Removing starter, GS400EZ

[Runeight]

Save yourself the work and order one up.

OK, rebuilt the starter. I must admit, it was quite the job. The brush plate has to line up to allow the long bolts to pass thru it. Magnet doesn?t help.

Installed the tensioner and adjusted.

Hooked everything up and no go. Starter is mounted correctly allowing the bolts to line up. Starter just spins, does not turn engine over. Stumped for now, need to step away until tomorrow.

Any ideas? TIA.

Is it spinning the right way? Dont know if you can wire it so it does but hey Im just asking. The starter clutch will only engage the crank going in one direction so IF, by any chance, its turning wrong the clutch wont engage.

Chuck,

I read your post a half hour ago and it got me thinking. Starter is pretty straight forward. I even bench tested but for the life of me it sounds like it might be spinning backwards. How? I asked myself.

Well, if the armature casing is on backwards what would it do? Spin backwards. Thoughts? Everything else is straight forward.

Only thing that makes sense. Boy, it was a lot of work to do over. Live and learn, even at my age.

Before you rip it open, the starter clutch engages when it is turned counter clockwise. SO, the idler gear has to turn clockwise..which in turn means the splines on the starter motor have to turn counter clockwise if your looking at the shaft end of the starter motor.

 

[Runeight]

Agreed. Since a starter is DC only if the armature case was put on backwards it makes sense the motor would spin in the wrong direction. I remember the position of the case but might have installed it wrong. I was multitasking at the time.

Apart it comes. I?ll check rotation before disassembled.

Starter spins CCW.

Gear inside case using finger spins freely CW. Does not spin CCW.

Starter should spin CW not CCW. Armature case must be reversed. I?m a gonna take a look see.

 

[chuck hahn]

Yes as far as I recall it should be counter clockwise looking at the front end. If it spins CCW it will turn the idler gear CW.. which in turn should spin the starter clutch CCW and engage the crank.

 

[Runeight]

Armature case reversed, still spins CCW. This should be correct because the start gear in the case needs to spin CCW.

Im actually stumped. Only other thing changed is the starter solenoid which either works or it doesn?t.

Well then short across the starter selinoid posts with a creating a direct hot to the starter. If that works replace the nstarter selinoid.

 

[chuck hahn]

Does it click when you hit the start button? Is the yellow wire hooked up???

 

[Runeight]

Yes, but I?ll check again.

Both work as intended. Stumped.

Thanks for the help so far. The armature case was upside down however the starter still turns the same way. All I can do is assemble and try again.

Cant do that Chuck. Cam tensioner removed.

 

[Runeight]

Thinking a little more the starter has to turn clockwise. Only other thing is the brush plate is upside down. Can?t think of anything else. I?ll look at the pictures I took.

 

[chuck hahn]

You can remove the lead FROM the selinoid that leads TO the starter to test if the pressing of the button triggers the selinoid or not.

Bingo Baby! CW.

If you get into your starter take pictures. So....

The brush plate can only go one way. Manual shows different. It’s wrong, can’t go that way. Make certain the tab on the plate is lined up with the tab in end cap. This lines up the long screws.

The armature case is the key. If it’s off spins CCW. You have to line the indents of the case with the magnets. See pic on bottom of starter.

I did some searching and read where this will happen if it’s off. Make marks, take pictures. I’m pretty good with starter repair. Four times total. Please, don’t send me yours.

 

[chuck hahn]

CW as in from the rear of the motor? In other words, if you are looking straight at the spline side it runs CCW right?

 

[Runeight]

Right now the starter spins CW. Had it CCW.

Looking at the pic you can see the gear. This gear spins freely CW. Has resistance CCW.

I had it CCW and it just spun. Parayliss by analysis.

 

[Runeight]

When the starter spins CW it drives the gear in the case CCW thus turning motor over.

Please tell me I’m not crazy.
