It is nice too finally be back in class, summer quarter was fast and not a whole lot of hands on. So yes it nice to be back in class and listen to discussions and put my hands to work rather then just my brain.

In the first week of class there was a lot of discussion on doing voltage drop testing and finding parasitic loads using a volt meter and amp clamp. We also where shown how to do starting and charging system testing using a volt meter and amp clamp. after watching a few videos and watching Jeff show the whole class on a test board, I was feeling comfortable enough to go home and do a little testing on my roomates 1954 VW baha bug. Everything seemed to be in order except for the green death.

We also went over wire gauge sizes and looked at several different types of connectors and terminals. Below is a picture of some Weather Pack and Deutsch terminal testing leads I made in class. I was also able to practice crimping some battery cable ends.

I really enjoyed watching Jeff re-solder a circuit board for another students BMW. I have soldered many things but never a circuit board. Needless to say I think this is something I would like too and need to try.

Here we are the week before summer quarter begins and I am very excited to learn. I chose to take the Anaerobic Digestion class under Scott Stidham. In preparation and out of pure nerdy excitement I have been doing some research on Anaerobic Digestion and other things related. I had many basic questions about a week and a half ago and now I probably have even more; but here is a link to what I found to be some really good and easy to understand basic information on Anaerobic Digestion.   Anaerobic Digestion Basics


Along with the basic questions I had about Anaerobic Digestion I also wanted to have a better understanding about Cooling Towers and Water treatment and it's use in HVAC. This is think to another website that helped me answer some questions.   http://www.csiontheweb.com/water.htm


Looking forward next week and hope everyone's enjoying there internships, if not see ya next Wednesday.

Week - negative 1, summer quarter

For the final part of the spring quarter we were asked to do a Preventative Maintenance final project. We were to do a vehicle or equipment inspection/walk around. I chose to do mine on the 2011 Peterbilt.

I used a Preventative Maintenance Checklist For Tractors,Trucks, and Trailers. Here is the Link

It took me a good hour to just check off what was applicable. I have a pic of me doing the walk around and will post when I am able.

Final Project

1. I chose to do Lube Oils, Coolant, Service Intervals, and Grease.

Lube Oils-

Engine - ISX15 - 485/cm2250
Oil Type- CES20081 or CES20078 15-40w synthetic,
Capacity- 11 gal. or as stated by Cummins High 12 gal., Low 10 gal.
Service Interval- CES20081 at 15,000 mi. and CES20078 at 20,000 mi.

Transmission - Eaton - FRO-16210C
Oil Type- 75-90w synthetic, however Roadranger says to use Roadranger CD50 or an equivalent E500 synthetic.
Capacity- 7.57 L. or 16 pints, but It also said 26 pints I am a little confused on this.
Service Interval- check at 50,000 mi. and change at 250,000 mi.

Axles - Spicer - RDH49
Oil Type- 80-90w synthetic
Capacity- was not able to find.
Service Interval- fill as needed.


Coolant-

Type- RP329 (ethylene glycol) or RP330 (propylene glycol) in a 50/50 mix with water.

Capacity- 26.5 L
Service Interval- Check level daily, change coolant filter at 500 hrs or 6 months and flush at 2,000 hrs.

Grease-

Type- Lithium based
Capacity- varies
Service Interval- Daily
# of fittings I counted was, 51

I do have 4 or 5 pics of grease fittings in different spots, some hard to see and others so easy to see you might just miss looking for others. Will post when I figure out how to get the on my computer.

Here is the link I used to find the MSDS for lubricating oils, grease, and coolant.

Last but not least I want to thank everyone who has been a part of my learning and understanding of some basic and not so basic Electrical, Hydraulic systems and now PM. Spring quarter was fun and knowledgeable. Thank You Jeff.

Week 10
Total hours I really don't know, 180 lab/shop hours, another 150 spent online investigating.

