This week I replaced a spindle and steering arm on a 2009 new Holland t4030 tractor. The steering arm and spindle were starting to get a lot if slop in them where they bolt together and this tractor only has 2500 hours on it. The only reason that I can think of why this happened is because that was the side that has the hydraulic cylinder connected to it for the steering. So my guess is that the pushing and pulling from the steering cylinder puts a lot of strain on those parts. This type of tractor also doesn't seem like it was designed to see real use on a farm and seems more like it was made to be a hobby tractor. These tractors certainly aren't made like they used to make the old fords.

This week I got to rebuild some brake calipers on a Volvo A30D haul truck. This is something that takes patience to do to get the inside of the calipers cleaned out of any rust that builds up in them.

This week I got to help replace some of the leaf spring equalizers and the equalizer mounts on a four axle pup trailer. The trailer was originally in the shop for new s cams on two of the axles and new slack adjusters on all four axles. Then we noticed a crack on one of the equalizes so we looked them all over and found three of them had cracks on them. Changing the eqaulizers was a fairly smooth process. We just had to remove a couple of the tires to get the leaf springs to hang down far enough so that we could slide the new parts right in.

This week at interwest construction I went around to some of the companies job sites with the company's oiler. The oiler's job is to put diesel in all the equipment at job sites and he also greases all the equipment when it gets filled with diesel. He also check the oil, coolant, and hydraulic fluid on the equipment and fills them when necessary. The oiler is also responsible for field servicing equipment at 250 hours, this includes oil change, oil filter, and fuel filters, he also services all the trucks at the shop. The oiler position requires you to have a class B cdl and a hazmat endorsement for hauling fuel. This was an interesting position to learn about and to get a chance to see all the equipment that the company has.

This is an 1987 International S2300. It has an L10 Cummins, a RT-11609A Eaton Fuller transmission, Spicer rear axles and uses a walking beam rear suspension. This truck has 48 zerk fittings on it, 6 of which are on the dump hoist. The hardest zerks to find on this truck are on the transmission cross shaft, throw out bearing, clutch linkage, and there is on inside the cab for the steering linkage. Special care should be taken when greasing the dump hoist as it has to be raised up to grease all the zerks. The wet kit has a total fluid capacity of 1530ci and is filled with ATF.


The L10 cummins has an oil capacity of 8 gallons/32 quarts. It is filled with 15w-40 motor oil

This is Cummins recommended maintenece schedual
https://quickserve.cummins.com/qs2/pubsys2/xml/en/procedures/173/173-102-002-om-prix13.html?q=recommended service intervals

The use of quality engine lubricating oils, combined with appropriate oil drain and filter change  intervals , is a critical factor in maintaining engine performance and durability.

Cummins Inc. recommends the use of a high-quality 15W-40 multiviscosity heavy-duty engine oil that meets the requirements of Cummins Engineering Specification CES 20071 or CES 20076 (such as Valvoline® Premium Blue® or Premium Blue® 2000). American Petroleum Institute (API) specification CH-4 can be used as an alternative to CES 20071. Oils that meet API specification CG-4 can be used, but at a reduced drain interval according to the Oil Drain  Intervals  by Severity of  Service  mi [km] chart listed in Section 2. The oil grades CC, CD, and CE have been obsoleted by API and should not be used.


RT-11609A transmission. This transimission has a fluid capacity of 13 liters. Eaton recommends using heavy duty engine oil to fill the transmission, SAE 50 (HD engine oil), MIL2104H, Cat TO-4 (SAE 40- SAE 50). The transmission oil should be changed every 60,000 miles or 1 year.

Roadranger Lubrication Philosophy
In promoting component reliability and longevity, proper lubrication is the key to a sound and effective maintenance program.
Without effective lubricants at proper levels, remaining maintenance procedures will not keep components functional.
We believe synthetic lubricants have proven to be superior to petroleum products and represent opportunities to promote superior
maintenance and bottom line operating performance while significantly extending component service life and reliability.
Certain products and applications, as noted in this manual, require the use of approved synthetic lubricants.
A list of approved lubricants and suppliers can be found at www.roadranger.com in the approved Lubricant Supplier Manual,
TCMT0020.
It is important to perform a daily pre-trip inspection of drivetrain components for lubricant leaks. Leaks should be brought to the
attention of maintenance and immediate corrective action should be taken.

Check Transmission Oil Level
Note:
Before checking level, engine must be idling in neutral
for at least 2 minutes and lubricant temperature must
be between 60° and 120° F [15.5° and 48.8° C].
Check lubricant level using the fill hole or sightglass usually
located on the right side of the transmission. Inspect oil filter
for leaks, rust or damage. Replace as necessary.
Check fluid levels and inspect for leaks at regular PM maintenance
intervals, not to exceed 12,000 miles.
1. Turn engine off.
2. Remove fill hole plug.
3. Lubricant must be level with the hole.


The drive axles are marked Hayes-Dana inc which is a spicer axle. The drive axle should be filled so that the fluid is at the bottom of the hole on the fill hole

This week I tested the pressure relief of the pilot system on the mini excavator. The first thing that you have to do is get the hydraulic system up to temp by moving the hydraulic controls around. Then you hook a pressure tester up to the test port on the excavator and then holding one of the control levers all the way over till the hydraulic cylinder for that function is all the way in or out and then you keep holding it so the pilot system builds up enough pressure to have to bypass and you are able to get your pressure reading.

This week in class we cut open a few oil filters to see what they looked like inside. So I decided that I was gonna take apart a few of my own. I had two old oil filters from my car laying around so I cut them open. One filter was a fram filter and the other was a napa filter. I was very interesting to see the differences of what the filters look like inside of them and how they are made. I think that for my next oil change I am going to get a filter from Honda so I can cut it open to compare what it looks like next to one of the other filters.

This is the napa filter. It has metal end caps and is a non bypass filter. I didn't find anything wrong with the filter media and no shiny metal pieces so that's good

This is the fram filter. It has a gasket material for the end caps and is a bypass filter. It uses a metal clip, instead of glue, to hold the filter media together. It is slightly longer than the napa filter.

The bottom of the napa filter on the left and the fram on the right. I am not sure that I like how the fram filter is a bypass filter.
