01 / FIND YOUR REFERENCE

Choose a reference edition

Start with the model configuration, then choose a publication and explore its documented equipment.

Catalogue reference

Selecting equipment records your research choice. It does not calculate dimensions, establish an available combination or rate a truck.

About this edition & its evidence

T660/07 · ©2007. 2007 cab and sleeper catalogue. Interior legroom and sleeper lengths are not exterior BBC or body-width measurements. Later PACCAR engine ratings are kept in a separate edition.

Planning to transport the truck?

Measure fixed exterior width and mirror width separately, plus overall length, the highest accessory, fifth-wheel height and actual transport weight. Interior bunk width is not exterior width.

03 / UNDER THE SKIN

Powertrain & chassis

Verify the original chassis order and subsequent alterations. Read engine, gearbox and axle ratings together.

Numerical powertrain ratings need a dated configuration-specific source. PACCAR MX-13

Documented transmissions

Read the installed unit’s identification plate and build record.

2007 cab and sleeper catalogue. Interior legroom and sleeper lengths are not exterior BBC or body-width measurements. Later PACCAR engine ratings are kept in a separate edition.

04 / MODELS, YEARS & CHANGES

One badge.
Different reference points.

Publication dates and launch milestones do not establish continuous model-year ranges. Match the VIN, production date and equipment era.

Inspection and build evidence

Confirm emissions year and installed engine before comparing ratings. Inspect DPF access, hood and lamp repairs, sleeper seals, fairings and electrical service history.

  • VIN-linked factory build record and production date
  • Engine and transmission identification plates
  • Axle ratings, tyre ratings and fifth-wheel installation
  • Physical measurements of the individual tractor

05 / PUTTING IT TO WORK

Match the trailer to the whole truck.

Use the actual axle ratings, tyres, fifth wheel and combination limits to assess a trailer. Sleeper, tank and fairing packaging also affect swing clearance and access.

HIGHWAYTRAILERS.CA

Flatbed

Start with deck length, load placement, axle distribution and cab-to-trailer clearance.

Read the guide HIGHWAYTRAILERS.CA

Step deck

Compare deck height, gooseneck geometry and the loaded combination’s height.

Read the guide HIGHWAYTRAILERS.CA

RGN / equipment hauling

Check neck compatibility, fifth-wheel loading, wet-kit requirements and the complete axle layout.

Read the guide HIGHWAYTRAILERS.CA

How trailer capacity works

Review the tractor, coupling, trailer, tyres and load as one combination.

Read the guide

Pulling a trailer

Confirm build-specific combination, axle, tyre and coupling ratings, kingpin and service connections, clearance and actual axle weights. GVW is the loaded truck; GCW is the loaded combination. Neither is trailer payload.

Moving the tractor as cargo

Give the carrier measured length, exterior and mirror widths, height, ground clearance and transport weight. Assess deck access, breakover, loaded height and securement together.

Deck height & loaded height ↗
There is no single “T660 towing capacity”.

The model badge, artwork and catalogue option selectors cannot rate an individual combination. Obtain the actual build limits and scale weights.

Reference-specific evidence needed

  • A dimensioned T660 factory drawing is still needed; no BBC value is borrowed from the T600 or another Kenworth.
  • Exterior body width, mirror width, overall length, accessory height and coupling height need build-specific evidence.
  • A publication date does not establish every production-year boundary. Confirm the VIN and original order.
  • No dated factory exterior paint palette has been verified; the colour selector changes the illustration only.
