ENGINE LUBRICATION SYSTEM
Oil pressure is affected by oil temperature, viscosity and engine speed. Subnormal oil pressures usually may be traced to a lack
of oil, a defective oil pressure control valve, loose connection in the lubrication system or worn bearings. The use of improper
viscosity oil will also produce low oil pressure shutdowns.
Engine Oil Change
The engine oil should be changed according to the Maintenance Inspection Schedule. Drain the oil only when the engine is hot
to ensure that all the oil drains out. When changing oil, keep the unit and trailer level so all the oil can flow from the oil pan.
1. Drain out as much of the oil as possible. Most of the dirt particles are found in the last few quarts of oil that drain out.
2. Refill the pan with oil and check the dipstick level.
• TK 482, TK 486 or TK 486V Engine: Add 12.3 litres of oil.
NOTE: See Specifications chapter for unit oil capacity and correct type of oil to use.
3. Operate the unit. Then recheck the oil level. Add oil as necessary to reach the full mark.
Oil Filter Change
The oil filter should be changed when you change engine oil.
Spin-on Filter
1. Remove the filter.
2. Apply oil to rubber ring of new filter and install filter.
3. Tighten the filter by hand until the rubber ring makes contact. Then tighten 1/2 turn more.
4. Start the unit and check for leaks.
NOTE: Do not use a tool to tighten the filter.
CRANKCASE BREATHER
The crankcase breather system ducts crankcase gases formed in the crankcase directly to the intake elbow. Harmful vapours that
would otherwise collect in the crankcase and contaminate the oil or escape to the outside, are now drawn back into the engine
and burned. The breather hose should be inspected to make sure it is not plugged during scheduled maintenance inspections.

TK 482, TK 486, TK 486V Engines
The crankcase breather includes a baffle, screen and cover located in the rocker arm cover. The crankcase pressure should be
between 0 and 50 mm H

O. Inspect the breather assembly and hose during scheduled maintenance inspections to make sure they
are not plugged or damaged.
