The Mysterious Husqvarna 170 CD Chainsaw

| | ,

The Husqvarna 170 CD is a very early version of the Husqvarna 162 SE.

There are very few discussions of the model online, with the best one being here on chainsawcollectors.se (over 5 forum pages). This is a summary of that thread on, sharing what the members concluded about the model.

The featured image comes from user ‘Frits’ who managed to get his hands on a 170 CD!

What the chainsawcollectors.se thread concludes (high confidence):

  • A Husqvarna “170CD” is essentially a 162-series saw wearing a weird/rare ID tag: the examples shown have a 170CD case tag but a 162SE recoil decal.
  • Multiple experienced collectors/admins in the thread (esp. Magnus) converge on: prototype / pre-series / test-run saw, not a normal marketed production model.
  • A major supporting clue in the thread is the absence of a KAS number (explained there as Swedish work-safety testing/approval). The implication: not approved for sale in Sweden, therefore unlikely to be standard production.

Known sightings / serials discussed

  • USA example (initial post): photos shared, but no hard measurements were obtained in-thread beyond visual comparisons.
  • Spain example (later found online, then acquired by Frits): serial clarified as 1000047 (initially misread as 1000347). Frits later states they now “know for sure” it’s effectively “the very first 162,” and mentions “3 162 with a 170 tag.”

Physical differences and “early-run” tells noted in the thread (these are the practical, saw-in-hand differences people kept coming back to):

  • Small air filter + matching top cover:
    • The 170CD cover “only fits with this small airfilter,” and the cover has no Husqvarna badge.
    • Magnus notes early 162s also used the smaller filter (and suggests early 266 may have, too).
  • Crankcase differences: explicitly called out (“Crankcase is different”).
  • Starter mounting pattern:
    • Frits: 3-bolt starter on the 170CD vs 4 on a 162; then confirms no threaded hole at all for a 4th bolt.
    • Magnus replies that early 162s also had a 3-bolt starter, and even references a museum example.
  • Measured / identified components (hard data finally arrives in 2023):
    • Bore: 48 mm (posted by Frits, with photo evidence in-thread).
    • Carburetor: Tillotson HS163A (posted by Frits, with photo evidence in-thread).

Why “170CD” became “162” (theories in the thread). Two compatible ideas are floated:

  • Pre-series naming / internal project labeling: “100 series” style numbering + CD on the plate as a pre-production identifier.
  • Marketing rename to match displacement conventions: a long-time Husqvarna dealer in the thread speculates it was originally destined to be “170,” but was renamed 162 before broad release, aligning better with ~62cc.

Specifications

Because the thread consensus is “170CD = earliest 162-family,” the best way to present specs is:

  • Confirmed on 170CD examples (from the thread’s photos/measurements)
  • Published 162/162SE specs (used as the reference baseline)
Spec / attribute170CD (confirmed in thread)162 / 162SE published spec baseline

Production timing (best available)Thread belief: pre-series / test run; “earlier than 162” or “first 162” depending on poster162 described by Husqvarna as launched in 1975 (Sweden/Finland). Third-party summaries list 162SE as 1975–1977 and other parts sources show documents through ~1980
Heated handles variantNot stated for 170CD162 SG variant noted (heated handles)

From the thread’s hard evidence: the 170 CD a 162-family saw with a 170 CD ID plate, 48 mm bore, Tillotson HS163A carb, small-filter/top-cover combo, and early 3-bolt starter pattern — plus at least one documented serial (1000047).

If anyone wants to lock this down even further (what the thread still wants), the remaining “would settle it” items were:

  • Casting date codes (“casting clocks”) on case/cylinder/crank parts
  • Cylinder markings
  • Stroke measurement (to remove any remaining doubt about displacement)

However, at the very end of the thread, Frits shared the following image of a Husqvarna 162 from the Husqvarna museum, where they have a saw that’s tagged 170 CD.

Translation (Swedish → English):

“Motorsåg, modell 162 SE” → “Chainsaw, model 162 SE”

“64,6 cc, 4,2 hk” → “64.6 cc, 4.2 hp” (hk = hästkrafter, metric horsepower)

“Tillverkades åren 1975- (272XP)” → “Manufactured during the years 1975– … (272XP)”

The dash after 1975 implies “from 1975 onward” (the end year isn’t shown here).

The “(272XP)” in parentheses reads like a lineage/related-model note (e.g., “this sits in the line that later leads to / relates to the 272XP”), not part of the production date.

“Tillv.nr. 1000070” → “Manufacturing no. 1000070” (or “production no.”)

This is basically the smoking gun for the thread’s conclusion: the museum publicly labels the exhibit as 162 SE, but the saw itself is wearing the same 170CD-style ID plate. That’s exactly what you’d expect if “170CD” was an early internal/pre-series designation that later became the marketed 162 / 162SE name.

The manufacturing number 1000070 is very close to the other early number discussed in the thread (1000047), which supports the idea of a tiny early batch / pre-production run.

One interesting wrinkle: the sign’s 64.6 cc doesn’t match the commonly cited 48 mm bore + 34 mm stroke = ~61.5 cc, and it also conflicts with the thread’s later “48 mm bore” measurement on the 170CD example.

A few plausible explanations:

  • Museum placard typo (digits swapped / wrong source).
  • Different early cylinder spec on some earliest units (less likely, but possible).
  • Loose rounding / inconsistent reference data used for the exhibit text.
  • The 4.2 hk figure does line up nicely with the usual published power (~3.0 kW), because 4.2 hk ≈ 3.09 kW.

Net: the photo is strong evidence that at least some “170CD-tagged” saws are the earliest 162-family saws, and the museum chose to present the public model name (162 SE) while keeping the original early ID tag on the artifact.
