John Deere 7610 7710 7810 8400 Tractor Starter Motor | 12V 4.8kW 11-Tooth CW | OEM RE69704

Deere drew the 7010 line and the 8000 line in different decades for buyers with different acreage, and still the cranking fell to the same Denso gear-reduction motor, which is the short answer to why RE69704 covers so much ground. Behind the flange sits an OSGR reduction set driving an eleven-tooth pinion clockwise, on twelve volts and 4.8 kW. From flange to nose it measures 244 mm. Weight is 10.58 kg, which decides how the job gets done: on a bench, with both hands, not balanced on three bolts while somebody hunts for a socket. Deere's paperwork runs the 7610 from 1997 to 2002, the 7710 and 7810 to 2003, and the 8400 through 8520 from 1995 to 2005.

OEM and Search References

• Primary John Deere reference: RE69704, the number this listing describes and the one to hold against the plate on the old motor

• Deere's supersession chain runs through RE501294, RE501298 and RE61406 before the later numbers RE65100, RE65103 and RE70957 arrive, with SE501403, TY24439 and 2589223C91 also circulating against this unit

• Denso built the family as the 228000-4630 with the -6530 and -7870 variants following, and the same unit answers to Denso DSN2006 and the trade number 410-52074

• Twelve volts and 4.8 kW turn eleven teeth clockwise through an OSGR reduction set, the body measures 244 mm overall and the assembly weighs 10.58 kg, though a 4.0 kW badge appears on some aftermarket stock

• TractorData covers the 7610 from 1997 to 2002, the 7710 and 7810 through 2003, then the 8400 from 1995, the 8410 and 8420 from 1999 and 2002, and the 8520 until 2005

• Buyers reach it as RE69704 starter, John Deere 7610 starter motor, 7710 starter 12V, 8400 starter or Denso 228000-4630, and those strings find it in most catalogues

• Also seen on the 9650 through 9860 STS combines and the 8010 and 8020 tractors, though no source worth quoting confirms their year ranges

Fitment and Purchase Checks

Power is where this number bites, and it bites quietly. Some aftermarket stock reads 4.0 kW, and while the 228000-4630 family did run in more than one rating over the years, Deere's own figure for RE69704 is 4.8 kW, so that badge means a different variant of the family rather than a cheaper equivalent.

Then there is the reach of the number: the same motor turns up on the 9650 through 9860 STS combines and on the 8010 and 8020 tractors, with no confirmed year ranges in any source worth reading, which is reason enough not to treat one catalogue table as a verdict. Photograph the plate on the old unit, count the pinion teeth, and send both with the enquiry.
