engine until the coolant temperature reaches
60°C (140°F). Shut off the engine.

Clean the area around the lubricating oil filter
head, 1. Remove the filter, 2.
NOTE: All model tractors use one single oil
filter mounted on the right-hand side of the
engine.
Clean the sealing surface of the filter head. The
O ring may stick on the filter head. Make sure it is
removed.
Using the correct oil filter for your engine, fill it
with clean engine oil. The lack of lubrication
during the delay until the filter is pumped full of oil
is harmful to the engine. Apply a light film of oil to
the gasket sealing surface before installing the
new filter.
Install the filter on the filter head. Tighten the filter
until the gasket contacts the filter head surface.
Tighten the filter an additional 1/2 to 3/4 of a turn.
NOTE: Over-tightening can distort the
threads or damage the filter element seal. Do
not use tools to tighten the filter.
Clean and check the oil drain plug threads and
the sealing surface. Install and tighten the oil
