Used Caterpillar industrial & commercial machinery in Islamabad & Rawalpindi
Is a used Caterpillar industrial & commercial machinery worth buying?
Caterpillar reaches Pakistan as used imports, and the pool straddles a real divide. The mechanically governed engines, the 3306 and 3406 families, can be timed and set up by any competent diesel shop. The C-series that followed — C7, C9, C15 — is electronically controlled, and diagnosing one properly means someone with Caterpillar's own software in the room. That fact moves two otherwise similar machines in opposite directions.
Imported
Parts usually have to be imported or sourced from the grey market, so a repair takes longer and costs more — which matters more on an older unit than the build quality does.
Nothing on a CAT is made in Pakistan, so genuine parts come through the authorised dealer network or the used-parts trade, and lead time is part of every repair decision. Filters and routine service items circulate freely; electronic injectors, ECMs and major components are what keep a machine standing.
Checking a used Caterpillar industrial & commercial machinery
These are specific to Caterpillar. The general industrial & commercial machinery checks apply too and are on the industrial & commercial machinery page.
Mechanical or electronic
A 3306 has a mechanical governor and injection pump that a local shop can time on the bench. A C7 or C9 uses hydraulically actuated electronic injectors, so low engine oil pressure or the wrong oil can present exactly like a fuel fault, and the diagnosis starts with software.
Ask for an ET read
On the electronic engines, Caterpillar Electronic Technician reports stored faults, total fuel burned and the ECM's hour count. A seller who lets it be read has handed you the machine's history; one who cannot leaves you with an hour meter and a guess.
Look for rebuild evidence
Caterpillar supports rebuilding with its own Reman components, which carry their own part numbers and tags, and rebuilt units are commonly re-tagged rather than left with the original plate alone. Tags, workshop invoices listing parts, and an arrangement that matches are what turn a claimed rebuild into a checkable one.
Ask for oil-sample history
Caterpillar dealers run a scheduled oil-sampling programme, so machines maintained through one leave a trend on paper: wear metals, coolant traces, soot. Reports across several intervals say far more about the bottom end than standing at the exhaust ever will.
What Caterpillar industrial & commercial machinery are worth
- The mechanical 3306 and 3406 engines hold value here for a practical reason: they can be diagnosed and set up without software, so any diesel shop is a possible repair rather than one specific workshop.
- The rebuild economy is real but only counts when it is documented — Reman tags, invoices and a matching arrangement carry value, while an undocumented 'freshly overhauled' carries none.
- Everything brand-specific is imported, so a fault needing a genuine component costs waiting as well as money, and used values here already sit around that.
- An electronic machine offered with no ET read available is valued cautiously, because faults and fuel history that would be visible in minutes are simply not on offer.

General industrial & commercial machinery checks
These apply whatever the badge on the front says — the industrial & commercial machinery page covers them in full.
Put a real load on it
An unloaded machine tells you little. On an air compressor, time it up to cut-out pressure, then stop it and watch the gauge: a receiver that bleeds down within minutes has leaking valves, unions or a worn non-return valve. On a driven machine, load the spindle or the feed and listen for the motor bogging down.
Check the floor, not the machine
Machines get wiped down before a viewing; the floor underneath does not. A dark patch under the sump, gearbox or hydraulic ram records a leak that has been running a long time. Fresh paint on a gearbox casing or a cylinder head usually hides the trace of that leak rather than a restoration.
Compare the hour meter with the wear
Hour meters are the odometer of this category and are swapped just as freely. Read it, then look at the controls: handwheel knurling worn smooth, polished slideways, pedals rubbed bare. Low hours on a machine with heavily worn controls means the meter has been changed or left disconnected, and the reading is worth nothing.
Wind the handwheels and feel the backlash
On a lathe or milling machine, turn each handwheel back and forth. The free movement before the slide actually travels is backlash in the leadscrew and nut, and a large amount means the machine can no longer hold a size. Check the bedways for scoring and for a worn dip near the chuck, which is where the work has been done.
Read the plate for supply and starter
The rating plate gives the kilowatts, the phase and the full-load current, which decides whether a site can run the machine at all. Ask whether the starter, contactors and overload relay are included, since a motor above a few kilowatts needs proper starting gear and a machine arriving without its panel is not ready to work.
Look inside the pressure vessel's drain
Open the drain valve at the bottom of an air receiver. Water should come out, because a tank drained regularly has some. A drain left shut for years means the vessel has been standing in its own condensate and corroding from the inside, which cannot be seen from outside and cannot be repaired.
