[SEL] IHC M 3 HP Status

Tue Mar 7 15:10:45 PST 2006

Hi List,
I picked up a non-running rusty IHC M 3HP igniter type about 6  weeks ago.  
Needless to say, it came with a stuck piston and many missing  parts (igniter, 
magneto, fuel tank, and fuel lines).  
Finally after removing the head, governor assembly, carburetor,  
disconnecting the connecting rod, etc., I managed to get the piston out.  I  made a plate 
to replace the head to fit the end of the cylinder.  I  drilled and tapped a 
couple of holes into this plate to allow filling of  the cylinder with old oil 
and to permit pressurizing the cylinder with a grease  gun.  This pressurizing 
plate was also machined to allow the installation  of 4½" "O" ring to seal 
the cylinder.  Before installing this plate, I  honed the cylinder.   This oil 
mixture was allowed to sit in the  cylinder for a few days.
Yesterday, I began to pressurize the cylinder using a grease  gun.  I did not 
feel any pumping pressure when using the grease gun.   However, I did sense 
piston movement.  The piston was originally stuck  in nearly the BDC position.  
After moving the piston about ¾", I stopped,  drained some of the oil out the 
cylinder and with much effort I was able to push  the piston to its original 
piston.  I left the cylinder filled with oil and  applied about 90 psi air 
pressure.  I let this sit over night.  
This morning, I drained some of the oil out the cylinder.  I  placed a piece 
of a 5' -  4" x 4" beam on the flywheel rim and held it  with a chain.  Then, 
using this beam as a lever, I was able to turn the  crankshaft which moved the 
piston until the crankshaft journal no  longer made contact with the rod.  
The pressuring plate was removed and the  remaining oil and grease were drained. 
 Then, I was able to place short  piece of 2" x 4", through the crankcase on 
the end of the connecting rod.   Using a heavy hammer, I pounded the other end 
of this 2" x 4" until  the piston came out.
Now, I have to get rings freed and clean up the  piston.
Several people on the SmokStak Chat Room advised me on how to  proceed with 
the above effort.  Without their input and encouragement, this  piston removal 
exercise wouldn't have happen so fast and with no breakage.
