After removing the belt from the pulley I dicovered that the pulley
spins
freely, and that it is attached to the electric clutch. How do I remove
this?
Thanks, Neal

I have a John Deere 110 riding mower with a seized B&S 11 hp
engine. I have removed 4 bolts mounting the engine to the
frame. How do I remove the pulley? I got the big bolt in the
center of the crankshaft out, but it looks like it is pressed on. Do
I need a puller? There is not a lot of room or easy access to the
underside of this area. I bought this mower at an auction over
ten years ago for under $400, so it has served me extremely
well! It is worth repairing, and I found a reconditioned 11 hp B&S
for $100. Thanks for your help. Neal

Hiya Neal
The pulley is NOT pressed on- it may be stuck tho after so many years
of
service. Liberally apply PB blaster nad let it soak, tap it with a small
hammer
(lightly) to help the blaster seep in. Once you get it to move a bit it'll
come
right off-
Lemme know how it goes !

Hey Neal-
I've never pulled an electric clutch off before. I was thinkin of a manual
clutch I believe on a 210. Anyways- there may be two setscrews (allen
wrenches) holding part of the clutch assembly to the shaft- feel around
on the sleeve for a couple of holes.
Also- give me your best description of what you see-

I looked and felt for set screws on the pulley and the clutch, but I am
fairly certain there are none. What I can see under the deck is an upper
pulley that is keyed to the crankshaft that drives the transmission. This
pulley will move up and down the crankshaft about 3/8". Below that is
the electric clutch, that looks like it consists of a triangle shaped upper
plate, bolted with springs on the three corners to the bottom part,
which looks like a deep saucer. This houses the clutch pack, which is
similar looking to a centrifugal clutch found on a mini bike or go cart,
but isn't centrifugal. I think it is an electro-magnet. Inside this
"sandwich" is a disc that is keyed or splined to the crankshaft, and the
pulley that drives the blades in the mower deck sits below that. This
pulley spins freely without the clutch being engaged, or turned on, but
when energized, attaches itself to the disc, compressing the springs
holding this pack together. There was a large grade 8 bolt going up
into the crankshaft, which I removed. Now I need to know how the
clutch assembly is removed. I have taken a picture of it with a digital
camera, and plan to show it to my friendly JD dealer for advice. By the
way, the mower is a model number 111, not 110 as I previously said.
Thanks, Neal
AnswerGot it- 111
OK- Neal the clutch pack and pulleys are supposed to just slip off the shaft, the shaft is keyed, and they are all held on by that grade 8 bolt you already pulled. However, I've been made aware that the clutches simply slipping off is seldom achieved without much cursing, pulling, tapping, application of liquid wrench etc. In a pinch I have used (with GREAT sucess) one of two sizes of ball joint drivers to remove stuff like this. The drivers are in the shape of a two pronged fork with the prongs shaped like wedges. Wonderful tools for stuck pulleys (two of those plastic wood wedges from wallyworld work well also) apply penetrating fluid, wedge the pulleys to keep force applied downward and tap the end of the crankshaft upward with a brass hammer.
lemme know & be careful!
