Kohler K482, K532, K582, K662 Service Manual – Factory Torque Specs and Rebuild Procedures

Kohler K482, K532, K582, K662 Service Manual – 91 pages of factory-published data. Three decades turning wrenches in San Antonio has taught me one thing: if the torque spec is off by 5 ft-lbs on a K482 cylinder head, you are pulling the engine back out. Aftermarket manuals transpose numbers. This one comes straight from Kohler. You get the same document their dealership techs use.

Engine Reconditioning: Bores, Pistons, and Ring Gaps

Page 10.1 starts the Engine Reconditioning chapter. Cylinder block inspection, crankshaft specs for the K482, piston ring end gaps, connecting rod clearances. The manual tells you the wear limits in thousandths of an inch. Skip this section and you risk slapping a piston into an oval bore. The Inspection – Disassembly section on page 9.1 covers work area setup, what to look for on the cylinder walls, and the order to pull parts. Pay attention to the flywheel governor mechanism on page 10.5 – that plastic gear cracks if you pry wrong.

Fuel System and Governor – Factory Steps for K482 and K532

Carburetion starts on page 4.1. Automatic carburetors, fuel pumps (page 4.9), fuel filters (page 4.10). The Governor chapter splits: K482 governor on page 5.1, K532 and K662 governors on page 5.2. Different linkage setups. The manual gives you the exact spring hole positions and idle mixture screw turns. I’ve seen guys chase a surging idle for days because they used a generic adjustment from the internet. This manual puts a stop to that.

Does the Manual Cover Electrical Systems and Ignition Timing?

Yes. The Electrical Systems chapter (starting page 7.1) includes voltage regulator testing, ignition switch wiring, starting motors and drives, flywheel alternator systems. The Ignition Systems chapter on page 6.1 walks through operational test, spark plug gap, breaker points, ignition coil, condenser for the K662, and ignition timing for the K482. Timing is set with a dial indicator – the manual gives the degree specification BTDC. Don’t guess; use the procedure on page 6.8.

Understand the Wiring Before You Touch It

Wiring diagrams in this manual are factory-original. They show color codes and connector pinouts. Voltage regulator testing (page 7.1) requires a multimeter and the specific resistance values listed. If you rely on a third-party diagram, you might ground the wrong terminal and fry the regulator. Kohler’s schematic is correct. The Service Manual also covers the ignition switch circuit. Wire it wrong and the engine runs with the key off – seen that happen.

Torque Values on Page 14.3 – What You Get

Torque Values & Sequences for Fasteners lives on page 14.3. Cylinder head bolts, connecting rod cap screws, flywheel nut, closure plate bolts – all with ft-lb values and tightening sequences. The K482 uses a different sequence than the K662 because of the bore size. This page alone saves a rebuild. I keep a laminated copy in my toolbox.

Specifications and Tolerances – Critical for Rebuild

Page 14.1 lists bore diameter, piston pin clearance, oil pressure range, valve spring tension, and more. For the K482, K532, and K662 separately. Without these numbers you are assembling parts blind. The manual even gives run-out limits for the crankshaft.

Watch for the governor gear orientation when reassembling.

Common Questions About This Kohler Manual

Is this manual the same as the one Kohler dealerships use?

Yes. It’s the OEM factory manual.

Does it include torque values for all fasteners?

Yes, page 14.3 lists torque values and sequences for cylinder heads, connecting rods, flywheel, and more. That page alone saves you from guessing and stripping threads.

Can I use this for the K582 if I have a K532?

The manual covers all four models K482, K532, K582, K662. Each section specifies which model the procedure applies to. Pay attention to the governor section – K482 uses a different adjustment than K532 and K662. The specification tables at the end give bore, stroke, and tolerances for each model individually. So yes, you get coverage for all.

Does this manual include wiring diagrams?

Yes, the Electrical Systems chapter (starting page 7.1) covers voltage regulators, starting motors, flywheel alternator systems, and includes diagrams. It’s not a full vehicle wiring harness, but it covers all Kohler-sourced electrical components on the engine.

If your application uses a manual transmission, refer to Manual Transmission for background on gear ratios. Manual Transmission information can help you understand how engine torque affects driveline components. That said, this Kohler service manual stays focused on the engine itself. Access the Factory Manual and keep it on your bench — your wrenches will thank you.
