Interval Schedule lists the page number for the step-by-
step instructions required to accomplish the scheduled
maintenance procedure.
Maintenance Intervals
Use the service hour meter to determine servicing intervals.
Calendar intervals shown (daily, weekly, monthly, etc.) can be
used instead of service hour meter intervals if they provide
more convenient servicing schedules and approximate the
indicated service hour meter reading. Recommended service
should always be performed at the interval that occurs first.
Under extremely severe, dusty or wet operating conditions,
more frequent lubrication than is specified in the maintenance
intervals chart might be necessary.
Perform service on items at multiples of the original
requirement. For example, at every 100 service hours, also
service those items listed under every 50 service hours and
every 10 service hours or daily.

Information
A Description of the Machine
For carrying larger payloads, the RCT150A answers the call
with capacity to carry 15,000-pound (6,804 kg). Its 275 hp
engine provides more horsepower than other machines in its
class. Reliable Rexroth hydraulic pumps provide exceptional
service life and arebacked byRexroth’s global service network.
The RCT150A’s design offers unrestricted access to engine
and hydraulic components for ease of serviceability. 28-inch
wide rubber tracks yield ground pressure of just 4.0 psi when
loaded. Powerful, 2-speed track drives achieve travel speeds
of 4.1 mph in low and 6.8 mph in high.
The RCT150A is also built with the operator in mind. Its
spacious cabin features heat and A/C as well as an opening
front window that doubles as an escape path and a high-
backed, air-ride suspension seat that’s heated and has
adjustable arm rests. The machine’s propel is controlled
by a single joystick, for ease of operation and controlled
response. A color display panel keeps operator alert to
engine performance and machine vitals.
The RCT150A Crawler Truck comes with a dump bed with
removable sides or as a cab & chassis that can be out outfitted
to meet the customer’s needs. It can accept a broad range
of truck beds/bodies, or fitted with equipment to perform
specialized tasks, such as drill rigs, aerial lifts, cranes, etc.
Auxiliary hydraulics can easily be added to the engine’s pump
drive or in line with propel pumps.

Serial Number Location & Information
Always have a record of the model numbers and serial numbers for your machine to specify when ordering parts. Record
your machine model and serial numbers below for your personal records.
Serial number is located as shown.
Use the below table to record identification numbers and dealer information.
Serial Numbers Location
Whenever communicating with Rayco or your Rayco dealer, have your machine serial number handy, as it can help pinpoint
most exactly what information is needed in caring for your machine.
Breakdown of the serial number
For Example: RCT150A 001 07 19
RCT150A - Type of Rayco equipment you have
001 - Three digit for the number of produced
02 - Two digit month, 01 = Jan., 02 = Feb., etc...
14 - Two digit year, 14 = 2014, 15 = 2015, etc
It is attached to the machine at the location shown. For ready reference, record it in the boxes provided on the inside front
cover of this manual.
For reference on communication regarding the engine, record its model and serial numbers also in the boxes provided on
the inside front cover of this manual. See the Engine Operator Manual for assistance in locating the numbers on the engine.
