Kohler K482 User Manual

Cylinder Heads: Remove spark plugs, then cylinder heads and gaskets.
Valve Mechanism: Remove valve covers then, using a spring compressor, remove taper
locks, rotators (if used), or spring retainers and springs. Carefully slip valves out of
guides. Tappets are removed most easily after camshaft and oil pan have been removed.
Gear Cover:
Remove capscrews to
block and gear cover, remove shroud mounting plate
(or blower housing support) first then gear cover.
On the
K662, remove breather com -
ponents from gear cover.
Front oil seal will be removed along with gear cover on the
K482 and
K532--slide seal off crankshaft first on K662.
Camshaft Gear: Wedge piece of wood between cam gear and crank gear then remove cam -
shaft retaining nut and washer. Cam gear is keyed to crankshaft -- use gear puller to
remove. Remove key from keyway after cam gear is pulled.
Cover Plate: Remove capscrews securing cover plate to block and remove cover plate
Camshaft: Rotate camshaft so that tappets are pushed away and will not interfere as shaft
is removed. Pull camshaft out through front end of block
-- carefully guide and support
shaft until completely removed.
If unsupported, it could fall when clear of bushings and
damage bushings and journals.
After camshaft is removed, tappets can fall inside crank
-
case when engine is tilted to remove oil pan. To prevent damage to tappets or other parts,
temporarily run a wire from adjusting nut on one tappet to the other
-- do this to tappets on
both cylinders.
Also tag tappets so that they can be reinstalled (if reusable) in same
cylinder during reassembly.
Oil Pan:
Tilt engine on its side to gain access to thru bolts securing pan to crankcase.
Remove thru bolts then, being careful not to damage oil screen, remove oil pan.
Tappets
can now be removed working thru inside of crankcase.
Oil Pump: After pan is removed, disconnect oil screen tube at body of oil pump.
Screen
must be removed from pump as it would
interferewith pump removal.
Remove capscrews
securing pump to crankcase and pull pump out through front of engine.
Connecting Rods
- Pistons: Working through bottom of crankcase, disconnect connecting rod
capscrews and remove rod caps. Tag these components
#I and #2 cylinder -- do not mix.
Carefully guide rod
- piston assembly out through head side of cylinder bore.
Temporarily
reinstall rod cap on piston
- rod assembly.
Crankshaft Gear:
Remove both snap rings
(K482, K532) then use gear puller to remove
crank gear (crank gear is light press fit on crankshaft
-- it may be possible to pry crank
gear off using two screwdrivers with large blades).
Remove key from crankshaft.
