BRIGGS & STRATTON 798813 Engine Connecting Rod maintains proper piston-to-crankshaft movement for consistent engine operation. Common connecting rod wear or damage can affect engine function.

This part corrects the following symptoms:

• Engine knocking noise.

• Excessive engine vibration.

• Reduced engine compression.

• Piston movement problems.

• Internal engine damage.

Engine Knocking Noise

Quick Check: Listen carefully during engine idle for repeated knocking sounds.

Fix Suggestion: Tighten connecting rod bolts using specified engine torque values correctly.

Prevention Tip: Change engine oil regularly preventing excess internal component wear.

Reduced Engine Compression

Quick Check: Measure cylinder compression using an appropriate gauge before engine disassembly.

Fix Suggestion: Inspect the connecting rod and piston connection for wear or damage that may affect proper piston movement.

Prevention Tip: Maintain proper lubrication reducing excessive connecting rod surface friction.

Piston Movement Problems

Quick Check: Rotate crankshaft manually observing smooth piston travel without binding.

Fix Suggestion: Align rod cap correctly before securing all fasteners into position.

Prevention Tip: Avoid engine overspeed minimizing stress across connecting rod components.

Internal Engine Damage

Quick Check: Look inside crankcase for damaged rod surfaces or fragments.

Fix Suggestion: Inspect related engine components for damage and remove debris before installing a replacement connecting rod.

Prevention Tip: Monitor unusual engine sounds preventing extended operation after abnormal noises.

Customer Experience: A user commented that after replacing the connecting rod, the engine rotated smoothly, unusual knocking stopped, and the mower operated evenly during regular cutting tasks.
