[SEL] IHC LB Engine Operating Observances

[FRM8198 at aol.com]

Hi,
In getting one of the new IHC LB acquisitions running, I observed several 
unique things about the oiling system on this engine.
    The oil gets to the rear oiling trough through a pipe which has wick 
extended         into the crankcase.  The splashing of the crankcase oil is picked 
up via this             crankcase wick and slowly lets the collected oil drip 
into the rocker arms and         valve stems collection tray located above 
the valve train.  
    The oil collection tray also has a collection felt to absorb the oil 
being supplied     by the collection tube via a metering adjustment.  There are 
two oil distribution     tube extending from this collection tray into the base 
of the valves.  Located             around each of the valve stems is a felt 
retainer assembly.  The oil which                 is absorbed by these valve 
felts is used to lubricate the valve stems.
    There is another hole in the collection tray which matches up to a hole   
                  located on the rocker arm shaft.  Inside of this rocker arm 
shaft is another felt to     hold oil that drips down from the collection 
tray hole.  There are two                         additional oil holes in the 
rocker arm shaft that are aligned with the rocker             arms to lubricate 
the rocker arms.
There doesn't seem to be a method of lubricating the push rod ends other than 
manually.
In trying to unstick the governor throttle plate assembly in the head, the 
throttle valve shaft was broken.  A replacement was fabricated from three pieces 
of brass material (7/32" tube, 3/16 solid rod, and ¼" square tube obtained 
from a hobby store) and silver soldered together.  
Any other IHC LB engine restoration or operating tips that others may have 
are appreciated.
