WH 520-H 2 Stage SnowBlower Maintenance Questions

Recommended Posts

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

I would try and find a new cutting/scraper edge unless you weld the new piece to the bottom there may be interference with the auger, as far as pulley and jack shaft, I would tear the gear box down and have a machine shop either make a new one or weld it up machine it to size and re-key it I would NOT weld the pulley to the shaft unless it was just long enough to finish out removal of blizzard, Jeff.

are there any rebuild kit available for these gear boxes?

I know a guy that can mill a new saft but he would probably charge about $100 and a new pulley is $54 from Toro.

Did I mention that I am cheap?

I'm cheap too but (fortunately) I'm a machinist and could do it myself, but as far as a rebuild kit for the gearbox I really have no idea, but on the flip side if there is not a lot of wear on that shaft a keyway could be cut 90°-180° from the original and with a new pulley with a set screw should fix that problem, Jeff.

After removing the bearing, that keyway could be welded around a brass key like @Ed Kennell and others have done to axle shafts...

Here is the post of the repair I made to an axle keyway.   However you decide to make the repair, I would also add a second set screw 90 degrees from the keyway.

Common size dive pulleys are available at TSC for about $20.

      Hi Guys,
       
      Does anyone know where you can get the correct size, 90 deg crimp fittings for the hydraulic line going from under the hydro trans to the lift valve on the 520-H? I found a Gates fitting with the correct thread size but it was too long on the thread end. It came down too far under the transmission to allow the hose to come over the frame.
      Hopefully I described this well enough?
       
      Many thanks,
       
      John

      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???.

      48" side discharge mower deck, used only 1 summer. This deck is in fantastic shape. Little bit of rust, very straight and spins like new. I can ship Fastenal at cost, or pick up. 300.00 OBO. https://flic.kr/p/X6JGCv

      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?
