Checking The Engine Air Inlet And Exhaust System
Check all clamps, bolts, hoses and ducting on the engine air inlet and exhaust systems and service as necessary to prevent any leaks and to ensure that the air cleaner is securely mounted.
Checking The Diesel Fuel
Allow the machine to stand for at least 10 minutes before checking the diesel fuel. This will allow time for any water in the fuel to separate out.
Open the drain valve located beneath the fuel tank and drain at least one pint of fuel into a clear glass bottle and visually check for sediment and water. If sediment and/or water are present, drain fuel until it is clear. If excessive amounts of sediment and/or water are present, completely drain the tank and refill it with clean fuel.
Lubricating The Cutter Sheave Drive Shaft
Each of the slip joint drive shafts has two universal joints (U-joints) and a sliding spline section. Each U-joint has four bearings. All eight bearings and the sliding spline section must be properly lubricated if trouble is to be avoided.

To ensure proper lubrication of all four bearing assemblies in the universal joints, it is essential that lubricant be added until it appears at all journal cross bearing seals. This assures removal of dirt particles and other contaminants that may find their way into the bearings and indicates that the bearings are fully lubricated.
Do not assume that bearing cavities have been filled with new lubricant unless flow is noticed around all four bearing seals!
The journal cross seals are designed to relieve. However, if not all the seals "pop" when being lubed, move the drive shaft laterally in all four directions and pull or push on the drive shaft in the direction opposite to the journal cross seal not relieving, while lube gun pressure is being applied to the lubrication fitting. An increase in line pressure may also be necessary.
To ensure proper lubrication of the sliding spline section, apply grease gun pressure to the lubrication fitting until lubricant appears at the pressure relief hole in the welch plug at the sleeve end of the spline.
Then cover the pressure relief hole with a finger and continue to apply grease until it appears at the sleeve yoke seal.
