  1. B43E Help Wanted

    6bg6ba The way I read Boomer's response he was telling you that without machining the flywheel on the back side it would crush the ignition rotor not the ignition module. It would definitely be worth checking that out as you would only find that to be true after putting the flywheel back on, drawing it down tight and ruining the rotor. Gary
  2. 520-HC flywheel shroud removal

    Guys, Best way to hold the flywheel during removal is the use a pair of vicegrips on the ring gear up next to the governor arm support casting............Works every time! ........Gary
  3. 1991 520h P220G spark but rough running?

    Mastiffman, Use the following: Onan Coil Test Procedure IGNITION COIL To test primary and secondary windings within the ignition coil first make sure the ignition power is off and coil is at room temperature of 70°F (21 "C). 1. Use a Simpson 260 VOM or equivalent. 2. Place a black lead on negative (-) coil terminal and red lead to positive (+) coil terminal. Primary resistance should read between 2.90-3.60 ohms. 3. Change resistance setting on ohmmeter. Place ohmmeter leads inside of spark plug cable holes (Figure 3). Secondary resistance should read between 14,500 - 19,800 ohms. 4. If either of the above resistances are not within specifications, replace the coil. Hope this helps............................Gary
  4. Onan P220 vavle spring tool?

    Razkid, I use one (like you have pictured) on my Onans everytime I tear one down and it works just fine. They are a little tricky to get the end adjustments right for the spring diameter and the Roto-cap diameter but after using them a couple of times you get used to doing it.........Good luck with yours..........................Gary
  5. Onan oil leak

    Josh, Might be just leaking around the bolts...........They are threaded through into the crankcase. If that is the case you could drain your oil and take them out one at a time, clean them and the holes with a suitable solvent, apply Locktite thread sealant and re-install them tightening them to spec. However, the gasket behind the bearing plate might be leaking in which case you might have to replace it. I would do the bolt thing first. What do you have to lose? Now, having stated all this, there is a seal around the crankshaft that is pressed into that bearing plate. If that is the case the clutch will have to be removed to access that seal but it can be replaced without pulling the engine...................Gary
  6. Wheel horse 520 on internet

    There are two of them listed by the same guy. A 520H and a 520-8. They are are not for sale for $750, the starting bid on each is $750. Whenever someone breaks the ice with a bid I doubt they will stay at the $750 mark..............but I've been wrong before! .........................Gary
  7. Flywheel Mark Onan 29/29E D-160

    Leelee, Again my apologies! I did not notice the tractor model number within your thread title. Boomer is correct as to the timing mark beingon one of the fins. I should have looked closer before I took the leap! ................................Gary
  8. Flywheel Mark Onan 29/29E D-160

    Leelee, I thought I had more than one flywheel "out of storage" so I could compare to see if the timing marks where any different between units but that was not the case. I only had one I was able to access without opening several storage containers. Anyway I took a couple of pic's of a P Series flywheel for you to view. The first photo is of the complete flywheel viewed from the "cooling fin" side. The second is more directed at the timing marks. I added some red arrows pointing to the timing mark and to the letters. You can clearly see the timing mark that is cast into the flyweel running from near center of the flywheel to the outer surface where the ring gear is mounted. There also are two letters in raised casting shown, a "T" and a "C" for "top-center. So I was wrong in stating to you that it was on one of the cooling fins and I apologize...............I hope this is clear to you but if you have any questions certainly feel free to ask.........................Gary
  9. Flywheel Mark Onan 29/29E D-160

    Leelee, It was such a gorgeous day here for an Indiana January day my wife and I took a drive over to Lake Michigan and spent the day so I did not get the photo's for you. I apologize for that, as I know you are anxious for them. I will try and get them for you after church tomorrow though it will be later in the evening before I can get them posted for your use..................Again I apologize......................Gary
  10. Flywheel Mark Onan 29/29E D-160

    Leelee, I have a couple of flywheels down in my barn that are removed from crankshafts. I will try and get down there tomorrow and see if I can get you a clear picture of the timing mark...........If not tomorrow it will be Saturday, but I will get it for you.................Gary
  11. Flywheel Mark Onan 29/29E D-160

    Guy's, The mark is actually on top of one of the cooling fins of the flywheel. It is very difficult to see but once found you can easily distinguish the difference from the rest of the fins. I find it helpful to paint it with a paint stick once it is found to aid in future use.......................Hope this helps...............Gary
  12. @ACman Thanks! I appreciate your response..............................Gary
  13. @ACman Did you put 7.5's on front or end up using 6.5's? .............................Gary
  14. Thanks Denny/WVHillbilly520H! I appreciate the response and the info included...............I will contact them......................Gary
  15. Denny, If you don't mind me asking, where did you get the replacement "footrest pads" that you just installed? I have a unit that needs them replaced too! Thanks in advance...........Gary
