Lightly coat valve stems with a valve guide lubricant and install valve into valve guide. NOTE: Be sure valve guide lubricant is not on valve face, valve seat, or exposed end of valve stem. Drain oil from sump. Remove all rust, foreign material and burrs from crankshaft. Remove sump screws and remove sump and sump gasket. Place valve spring over valve stem. Place retainer on spring and with thumbs on retainer press on retainer to compress spring.
Compress spring until valve stem extends through large end of retainer slot. Continue to press until small end of slot can slide into groove on valve stem. Be sure retainer is fully engaged in valve stem groove. Install cylinder head on engine block. Set valve clearance. Inspect governor gear and bearing, flyweight pivots, and governor cup for wear or damage. Before installing sump, be sure that governor cup is in line with governor shaft paddle. Install sump and gasket being sure screw 9 has nonhardening sealant on the threads.
Tighten all screws using the pattern indicated above to Complete installation of remaining governor linkage and carburetor.
Adjust governor. The oil pump is driven by the lower end of the cam gear. This system does not supply oil under pressure to any of the bearings. This system only pumps oil to the oil filter and back to the crankcase for filtration purposes.
Drain oil from sump and filter. Remove all rust, foreign material and burrs from the bottom of the crankcase and the crankshaft. Remove the inner and outer rotors. Inspect surfaces of the rotors, pump housing, cover and shaft for wear and scoring. Inspect pump housing for debris. Clean as needed. Replace any worn or damaged components. If debris as found the sump should be removed for cleaning and replacement of the oil screen. This will prevent warping or breakage of the sump cover.
Using a punch through the slots in the oil pump housing, press the oil screen out of the sump. Press a new screen filter into the sump with the hole in the back of the screen oriented away from the governor shaft. Lightly coat the rotors with clean motor oil and install the inner then the outer rotor. Insert the o-ring into the o-ring groove in the sump and secure cover with the three screws.

Remove starter, cylinder heads and crankcase cover. NOTE: Remove any carbon or ridge at the top of the cylinder bore. This will prevent breaking the rings when removing the piston and connecting rod from the engine. Remove the connecting rod cap. Then push the piston and connecting rod out through the top of the cylinder. IMPORTANT: New piston rings must be installed whenever the engine is disassembled for major servicing or overhaul, providing that cylinder bores are within specifications.
NOTE: Measure cylinder bores before checking pistons and rings. If cylinder bores require resizing it will not be necessary to check pistons and rings since a new oversized piston assembly will be used. If cylinder bore is more than 0. IMPORTANT: When servicing pistons, rings, piston pins or rods, each rod, piston, piston pin and ring set must be kept as a set for the cylinder that it was removed from.
Mark each set before removing from the engine. To remove connecting rod from piston, rotate piston pin retainer until one end is exposed in notch in piston pin bore. With a needle nose pliers, grasp end of piston pin retainer and pull in and up to remove. From opposite side of piston, push piston pin out of piston and connecting rod. Piston pin is a push fit in piston and rod. Deposits may build up on piston. Spiral top oil control ring from oil ring groove into center compression ring groove.
Repeat into top compression ring groove, and then off piston. Repeat for bottom oil control ring. NOTE: If the cylinder is to be resized, there is no reason to check the piston, since a new oversized piston assembly will be used. If however, the cylinder is not to be resized and the piston shows no signs of wear or scoring, the piston rings must be replaced. Clean carbon from top two ring grooves. Place a new ring in each piston groove.
Insert old rings one at a time approximately Check end gap with feeler gauge. If ring gap is greater than 0. Never reuse worn piston rings. Wear gloves or cover rings with a rag. The top and bottom edges of the ring may be extremely sharp. Personal injury to hand could occur. NOTE: Before installing new piston rings, the cylinder bore should be reconditioned using a rigid hone with finishing stones.
This will restore the proper cross hatch angle in the cylinder bores. The correct cylinder cross hatch ensures proper lubrication and piston ring rotation. If the crankpin bearing in the connecting rod is scored, the rod must be replaced. Reject size of crankpin bearing and piston pin bearing is as follows: Specifications: Crankpin bearing. Piston pin bearing. Replace connecting rod if either bore is worn. If piston pin is worn 0. Reject sizes for piston pin and piston pin bore are as follows: Specifications: Piston pin.

Spiral oil control ring into top ring groove, then into second ring groove and into position over expander coil spring. Using ring expander, install center compression ring then, top compression ring as shown above. Projections Ring Compressor. The piston pin is a slip fit in both piston and connecting rod. Use a thin nose pliers or screwdriver and install a piston pin lock in groove on one side of piston.
Piston must be installed with notch or arrow toward flywheel side of cylinder. Dot on piston can face either direction. Insert piston pin from opposite side of piston until pin stops against piston pin lock. Then install other piston pin lock.
Be sure both locks are seated in grooves. Apply oil to piston rings, piston skirt. Place piston and ring compressor upside down on bench and push down until head of piston and edge of ring compressor are even. Tighten ring compressor until rings are fully. Then loosen ring compressor very slightly so that compressor can be rotated on piston skirt while holding connecting rod. NOTE: The pistons have offset piston pin bores. Position the notch or arrow on piston is facing toward the flywheel side of engine.
NOTE: Failure to use a torque wrench can result in loose connecting rods causing breakage, or tight connecting rods causing scoring. Rotate crankshaft two 2 revolutions to check for binding.
Rod should also be free to slide sideways on crankpin. Thoroughly clean and then oil cylinder bore. Rotate crankshaft until crankpin journal is at bottom of stroke. This permits complete entry of compressed rings, piston and rod assembly, when pushed into cylinder.
Clean and oil crankshaft crankpin. Pull connecting rod against crankpin. Install rod cap with match marks aligned. Install connecting rod screws and tighten to. Always inspect cylinder after engine has been disassembled. Visual inspection will show if there are any cracks, stripped bolt holes, broken fins or if the cylinder walls are damaged.

