184 won't start

[rednax]

After a few months of having my 184 torn apart, I put it back together and went to start it. The carb was leaking but I just had to clean off the needle and seat. When I went to start it, the starter turned the engine a tiny bit and stopped. I don't think the engine's stuck and the battery's full. I put pto belts on it, which it didn't have when I was able to start it a few months ago. The pto clutch isn't wired into the electrical system and it's disengaged. I don't see anything that's blocking the engine from turning over. Has anybody else had this problem? Maybe the pto clutch pulleys are frozen?
Thanks

Loosen the PTO tensioner pulley so that the belts can slip. I use a 3/4" box end wrench and slip the belts off the tensioner pulley toward the front of the tractor. It is tight but they will slip by the pulley and get loose. Once loose, try again. Might also want to check the fan and alternator to make sure those are free as well.

I slipped the pto belts off and the engine cranked over. It looks like the pto clutch pulley is locked up. I'll put some pb blaster on the pulley. If it doesn't work I can bring it to a place that rebuilds starters and similar stuff that my neighbor told me about.

Before you have the starter rebuilt.

Clean up all battery cable connections. Check cables for internal corrosion. Move the battery ground cable from the sheet metal to the transmission/differential case.

Hi,
The Cub 184 LoBoy operator's manual can help you learn about maintenance that the Cub 184 LoBoy needs.

Below is the Cub 184 LoBoy operator's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 1.
It shows how Cub 184 LoBoys originally looked in it. The lube section begins on page 48.
It tells how to use the light switch on page 9.

If the red or the white rear light won't come on, and the wiring is good, the sealed beam or the bulb might be burned out, or the light might have a bad ground.

Before going too far into the electric PTO, disconnect anything connected to the PTO (perhaps a mower deck) and see if you can turn the PTO. Perhaps a mower deck spindle is locked up.
Also, one of the PTO bearings in the rear of the tractor might be seized. Those are easier to change than the electric PTO. More investigation is required before having expensive things rebuilt.

Note: If the 3 bolts on the electric PTO are "overtightened" then it won't ever turn off the PTO. These are spring loaded and there is a happy medium where the electric PTO functions properly. Count the bolt threads that are exposed before you adjust. That way you can put it back if you want. All 3 should have the same number of threads exposed.

Regarding the rear combination light, the dim and bright setting should illuminate red (a clear tail light bulb with a red lens) and the Rear setting should illuminate the bright white light.

The front and rear lights don't switch on, and some stuff on the dash was bypassed, but most of the wiring is original. Maybe I'll leave the wires that go to the right places and rewire the rest. When I had the belts on it and it wouldn't start, the pto was disengaged (I could turn the pto shaft without the pto pulley turning) and I tried starting the engine with the pto brake plate removed.

Check the fuse (and the fuse holder) There is a fuse holder on the dash. One is for the lights and one is for the PTO. Remove the fuse and clean inside the fuse holder (and the cap) with a dremel and a small brush. Coat the fuse ends with di-electric grease.

These fuse holders are not water resistant and they don't like to get wet. I also coated the outside of the cap with di-electric grease hoping that will seal a little bit and keep water out. Lights should work regardless of the key position.

For the PTO, you should be able to turn on and off the PTO when the key is in the run position. (Don't leave the key in run position too long without engine running as this may damage your points) So turn the key on and toggle the PTO switch on and off. As you turn the switch on and off, you should hear the PTO engage with a clunk to engage and a click to disengage.

If engine is off, turn the PTO by hand. When the PTO is engaged, you should see the PTO pulley turn. When the PTO is disengaged, the PTO pulley should not turn.

I cleaned out the fuse holder for the headlights and they lit up. There was a little bit of corrosion, probably because the guy who I bought it from left it uncovered outside. The rear light doesn't turn red or white, but some wires are cut. The pto wires aren't hooked up and the connector for it was probably cut off. The pto is disengaged. There's no spark but I've got an ignition tune up kit. Thanks for your help.

Old post but for future reference to whoever has this problem, if you know the battery is good and the solenoid doesn't click check the pto switch for corrosion and wear. If the pto switch is bad it cuts all power to the starter

I found the problem with my electric clutch. I bought the tractor in September of last year for dirt cheap so I'm find with fixing it. Is it possible to replace only the part with the copper windings?

The electric PTO is a pretty expensive part. HamiltonBobsCubs has new ones (and probably a few used parts if you call them).
