WQ2014

I'm not sure I'm too keen on pulling doubles into the shop... I can put a 53' anywhere I want it but these are just ridiculous.

Well I guess I won't be doing it that way next time. According to Eaton and everyone I've asked that was the right way to take the input shaft out but I dunno about this.

Did some A/C work for the first time. That was a steep learning curve... Hey, go change the leaking a/c compressor! Okay then.

Changed a trans filter on an Allison and couldn't get it to communicate with the laptop to reset the indicator. The foreman, our engine tech, and an hour later we switched USB plugs on the computer and it worked fine.

And then there's this stupid stuff. Had to pick up a set of chains for my truck to make it to the main roads. 2wd and snow drifts don't really mix well.

WQ2014

No pictures this week but I've now experienced the joy of stuck s-cams... Two guys, an oxy torch, air hammer, multiple beating devices, and 8 hours later we had all 4 corners torn down and the hubs ready to go back on (New inboard drums... Yup, press in studs). Oh' it was a low deck with 12" brakes too so lots of room to work...

Been doing suspension bushings lately. The threaded steel on steel bushings are interesting... Weld them in and they have a nice "clunk clunk" brand new. I wonder if they make any noise going down the road?

WQ2014

Lift gate wouldn't descend fast enough for the guy... Of course the oem is long gone so I had to call the people that bought them out and get a troubleshooting guide emailed to me (It's not available to the public on the internet). Go figure.

After dropping the tank out to check out the screen and make sure it wasn't something stupid like cold hydraulic fluid I got out my 50ft lead set and went to town with my meter. The + battery cable to the motor had a 3.7v drop and the - cable from the frame to the motor had a 1.8v drop... Also found a 100 amp breaker in place of a 150 that trips constantly. That's no good however the motor isn't run during the drop cycle and it lifts fine so after hooking up the jump pack to eliminate the voltage drop from my troubleshooting I carried on.

Slide the gate all the way back and presto! Absolutely everything quit working... I can already tell this is going to be a nightmare. After resetting the circuit board I was able to get back to the original problem.

After working through the troubleshooting guide I determined it was an absolutely worthless pos written by engineers. Tossed it and continued... Release solenoids on the lift cylinders function flawlessly. According to the schematic they are returned directly to the tank. I determined that was b.s. after hearing a valve clicking at the pump. When the valve clicked with the switch the gate dropped like a rock. When it didn't (This is intermittent) the gate took easily 2 minutes to drop completely. The valve redirects the flow into the tank instead of though the pump. When it doesn't work all the oil tries to flow backwards through the pump into the tank and takes as long as a snail high on weed.

Either the valve is sticking or the circuit board isn't commanding it to function. Whatever the case it's night shift's problem now.

I spent some time yesterday putting a GPS tracker in a PacLease truck. Nice change from doing brakes and services to electrical work!

I'm really starting to like the VIS-Check machine...

I had the top of the van body swaying a good foot either direction and found the box moving on the frame rails just behind the cab (I think an extra set of u-bolts will remedy that problem). A lot of other stuff too... drag link, spring bushings, fan shroud rattles, rear axle u-bolts loose).

I'm learning the value of a good come-a-long and spud bar for changing suspension bushings... Someone welded in a solid tail on a dump truck but boxed in the torsion bars on the rear axle doing it. Had to unhook everything and roll the axle forward to get access. Also bent my favorite ratchet in the process (Now if only our Snap-On dealer could warranty things... Oh' well, we're supposed to have a new dealer next month).

Went on a road call on Saturday to the Best Western where I found this. Focus on what's not in this picture!

Some one stole the DPF's out of 2 Penske trucks parked overnight. Driver asked me if they'd let them across the border... Uh' no.

Almost looked like a fleet shop this week...

I'll be able to get my CDL though the company as they got their waiver endorsement now. Went on a road call to the Best Western on Saturday. That was interesting...

New things... Winter 2014

Started at Motor Trucks on the 23rd. First day was interesting as it was only me and Greg Kentch in the shop (Everyone else was on vacation or called in sick... Mighty convenient having a sick day the day before Christmas Eve). Started out with some recall and warranty work. Throttle pedals on T680's and sun shades on the International Prostar and Workstar trucks. Apparently the glue they used wasn't all that great and they had problems with them falling off. The fix was 8 rivets and sealant along the perimeter of the visor.

Been doing a few services and DOT inspections. Had a 4 axle dump trailer that steering locks on the drop axle weren't working. Found a broken wire at the junction box in the tongue of the trailer. The whole thing looked iffy so I replaced the whole box. Did some work on an '13 (I think) T800 that was in a wreck. New hood, radiator support, cooling package, bumper, etc...

Did brakes on one corner of this trailer. Not usual practice but in this case the driver runs with one brake backed off in the snow. The yoke pulled the threads right off the pushrod.

I really like the bushing tube setup for brakes... No need to pull the hub to do s-cams! Had this 2005 W900 in yesterday that failed every other line on the inspection form: bent tie rod, 2 nails in a tire, several tires at 70 psi, bad brake can, leaking hub seal, clutch out of adjustment, all the rear lights quit when the clearance lights are turned on, brake pedal sticks, multiple exhaust leaks under the sleeper, front cover leaks, trans output leaks, etc... You know what he wanted fixed? The low HVAC flow out of the vents.

Pulled the blower motor and found the linkage off of the re-circ door but everything else seems to be fine. The cab is moldy so I'll let someone else tear the interior apart and check out the vent ducts...

Learned how to use the VIS-check machine. Makes finding noises so much easier!

Back into hydraulics a little bit... Allison Automatic valve body and Ford IPR valve

What I've got from digging into these is that they are really not very complicated. All that makes that Allison (3060 I believe?) work are 6 solenoids and 4 ports. Clutch packs etc are the same as any other automatic and are somewhat familiar as I've been in a Ford AOD before.
