Starter Pinion gear not contacting flywheel correctly

Recommended Posts

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 .

      Hey Guys,
       
      Doing some Maintenance on my 2 Stage snowblower ID # 0644SC01    60442  Ser# 9317
      Problem # 1
      Last winter Noticed that the Drive Pully on the Blower was wabbling
      This spring when I took the belt off I noticed that the Keyway on the spindle and pulley was worn.
      The Key ways actually rounded
      The set screw in the pully to spindle was missing.
      So, what is the easy/cheap fix that will solve this issue
      Thinking of mig welding the pulley to the spindle.
      How Stupid is that idea?
       
      Problem #2
      The scraper Blade is well worn. Should I try to find a new piece or weld something to it?
      What would you guys do?
       
      Thanks In Advance for taking the time to Respond,
      Best Regards,
       
      Kevin B

      Boy oh boy I love my 520H but I can not seem to find/read some of the numbers on it to look up my tractors info. It has a 20hp Onan that will need work soon. The tractor it self needs work. I am going to fully restore it but can't  look for parts cuz I have no info on it. ANY help would be greatly appreciated.  Under the seat I find I.D # 3120OE01, then 15426 and what I can read of 9264???.

      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.
