3 Adding Oil 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 oil level check plug as outlined above. (fig. C3496) 3 Remove the seat plate and front bulkhead assembly. 4 Remove the vented filler plug. (fig. C3845) 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 17 liters (4.5 gal). 6 Replace all plugs. Remove inspection cover C3668 IMPORTANT Check the final drives closely for damaged seals or other leaks if the oil level is excessively low.

Vented Filler Plug LUBRICATION 3.2 Checking The Oil Level Upper check plug Lower drain plug C3496 The loader has 2 independent final drive housings. When checking the oil level ensure the loader is on a level sur- face. 1 Remove the top (upper) check plug located between the 2 tires at the side of the loader. (fig. C3496) The oil level should be at the top of the check hole with a little to trickle out. WARNING C3496 Never work under a raised boom arm without the boom supports engaged and the engine shut off. Changing The Oil Ensure the loader is on a level surface before changing the oil. 1 Shut off the engine.

2 Slide a drain pan under one of the lower drain plugs located at the side of the loader, between the wheels. (fig. C3496) Be prepared to contain 17 liters (4.5 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. C3521) 4 Replenish the oil as outlined above in Adding Oil with 10W30 API classification SJ oil.

DRIVE CHAIN 3.3 Chain Inspection The drive chains should be inspected for wear or damage after the first 50 hours of operation and every 150 hours thereafter, or at any time the final drive inspection cover is removed. If the chain shows any sign of wear or dam- age replace it. (fig. C3769) Inspect as follows: Connection Link Sprocket 1. Inspect the chain for excessive roller wear 3 2. Inspect the chain for excessive wear on the link plates 3. Inspect the connection link cotter pins for wear or damage caused by interference. Cotter Pin Link Roller 4. Check the sprocket for excessive wear or damage such as broken teeth or sharp/rounded teeth. C3769 5.

If the chain is removed from the loader, check for stiffness caused by wear between the pins and bushings. 6. If the chain is removed from the loader, check that when laid out it runs straight and not to one side, indicating misalignment. 3-4
