Craftsman Lawn Mower Camshaft Replacement

OEM Craftsman Lawn Mower Camshaft Engine Parts

Your Craftsman lawn mower's camshaft controls the precise opening and closing of intake and exhaust valves—timing that makes or breaks engine performance. Worn camshaft lobes result in weak compression, hard starts, and loss of cutting power. Repair Clinic supplies genuine OEM Craftsman camshafts engineered to original specifications, ensuring your mower runs like new.

Camshaft failure is less common than carburetor issues, but when lobes wear or the shaft bends, engine performance degrades quickly. Identifying your Craftsman model is essential—each engine generation uses differently-profiled camshafts. Browse our Craftsman Lawn Mower parts by model to locate the correct camshaft.

• Worn cam lobes: Weak valve opening, low compression, reduced power output
• Bent camshaft: Valve float, misfires, erratic idle, stalling under load
• Cracked or chipped lobes: Metallic noise from valve train, sudden power loss
• Stretched timing chain or belt: Valve timing drift, hard starting, backfiring

Craftsman Lawn Mower Camshaft Replacement FAQs

Camshaft replacement is an intermediate repair requiring patience and attention to valve timing. Below we answer the most common questions from Craftsman mower owners tackling camshaft work or diagnosing valve train noise.

How do I know if my camshaft is worn versus just dirty?

Worn lobes feel flat or pitted when you inspect them closely—compare against a new OEM camshaft if possible. A dirty but healthy cam will have smooth, rounded lobes and normal shine. If your mower loses power gradually over weeks and a carburetor cleaning doesn't help, worn cam lobes are likely culprit.

What is the timing procedure for a Craftsman camshaft?

Timing marks appear on the camshaft gear and crankshaft gear; these must align during installation. Most Craftsman single-cylinder models use a simple mark-to-mark procedure—consult your engine manual for exact mark locations. Incorrect timing causes severe starting and performance problems and should not be guessed.

Do I need to replace the timing chain when changing the camshaft?

Inspect the timing chain or belt first—if it's stretched, cracked, or severely worn, replace it alongside the camshaft. A worn chain causes timing drift and can repeat the valve train stress that damaged your original cam. OEM Craftsman timing chains and camshafts work together for longest life.

Should I replace valve lifters when installing a new camshaft?

Yes, new cam lobes are harder and round than worn ones; reusing old, rounded lifters causes premature wear and noise. Genuine OEM Craftsman lifter sets matched to your camshaft and engine generation ensure smooth, quiet operation and prevent repeat failure.

Craftsman Lawn Mower Model Number: Where to Look

On Craftsman lawn mowers, look for the model number on a label attached to the frame near the blade deck, under the seat, or on the engine housing. Clean off grass and dirt first, then copy the complete number, including letters, periods, or dashes. Enter it in the model number search to pull up the parts matched to your unit. The model number identifies the entire mower, so it narrows the full catalog to parts designed for that specific machine, not just one repair category. Matching the number before you order helps account for changes between mower versions and gets you the correct fit without sorting through unrelated results.
