[SEL] Fairbank Morse Z Style D (ShoeBox/SaltBlock) Status Update

[Richard Strobel]

  Francis;
 Yes there are timing marks/methods.  I believe it has something to do with 
the split in the case but let's not take that to the bank yet.  Somewhere 
there is posted a manual for the "Z" but haven't found it yet.  I thought it 
was on Harry's but have failed to find it.  Will try gaggle.

> Hi List,
> Finally, the Fairbanks Morse Z Style D (ShoeBox/SaltBlock) has been
> completely disassembled.  All the springs (governor, compensating, and 
> throttle
> control) except for the valve springs and the speed control spring were 
> unusable.
> The governor spring came out in many pieces.  New ones have  been ordered.
> Some previous owner had installed the valve adjust shims in the  wrong 
> order.
>  The valve stems actually worn through the thin shims.   The thick shim is
> the one that should make contact with the valve  stem.
> The air fuel mixer valve butterfly was frozen and would not  move.  After 
> a
> little careful application of the "flame wrench",  penetrating oil, and a
> soaking in carburetor cleaner, the butterfly valve seems  to operate 
> correctly.
> The governor control rod and throttle  activating assembly were also 
> frozen.
> Again the heat wrench came to  my aid.  All parts are free.  The bolt that

> the throttle  activating assembly to the governor control rod snap during
> removal.   Luckly, heating the unit with the flame wrench and application

> The bearing surfaces on the camshaft have been polish.  There  are rust

> Since the timing gear on the crankshaft was damaged, inquiries were  made

> Association, Inc.) had a complete crankshaft assembly which he let me have 
> for  this

> main bearing has to be replaced.  A replacement bearing has been  ordered.
