New 108 is home.

Dustin, you can check the s/g without mounting to see if they will spin..ground to case pos. to "s" ..maybe s doesn't show so NOT to field...if good should spin..lots of grass says there is probably a huge mouse nest in shroud and flywheel....j19 very common plug

Every one is going nuts, and chanting; pull the head, pull the head, pull the head.

 

[Dustin Wilson]

Haha, soon. Motor and s/g pic. Just replaced fuel line and plug.

Hey guys, I noticed someone cut the wire that the arrow is pointing to. Any idea what that wire could be for?

 

[mgwin]

Looks like maybe the wire that goes to the coil.

 

[lpalma]

The black wire goes to the coil, they did away with the Gen wire at the A terminal and moved it to the starter side of the solenoid. That other thing is a nubble at the end of the wire harness loom, a nubble.

 

[Dustin Wilson]

Can anyone tell me how to hook up the wires to the starter/generator? One terminal on the S/G reads "F" and I don't see any other markings. Sorry for my ignorance.

Doug beat me to it.

If you want to know, F stands for field. A stands for Armature.

 

[gary noblit]

Dustin, track the wire back to reg. that goes on field (f)..the other is obvious....I still suggest you try s/g before mounting ..see previous mess...the dia. shows the other post as "a", I've also see "S" and some have no mark..

I'm glad you suggested this. It doesn't spin when hooked up to a battery .

 

[Dustin Wilson]

This s/g is in terrible shape. Hopefully, I can salvage some parts from the other one I got as part of the purchase.

 

[gary noblit]

Dustin, don't trash it ..the armature and fields might be good ..Try to find a starter repair shop to get an estimate of rebuild.Have to admit brush holders looking gone... but new is around 200...Any friends have an old cub you could borrow one from to test engine...don't follow my example ,bought one ,put it on and spent 30 mins before I figured it was going opposite direction needed...

 

[hydroharry]

Dustin - you gotta have it grounded when you test it. You can't just have it laying on a bench and touch the positive to the A terminal to see if it spins. Hopefully you're other one will work.

 

[Dustin Wilson]

Well, the other one does work, but the frame is too short. I may try to switch the interior bits to the correct sized s/g.

 

[lpalma]

I do not think that will work, does the other turn anti clockwise?

 

[gary noblit]

The shorter frame one might work for testing..If you cut a 3/4 pipe exact length of space and run threaded rod thru to hold it ..I wouldn't consider running it that way but you're "testing"...If you have upper adj. arm it should hold enough to crank over

Looks lIke the brushes are missing. Check the armature for contInuity. If the armature is good you should be able to cleanup and rebuild the s/g. CC Specialties has the brushes and other parts to rebuild the s/g.

 

[Dustin Wilson]

Okay, thanks. I transferred the good brushes over from the extra s/g (they are in excellent condition) and sanded the armature last night, but I'm getting only sparks when I connect it to a battery. The springs are in great shape and bearings are free. This seems like a pretty simple system, so I'm really unsure as to why it won't spin.

 

[Dustin Wilson]

She now spins! I covered some exposed wire that goes to one of the brushes with electrical tape. It had been touching one of the two long bolt that keeps the units together. Then I moved the wire to stay away from the bolt. Finally, I moved the brushes a little bit. Will attempt to start the tractor at some point today if all goes well. Thanks for the help!
