Overview

Packaged as a matched set, this 12” guide bar and chain combo delivers factory-level cutting performance as an aftermarket replacement. When either the bar or chain shows significant wear, the best practice is to replace both simultaneously. This combo simplifies the process and guarantees proper fitment between the two components.

Key specifications

  • 12” guide bar and chain combo
  • Chain pitch: 1/4
  • 64 drive links
  • Matched bar and chain for optimal tracking
  • Low-kickback design for safer operation

Compatibility

This combo set is designed for various manufacturers chainsaws as listed above. Verify bar length, pitch, gauge, and drive link count match your saw’s requirements before purchasing.

Installation notes

Disconnect power or remove the spark plug wire before working on the cutting assembly. Fit the new bar onto the mounting studs, wrap the chain around the nose sprocket and drive sprocket, and tension according to the owner’s manual. Always check chain direction: cutters on the top should face away from the body of the saw.

Common questions

Q: Will this 12-inch guide bar 3670 005 0064 fit my chainsaw, or is it only compatible with certain models?

This guide bar is only compatible with specific chainsaw models, so you’ll want to match the bar number 3670 005 0064 and confirm fitment against the listing before installing it. The safest check is to compare your current bar’s mount pattern, bar length, chain pitch, and gauge to your original setup.

Q: Can I reuse my old chain with this 12-inch replacement guide bar, or do I need a matching new chain?

You can only reuse the old chain if it matches the new bar’s exact specifications for length, pitch, and gauge and is still in good condition. If the old chain is stretched, worn, or doesn’t sit properly in the bar groove, replace it with the correct matching chain to avoid poor cutting performance and premature bar wear.

Q: What should I do during installation and maintenance to keep this chainsaw blade and guide bar working properly?

When installing the bar, make sure the chain tension is snug but still allows the chain to move freely by hand, and verify the chain is facing the correct cutting direction. For maintenance, keep the bar groove clean, check that the oiling hole is not blocked, and periodically inspect the rails for uneven wear so the bar and chain last longer.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
