McCulloch TIMBER BEAR 13-600041-34 gas chainsaw Parts

We don’t use a single, fixed CC value for the Mcculloch TIMBER gas chainsaw because “TIMBER” is a model identifier used across different TIMBER Bear variants and engine configurations. To get the correct displacement (cc) for your exact saw, match the full model and engine markings, then use that information to select the right parts on Sears PartsDirect.

How to identify the correct cc on your saw

Use these quick checks on the Mcculloch TIMBER chainsaw before you assume an engine size:

• Confirm the complete model tag information (often more than just “TIMBER”).
• Check the engine housing for any stamped or printed displacement marking (for example, “cc” or “cm³”).
• Note the bar length and chain pitch currently installed; these often correlate with engine class.
• Compare the carburetor and air filter cover style to common Mcculloch layouts.
• If the cylinder has been replaced, treat the saw as “unknown cc” until you verify the top-end parts.

Typical cc ranges for gas chainsaws (what to expect)

Most consumer gas chainsaws fall into these displacement ranges; this helps you sanity-check what you find on the tag:

Chainsaw class	Typical displacement	Typical use
Light-duty	30 to 40 cc	Limbing, small trees
Mid-range	40 to 55 cc	Firewood, general cutting
Heavy-duty	55 to 70+ cc	Larger hardwood, frequent use

Why the “87 cc” info you may see online can be misleading

You may run into references to 87 cc Mcculloch engines (often tied to specific older engine families and custom builds). That number is not a reliable spec to apply to every “TIMBER” labeled saw. For parts accuracy, we match by model identification and component fit (carburetor, ignition, cylinder, crankshaft bearings), not by a guessed cc.

Why it matters

Correct cc identification prevents mismatched parts like the wrong carburetor, fuel line, air filter, or ignition module. On a gas chainsaw, even small differences in engine family can change mounting patterns and fuel system routing.

Mcculloch chainsaws are still around as a consumer outdoor power equipment brand; the original Mcculloch company changed hands over time, and the Mcculloch name continued under new ownership. For parts and model identification on your Mcculloch gas chainsaw model TIMBER, we focus on matching the exact model number to the correct parts list.

What this means for parts and repairs

Even when a brand changes ownership, the most important thing for repair success is using the correct model number and the correct parts diagram for that exact saw.

• Confirm the model number on the saw’s ID tag (not just the marketing name “TIMBER Bear”).
• Use the model number to match the right illustrated parts breakdown.
• Compare your existing part’s shape, mounting points, and measurements before ordering.
• Replace common wear items together when needed (chain, guide bar, sprocket, air filter).
• Use the correct 2-cycle fuel mix and bar-and-chain oil to prevent repeat failures.

Common reasons people think Mcculloch “disappeared”

Mcculloch products have been sold under different corporate ownership and distribution over the years, so availability and branding can look different depending on where and when the saw was purchased.

What you notice	What it usually means	What to do next
Model name is familiar but parts look different	Multiple versions existed across years	Match by model number and diagrams
Local stores do not stock parts	Parts are often special-order	Order by model number online
Saw is hard to start or won’t idle	Typical 2-cycle fuel or carburetion issue	Check fuel, filter, spark plug, carb settings

Why it matters

Chainsaws are model-specific: small differences in the carburetor, ignition module, clutch, or chain brake parts can prevent fit or create unsafe operation. Matching parts to TIMBER is the fastest way to get the right repair the first time.

Ordering help

For the Mcculloch TIMBER gas chainsaw, the correct chain size is the one that matches your bar length plus the bar’s pitch, gauge, and drive-link count. A very common setup for TIMBER Bear style saws is a 20-inch bar using 3/8-inch pitch, .050-inch gauge, and 70 drive links; confirm these specs on your guide bar before ordering from Sears PartsDirect.

How to confirm the exact chain size on your saw

Check the markings stamped on the guide bar (or printed on the bar label). We match the chain to the bar, not just the model name.

• Bar length (commonly 18 to 20 inches on many homeowner saws)
• Pitch (often 3/8 inch)
• Gauge (often .050 inch)
• Drive links (must match exactly; commonly 70 DL on some 20-inch setups)
• Chain type (full chisel vs semi chisel; choose based on cutting conditions)

Quick spec guide (what each number means)

Spec	What it controls	What must match
Pitch	Sprocket and bar groove spacing	Pitch must match bar and drive sprocket
Gauge	Thickness of the drive links	Must match the bar groove width
Drive links	Chain length	Must match the bar exactly
Bar length	Cutting reach	Chain must be sized for that bar

Why it matters

Using the wrong pitch, gauge, or drive-link count can cause poor oiling, derailment, binding in the bar groove, or damage to the bar and sprocket. Matching the bar specs keeps cutting smooth and helps the chain brake and tensioner work correctly.

Ordering tip for Mcculloch TIMBER

When you shop, search by the bar specs you confirmed (pitch, gauge, drive links) and keep your model number TIMBER handy to cross-check fitment.
