Backhoe....

[ebinmaine 67,255]

Today I put a fresh air filter on and reinstalled the freshly charged battery. 

Then, put the machine to work.  

We built this short closest  section of stone wall by taking the rocks from the other side of the driveway and carefully placing them so gravity is the place holder.  

 

 

After that was done I took the cylinder head off to prep for removing carbon. I've seen worse. 

 

 

 

 

The piston does rock a little but it'll be fine for awhile. 

 

Next chance I get I'll remove the carb and check the valve lash adjustment.   

 

[ebinmaine 67,255]

Got the carb off and popped the bowl off. Some standard issue muck in there so I squirted that out with brake clean. 

Pulled the valve cover down too. 

Next time ... Valve clearance check.  

 

 

[ebinmaine 67,255]

Last couple days I've been getting a little time on the M16 again. 

The carb from isavetractors was showing some wear at the top throttle shaft bore. Odd considering it has very few hours on it. 

I had a spare here with a good solid body so that's being cleaned up in the ultrasonic. 

 

I checked the valve clearance. 

Intake. .011

Exhaust. .018

 

Adjusted the intake down to  .008

 

Made up a set of gaskets from an old transmission case half gasket. 

 

Headed back together soon.

Installed the valve cover with my super amazing hand crafted gaskets. 

 

Finished up hand milling/planing the cylinder head. 

 

Wire brushed all the head bolts. They appear in good shape so they're reused this time. 

Dipped all head bolts in oil then installed.  

Torqued to 30 lbs ft all around the circle, twice. 

 

Installed the top cover after cleaning it up, as well.

I've been told in the past that the actual sequence any particular cylinder head is torqued can be varied some. ... 

As long as there's a good attempt at keeping a back and forth sequence as in the pic above.

They all seem to go across the short dimension first, as well.

You should have asked your Grandmother how to roll out dough, you know, from the center out.  It ain't any more technical than that.

That is what I go buy Eric. Kohler manual. I do not mix bolts either. 

[Retired Wrencher 5,441]

Good job keeping that 16hp in good working order Eric. What do you use to cut the gas kits? And is that gasket material.

It's a leftover piece from when the factory made a transmission case half gasket.

Good sharp kitchen shears and a leather hole punch for that small center hole.

Double check the Kohler manual about oiling the head bolts before assembly.  

 

The resulting bolt tension for a given tightening torque is higher when the bolts are lubricated than when dry.

 

In this application 25 to 30 ft-lb of torque on that size bolt is not much, and lubed threads probably won't make a difference. 

 

In some applications where the bolt torque is near the maximum for the bolt, adding oil to the threads could result in a stretched bolt.  A stretched bolt will produce a lower clamping force,  which could cause the bolted joint to fail.

Good advice there. I'll take a look.

  I didn’t know you played the trumpet  ! 
    Not sure how or where I got this gasket hole punch kit but I’ve had it for years. 
 

 

 

 

 

[ebinmaine 67,255]

@8ntruck

I went back and looked at the Magnum manual. 

I'm sure I'm missing something but I couldn't find the bolt torque reference for dry vs oiled.  

 

I know the older K Series manual does recommend oiling the head bolt threads. 

 

 

 

@Sparky those are cool 😎

That's a great set of punches. Garlock is still in business but I think those sets are NLA by a few decades

I lube threads to torque but probably give more credence to being clean. Corroded, dirty tapped holes around the exhaust port (IMO) will not torque like the others.

[sjoemie himself 3,068]

Great advice from @8ntruck especially because this is the head of an engine. Besides the valid point he makes about stretching the bolts I can imagine that the applied oil will burn off when the engine gets hot which may effect the applied torque aswell.

 

I have'nt had a look in the WH manual but in the Claas manuals I work with there are either torque settings specified specifically for a part or you are directed to a section with general torque specs. Those manuals state that every torque setting applies to dry threads stating that applying lubricant can lead to loosening of the bolt connection.

 

Last but not least, there are pretty good charts online which let you see the difference between lubed and non lubed threads and some even give you the difference between old (rusty and/or oily) threads versus new (clean and/or dry) threads.

I finished up cleaning and rebuilding the carburetor this evening.  

Took a fair amount of extra time on this one because it was painted black and covered with dirt so it had a bunch alternating dips and sprays in the ultrasonic cleaner and brake clean.  

 

Here's the before n after.

Better hope the dirt and paint weren’t essential to its operation! 

[ebinmaine 67,255]

Got the carb set in place... 3 times. 

  

 

Between needing to set the linkage in place for the choke,

Then needing to swap choke shafts from the old to new carb, I got plenty of practice in carb installation.  

 

Then when I went to mount the air cleaner the holes didn't line up. 

Well ok fine then. 

I tapped the holes pictured below in red.  

 

 

Got everything else all in place and started up. 

Runs good. Drives good. 

 

So I used it to move some stone on the erosion control project.

Mike that looks like a great set of pinches. Very well made.What is you largest size?

Looking good Eric. Get that big block 16 back to work.  I like it!
