H400 starter, the short version
Twelve volts. 1.1kW. Ten teeth on the pinion. Turns counter-clockwise. Sits on the 200cc single that H400 drone guys run. If four of those five match your old motor you are probably fine. If only three match, stop and read the rest of this page.
The housing
Black drawn steel can, about the size of a beer can but heavier. Nose end is a machined aluminium flange, two bolt holes, pilot spigot in the middle to centre the thing on the crankcase. Terminal stud on top with a rubber boot over it. Nothing fancy. Nothing that will rust through in a season.
Why the tooth count matters more than the photo
Nine teeth and ten teeth look identical in a thumbnail. They are not identical in a flywheel housing. The pinion has to reach the ring gear at the depth the original did, and the helix angle has to pull it in, not push it out. Order the wrong one and you get a starter that spins freely and a lot of bad words. Ten teeth, CCW. That is the number.
QD200-003
That is the number stamped on ours. It is a factory number. It does not appear in the aftermarket cross-reference books, and we looked. So there is no "replaces X, Y and Z" line on this page, because making one up would cost you a return shipment. Dig out the label on your dead unit. If a second number is printed under QD200-003, match on that one. Send us a picture if you want a second pair of eyes on it.
Before you spend money
Nine out of ten starters we get back were never the problem. Clip a meter on the battery, have someone hit the key, watch the needle. Drops under ten volts? Battery or cables. Holds twelve? Then look at the ground strap, then the relay, then the ring gear for chewed teeth. A flat battery and a burnt motor sound exactly the same from the driver's seat. Both go click.
Fitting it
Two bolts, one big stud, one small trigger wire. Disconnect the negative first. Wipe the flange face so it sits flat. Spin the pinion by hand before you bolt it down and watch it travel out and spring back. If it drags, the spigot is off or the flange is cocked. Torque the main stud properly and put the boot back over it. A slack main nut cooks the terminal in minutes.
Terms
Twenty pieces minimum. Ten to fifteen days to build and ship. RoHS, REACH and ISO9001 paperwork comes with the batch. Six month warranty, same as the rest of the catalogue. All three of those are draft terms, so confirm them with us before the order is locked.
