Let's Play Name That Part

1: Radiator support. Mostly a collision safety thing.
2: Red is a CAC intake tube (boost air) to the CAC from the turbo, Teal is the intake tubing from the air cleaner. Yellow, there, I think is the ECU -- I'm not 100% ON THAT engine. Green is some wiring harnesses, probably engine, all neat and tidy.
3: Red is a pitman arm, yellow is the drag link.
4: I can't tell if you were circling the slack adjuster or the brake camshaft. The bit attached to the chamber is the slack, which is splined to the camshaft.
5: Blue is more intake tubing, boost air, goes off to the CAC. Red to the left, is the exhaust downpipe, yellow circled the v-clamp for it. You have the exhaust (turbine) and intake (compressor) sides of the turbo circled. I think purple there would be the VGT controls and the oil feed for the turbo, sorry, don't work on Cummins enough.
6: Red is either the pushrod for the brake can or the slack adjuster. Teal is the axle, yellow a shock, green the u-bolts and spring top saddle, and blue the spring itself. Leaf springs, of course.
7: A/C compressor. The two wire connector on the harness fed to the front of it is for the A/C clutch.
8: Yellow is the height control arm, mounted on the height control valve for the air ride. Red is the height control rod.
9: Pivot spring. Holds the shoes against the anchor pin. The opposite side has a return spring that holds the shoes together against the s-cam.
10: Yellow is the brake spider, housing the brake camshaft -- your brake cam bushing is in there, hence the grease fitting. Red is the torque arm. Green looks like the leaf spring there.
11: Red is the pin that keeps the saddle pin for the fifth wheel from coming out. Yellow is actually the adjuster -- I assume it's a No-Slack fifth wheel by the looks of it.

Any more q's, feel free to ask. I'm a mechanic, just hang out to read here mostly. Glad to contribute.

 

thanks i enjoyed that thanks

 

Do not see water pump, air compressor, or torsion bar from the pics...but I'm not familiar with cummins at all.

Hub Seal will be a hard one to get a good pic. It will be inside the hub. In my opinion a trailer is the best way to get a pic of a wheel seal.

Pic 3 the steering box is what the pitman arm is attached to.

Pics 5 and 6 you can see an "S" pipe...the beginning on the back of the turbine housing and the other end popping out from the bottom of the frame in pic 6.

Neat thread though. Most do not pre and post trip as they sould. I just turn wrenches I don't drive. My hats off to you for what you are doing! You will also gain a great deal of knowledge for repairs by doing what your doing!

 

did you go to a truck driving school? They should have showed you all of these things.

pic 2, yellow is crankcase filter housing, make sure they are changing this filter on a regular basis, I think the interval is 50-60k miles

pic 5, purple is vgt controller and coolant feed for turbo and vgt.

pic 3 is the gearbox for steering, the pitman arm is splined onto the output shaft of the gear box

your waterpump will be directly below the a/c compressor mounted to the front of the engine on that cummins

 

It's good you asked but you've been driving for a year!!
