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

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 = 37,  total = 321
