800 special starter

[zeke83 2]

Something must have happened to my selonoid from sitting during the winter, so until I had time to work on it, I used a jumper cable to go from the battery directly to the starter.

 

This worked fine twice, but this week I had a problem. I started it up with the jumper and mowed for a half hour, then went to eat dinner. I came back out to start again but I could not get the starter to turn over. I hooked the cables up to my truck battery, and I still would not turn over.

 

I turned the motor over by hand to make sure nothing was stuck. When jumping from the truck I did have the negative cable hooked to the battery so the circuit was complete and should have worked.

 

Any ideas?

 

I did try and tap on the starter housing with a hammer

This model did not originally have a solenoid. Has one been added?

 

This B&S has a starter/generator for those that are not familiar with them.

Yeah the solenoid does not appear to be an oem part

 

Would there be any reason that the starter would not turn over when putting a jumper on it??

Bad starter

Starter brushes could be bad

Time to open her up and do some exploritory

Be careful with the hammer. A guy brought a starter over for me to repair and the magnet had broken up and jammed the starter up. Obviously someone was hitting it with a hammer.

The starter is a Delco-Remy

model 1101695

SN OK21

 

Any new aftermarket replacements for this??

 

Thanks

Another thing I noticed was when I used a pair of jumper cables on the starter, they would get real hot quickly and start to weld/stick to the positive terminal.

 

I get a tiny bit of movment of the motor when I do this

[WH nut 553]

Open the starter up for a look see, you have something going on in there. Its drawing way to much juice

[zeke83 2]

I hope to dig into it tonight

 

Where can I find replacement parts...all I can find is that the starter is obsolete...or a NOS for $250!!

Well I finally got around to taking apart the starter. Everything looked fine with nothing broken. I blew it out with air, and cleaned up what I could with some sand paper then sparyed electrical cleaner on everything.

 

The brushes looked fine, so I put it all back together and mounted it back in the tractor. I cleaned up all the exterior connections, then tried to use it with the belt not connected.

 

I used jumper cables from my truck, as the battery on the tractor was weak. The pully would spin slow, and I could stop it with my hand. The jumper cable would also get very hot, and almost start to weld itself to the terminal on the starter.

 

What could be wrong??

 

Thanks

This old Kohler manual

has a good section on the starter/generator.

 

Any long established automotive electrical repair shop will be very familiar with these. Every GM had a similar unit up till about 1962-64.

zeke,

the armature probably has some shorted segments 

the armature can no longer produce the proper electrical "cadence" to keep the armature spinning

 

if the armature windings look more blackish than copper colored, have the armature "growled" at the repair shop.

[WH nut 553]

If you cant find a shop with a growler, you can use an Ohm meter and check each segment of the commutator from segment to ground(shaft)

send me a PM, I think I have one of these starters in stock, but it might be a day or 2 before I can look my Daughter is graduating this weekend and we are very busy.
