Cummins ISC 8.3 Maintenance and Operation

I recently joined Cummins Power Club (10% off parts and labor) and have our first appointment scheduled for next week for valve adjustment.

On the Power Club website I noticed a "Recreational Vehicle Maintenance and Operation Quick Reference Guide for the ISC8.3 Electronic Diesel" which is the engine in our 2000 34'.  I've attached a copy to this posting.

Here are the questions that raised for me that I'd appreciate feedback on:

1.  What/Where is the Vibration Damper referred to in Component Maintenance?
2.  What/Where is the Coalescing Filter referred to in Component Maintenance?
3.  What/Where is the Particulate Filter referred to in Component Maintenance?
4.  Why is a DEF filter referred to unless I have the entire wrong engine reference sheet?

Any other comments for this diesel newbie?

Thanks

2.  What/Where is the Coalescing Filter referred to in Component Maintenance? AIR DRYER
3.  What/Where is the Particulate Filter referred to in Component Maintenance? YOU DON'T HAVE ONE-- ONLY ON NEWER EMISSION-CONTROLLED ENGINES
4.  Why is a DEF filter referred to unless I have the entire wrong engine reference sheet? SAME AS #3

Any other comments for this diesel newbie?

Randy, The Power Club will save you a bunch of dollars. On our brake work and fuel pump rebuild we saved over $300. Most Coach Care facilities will remind you to update your PC account when it's due and you are there to have service.

Photos below of the vibration damper on my C8.3 (mechanical) engine.  People also call this device a crankshaft damper or torsional damper.

One thing to watch on your vibration damper is that the 2 index marks stay lined up.  You can see them in the 2nd photo - two lines scribed on the metal, with the black rubber ring between them.  If the damper starts to come apart internally, the outer metal ring can slip out of place, which will cause the index marks to move apart.  If misalignment exceeds 1/16", you should replace (or rebuild) the damper.

Also check the condition of the rubber section between the inner hub and the outer steel ring.  The rubber should not be cracked or extruding more than 1/8" above the surface of the adjacent metal parts.  It definitely should not have any pieces/chunks missing.  If it shows any signs of distress, replace (or rebuild) the damper.

David, Service is next week. I'll report cost when I know it.  Service writer guessed no more than 3 hours plus parts if needed.

either that service writer knows a lot more than he should about foretravels or  he has no clue as to what to say when you are bringing in a diesel pusher.  Luckily he shouldn't be too far off on that estimate since the bed actually flips up easily but on some sob units you could spend three hours just getting to the top of the engine through the bed.

I recommend being a nice guy and dragging the mattress to the front for the tech, less chance of beheading him if the gas struts decide to go weak.

After my first experience getting beaned by our bed platform, I fabricated a high-tech bed support device: a cut-off broom handle.  I keep it in the corner of the aft closet, secured with a strip of Velcro.  Simple, effective, and OSHA approved!  ^.^d

Mine came with the fail safe bed support, and being an ored it also came with a battery box/step cover aux. support strut:)

Now just have to build a creeper to span the bed supports so I can lay on it to work on my V-8 topside.
