REBUILDS
Vancouver based United Gear & Machine Works Ltd. has been in business for over 50 years and
has been providing Western Canada with the highest quality gear box rebuild services for over 20
years. United Gear has risen above the competition through our commitment to quality and
continuous product improvement. When United Gear is selected as your transmission rebuild
partner you will:
All transmission rebuilds are the product of an in depth reverse engineering process which allows
the experienced staff at United Gear to identify the unique wear patterns and OEM weaknesses.
Working with mine management (to help understand the unique operational requirements) our staff
can identify and will collaborate on recommended improvements. With the focus on continual
improvement, we can provide the added confidence in extending component life, shorten rebuild
time, and improve operating costs.
EXPANDED HISTORY
MINING TRANSMISSION REBUILDS
In addition to the above shovel and drill transmissions, UG has also rebuilt 10 Lohmann &
Stolterfoht (L&S) Apron feeder transmissions. The significance of these rebuilds with respect
to mining shovel transmissions is that they are planetary transmissions, and L&S provides
planetary propel transmission for several brands of hydraulic shovels, so there should be a
very good opportunity on these rebuilds for the customers who have them. UG has also
rebuilt complete pump drives for a number of mining shovels, drills etc.
OUR PROCESS
TRANSMISSION REPAIR AND RETURN
IMPACT: These geometry improvements allow for an improved contact pattern and
operational load balance reducing wear and pitting.
CARRIERS:
• B-212124 1st Stage carrier is made from a custom forged material – normalized,
quenched and tempered. This material has a higher yield strength and superior wear
resistance versus the OEM cast material
• B-212132 2nd Stage carrier is made from a custom forged material – normalized,
quenched and tempered with a superior grain structure and yield strength compared
to the OEM cast carrier.
• Output bearing journal location has been tolerance increased +0.0010”-+ 0.0015 to
allow for closer tolerance fit to the bearing to help prevent bearing journal fretting from
normal operational deflections which occur from the thin wall carrier design.
CARRIERS:
• B-212241 2nd Stage carrier would be made using an improved forged alloy – normalized,
quenched and tempered. This material has a higher yield strength and superior wear
resistance versus the OEM casting material. We do not currently have a drawing
produced for this component, but have samples available. B-212251 3rd Stage carrier
would be made using an improved forged steel – normalized, quenched and
tempered. We do not currently have a drawing produced for this component, but have
samples available.
