Kohler LV680 Crankshaft F.A.Q.

What is the recommended oil type for the Kohler LV680 crankshaft?

The recommended oil type for the Kohler LV680 crankshaft is SAE 10W-30 for general use. Always check the manual for specific recommendations based on your operating environment.

How often should I change the oil in my Kohler LV680 engine?

It is recommended to change the oil every 100 hours of operation or annually, whichever comes first. Frequent oil checks are advised, especially in demanding conditions.

What are the torque specifications for the Kohler LV680 crankshaft bolts?

The crankshaft bolts for the Kohler LV680 should be torqued to 20-25 ft-lbs. Always refer to the service manual for precise specifications and procedures.

What is the procedure for replacing the crankshaft seals on a Kohler LV680?

To replace the crankshaft seals, remove the engine from the equipment, disassemble the crankcase, and carefully remove the old seals. Install new seals ensuring they are seated properly, then reassemble the engine.

How can I diagnose a knocking noise coming from the Kohler LV680 engine crankshaft area?

Inspect the crankshaft for wear, check connecting rod bearings, and ensure that the flywheel is properly torqued. Listen for specific sounds and refer to the service manual for further diagnostics.

What maintenance schedule should I follow for the Kohler LV680 crankshaft?

Regular maintenance includes checking and replacing oil, inspecting the crankshaft for wear or damage, and ensuring proper torque on all fasteners. A full inspection every 500 hours is recommended.

How do I align the crankshaft during reassembly of the Kohler LV680 engine?

Align the crankshaft by ensuring the timing marks on the crankshaft gear and camshaft gear are properly aligned. Use a feeler gauge to check clearances and adjust as necessary.

What could cause oil leaks around the crankshaft of a Kohler LV680 engine?

Oil leaks can be caused by worn crankshaft seals, excessive crankcase pressure, or improper gasket installation. Inspect and replace seals and gaskets as necessary.

How do I check for crankshaft straightness on a Kohler LV680 engine?

Remove the crankshaft and place it on V-blocks. Use a dial indicator to measure runout. If it exceeds the manufacturer's specifications, the crankshaft may need to be replaced or machined.

Can I use synthetic oil in the Kohler LV680 crankshaft system?

Yes, synthetic oil can be used in the Kohler LV680, provided it meets the specifications outlined in the owner's manual. Synthetic oil can offer better protection and performance in extreme temperatures.