If cylinder bores are within specification and show no signs of scoring or other damage, new pistons rings may be installed providing the cylinder bores are reconditioned using a rigid hone with finishing stones. The proper cylinder cross hatch ensures proper lubrication and piston ring rotation. The cylinder finish, Cross Hatch should be applied after cylinder bore has been resized to within 0.
The finishing stones will produce the correct cross hatch necessary for proper lubrication and piston ring rotation. It is recommended that the cylinder bores be reconditioned to restore the cross hatch when new piston rings are to be installed in a cylinder that is within specification. Be careful not to hone oversize or it will be necessary to resize the cylinder.
NOTE: To produce the proper cross hatch finish use a drill speed of approximately rpm and 40— 60 strokes per minute. Lubricate hone liberally to prevent build up on finishing stones.
First wash the cylinder and crankcase carefully in a solvent such as kerosene or commercial solvent. Then thoroughly wash cylinder and crankcase using a stiff brush with soap and hot water, Rinse thoroughly with hot running water. Repeat washing and rinsing until all traces of honing grit are gone. Honing grit is highly abrasive and will cause rapid wear to all of the internal components of the engine unless it is completely removed.
When cylinder and crankcase have been thoroughly cleaned, use a clean white rag or napkin and wipe the cylinder bore. If honing grit is present it will appear as a gray residue on rag.
If any honing grit is evident, re-wash and rinse entire cylinder and crankcase and check again. When there is no trace of honing grit on rag, the cylinder is properly cleaned.
Then oil cylinder bore to prevent rusting. If this is done accurately, the service oversize rings and pistons will fit perfectly and proper clearances will be maintained. If a hone is used to resize the cylinder bore, place hone in middle of cylinder bore.
Tighten adjusting knob with finger until stones fit snugly against cylinder wall. Connect drive shaft to hone. Be sure that cylinder and hone are centered and aligned with drive shaft and drill spindle. Lubricate hone as recommended by hone manufacturer. The recommended drill speed is to rpm maximum and strokes per minute.
Because cylinder bores normally wear only in the area of ring travel, the cylinder bore will be round above and below ring travel. Start drill and, as hone spins, move it up and down at the bottom of the cylinder bore. Gradually increase the length of the strokes until hone travels full length of cylinder bore. Do not travel more than Lubricate hone frequently to prevent build up on stones. Check cylinder bore size frequently.
Check cylinder bores at top and bottom for burrs. Remove burrs. Cylinder head and crankcase cover surfaces must be free of burrs and gasket material. After cylinder bore has been brought to proper resizing dimension, a cross hatch must be applied to bore. If the cylinder bore is not within specifications, it will have to be resized using a boring bar or hone.
Always resize to exactly 0. Specifications: Standard bore size. Standard bore size. Flywheel should be inspected for cracks, broken flywheel fins, burrs on taper or keyway and distortion of keyway.

Use Proper Tools Use tools appropriate to the work. Makeshift tools and procedures can create safety hazards. Use power tools only to loosen threaded parts and fasteners. For loosening and tightening hardware, use the correct size tools. Avoid bodily injury caused by slipping wrenches. Use only service parts meeting John Deere specifications.
If you must work on a lifted machine or attachment, securely support the machine or attachment. Do not support the machine on cinder blocks, hollow tiles, or props that may crumble under continuous load.
Do not work under a machine that is supported solely by a jack. Follow recommended procedures in this manual. Lifting heavy components incorrectly can cause severe injury or machine damage.

Reduce pressure and spray at a 45 to 90 degree angle. Avoid breathing dust that may be generated when handling components containing asbestos fibers. Inhaled asbestos fibers may cause lung cancer. Illuminate Work Area Safely Illuminate your work area adequately but safely. Use a portable safety light for working inside or under the machine.
Make sure the bulb is enclosed by a wire cage. The hot filament of an accidentally broken bulb can ignite spilled fuel or oil. Components in products that may contain asbestos fibers are brake pads, brake band and lining assemblies, clutch plates, and some gaskets.
The asbestos used in these components is usually found in a resin or sealed in some way. Normal handling is not hazardous as long as airborne dust containing asbestos is not generated. Avoid creating dust. Never use compressed air for cleaning. Avoid brushing or grinding material containing asbestos. When servicing, wear an approved respirator. A special vacuum cleaner is recommended to clean asbestos.
If not available, apply a mist of oil or water on the material containing asbestos. Keep bystanders away from the area. Engine exhaust fumes can cause sickness or death.
If it is necessary to run an engine in an enclosed area, remove the exhaust fumes from the area with an exhaust pipe extension. If you do not have an exhaust pipe extension, open the doors and get outside air into the area. Gasoline engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
