VALVE CLEARANCE
ADJUSTMENT
Adjust the valve clearances when the sound of the tappets is
loud or when the engine does not run smoothly.
Adjust the valve clearances by loosening the lock nut (B), the
adjusting screw (A) using a screwdriver and then applying a
thickness gauge (C). When locking the adjusting screw by
means of the lock nut (B), support the adjusting screw firmly
using a screwdriver so that both are not rotated together.
Valve clearance: Intake & Exhaust 0.25 mm cold condition.

3.
Then rotate the crankshaft 240 deg. clockwise to move1 the
piston of No. 3 cylinder to top dead center on compression
stroke, and adjust its valve clearance.
4.
Then rotate the crankshaft 240 deg. clockwise to move1 the

1.
The valve clearance should be checked with a cold engine
and with the piston at top dead center on the compression
stroke.
The top dead center on the compression stroke of No. 1 pis-
ton can be determined by the timing marks on the crank pul-
ley and timing gear case.
2. Position the piston in No. 1 cylinder at top dead center on
compression stroke and adjust its intake and exhaust valve
clearance.
The air cleaner element, when remarkably stained or clogged,
may prevent smooth start of the engine or deteriorate its per-
formance, preventing normal operation. Keep the element
always clean to ensure full performance of engine.
As known the air cleaner filters the intake air.
Air cleaners used
are mostly the types that are composed of 2 nested papers.
These elements keeps 99.9% of the dust in the air. Depending
on the operation conditions of the tractor, the element gradual-
ly becomes stained as operation hours increase.
Air cleaner must be checked daily, sealing must be checked
and when clogged the element must be cleaned by blowing 5-
6 bars compressed air to inside of it,
And then it must be
installed ensuring that it is free of ruptures or holes. Sealing
gasket is checked, it may be reused after washing with water
and drying under shade. If it is not clean enough, you must
replace it.
