How to confirm the fit

  1. Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g. 3/8" LP .050".
  2. Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
  3. Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ

What size chain does a McCulloch POWERMAC 1600 take?

How do I know which gauge my POWERMAC 1600 chain is?

Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the POWERMAC 1600 are .050" / 1.3mm.

Can I put a longer bar on my McCulloch POWERMAC 1600?

Oregon lists 35cm bars for the POWERMAC 1600. Stay within this range — a longer bar than the engine is rated for cuts slowly and accelerates wear.
