3.0 GENERAL INFORMATION
3.1 Technical Description
The Camso TTS allows machines to move on muddy and soft soils which have limited
carrying capacity. The wide supporting surface of the track system also reduces soil
compaction.
Camso track systems are mounted on an axle frame. Certain equipment requires a
special axle to be installed prior to track system installation. Please contact your dealer
for more information.
Camso track systems are designed to maximize the performance and productivity of your
pull-behind applications with:
•Even weight distribution to easily and safely handle uneven terrain
•Excellent flotation to minimize soil disturbance (40 - 70% ground pressure reduction vs. tires)
•Maximum reliability to assure you get the job done anytime, anywhere

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 6
TTS uses Camso rubber tracks, specifically designed for pull-behind applications to
provide:
•Reduced vibration during transport
•Lower turning resistance
•Minimal soil disturbance
•Long life
The patented undercarriage design incorporates independent movement of the midrollers
both front-rear and side-side delivering:
•Even weight distribution, allowing tracks to follow ground contours
•A smooth ride over rough terrain
•Reduced point loads increasing longevity of the undercarriage and implement
components
Besides the above listed characteristics, Camso rubber track systems introduce other
advantages:
Reduced power absorption on soft soils
Minimal possibility of rubber track de-tracking from the undercarriage
Adequate roading speed
Limited soil damage, soil even during end of field maneuvers
Reduced risk of self-sinking in the mud in case of slipping
3.2 Track System Components

Frame
The main frame consists of a weldment which hangs the front and rear link arms. The
front alignment yoke and rear tension link are cast members, allowing for close tolerance
machining and structural rigidity.
Axles
Front and rear axles are machined from the yoke castings, allowing for dimensional
stability and few moving parts. They feature oil bath hubs mounted on tapered bearings
and mechanical seals for extreme working conditions. Each hub has its own oil reservoir
with access port for maintenance and checking oil levels.
Idlers and Midrollers
The idlers have the function of guiding the rubber track by acting on the lateral surfaces of
the guide lugs. Inner sides of idlers are subject to wear, but can be rotated to extend life.
The midrollers distribute the majority of the machine weight to the ground. They are
mounted on pivoting arms connected to the frame reducing vibration and shock loads.
Tensioning system
The tensioning system is located between the 2 rear idlers. The tension force is provided
by a mechanical spring mechanism. Track tension is provided by the spring and does not
need adjustment during operation and changing field conditions. Provisions are made to
compress the spring allowing for removal of idlers and track assemblies during
maintenance and servicing.
Rubber track
The rubber tracks are manufactured with high quality rubber and high strength steel
cabling inside for superior durability and reliability. The tread layout ensures good
flotation, excellent life, and self-cleaning characteristics.

WARNING
Exceeding maximum weight capacity may result in equipment and
property damage, injury, death and void warranty coverage
3.5 Transport Limitations
Camso track systems are designed for field use and field operational speeds. High speed
transport, especially with loaded implements, is not recommended and may result in track
damage due to heat. If extended transport is required between operating locations, the
following speed and duration limits should be observed:
Operating
Condition
Transport Speed
(Maximum)
Transport Duration
(Maximum)
Empty
15 mph (24 kph)
30 min.
Loaded
10 mph (16 kph)
15 min.
WARNING
Exceeding speed limitations may result in equipment and property
damage, injury, death and void warranty coverage.

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 9
If additional distances are required, a 30 minute cool down period is recommended before
transport is resumed. Absolute speed and duration levels may vary, depending on system
type and ambient conditions. Limitations as listed, help avoid system heat buildup that
could cause reduction in track life.
3.6 Minimum Turning Radius Limitations
Camso track systems operate best when running straight or in gentle turns. If a track
system is pivot or spot turned, the opportunity exists for soil and dirt to be ingested into
the system. Even though TTS has a tension recoil system, if that tension recoil is
exceeded, high loads in the frame and track can be generated which may cause track or
system damage, Camso recommends that minimum turning radius limits be strictly
observed, both in the field, and also on hard ground or pavement, to avoid high stresses
due to debris ingestion, potential untracking situations, high twisting and side loads, and
significant ground scrubbing of the track treads, especially if such a turn is attempted with
fully loaded or folded systems.

