INSTALLATION INSTRUCTIONS INTRODUCTION This manual includes information pertaining to the standard features of each Universal Service Engine and instructions for modifying or converting the engine to fit numerous applications. The chart on the opposite page lists the main application features of the engines--use this as a guide and refer to the appropriate instructions on the following pages whenever the notations are applicable, as this may be especially important to the successful installation of your engine. Before placing your Universal Service Engine in operation, make special note of the RUN-IN recommendations on the last page of this instruction.
AIR INTAKE All Universal Service Engine versions include dry type air cleaner which, in most cases, can be used even though the engine being replaced has another type. Transfer intake elbows when used. If engine being replaced has an oil bath air cleaner and it is deemed necessary to retaj.n this type, transfer the oil bath air cleaner, brackets, etc., to the Service Engine and install in place of the dry type. Make sure the oil bath air cleaner is properly serviced before being used.

BAFFLES & SHROUDS All Universal Service Engines furnished with baffles and shrouds for induced air cooling system. On this type system, cooling air is pulled thru the air intake screen into the blower housing by fins on the flywheel then forced past cooling fins on block and cylinder head and finally expelled toward the PTO end of the engine.
CARBURETOR Universal Service Engines equipped with side draft type gasoline carburetor less fittings and fuel lines--transfer these items from the engine being replaced. Carburetors are adjusted to normal settings in the factory; however, readjus tment may be needed to suit local conditions--to make final adjustment, allow engine to warm up then while operating at full load and speed (when possible), turn the main fuel screw in until engine slows down (too lean) then turn screw back out until the engine again starts to slow down (over rich setting) then set main fuel screw halfway between these two positions. Rough idle is usually caused by the idle speed being set too low- -turn idle speed screw clockwise to increase idle speed. If rough idle persists after readjusting idle speed, turn the idle fuel adjusting screw in or out 1/4 turn at a time until smooth idle is attained. The initial setting of the main fuel screw is 2 turns open and the idle fuel is initia lly set at 1-l/4 turns open . Use these as starting points if readjustment is neces sary.
CRANKCASE A 11 Dniversal Serv ice Engines feature Dynam ic Balance for smooth, virtually vibration free operation. This includes two counterwe ighte ears on stub shafts inside the crankcase. The gears are driven off a gear on the crankshaft and are ed to offset the reci procating forces of piston and crankshaft counterweights to minimize vibratto . The main difference in crankcases is in pilot size and bolt circles- -refer to the illust ration above for pecific bolt circles and pilot details.

Attach the retractable starter to blower housing with five X- 50-8 mounting screws and X-22-22 washers--do not tighten screws at this time. To align starter, pull handle out about 8" so that dogs engage in the drive cup--hold handle in this position while completely tightening the five mounting screws.
STEP 6 :
Peel the backing off the special "write-on" nameplate (included in literature pack) and attach this to the blower housing. Paint engine if desired then peel painting mask off the nameplate. Use a ball point pen to write the Model, Specification and Serial numbers of the Service Engine (found on nameplate of blower housing removed in Step 1) on the special nameplate. These numbers must stay with the engine for parts ordering purposes.

RUN-IN RECOMMENDATIONS Each Service Engine is test run on a special "break-in" oil in the factory. Further use of special "run-in" or non-detergent oil is therefore not required to seat piston rings. Oils meeting the requirements of SAE service class SC, SD, SE and SF are recommended for use in Kohler engines. Select oil viscosity based on the air temperature at the time of operation, as shown below: AIR TEMPERATURE
OIL VISCOSITY
Above 32° F coo C) BeloK 32° F COo C)
SAE 30 SAE 5\1120 or 5W30
Use straight Keight oils as specified . DO NOT use multi-viscosity oils above 32° as considerable increases in oil consumption and combustion deposits will result. OIL CAPACITY: Add 1-1/2 quarts of oil initially, then check level on dipstick--add oil only as necessary to bring oil level up to the "F" mark--DO NOT exceed this mark. K321A Spec 60272 engines hold 1-3/4 quarts--all others have capacity of 2 quarts. Run-in new engine under load to further promote seating of the piston rings. Change oil after the first 5 hours of operation. Thereafter, change oil at 25 hour intervals. If extremely dirty or dusty conditions prevail , change oil more frequently.