This last week was Great! I spent most of the week either reading Owners/Operators Manual for the Bobcat  trying to understand what all was happening with the group assignment (travel motors,ETC.) or working with Logan on the Forklift transmission. Ending the week today with a trip down to Kenworth in Renton, this was awesome!

The group assignment went well. I feel that together as a group through our own individual research and group discussion we really came to understand what was going on with the travel motors from beginning to end. I know that without the teamwork and especially the class discussion I would still have a few questions.

Now the Forklift  transmission project I have been working on with Logan has gone good. We have finished cleaning almost all of the parts and have begun to reassemble the transmission. When it came time to put the retaining rings back in the clutch cylinders we had to fabricate our own tool to use in the 100 ton press in order to get the snap rings back on, this was fun. Can't wait to get back at it.

I ended the week today with a trip to Kenworth, wow. I was very impressed with what I saw today. Whole trucks being assembled in hours. I have never seen anything like that and left there in awe. Thanks again Tom and Jeff for making that happen.

Week 7
Hours 26

I Don't know why last weeks post(week 5) didn't get posted, I'm a little upset. I had a great week, It was absolutely awesome getting to go down to B&G Thanks Tom and Jeff. I had some good shop time on the Parker test bench and the dis-assembly and reassembly of a hydraulic piston pump(one of the pistons was broken).There was much more but I can't remember what I wrote.

Week 5
Hours 17-18

SPQ 13 Owen

Wow! A very busy week for me! A lot of life's surprises outside school made it tough for me to spend as much time in the shop as I would have liked too. However I did manage to finish the Cat Basics Hydraulics, get a little bit more simulator time, finished Parker test bench and had some serious fun on the Bobcat.

The Cat Basics Hydraulics was very straight forward. I felt pretty comfortable reading simple Hydraulic schematics, yet when it came time to tell the difference between pumps in parallel and series I had some trouble but Cat Basics worked it out for me and now I got it.

The simulator time I had this week was pretty little. The control familiarization is easy in practice but much harder in exam, its hard to tell the heights when moving the bucket up or down. It was also hard to get on due to others needing to use it as well, yet I could have spent more time when I was on. To be honest I don't like the simulator at all, but I guess I got to just get through it. I need to put more time in and just do it.

I had some great learning with a few others on the Parker test bench on Wednesday. I finished up 1-10 and then 10-15 for fun. I had a few small set backs mostly due to me not reading the questions right, oops. I really do enjoy when I can work with some one who is on the same page as me when it comes to completing a task. Thanks Logan!

Friday Fun Day, Friday was fun! I definitely understand the whole reason and technique behind silver soldering, Thanks Jeff and all the others for the discussion. The Bobcat, now that was fun. It has been about 5 years since I have really touched hydraulic controls, I was a little touchy at first, but all those years of running cranes/booms/blocks/launchers/windlass/winches and everything else on fishing vessels of several sizes and fisheries came running back. I was able to stack 7 out of 8 tires the second time on and that felt nice.

Week 6
Hours 17
Total  Hours 89

In week four I have spent a little bit of time on the simulator and hydraulic board, both interesting and frustrating. I decided I needed a little help with being able to read and understand hydraulic schematics and symbols. After spending quite a bit of time jumping from google images to different websites I did find some help. I ended up printing off some simple symbols chart and this has helped me " better" understand some schematics more so the couple I have looked at around the shop.

As far as the simulator goes I thought the practice walk around was pretty basic and the practice controls were pretty straight forward. I definitely need to spend some more time on it.

By the end of the week I had finished 4 of the fittings boxes  I for some reason started with 6,5,7 the hardest so far, I did box 2 today it was pretty easy. I really hope 1 and 4 ( the last ones) are as easy.

This week I didn't take any  hydraulic pump, valve etc. apart. I have in the past on boats to check for leaks or to clean. ( not saying I have a full understanding ) However I have never disassemble and reassemble a piston pump! If I can find one that is my objective tomorrow, along with some simulator time.
