Grease fitting count:

After about 10 different times of counting, and some help from other classmates, I have come to the conclusion that there are 51 total grease fittings on the Peterbuilt. I had several different outcomes from counting from 43-49. I finally realized there are 51 fittings when I saw that there was a fifth universal joint... once again, it is always the simple things that get me.

It would be really nice if all grease fitting locations were this simple :

Peterbuilt Inspection:

While inspecting the Peterbuilt we found several things that were amiss. first off was one of the tires on the drop axle was completely worn, holes everywhere, and in really bad shape.

Another thing that was noticed was that the leaf springs on the driver's side of the rear suspension were loose

and off center.

Also, when we put the truck in reverse, the backup alarm did not sound off, and the back up indicator lights did not turn on.

Raul Soto pointed out that the tie-rod clamps on the front axle were not properly positioned. They are supposed to be pointing down: 

We also found that the "glad hands" (the piece that provides the trailer with air) had cracking seals: 

 

Another thing was that the air tanks had not been bled for a while so there was A LOT of water that came out when we bled them. It sprayed everywhere. Here's some of the aftermath of the spray:

The power steering pump has a leak on the supply line. Here's a picture of the leaking line: 

On a side note, this is a vein pump. I took one apart a few weeks ago. It looks exactly the same as the one I took apart.

The clutch pedal mechanism needs to be adjusted, when the pedal was pressed, it didn't fully release which could cause major failure.

Overall, I would put this truck out of service until the repairs were made.

Reflections on the Preventive Maintenance course:

This course has actually been really eye-opening. It makes complete sense to me that things need to be service regularly, but I hadn't ever considered that before. I would always think it was time to fix something after it had already broken. I am certain that knowing what I know now will save me hundreds of headaches in the future (also lots of money). I have even been trying to show my family the benefits of preventive maintenance! I will always now remember the "golden rule" of preventive maintenance: Short term costs for long term savings. And another good rule: If it ain't broke, do the work to keep it that way.

What a fantastic quarter!! I have learned more than I could have ever imagined!

Gear Oil:

The type of transmission in the Peterbuilt is an Eaton Fuller Fro-16210C 10-speed 2-reverse.
the recommended oil for this transmission is Eaton Roadranger CD-50

You can find the MSDS for this oil at this website: http://www.roadranger.com/rr/ProductsServices/ProductsbyCategory/Lubricants/index.htm

You can find the link to the MSDS on the mid-lower right hand side of this web address under "Service/Treoubleshooting" listed as "MSDS SAE 50 transmission fluid"

Here is what the service manual for this transmission says about lubrication:

Lube Oil:

According to the sticker located on the frame of the Peterbuilt, the engine was factory filled will 11 gallons of Chevron Delo 400 LE SAE 15W-40.

 In the ISX15 engine owner's manual, it is suggested that the oil to be used is Valvoline sythetic with the same SAE 15W-40. I wonder why they chose to not use the recommended brand... food for thought.

Here is a link to the MSDS for the specified oil: https://cglapps.chevron.com/msdspds/MSDSDetailPage.aspx?docDataId=302386

Here is what the manufacturer had to say about this oil:

" Delo 400 LE SAE 15W-40 (API CJ-4)

Delo 400 LE SAE 15W-40 is formulated to meet the requirements of post-2007 low emission engines equiped with advanced emission control technologies. Provides outstanding performance with Ultra Low Sulfur Diesel and also with normal and low sulfur diesel fuels, Delo 400 LE is backward compatible and may be used in older, conventional engines and gasoline engines.

Coolant:

Cummins recomends Fleetgaurd Compleat ES premixed 50/50 as the proper anitfreeze for the ISX15 engine on our Peterbuilt. Here is a link to the MSDS
http://www.cumminsfiltration.com/pdfs/MSDS/MSDS_Europe/LT16587GB.pdf

I found that this was the recomended coolant when I looked in the ISX15 CM2250 owner's manual. The service interval for this coolant is 150,000 miles. Also, here is a link to what Cummins has to say about this coolant. http://www.cumminsfiltration.com/html/en/products/cooling/coolant/es_compleat/es_compleat.html

The recommended coolant filter is a Fleetguard WF2126. You can find this filter scrolling down to the ISX15 Filtration package at this website: http://www.cumminsfiltration.com/pdfs/product_lit/americas_brochures/LT36159.pdf

Hydraulics...

First off, I apologize for not posting for a while.

These past few weeks of working through hydraulics have been extremely educational! I went trough several boxes of pipe fittings and hose fittings trying my best to identify them. Though, I still could use some more practice. Our class rented a Bobcat E32 Excavator, we have been going through the service manual and looking over the hydraulics schematics which has been pretty great! I have learned a lot by having the machine here to match symbols on the schematic with the parts on the machine. I had trouble with finding out what a certain hose was that was just hanging off the side of the machine, it wasn't on the schematic but after some digging into the service manaul (and a few hints from Jeff) I soon realized that this elusive hose was clearly the drain hose. Oh well, we all have our moments right?

We were assigned into groups to isolate certain hydraulic circuits in the schematic and find them in the machine and explain to the class how it opperated. My group chose the pilot system. We found the opperating pressure of the oil in the service manual and tested it at the test point located on the manifold of the pilot system. Our results ranged from 415-450psi depending on what the engine speed was set to (turtle mode, and rabbit mode.)

For the hydraulic final, we needed to find what the service manual said about the cycle times of the functions like boom raise, bucket curl, blade lift, etc. I chose to do bucket curl. In the sevice manual it states that the cycle time for the bucket curl is 2.7 seconds, when I tested it the time turned out to be 2.3 seconds. I am not sure as to why it was faster then specified in the manual. I will include a video of this test in this post.

Another part of the final was to prove speed of the tracks by counting the number of revolutions made in one minute. The service manual states that the tracks move at 2.9 mph which equates to about 17.7 revolutions per minute have a track length of 14.416ft. When we ran the test we counted the revolutions per minute and we got 19 which equates to 3.1mph. I think if was faster than specified because there wasn't any load on the tracks, we had the tracks lifted up on one side.

We recieved a worksheet that asked the question if we could complete oil flow test sheet for the Bobcat with the same meter we used testing the flow on the winch and windlass from the boat. my answer is, no we couldn't because one of the tests required a gauge that could handle 345 bar and 5000psi. The flow meter we had only goes up to 240 bar and 3000psi.

We will be moving on to preventative maintenance now before the end of the quater. I think it will go over how to keep your equipment in good working order for as long as possible. With that in mind, I should probably go change the oil in my car...

Hydraulics: Week 1...

Starting off with hydraulics this week, I felt as in over my head as I was with electrical systems. Though, it was really cool to take apart a bent-axis hydraulic piston pump, and see how it functioned. I did some of the CAT simulater exercises and that was pretty tough. I am usually pretty good at video games, but this simulater really kicked my butt. Overall, another fantastic week.
