Express quality
All cylinder express repairs are performed to Caterpillar specification standards,
ensuring every customer receives a cylinder that is brought up to the very latest
specifications.
Quality assurance standards and systems have been designed for every step of the
process, ensuring each and every repair meets our customers’ expectations.
For non-Caterpillar equipment, this focus on quality helps us deliver the same premium
repair to the very highest standards.
Express honing
To the naked eye, a cylinder repair may look fine, but decades of Caterpillar experience
shared by dealers across the world, tells us that even the slightest imperfection
can severely reduce performance. This is why Finning has developed its honing service
to remove even the smallest of imperfections that could accelerate seal wear life,
reduce machine productivity, and lead to unplanned machine downtime.
Cylinder groups assembled at Cylinder Express can be honed to ensure you benefit
from longer seal life, less downtime and increased performance.

Express test, test, test
'75-85% of hydraulic system failures can be traced to contamination', Hydraulics
and Pneumatics, June 1998.
Testing is an essential part of the Cylinder Express service, which sets us apart
from other cylinder repair service providers. At Finning we recognise that failure
to find potential faults, ultimately leads to additional customer downtime and in
the worst scenario expensive machine damage.
This is why we perform an extensive pressure test on all cylinders before they leave
the facility. Using state of the art equipment, each reassembled cylinder component
is inspected then pressure tested and certified clean using 'live oil' particle
count measuring equipment.
Express contamination control
The Cylinder Express facility is part of its equipment repair centre, a facility
that prides itself on contamination control. With more than 75% of hydraulic problems
traced to contamination, our control procedures make all the difference.
