84 Spree starter gear?

[roadcapDen]

I'll check the #'s soon after I take 'er apart for the umpteenth time.

Is there supposed to be a 10mm washer on the outside of the pinion/bendix shaft?

Back to the original posting question....

piston is clean w/ new rings, tranny clean.

Any ideas?

A good starter runs no load quite quickly. Electric weedeater sound comes to mind. There's a number of items that can cause a starter to run slow, but shorted/burnt windings and brushes are two more common ones.

Your starter pinion spins out from inertia, when it hits the flywheel, the resistance of the turning the engine helps keep it out. When the engine starts, it runs faster than the starter, and rolls the pinion assy back down, out of contact with the starter drive gear.

If you have a slow starter for whatever reason, when starting the engine will resist the starter on compression, but just past TDC, especially if the engine fires weakly, can overrun the slow starter, wind the starter pinion down, leaving the motor spinning. At that point, there's really nothing to pop the starter gear out again, you have to release the starter button. Any inertial effect to get the pinion out is gone, until the starter motor is stopped. You guys out there with low batteries have probably had that happen.

Seems to be the same teeth count, but different part code.
The left crankcase part numbers differ between 84/85 and 86/87 too, that *could* be where Honda made an adjustment for the different starter pinion (bendix) gear tooth count. It's interesting to see how much part change went on on Sprees.

Re; 10/11 tooth starter motor shaft. In my earlier message, I only saw a part number difference, no confirmation other than for sure 84/85 is 10T, but the 86/87 starter did not give a tooth count. Part number difference could be for other reasons, so we still need confirmation for the 86/87 starter's.

Nice concise easy to understand explanation, Thanks!
I'll check the starter motor #'s too.

An update...
Got a new good Yuasa battery and when fully charged it will spin the starter up to 3 seconds (old battery only spinned it for about 1 revolution only) The new battery will charge up to 13.5 V but after useing it a bit it drops down to only 12.5 V and that doesn't seem enough to turn the starter much more than 1 revolution. Same with both pinions installed???
2nd bad battery???
Thanks for any responses!

Weak batteries will do that.

1) High Current Draw?
I know you checked out the starter, but its sounding like a big drain on your new and old battery when cranking. A shored coil in the starter can do that and the starter still turns, but not vary fast. If your engine has a problem that would heavily load the starter while cranking, that would worth investigating.

2) Abnormal voltage drop before starter? Bad (corroded wires), Starter Relay (bad contacts), starter electrical connections (Power/Gnd)

Thanks Guys,
I had the starter checked out by a professional, starter turns very fast.
Will keep digging?!
