McCulloch MAC 4600 11-600465-07 chainsaw Parts

Engine size (cc) depends on the exact Mcculloch model and engine family, not just the “MAC” name. For your Mcculloch model MAC, we match the correct engine displacement by using the full model identification on the saw (often on the starter housing or crankcase) and then cross-referencing parts by model on Sears PartsDirect.

How to find the correct cc for your specific saw

Use these quick checks on the chainsaw itself; they identify the exact engine version tied to the cc rating:

• Look for the full model and type code on the ID label (not just “MAC”).
• Check the engine tag for a displacement marking (often shown as “cc” or “cm³”).
• Note the serial number range; some production runs use different engines.
• Confirm whether it is a 2-cycle gas saw (most Mcculloch MAC-SERIES saws are).
• Match what you find to the parts breakdown for the exact model identification.

Typical cc ranges (so you know what to expect)

Most homeowner gas chainsaws fall into a few common displacement bands. This helps you sanity-check what you find on the label.

Typical cc range	Common use	What you will notice
30 to 40 cc	Light trimming, small limbs	Lighter weight, shorter bars common
40 to 50 cc	General firewood, storm cleanup	Good balance of power and weight
50 to 60 cc	Heavier cutting, larger rounds	More torque, usually louder and heavier

Why it matters

The cc rating affects which carburetor settings, fuel line sizes, air filter style, and ignition components your saw uses. Matching parts by the exact model identification prevents hard-starting, rough running, and poor cutting performance.

If your saw is hard to start or runs rough

These issues often get mistaken for “wrong cc” when the real cause is fuel or ignition related:

• Drain old fuel and refill with fresh, properly mixed 2-cycle fuel.
• Check the spark plug condition and gap.
• Inspect fuel lines for cracking or air leaks.
• Clean the air filter and verify the choke is operating.

To identify your Mcculloch chainsaw model, we look for the model identification stamp or tag on the saw body. On many Mcculloch saws, the model is stamped into the crankcase area (often on the underside), and those stamped numbers are what you use to match the correct parts list for your saw.

Where to look for the model number

Check these common locations on Mcculloch chainsaws:

• Underside of the crankcase or engine housing (look for stamped characters)
• Near the starter housing or recoil cover
• Around the handle frame or rear handle area
• On a small ID plate or decal (if it has not worn off)

What to write down (so parts match correctly)

When you find the stamp or tag, record the details exactly as shown:

• Model number (letters and numbers)
• Type or series number (if shown)
• Product number or spec number (if shown)
• Any suffix after the model (for example, a dash and extra digits)

Quick check: what matters most

What you find	Why it matters
Model number	Gets you to the correct illustrated parts breakdown
Suffix/spec number	Separates similar saws that use different carburetors, fuel lines, or ignition parts
Serial number	Helps confirm production run when parts changed mid-series

Why it matters

Chainsaws that look identical can use different parts (carburetor settings, fuel line routing, bar and chain fit, ignition modules). Using the exact model identification prevents ordering the wrong components and saves time during troubleshooting.

If the tag is missing or unreadable

Use these practical checks to narrow it down:

• Compare your bar length and chain pitch/gauge to what the parts list expects
• Note whether it is a gas saw and whether it uses a primer bulb
• Inspect the carburetor and air filter style (common differentiators)
• Use our chainsaw DIY resources to match symptoms to likely systems (fuel, spark, compression)

For repair and identification help while you track down the correct model details, use the chainsaw category landing page. For ordering once you have the model information, search by the exact stamped model number on Sears PartsDirect.

Mcculloch chainsaws did not disappear; the Mcculloch name continued under new ownership after the original company changed hands. Today, “Mcculloch” is primarily a consumer outdoor power equipment brand, and parts support typically depends on the exact model identification and the current brand owner’s product line.

What this means for your Mcculloch MAC chainsaw

Even when a brand changes ownership, the biggest practical issue is parts identification. For the Mcculloch MAC chainsaw, match parts by the model and the specific component (carburetor, fuel lines, ignition, bar and chain, clutch, oiling system) rather than by brand history.

