Fq 2013

So I successfully found the key off parasitic drain on the peterbilt... I have to say I found quit a bit of difficulty when I tried to use the same tactics I used on the international. I found it by checking the load on the fuses. Then used my meter to check the outlet (where the fuse box lead me). The outlet had no power so I pulled covers off and found a damned resistor behind the ash tray.       Hours this week:15.                                 Hours total:40

FQ 2013

This week was my first week back in class. It was intimidating at first because summer had taken its toll on my memory but for the first day we did a great exercise and brushed up on all the things the class I felt fuzzy about; connecting to the vehicles computer and deciphering codes, finding a short to ground, short, open and properly testing a battery. I have already tackled the key off parasitic drain problem on the shop's international. I am pretty comfortable with the amp clamp now and I doubt I will have too much problems (knock on wood (excluding extenuating circumstance)) finding the root of a parasitic drain. I also learned how to crimp connections on both large and small wires.

Hours this week and total: 25

SPQ2013 Final

This is my preventative maintenance final project; Jeff has required us to pick a vehicle to inspect and document. Down below I have found the factory specifications.

During this portion of class I have learned a lot about the importance of P.M. If the time is not taken to properly care for the vehicle not only is there a shorter vehicle life but possible down time which can cost a lot of money.

*Lube oil serves to remove heat from where it’s generated, preventing gearing component temperatures from rising to excessive levels, it also transfers or removes wear particles and any other undesirable contaminants. Failure to lubricate you system WILL result in premature system failure.

Maintenance intervals

General Information

TOC

Automotive Applications Perform maintenance at whichever interval occurs first. At each scheduled maintenance interval, perform all previous maintenance checks that are due for scheduled maintenance. Maintenance Procedures at Daily Interval(1) Air Cleaner Restriction - check Air Intake Piping - check Air Tanks and Reservoirs - drain Coolant Level - check Charge-Air Piping - check Crankcase Breather Tube - check Drive Belts - check Fan, Cooling - check Fuel-Water Separator - drain Lubricating Oil Level - check Aftertreatment Exhaust Piping - check Diesel Exhaust Fluid (DEF) Level - check Maintenance Procedures at 40,000 Kilometers [25,000 Miles], 800 Hours, or 6 Months(1) (3) Pressure Fuel Filter - change Fuel Filter Suction - check Lubricating Oil and Filters - change Radiator Pressure Cap - check Supplemental Coolant Additive (SCA) and Antifreeze Concentration - check Charge-Air Cooler - check Maintenance Procedures at 80,000 Kilometers [50,000 Miles], 1500 Hours, or 1 Year(2) Air Compressor Discharge Lines - check Air Compressor Air Cleaner Element - check Air Leaks, Air Intake and Exhaust Systems - check Cooling Fan Belt Tensioner - check Coolant Filter - change Engine Wiring Harness - check Maintenance Procedures at 200,000 Kilometers [125,000 Miles] or 3000 Hours(5) Crankcase Breather Element - change Maintenance Procedures at 200,000 Kilometers [125,000 Miles], 3000 Hours, or 2 Years Radiator Hoses - check Cold Starting Aid - check Radiator Shutter Assembly - check Vibration Damper, Viscous - check Engine Mounting Bolts - check Engine Steam Cleaning - clean Maintenance Procedures at 241,000 Kilometers [150,000 Miles] or 4500 Hours Aftertreatment Fuel Injector - clean Maintenance Procedures at 320,000 Kilometers [200,000 Miles] or 4500 Hours(4) Aftertreatment Diesel Particulate Filter –  replace or clean Aftertreatment Diesel Exhaust Fluid Dosing Unit Filter - change Maintenance Procedures at 400,000 Kilometers [250,000 Miles], 6000 Hours, or 2 Years Cooling System - flush Maintenance Procedures at 800,000 Kilometers [500,000 Miles], 10,000 Hours, or 5 Years (6) Engine Brake Assembly - test Fan Hub, Belt Driven - check Overhead Set - adjust The lubricating oil and lubricating oil filter intervals are based on Cummins® Engineering Standard 20,081 and a normal duty cycle. Oil change intervals can be adjusted based on fuel consumption and whether or not the oil meets Cummins® Engineering Standard 20,081. See the Oil Drain Intervals Table for Severe Duty and Light Duty drain intervals in this section. Follow the manufacturer's recommended maintenance procedures for the starter, alternator, generator, batteries, electrical components, engine brakes, exhaust brake, charge-air cooler, air compressor, air conditioner compressor, and fan clutch. Test the SCA concentration level every 6 months unless the concentration is over three units; then check at every oil drain interval until the concentration is below three units. Use the following procedure for coolant condemnation limits. Refer to Procedure 018-004 in Section V. The aftertreatment diesel particulate filter intervals can be adjusted, based on the type of engine oil that is used. See the Aftertreatment Cleaning Intervals table for cleaning intervals. While air cleaning is allowed, the Cummins Inc. preferred method would be to exchange the DPF at the recommended maintenance interval. The crankcase breather element intervals can be adjusted, based on engine blowby. See the Crankcase Breather Element Change Intervals table below. The components of the engine brake that are subjected to wear during normal operation of the engine are available as a kit through Cummins® Inc. Distributors/Dealers. It is recommended to do this maintenance at 800,000 km [500,000 mi], 10,000 hours, or 5 years. All EPA 07, EPA 10, EPA Tier 4 Interim/European Union Stage IIIB 2011(174 -751 hp) engine systems equipped with exhaust aftertreatment must operate on ultra-low sulfur diesel (ULSD) with a maximum sulfur content of 15 ppm in the United States and 10 ppm in the European Union. Failure to do so can permanently damage engine and aftertreatment systems within a short period of time. This damage could cause the engine to become inoperable and affect the warranty coverage on the engine system. Aftertreatment Cleaning Intervals Oil Classification Kilometers/miles Hours CES20081 320,000 [200,000] 4500 CES20078 241,000 [150,000] 4500 Crankcase Breather Element Change Intervals Engine Blowby Interval Less than 305 mm-H2O [12 in-H2O] 200,000 km [125,000 mi] or 3,000 hr Greater than or equal to 305 mm-H2O [12 in-H2O] 120,000 km [75,000 mi] or 1,500 hr

Also I found 49 zerk fittings on the Peterbilt here are some pictures of the ones I almost missed.

SPQ2013

This week we had a guest speaker, he lectured us on Kenworth trucks, specifically the wiring faults that they found in their trucks to aid us in future trouble shooting.
I also dis-assembled a piston pump but it turned out to be gutless so I researched it and learned how a piston pump works so... no waist there. And I spent some more time on the caterpillar simulator. Today we made the transition into preventative maintenance and we have been getting the importance of it drilled into our brain for the past few days of class.

Oh! and the axle popped out of my car again and guess what? it was a quarter of an inch too short "THANKS NAPA" anyways that sucked but got it fixed and shes back on the road.

Time this week: 28

SPQ2013

I took my final yesterday. I learned how to find the rpm for the moving parts and prove it both mathematically and physically as seen here in these videos.

SPQ2013

This week I learned how to cut open and oil filter. I also started making my way through caterpillar basics Troubleshooting portion. I began on our new hydraulic testing assignments on the bob cat excavator, I am really  starting to get used to finding things in the manual. also my cars CV axle popped out once again will we were getting on the freeway after a long day. we ended up towing it back and we went to the parts store today hoping that it would be open but nope.... tomorrow i guess.
