I am getting some parts together in hopes of putting my Wisconsin ABN back together for my Waterloo 40.  I discovered the PO neglected to include the head bolts & the base bolts in the box of misc parts.

 

The parts list shows some of them as "special hardness".  Any idea what that means?  Is it an "all bolts are grade 5 unless otherwise specified as grade 8" type situation or are they truly special?  

 

Also, the parts diagram for the oil pump shows the top check ball above the pin (red arrow).  Mine is below the pin, above the spring (green arrow).  Which is correct?

Wonder about special lengths too then??  Might try the guys on the PowerKing economy forums. They used WI on early models. Bolens guys too, they used them longer.  I know nothing on them, so can't help. Modern engines have one time use bolts that 'give" a little and twist to make torque and can't be re-used. Would not think that was an issue back in old days tho. Swap meets this summer!  Bet you want them NOW tho, huh?

Super! I can get those tomorrow.  That just leaves the question about the oil pump check ball.  Anyone?

That is odd ?

I think the check ball housing was put in upside down on yours unless it is different, may explain the rod and cap going, what is your serial number for the engine ? is there a variation letter or number after the model number ? this need to be checked out.

Just pulled out my manuals to conferm, ABN is as you posted with the ball on top held in by the pin, AKN is the same, the newer AGN uses a cup type instead of the pin and is also on top.

Just in case the pump has been switch out or modified please post a picture of the assembly.

You ask & I flash.  I think you may be right on the up-side-down theory.  You can see the pin is worn flat.  That would explain why the crank ran dry and the rod wore out.

 

How I found it:

How I think it goes back together:

Anyone say "Nay, go with how it was"?

Oh, and the data plate so you can look for extra secret coding:

You got it, thanks for the fast flicks.

Go with the manual and me, the pin is round, flat spot tells me a bad story.

 Don't forget to check it, fill the sump with oil and using the rod pump it until the trough fills with oil.

Flip it, run with it, keep the cap lubed.

 

Everything looks like a normal ABN with the serial, your good to go.

Well, I tried it both ways.  With the check ball above the pin, it hydro-locks.  If I install it with the check ball down, it works fine.  It works, but that doesn't explain why the picture shows the ball above the pin.  I did notice that the diagram shows the pin near the top of the plunger.  When you turn the plunger so that the pin is near the top, the ball is down.

Oh my god !!

You just found a 50 year old exploded view diagram error from the factory manuals for the ABN, AKN and several other they reused the same picture in.

I am going to have to pull the sump pan on my AKN and switch the plunger before i cook the cap and rod.

 

Look at Figure 4 in this manual, it clearly shows the pin above the check ball.

Always something new to learn.

 

Edit : my AKN is fine, looking at my photos and the bells started going off, just like you i remember doing the same thing and wondering, it is not a typo error, they just did not show the ball into the plunger first before the inserting the pin.

When you say it that way, it all makes sense:  The ball goes in from that end.  Duh!

Kind of a stuipid moment for me, felt like a moron for the rest of the day.

Very glad you uploaded the video, you saved our butts, once i saw that plunger, i knew something was not right again.

Now i can say with 100 % confidence you are all set.
