Sounds like you removed the rear cover instead of dismantling the starter from the gear side- good luck putting it together that way - you need to dismantle from the gear side so you can put the armature into the brushes with no prob -

Does the commutator end cap part # 12-227-11-s clamp on to your old bruches?


If you had it apart and know your brushes are good, you could just order the part specified, but if I was you I would get the part and the brush kit. The brush wire actually has an eye fitting that bolts to the cap. You might have a pinched wire or, the wires might be brittle and when you go to remove the brushes, could break apart.
For your parts, google the number along with Kohler and see if you cant get it cheaper from somewhere else. In my experience, Sears is only comparable if they stock it in store and you live near by.

Check that battery has full power Check terminals are clean and tight. If starter is old and done a lot of work check brushes for wear. If worn may need complete overhaul. Check that holding studs are tight.

How to fix 1982 xs 650 yamaha starter?


it could be your button i know this bike very well
does not matter if it is the xs 1 or the xs2 the same set up applies
there are a few components you need to test first
starter button
starter solenoid
wiring
main fuse

i will also tell you some major mods i did to one
when i was dragging the xs650 at super twins
which included a rebore to a 1056cc and having 7 gears
and a turbo

to eliminate the button
with the battery still connected
get a spanner or a screwdriver and not doing it to long
arc out the two polls on your starter solenoid
if you do not know what that looks like follow the main red wire
that goes from your battery
the first stopping point will be the starter solenoid
one poll clamps the main wire from the battery
second poll clamps the main wire to your starter motor
arc out the two polls with a spanner or a screwdriver
to test the motor
if your motor turns the engine then it is not your starter
the problem lies in either your

starter solenoid, (this is a sealed unit replace unit with a new one)
the wiring, (test main wire from your ignition to your switch
also test wire from your switch to your starter solenoid also clean all your wiring connectors)
your starter button, (strip and clean)
main fuse, (replace with a new one)

if the motor does not turn
then you will need to remove the starter motor
before you take the starter motor apart
test it with a multimeter
set on omes test each wire on the body of the starter motor starter
to check if the windings inside are earthing out on the body
if there is a reading on the multi meter
then your windings are earthing out
if there are no reading it may just need a clean up and new brushes fitted
and reassemble your ride

TRIED AND TESTED ENGINE MODS

if you play or really want to play there are a few major mods you can do that have been tried and tested

REBORE TO 1056CC GRASSTRACK MODS
parts needed
slab billet alloy 13in x 8in x 1.5in (for stroker kit)
or a pre brought stroker kit from halco tuning or wisco
get 2 mercedes benz 2.3 pistons ( for rebore)
2 barrel liners
find a good engineer and rebore your barrels and fit new sleeves
fitted with your 2.3 pistons

by fitting the stroker kit you will lose the standard top engine mount
or have more made as you by now should know a good engineer

EXTRA GEARS
remove kick starter reduction gears
find a good engineer and have 2 more gears made up
and fit

TURBO FITTING
tried and tested turbo fitting
a mk 1 land rover turbo is small
and can be fitted under the carburettors
with a heat shield fitted between the carbs and the turbo

these are all mods i have done to the xs650
i built and raced i got to 180 mph over the 1/4 mile strip
with a xs650 hardtail chop that looked like a standard engine

have fun

is this 6 or 12 volt? also is this positive ground or negative ground? if you pull the starter and put it on a bench ( lets say this is neg ground and 12 volts) put red charger clamp on the post and touch the black clamp to the casing (where it bolts up) it should turn over. things would be hooked different if its 6 volt or if its pos ground

12.5 hp mtd starter turns slowlllllly


brush's inside the starter are bad the brush's made poor contact with the armature inside the startermotor and are not getting full contact causing the armture to get hot causing the starter not to spin at rated speed to start motor you have 2 things you can do (1) take the motor off the lawn mower unit and have it rebuilt or buy a new unit and still have the old one rebuilt so you have a spair have them test it in front of you take and place it in a dry plastic bag so you have it ready for the next time it fails

No start issue on Husqvarna YTH 150


I'm assuming this is a Briggs engine? You said you dismantled the starter. Did you pull the armature out of the brush holder on the bottom? It's a bear to get the brush holder with the spring loaded brushes back on the armature. If you didn't take it off, or managed to get them back in place, hook the positive battery cable to the terminal on the starter and touch the ground the the mounting bracket. It should spin.

Have you checked the starter motor? It sounds like it is bad. You might be able to remove the blower housing cover and physically turn the starter teeth and then try to start (after putting the cover back on). If it tries to start then you have a bad starter (dead spot on the winding). Just replace the starter and you should be good.
Good luck!