3.7 Operational Guidelines
Any application differing from the ones prescribed in this manual are to be considered
improper and potentially dangerous.
Correct track tension is required for best performance and track life.
Camso TTS can work in extreme conditions: for operator and machine safety, be sure
to know your surroundings.
Camso TTS is free to pivot around the main axle following ground contours. During
transition over uneven ground terrain, check for interferences and move slowly to
avoid over oscillating the undercarriage.
Overall width and height of machine/equipment with Camso TTS could differ from the
original width and height with tires. Be sure to know actual machine height and width
as well as width restrictions prior to operation.
Cross large ground irregularities with suitable speed reduction and/or proper incidence
angle. In particular, when high, sharp bumps are crossed move forward slowly to avoid
shocks on the machine.
Camso TTS does not damage standard road-bed constructions. Operators must know
and respect road traffic laws.
Rubber tracks have not been designed for extended use on the road. Camso is not
responsible for track and system damage resulting for extended road use. Long road
periods and/or roading at higher than recommended maximum speeds may cause
premature wear or failure of the track or wheels. To reduce damage during roading
decrease overall machine weight and decrease machine speed, see “Transport
Limitations” section for further information.
Long runs on side slopes increase the wear on the side of guide lugs and idlers.
Keep material out of the undercarriage. Inspect undercarriage daily and remove any
material as necessary. In some conditions inspect more frequently.
If a machine becomes stuck, clear away as much material from the undercarriage as
possible prior to pulling the machine out.
Avoid short turning radius turns and operation(s) especially when loaded. Spot turning
creates debris ingestion and can also induce high torque loading in the system.
Configure drawbar and hitch correctly during field operation(s).
Use caution when operating track systems in loose, flowing material. Loose material
can become trapped between track and idlers, resulting in track damage.
Keep material out of the undercarriage. This may require scraping material out of tight
places and in some conditions require frequent inspection and cleaning

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 11
3.8 Track Break-in Procedures
Guide lug wear is reduced when correct break-in procedures are followed. During the
break-in period, rolling components undergo a polishing-in process to achieve a smooth
steel to rubber interface with the guide lug. Rubber uses dust and dirt as a dry lubricant
during break-in and operation to minimize heat and reduce rubber stickiness. New tracks
should be exposed to dry and dusty soil conditions as soon as possible. Operation
without dust or soil in the system, especially during high speed roading, generates
high levels of damaging heat. If roading must be done, a dry lubricant such as soil, talc,
graphite, oil dry or cat litter should be applied to the guide lugs periodically during roading
until field operation resumes.
IMPORTANT: NEW SYSTEMS REQUIRING EXTENDED TRANSPORT
SHOULD BE CARRIED ON A FLAT BED AND NOT ROADED. DO NOT
ROAD A NEW SYSTEM WITHOUT FIRST CHECKING ALIGNMENT AND
INTRODUCING THE TRACKS TO DIRT OR DRY LUBRICANT
4.0 TRACK SYSTEM INSTALLATION
The Camso track systems are mounted on an axle frame. Certain equipment requires a
special axle to be installed prior to track system installation. Contact your dealer for more
information and to determine if the track system can be installed on your implement.
4.1 Handling of the Track System
The track systems can be handled by fork lifts lifting the machine from the base or by
hoists using textile bands.
WARNING
Danger of crushing. Use suitable lifting devices (capacity at least 9000 lbs
(4100Kg)), wear safety equipment and observe the safety rules.
If using a fork lift use for handling operations, be careful not to damage the
rubber track. Metal chains or cables are not recommended
4.2 Track System Installation
1. Clean the implement thoroughly before proceeding with the installation. Removal
of dirt and debris makes access to the frame and attaching fasteners easier.
2. Move the implement to a hard, level surface to ensure a stable work area to
support the implement during the track system installation.

