Starter Pinion gear not contacting flywheel correctly

9 posts in this topic

I am asking for help from all the members in Red Square. I have a Wheel Horse 520-H with an ONAN P220G-I / 10955C.

I bought a new starter motor and flywheel from my local Toro dealer whom I trust and has never steered me wrong yet. I installed the starter motor with the spacer bushing on the correct side of the engine block to get the starter motor gear out far enough to make contact with the flywheel. Now I see that the pinion gear in the starter motor is not a large enough diameter to fit with the teeth of the flywheel. HOW COULD THAT BE? There is no up or down adjustment on the starter motor mounting. The fly wheel is where it is going to be. Could the starter motor be the wrong one? The solenoid is at a right angle to the mounting bolt holes and that is the only way I could see to mount this starter motor. I had a starter motor that had the solenoid at 180 degree from the mounting bolts but that would not clear the tractor frame.. I have the ONAN P200G Service Manual but it does not cover this problem. It does not give the starter motor number either.

I have attached pictures of the gear engaged showing the gap between the gear and flywheel (first picture slightly dark).. Second picture is of the gear disengaged. Third picture is gear disengaged from different angle. Fourth picture is of the spacer bushings in mounted starter motor and engine block. The last picture is of the electric fuel pump for the same engine that is not working. Does anyone have a replacement for that fuel pump?

I have had good luck with Facet brand electric pumps -12v...1.5 to 2.5 psi  - available online at pegasus auto racing supplies.. need to keep the pressure low to prevent damage to your carb....:twocents-02cents:

The solenoid is at 3:00 but I don't have a number for it. The pinion gear is missing the flywheel. Any help or advice?

I don't have a number for the starter motor. I had my local Toro dealer find it for me. I still wonder if the is one of those cheap China motors. I just seems that the starter gear is already worn down or is not the right diameter to engage the flywheel. Do you have a used starter motor the would fit and still works?

Thank you

This is what  I bought - works really well --the cylindrical types were too expensive for me...might be better - I don't know..:twocents-02cents:

Nice price on the US made Facet , thanks for that - local JD dealer wanted $100 for the same pump , ouch . No real difference between the cylinder pumps vs the square block types - it's still just a solenoid plunger and a set of check valves unless it's a rotary which is a whole different ball game .

      My mule drive fell apart when I was plowing this winter and I grabbed all the parts I saw, but I'm not sure I got everything.  Seems like there should be some spacers or washers to separate the pulleys.  When it goes back together, I'll put a cotter pin through the nut.

      I got a new coil for my 1988 520-HC. I was having problems starting it when hot. I tested the old coil primary and got 3.3 ohms, the new coil was 3.4 ohms. The secondaries were open on the old coil and 21.66 k-ohms on the new coil. I got some metal bar stock with holes in it at Lowes to make brackets. I used a hose clamp to attach the brackets to the coil. I clamped the brackets to a large socket and cut a little at the bend so it would bend completely around the socket. Then I beat it around with a hammer to form the curve to go around the coil. The tractor started right up and ran great. I was about to mow with it and I noticed I had a flat in one of the front tires It would not pump up and it has a tube in it.I took the wheel off and the tire off the rim and found a big hole in the tube then I found a lot of wire coming out through the bead where it contacts the wheel I have four lawns to mow tomorrow and I desperately need a tire or tire and wheel. @ericj do you have anything I can use? I tried to pm you and it won't let me. It says " ericj cannot receive messages. " when I try to send it.
