, 12V, 12-Tooth

Description

SRX remanufactured planetary gear-reduction starter using the Delco Remy 39MT design. Supplied 121-019-0234 configuration is 12V with a 12-tooth pinion, clockwise rotation, rotatable mounting, integrated magnetic switch and overcrank protection.

Confirm the original starter number, ring gear, drain orientation and electrical connections before selection. The 8200434 application is restricted to 2015-or-older Detroit DD13, DD15 and DD16 engines with a 160-tooth ring gear and is not suitable for solenoid-down installations. Other 12-tooth 39MT references must be checked separately; engine model or tooth count alone does not establish interchangeability.
