1150 starter not disengaging

[Brendan W]

Maybe not relevant but I have about 60 - 80 thou axial float on the SC ring gear. Wondered if that was normal as the washers either side of the pinion were missing - replaced now. No hijack, just sharing

Years ago I made the mistake of using washers on the idle gear, having previously owned an 80 1100ET, when in fact the 1150 does not require them.

An aside I did not mention yet, is a ring mark on the inside of the rotor, as if the narrowest part of the tapered end is planted firmly against the inside of the rotor. Also, when the rotor nut is tightened, a thread or two is showing out the end, past the nut.

Blower, I spun the SC gear with idle gear removed. Turns freely clockwise, locks anti-clockwise. Torqued rotor back on, can still turn the SC gear with big teeth on idle gear. Don't mind all the bare case spots, those are from previous SC woes. Also, I take back the claim of a ring on inside of rotor, it was just some "gook" (Fletch). Here are a few shots

[Carter Turk]

One more.

Are you running an 1100 starter with an 1100 idler gear? Idler gears are different for the 1150-1100
Does the starter move smoothly?
Terry wants you to turn the idler gear and see if it turns the SC smoothly in one direction. I would remove the starter for this test.

Did you eat your previous starter with the explosion? Is the starter new or used?

[Carter Turk]

Ok. All appears to be good now, for whatever reason? I did Terry's test with rotor loaded, spins one way smoothly.

I changed the roller bearing to another one I had, exactly the same by the way and put may 1250 in/lbs on the rotor nut. It fired up, no hanging up.

Thanks for the support. Spent the last few hours breaking her in, all seem well and good, no leaks, with about 30 miles on the clock.

That's good news!

Good news! You'll going to love the 1229!

[Carter Turk]

Charlie, Bill, thanks for the well wishes. The starter motor is old, maybe bought it from Rapid Ray 5-8 years ago. I have an older one where most of the teeth were bitten off from SC snatching, I guess due to the shot taper on the left end. I did loose a small tooth on the idle gear yesterday. I do love the 1229, had one for the last 15 years. .25 less compression, which maybe better, who knows. No oversize valves or anything, but still noticably more grunty than the stock ES.

Just for clarity, I was referring to the 850. I haven't pulled the clutch so can't tell if anything is missing and neither can I find a specified end float for the SC ring gear.
