416H

[ML3 2,363]

Picked this up yesterday. Was only an hour away. Seller said it was sitting for a few years so he had it serviced to get it running. Was asking $800. Got there & cranked w/no start. Ended up getting it for $300! Got it home & after using my small benchtop 20v blower to pressurize fuel tank it started right up! Everything appears to function. This will be new tractor to use with my Bervac. After the heat wave is over I'll go through it addressing maintenance & any possible needed repairs. Paint is faded so hopefully I can get it reconditioned.  

 

Have to get manuals printed off & definitely wanna address the "known issues" with this model. Onans are all new to me.

That red should come back with some elbow grease and determination.   Good Luck with it.

@ML3  perfect stage / condition  for this , done this on my  3 horses , and any  similar  faded / neglected  anything I pick up , base line  simplicity , penetrating  aerosol  spray down , all / every  area  , like to  leave it in hot sun  for hours , to heat up absorb . deeply into  paint base , nothing about this is  quick , days in  , try a spot  with a clean , mineral oil  , cloth  rub down , if it  breaks  thru , suden clean / clear  color depth  , you are on your way .  like a 6" electric palm buffer  , with a  cleaner wax  , don,t push it  , has to  be easily  shown , once mine have shown themselves ,  I  only  gently  rub it down  with a clean cloth  and mineral  oil , cloth  stays clean / clear , no dust or dirt , many years in on this , no rust or faded paint  , fearful  /  worried ?   try a  small area  , thats how I started  ,  give it a try , pete

Good engines when properly maintained just like many others.  

On a WH it's the 20 HP that has the more common issues due to lack of cleaning and overheating.  

The 16 HP is less prone. 

 

The New to the Herd list might help some.

Looks like a nice addition to your herd.  You'll have the paint shining in no time.

Nice find!

I”ve not seen a 416 with the 6” wheels and a 37” deck mounted before.

As noted above, Onans will serve you well if you take care of maintenance and cleaning.

The fuel does drain back if left for a couple of weeks, but the pump works fine once the engine is running. To that end, we added an outboard motor squeeze bulb to the fuel line. Give it two or three squeezes (it’ll get firm once the carb is fully fueled) and then the tractor starts right up.

The 20 HP has .030" more lift on the intake lobe and the carburetor has slightly different jetting.  The idea that the 20 has more problems, in my opinion, is just Wisdom of the Crowd.

I never have seen the smaller wheels on a 416 either but I'm by no means an expert. Might swap out wheels from the Workhorse.  

 

The deck when fully raised rubs at front of rear tires.

Me neither!

The tricks with the 37” deck are the angled, 2-blade setup (which needs the smaller front wheels for clearance on left turns!) and the capacity to run vac-lift blades that permit bagging without a bulky, separately powered chute. These are valuable features to some folks. 

If you choose to switch to the 8” wheels, you’ll want to switch the spindles, too, to keep things level. They are an inch shorter for the 8” wheels. Of course, then you'll have to switch to a 42, 48, or 60” deck! Some members want the taller 6” spindles with the 8” wheels when they go to larger (i.e. 24 or 25 inch) rear wheels.

Sounds like a good candidate for an electric fuel pump.

The 416H is my favorite tractor, but it does have some issues.   Here's what I do to mine:

1.  Install a foot pedal control.   I hate the hand controls,  especially on that model.  I built my own, but there are a couple you can buy.  Huge improvement. 

2.  Install a new fuel pump.  Since OEM Onan pumps are not available,  and I don't trust the Chinese knock offs, I  installed a Kawasaki pump as shown.

3.  If the 9 pin isn't burnt, clean it and put Noalox on the pins.  If it's burnt,  replace it with Packard connector.   You only need seven of the nine pins on the 416.  I used a 5 pin and 2 pin connector, but 8 pin connectors are available.  

4.  Run a wire from the battery positive on the starter to the voltage regulator/rectifier to take the load off the 9 pin.   Fuse it as shown in the pictures. I used the unused white wire for the cylinder head temp sensor.

5.  Clean the carb carfully.   Take out the main jet and clean everything thoroughly. 

6.  I have removed, split and  resealed the intake using Motoseal.  If it has enough hours on it to be due for a decarbon and valve adjustment then that would be an ideal time to reseal the manifold. 

 

Just some thoughts.  How many hours on it?
