MERC OM 906LA

Right after we got the
 valve cover off. 

Wrestling fuel lines.  Each injector
had it's own separate high
pressure pump.

Block with head, oil pan, oil pump,
turbo, and exhaust manifold
removed.

The last couple of weeks have been really exciting for me.  I dove headfirst into engines with a couple of the other guys.  Interestingly enough, we chose the MBE 900 out of the storage garage.  I tried my best to follow the service manual as we dis-assembled the engine.  I made a point of looking at each component and piece we took out to look for wear or even figure out how something worked, so it took us a couple of days for tear down.

Once we got it taken apart, parts organized, and cleaned parts and surfaces I started taking a bunch of different measurements.  Those included a ton of stuff that I've always wanted to know how to do properly.  I learned to use the dial-bore gauge efficiently, as well as a lot of measurements using the micrometers.  Some of the measuring tools we used required a bit of figuring out how to use them as we went; so it was both fun and challenging to figure out different ways to skin a cat.

Quite the difference in
 torque to yield bolts.
Before and after.

Top of head.  Note the 3 valves.
2 intake and 1 exhaust. 

Looking at the bottom side of the engine
at the crankshaft.  Very cool,

GOTTA keep those bolts and parts
clean and organized!

A bit of fun on the side:  changed out my wheel bearings on my Ranger last week as well.  It was a good thing to revisit what I had learned from spring quarter.
