Thanks again for the help Lots of Onan info here: www.These garden tractors all have something in common, they are powered with Onan engines.

A: It sounds to me like you have water or dirt in the carburetor. Take the top off and check for dirt or water.

Take out the front jet toward the muffler, blow air through that orifice. Put it back together and adjust that air screw by the muffler and I would like to think everything now would be O.

Q: I have a Simplicity garden tractor with a tired Onan engine. Are parts still available for Onan? A: Onan is slowly going out of business as they did not build an engine to pass our pollution standards.

Our 23 horsepower Vanguard engine is by far the best way to go and is the best air cooled engine that money can buy. When I remove the air cleaner I can see the fuel being squirted into the carburetor when a surge comes. I have rebuilt most of the motor and installed a new carburetor and it is still doing it. Do you have any advice? Do you have a repower in a Vanguard? A: It sounds to me like you have a leaking intake manifold. The way they have built the intake manifold is a bad design.

Yes we have a Vanguard V-Twin overhead valve engine and made to order installation kit for your application.

It Runs great. I replaced the rings about 2 years ago and so the engine is clean inside. When I start it, it often kicks back. Sometimes it locks up the starter. When it does this I have to take off the side cover and pry on the cooling fins to turn over the engine a small amount to get the starter to work again. I replaced the spark plugs and this seemed to help some but now it is kicking back and locking up the starter again. It even unscrewed the nut on the starter twice and I had to take the engine out to put the nut back on.

A: When you had the engine out did you check the 2 holes in the block where the 2 starter bolts go through?Skip to main content Onan Generator Parts. Only 3 left in stock - order soon.

After repairing and assembling the unit I thought it might be interesting to show what sliprings and brushblocks look like and where they are in this unit.

The little KY hides it brushes behind a flywheel on the end of the rotor so it is a little harder than most generators to service the brushes.

Due to the unit's weight and varied tools needed most people will find its easier and less frustrating to have this work done at a service center. Besides that you have to remove the unit from its mounting location.

Not to mention it weighs over pounds. But i will go through the slipring clean process and brush change. The first picture shows the generator with the cover off so you see, from left, engine, generator main body, plastic wind tunneling. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This is what the rotor looks like in this unit. It is a hollow shaft with tapered end where the flywheel goes.

Then the outer bearing then the brush slip rings. Then the nylon shell where the windings are found. The far right end is an internal taper that seats on the tapered crankshaft end. The pencil point is pointing to one of the two sliprings.

These rings are hooked to the windings in the rotor and electricity travels through them from the brushes that ride on them. These rings are dirty and need to be cleaned. The cleaning is easy. Just use a piece of scotchbrite and clean them until they are very shiny. In a later image you will see them clean. To check the rotor just put an ohm meter lead across both rings and see if the reading you have is what the service manual calls for.

Usually if a rotor is bad it is because the windings are burned or broken. Then the entire rotor, as a unit, is replaced. This housing is what bolts over the generator main bell housing. The large hole in the center is where the bearing on the rotor sits. The two bolts the pencil points to is where the Brush block is bolted. The brush block is just a plastic or ceramic housing that holds 2 carbon brushes with wires coming out of them.

The brushes are rectangular and made of a carbon material.By Duramax7man7 MastiffmanJuly 31, in Engines. So if you've problem solved all other aspects regarding your non-starting Onan engine with electronic spark control and come to the conclusion that you need to replace the Ignition module, keep reading. This is a decent step by step and doesn't require the engine to be removed the from the tractor. Although it might be a little easier to work on while on a workbench.

The part numbers for the Module and ring if needed are below: Ignition Module: Spark Ring: Here is a list of the tools that I needed to complete the job from beginning to the end. They are named from left to right in the photo with the tools at the top of the photo last from top to bottom.

Flash light optional but very helpful at times Pry bar used to lock flywheel from turning. Old Tooth Brush for cleaning of dirt if needed PROCESS: - Obviously the first thing to do for safety sake is to shut of the fuel at the tank and remove the battery cables - Next, remove the two screws that hold the fuel pump onto the shroud, move the pump off to the side and replace the screws into their holes for safe keeping. NOTE: Close the Choke all of the way and stuff a clean paper towel into the top of the carb to prevent debris contamination.

Work slow so you don't bend or brake anything and it will come off pretty easily. So I took mine outside and pressure washed it to give it time to dry completely before reinstall. This needs to stay mostly in as a pressure point for the puller. Don't forget about the flywheel bolt first!

My flywheel was pretty dirty on the inside and between the magnets so I felt it necessary to use the toothbrush and air gun to clean it out.

Underneath, you'll see the ignition module on the bottom side of crank. Remove those and open the wire retaining clip on the side of the gear cover and the module comes right off.

That needs to be there. This debris builds up enough to cause insulation around the module. The module being an IC Integrated Circuit is designed to handle only so much heat. Over time the extra heat and expansion with contraction when cooled back down causes a when point in the modules chip circuitry and eventually breaks.

Thus causing the engine to shut off during operation for the first time. Once the engine cools, the chip materials contract, allowing the circuit to bridge again only until the engine heats up enough to break that signal and then becomes a cycle until replaced.

While everything is out, if needed or your OCD kicks inclean the cylinder heat syncs and general area before re-installation of the Module, Stator, Flywheel and Shroud. Mine wasn't to bad so I quickly used the toothbrush and air gun to break free any layered gunk and blew it off with air. At this point, go ahead and reinstall the Shroud making sure that the fuel pumps vacuum line is accessible through the front hole in the shroud, along with the shroud bolts, coil, coil wires spark, condenser, module and switch and tighten rear shroud bolt.Sure, ad-blocking software does a great job at blocking ads, but it also blocks useful features of our website like our supporting vendors.

I need a new flywheel for my Onan. I don't have one that can be refurbished. Has anyone matched anything from a tractor or other application that would work with this setup? I've tried to find specs on flywheels for various engines and tractors but specs are all but nonexistent. Any help or recommendations are welcome. Is this an MEPa, or some other Onan application? I have wondered if the was a civilian equivalent to the The s have a LPW2 motor.

A lot have been surplussed lately, someone must be parting one out. According to the Parts TM available on this site the part number for the flywheel probably the same as a with the LPW4.
