Our Fluid Analysis reports display all machine and customer information, recommendations and sampling history in a concise, easy to understand format.


You can draw your fluid sample using la conventional vacuum pump, or a Toromont technician can install a sampling test port to any one of your machine's fluid compartments. When using a sampling test port you can easily draw fluid from your machine’s compartments using a probalizer tip included free in our 10-pack kits.

Oil Sampling Techniques



This sampling method requires a Brass Probe (8T9208) and approximately 15 cm (6 in) of tubing. If you are sampling several compartments, begin with the cleaner systems-usually the hydraulic system, then the transmission or steering system, and finally the engine system.

This sample method requires a Vacuum Pump (1U5718 or equivalent). Use this method for pressurized systems not equipped with sampling valves. Again, it is important to use a new piece of tubing after sampling engine oil because soot and oil additives may remain in the tubing and contaminate other samples.

Fluid analysis Toromont


The Toromont Fluid Analysis Team doesn't just focus on the condition of your oil, we also focus on the condition of your equipment.

S.O.S. fluids


We monitor your oil with methods developed by Caterpillar and designed to evaluate the condition of your machine components, not just the condition of your oil.

Coolant analysis


Cooling system problems contribute to more than 50% of all engine related failures. Diesel engines produce a tremendous amount of power and heat that must be dissipated to keep your engine running properly.

Diesel Fuel Analysis Program


It is an assessment of the general condition of the fuel. Poor fuel can cause poor combustion, premature fouling, corrosion, and problems with injectors.

S.O.S. Process


At Toromont Fluid Analysis we offer a service customized to your needs. Dealing with us is as easy as you'd like it to be.
