LUBRICATION 3.2 Checking The Oil Level The loader has 2 independent final drive housings. When checking the oil level ensure the loader is on a level sur- face. 1 Remove any attachment, raise the boom arms and engage the boom support pins. Shut off the engine. 2 Remove the top (upper) check plug located between the 2 tires at the very front of the loader. (fig. C597) The oil level should be at the top of the check hole with a little to trickle out. Upper check plug Lower drain plug 3 Never work under a raised boom arm without the boom supports engaged and the engine shut off. C597 WARNING Adding Oil Remove inspection cover Oil should be added with the loader on a level surface.
1 Remove any attachment, raise the boom arms and engage the boom support pins. Shut off the engine. 2 Remove the small inspection cover located to the rear of the steering lever. (fig. C2024) 3 Remove the oil level check plug as outlined above. (fig. C597) 4 Remove the vented filler plug. (fig. C2038) 5 Add 10W30 API classification SE/CD oil until it begins to flow out the upper check hole. Total final drive housing capacity per side is 7 liters (1.9 gal). 6 Replace all plugs. C2024 Chain check / oil filler plug Check the final drives closely for damaged seals or other leaks if the oil level is excessively low.
IMPORTANT Changing The Oil Ensure the loader is on a level surface before changing the oil. 1 Remove any attachment, raise the boom arms and engage the boom support pins. Shut off the engine. 2 Slide a drain pan under one of the lower drain plugs located at the front of the loader, between the 2 front wheels. (fig. C597) Be prepared to contain 7 liters (1.9 gal) of oil. 3 Remove the drain plug. Allow the oil to drip com- pletely out of the final drive housing. Replace the drain plug . Dispose of the waste oil in an environmentally friendly manner. If the oil is contaminated, remove the side inspection cover to flush the housing. (fig.
C2073) 4 Replenish the oil as outlined above in Adding Oil with 10W30 API classification SE/CD oil. C2038 Final drive inspection cover C2073 3-3

DRIVE CHAIN 3.3 Checking The Drive Chain The drive chain must be checked for adjustment after the first 50 hours of service and every 150 hours thereafter. Correct chain tension must be set to 1/4 to 3/8 inches (6 to 9mm) free play. 1 Remove any attachment, raise the boom arms and engage the boom support pins. Shut off the engine. 2 Remove the small inspection cover located to the rear of the steering lever. (fig. C2024) Remove inspection cover 3 C2024 3 Remove the vented filler / check plug. (fig. C2038) Chain check / oil filler plug C2038 4 Check the chain tension using the special tension tool P/ N 960997.
Slide the special tool into the filler hole and use the hooked end to grab under the chain. (fig. C372) Pull upward on the tool using a force equal to approxi- mately 30 lbs (13.6 kg) pull. The special tool is calibrat- ed in 1/4 inch increments. (6mm) Correct adjustment is calculated by the number of marks the special tool moves. The special tool should only move 1/4 to 3/8 inches (6 to 9mm) at a 30 lbs (13.6kg) pull. Replace the plug if no further adjustment is required. 5 Apply a thread sealant to the inspection / fill plug before replacing. (fig. C2279) C372 Apply thread sealant to plug C2279 3-4
