[SEL] Baker Monitor

[Jim and Diane]

Hi Curt,

The pictures were great.  Now a few odds and ends from my Monitor 
experience.  The shaft seals and individual bearings on the cam shaft work 
fine.  The new bearings are 660 bronze from MacMaster-Carr.  The shaft is 
set up pretty tight but runs fine with no heating, the seals also seem to be 
doing exactly what they are supposed to do.  The gear wear that you show in 
the picture is exactly the same thing that I saw.  The 20 tooth gear was 
worn the same as yours.  This gear is probably too small for the job, if the 
Monitor were ever to be redesigned this gear should probably be a lot wider 
although it took a long time to get it this way.  The mating gear looked 
fine although I did not attempt to measure tooth thickness just eyeballed 
it.  I drilled and tapped both ends of the new camshaft for a 1/4 20 screw 
and used that to hold on two custom made washers to keep the gears on.  The 
original setup had both gears pressed on.  this might have been OK at the 
factory but I thought this was a much easier way to do it.  I don't have a 
press big enough to get the block into to press this together and did not 
think it was worth the trouble to try fab up something like a big C clamp 
for a one shot deal that I will probably never need again.

The first run of this engine was two days at Tulare and then one day at the 
March Field truck show.  Ran fine except that oil came out of the mains at a 
pretty good rate and really made a mess.  I was gradually cutting back on 
the oil, trying to make sure there was enough for the splash system and yet 
not to much to slop out.  I was going along pretty cautious here until I met 
a fellow club member who has an identical engine.  He has been running his 
with about an inch of oil in the crankcase.  I drained quite a bit out and 
this seems to have made a great improvement in the mess factor.
