The Alliant Power AP52907 is a remanufactured Denso-design common-rail fuel injector for John Deere 4045 (4.5L) and 6068 (6.8L) engines. It replaces Denso 095000-0590 and John Deere RE545562, RE543351 and SE502671. Listed machines include 5085E, 6140R, 6150R, 6170R, 6210R and 7200R tractors, 210G LC and 250G LC excavators, 524K, 624K and 644K wheel loaders, and 700K and 750K crawler dozers.

The 4045 and 6068 used several Denso injectors that look alike. AP52907 is not the same part as AP52902 (Denso 095000-6310) or AP52903 (Denso 095000-6320), and it takes a different install kit (Alliant Power AP0124, sold separately). Worn injectors show up as hard starts, rough running, smoke, low power and fault codes. Each injector comes with its trim code, which must be programmed into the engine controller.

Frequently Asked Questions

Will the AP52907 fit a John Deere 6140R or a 210G LC?

AP52907 is listed for John Deere 4045 (4.5L) and 6068 (6.8L) common-rail engines that take Denso 095000-0590, and both machines are on its list. The 210G LC is also listed for AP52902, so the machine model alone is not enough. Send us the number on your old injector or the engine serial number.

What numbers does the AP52907 replace?

It replaces Denso 095000-0590 and John Deere RE545562, RE543351 and SE502671. It also replaces the older Alliant Power number AP52807.

Is AP52907 the same injector as AP52902 or AP52903?

No. AP52902 is the Denso 095000-6310 injector and AP52903 is the Denso 095000-6320 injector. They look alike, but AP52907 is a different part and takes a different install kit, Alliant Power AP0124, sold separately.

Is the AP52907 new or remanufactured, and is there a core?

It is a remanufactured Alliant Power injector. A refundable core charge is added at checkout and refunded when we receive your rebuildable core. Each injector comes with its trim code, which must be programmed into the engine controller.