• Use the model number MAC when searching parts diagrams and listings
• Confirm the engine family and serial tag details before ordering
• Expect common wear items to be the first replacements (spark plug, air filter, fuel filter)
• Treat fuel system issues as the most common “won’t start” cause (old fuel, clogged carburetor, cracked fuel lines)
• Prioritize safety parts and adjustments (chain brake function, chain tension, bar condition)

Common parts that are still widely serviceable

Most consumer gas chainsaws remain serviceable because many components are standard across platforms.

System	Typical service items	Common symptom when failing
Fuel delivery	Fuel lines, fuel filter, carburetor	Hard starting, surging, stalls
Ignition	Spark plug, ignition module	No start, intermittent spark
Cutting system	Chain, guide bar, sprocket	Poor cutting, vibration
Oiling	Oil pickup, oil pump, oil line	Dry chain, smoking bar

Why it matters

Brand ownership changes can affect which exact parts are stocked under a given name, but your repair success still comes down to matching the correct part to the correct model and symptom. That prevents wrong orders and repeat failures.

Yes. Mcculloch chainsaws, including the Mcculloch MAC chainsaw, are built for solid homeowner-level cutting performance with a focus on usable power, manageable weight, and practical ergonomics. Overall quality depends most on routine maintenance (fuel system, chain condition, and bar lubrication) and correct setup for the job.

What “good quality” means for a chainsaw

Quality shows up in how consistently the saw starts, cuts, and holds adjustment over time. For most gas chainsaws, these are the biggest indicators:

• Starts reliably hot and cold (no excessive priming or repeated pulls)
• Idles smoothly and accelerates without bogging
• Oiler keeps the bar and chain properly lubricated
• Chain stays sharp and tensioned without frequent readjustment
• Anti-vibration and handle layout reduce fatigue during longer cuts

Maintenance that protects performance (and your parts budget)

Most “quality” complaints come from fuel, air, or cutting-attachment issues, not the engine itself. We recommend these habits:

• Use fresh, properly mixed fuel (and empty the tank for long storage)
• Clean or replace the air filter regularly
• Keep the chain sharp and set to the correct tension
• Confirm bar oil is flowing before cutting
• Inspect fuel lines and the fuel filter for cracking or leaks

Symptom	Most common cause	What to check first
Won’t start	Fuel delivery or spark	Fresh fuel mix, spark plug condition
Runs rough	Dirty carburetor or air restriction	Air filter, carburetor settings
Leaks gas	Cracked fuel line or loose connection	Fuel lines, tank grommet
Cuts slowly	Dull chain or wrong depth gauges	Chain sharpness, file guide use

Why it matters

A chainsaw can feel “low quality” if it is hard to start, runs rough, or won’t oil the bar. Fixing those basics restores cutting speed, reduces wear on the clutch and bar, and helps prevent overheating.

Mcculloch chainsaws have been around since the 1940s; the Mcculloch company began in 1943 and produced its first chainsaw shortly after that. For your Mcculloch model MAC (MAC 4600 11-600465-07), the exact age depends on the specific production year of your unit.

How to estimate the age of your Mcculloch MAC chainsaw

We use the same practical checks on most gas chainsaws to narrow down the build timeframe:

• Look for a data plate or sticker on the starter housing, rear handle, or near the fuel tank
• Write down any serial number, date code, or type/variant marking
• Compare your saw’s features (primer bulb style, choke lever layout, chain brake design) to parts diagrams and common configurations
• Check whether the saw uses older-style carburetor adjustment screws (often indicates an older design)
• Note any emissions labeling (later models often have more prominent compliance labels)

What “how old” usually means (quick reference)

Because the model number alone does not reliably encode the manufacturing year, we recommend using the identification markings on the saw.

What you have	What it tells you	What to do next
Serial number or date code	Often the most accurate age clue	Record it exactly, including letters
Only model number (MAC)	Identifies the model family, not the build date	Use physical labels and feature clues
No readable labels	Age estimate only	Compare visible components and layouts

Why it matters

Knowing the approximate age helps us match the right carburetor, fuel lines, ignition parts, and bar and chain setup, and it also guides maintenance decisions (fuel system cleaning, replacing brittle lines, and checking crank seals).
