GMC, Full Mechanicals (continued)

Continuing on the “Full Mechanicals” project,  now that the motor is out we want to break the motor down before taking it to our machinist.  full-mechanicals-project-25  Heads now together over on the bench, doing a forensic on the lower end may show us some stuff.  full-mechanicals-project-24  Pulling piston #1 rod cap tells us something important.  The scrubbed cap surface is not the bearing.. it’s still on the crank! The bearing has been turning in the journal full-mechanicals-project-20

Could be the motor got hot once, the journal opened up allowing the bearing to spin around.  No metal or bad scores on the crank, there is some ridge on the cylinder bores so it may have to go to 30 over.  That’s fine….  This is a 403 motor…. how do we know that?  Well, look on the side of the block  full-mechanicals-project-28  So today, in pieces, the motor will go to the machinist.  We pulled the motor apart to save time.  Good machinists are always busy… he’s telling me 60 day, OK… “DO YOUR BEST” as the Cub Scout motto says…

Back to the pull down on the coach, Anthony carries fuel tanks like he plays his accordion.  full-mechanicals-project-23 No?  Well you may wanna look into it… you’ve got the look brother….Tanks have a bit of surface rust full-mechanicals-project-22  Taking them to our radiator shop having them pressure tested there were no leaks full-mechanicals-project-21  We’ll have them cleaned out then the exterior gets a full coat of POR-15.  The original holding tank will come out today… Oh boy!  full-mechanicals-project-8  Stay tuned for that.

OK, lemme get today started… getting this plunking done here early before breakfast I’ll be able to hit the ground running after that.  Will be another great day.  I hope to have Bill’s awesome 23′ rear bath on the ground the end of the day.  Wish us luck…  see ya tomorrow…bill-finals-20.
