OEM and Search References

• Primary John Deere reference: AM133646, and the plate on the old motor is the first thing to match it against, since this is the size of unit people mix up

• The Kawasaki side of the cross list runs 21163-7004, 21163-7015 and 21163-7027, three revisions of one motor fitted to FH-series petrol engines in several chassis

• Kubota bought the same assembly as EG371-63010 and EG371-63011 for the mowers it builds with a Kawasaki engine, the ZG222, ZG227 and ZG327 among them

• Denso and trade references: 228000-9260, 228000-9263, DSN2141, 410-52114, SND0516 and AS-PL S6526S, all describing the same direct-drive assembly

• Ratings: 12 V, 0.8 kW, 9 teeth, CCW, direct drive, 28.8 mm pinion diameter and 3.41 kg, with some American aftermarket stock sold as 0.6 kW or 0.8 HP

• Fitment verified on TractorData: Z-Trak 737 2002-2007, Z-Trak 757 2002-2004 and X465 2002-2005, all on Kawasaki FH-series engines
• Also seen on: the Gator TH 6x4 and the Kubota ZG222, ZG227 and ZG327 with Kawasaki engines, none of them carrying a confirmed year range

Fitment and Purchase Checks

Most listings leave rotation out, which is how a clockwise starter of the same size and tooth count ends up in the bolt holes of a machine that wants the opposite, cranking backwards while a fitter blames the battery and works out the real cause an hour later.

The power figure needs care as well: Denso and AS-PL both publish 0.8 kW, while some American aftermarket stock sells the same motor as 0.6 kW or 0.8 HP, so a lower number on the label is not automatically a different part. Beyond those three Deere models the unit turns up on the Gator TH 6x4 and on Kubota's ZG222, ZG227 and ZG327 with Kawasaki engines, years unconfirmed wherever you look, so the machine in front of you beats any listing.
