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.

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.
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
Mineral Base 75W, 75W-90, 120,000 miles 60,000 miles API GL-5 Gear oil, 75W-140, 80W-90 (193,000 km) or 1 year (96,500 km) or 1 year
MIL-PRF-2105E 85W-140 (whichever comes first) (whichever comes first)

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.