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 12
IMPORTANT: Locate the identification tags, as shown above, on both undercarriages,
and record the model number and serial numbers on warranty certificate for your records.
3. Raise and support implement such that the rear tires are just off the ground.
IMPORTANT
Safety of the installation depends on the right operation in lifting
and supporting the machine. Check the work area thoroughly and
work in a level area. Respect safe operating practices, operate in
conditions of enough light. Make sure the free spaces of the work
area are suitable for the dimensions of the parts to be handled and
for the lifting equipment maneuvers. Be careful: risk of injury.
4. Remove the tire and rim assemblies.
5. Remove the axle and hub assemblies from the implement frame (as required).
6. Install track fitment axle. For two axle midroller track systems, make sure the
stabilizer brackets on the axle are facing to the front of the implement. Tighten
mounting hardware.
WARNING
Danger of crushing. Use suitable lifting devices (capacity at least
9000 lbs (4100Kg)), wear safety equipment and observe the safety

5.0 SCHEDULED MAINTENANCE
5.1 General information
Three factors: proper use, regular inspections, and maintenance are essential to ensure proper
performance and reliability of your Camso TTS track system.
It is strongly suggested to respect the recommended maintenance and inspection schedule in this
section for best track system life, proper performance, and reduced downtime.
Before any operation, clean all debris and material from the track system and make a general
analysis of the machine condition. Pay attention to components subject to wear such as rubber
parts: the quick identification of unusual wear, particularly of the track. Identifying and resolving
issues early reduces downtime and operating costs.
IMPORTANT
Routine and extra maintenance must be performed by qualified and
authorized personnel.
Before starting any kind of operation on the machine, disconnect the
transmission, stop the engine, set on the emergency brake, remove
the key and allow machine to stop completely and cool.
Make sure that mobile parts with safe fixed positioning are locked and
the tools used for maintenance are suitable for the type of service

1. Drain and replace idler, midroller, and midroller pivot reservoirs.
2. Oil level should reach to lower level of fill plug with unit parked on level surface.
5.9 Off Season Storage
1. For optimum life, TTS tracks should be stored indoors, in dry environment with
a temperature between 5° and 25° C (40-77F). The tracks should not be
exposed to direct sunlight or heat. No petrochemicals and related vapors, no
electrical devices producing ozone should be placed in the same area.
2. Should it be necessary to disassemble the tracks from the undercarriage, lay
them on the ground on one edge avoiding bending radius less than 30 in.(750
mm). Do not lay the rubber components on dirty surfaces contaminated by oil,
grease or other chemical products

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 19
3. Do not paint rubber components.
6.0 ROUTINE MAINTENANCE
6.1 Check Track Alignment
1. Install the stabilizer bars/turnbuckle assemblies to a “no” pre-load condition.
Turnbuckle jamb nut torque is 670 Nm +/- 65 Nm.Some play should be present
at the rod ends. Make sure to unscrew the lock nut on the turnbuckle prior to
adjusting the bars to the needed length.
2. Once installed, measure the inside distance front and rear on the mainframes
as noted below. Undercarriages must be parallel to within 6mm (0.25 in.). A
suitable location for measurement is noted by arrows below the turnbuckle eyes
in the diagram below.
3. Prior to checking track alignment the implement should be empty and spring
tensioning mechanism with no pre-load.
4. Pull the implement on a flat surface for a suitable time frame, allowing the belts
to relax and move freely on the undercarriage rollers.
5. Drive in a straight line for roughly 200 ft and coast the tractor to a stop. Place
the tractor in PARK and apply the emergency brake. Do not apply braking
action during this process as sudden stops can affect track position during the
alignment process.

CPB-515 Operation and Maintenance Manual –TTS 45, 70, 80,100, 110 Series (10-2017) 20
6. Using a ¼” x 4” x 8” shim (A) slide between the front midroller and guide lugs
(B). Bridge guide lugs with the shim maintaining pressure on 2 lugs minimum.
7. If the shim fits freely between the lugs and midroller on both sides of the
undercarriage the alignment is correct. It the shim binds and does not fit
between the midrollers/guide lugs track adjustment is necessary.
6.2 Track Alignment Procedure
1. Remove the retainer lock plate cap screws (b) and lock plate (c) from the inboard &
outboard sides of the track needing adjustment.
2. Loosen cap screw (d) counterclockwise 1-1.5 turns on the side of the
undercarriage you want the track to move towards.
3. Tighten the special cap screw on the opposite side to specification. (Cap screw
torque is 300 N-m (221 ft-lb). Tighten cap screw loosened in step 2 to the same
specification. Note: A single full turn is the standard increment during
adjustment. Lessen this amount as final adjustment is approached.
4. Recheck track alignment and adjust until suitable clearance is obtained on both
sides of the guide lugs. Note: Lock plates are reversible for double the index
increments. If needed, increase torque on the special cap screw slightly
allowing advancement to a suitable lock plate position.
