Holder C-Trac

Additional Notes

• The Holder C-Trac 2.34, 2.42, and 3.42 variants all share an identical combined transmission, hydrostatic, and hydraulic system capacity of 16.5 liters, indicating a unified fluid circuit across those three configurations.
• The C-Trac C 4.74 and C 4.80 models introduced from 2010 onward carry substantially larger system capacities, with the 4.74 ranging from 42 to 58 liters and the 4.80 ranging from 40 to 56 liters. A capacity expressed as a range rather than a fixed value typically reflects variation depending on system state, such as whether ancillary components are drained during service.
• The 2.34, 2.42, and 3.42 variants share a fluid check interval of every 150 operating hours under normal use conditions, paired with a change interval of 1,000 hours or 12 months, whichever comes first.
• The C 4.74 and C 4.80 models carry a check interval of 125 operating hours under normal use conditions, which is shorter than the 150-hour check interval specified for the earlier three variants.
• Under normal use conditions, the C 4.74 and C 4.80 models have a fluid change interval of 1,500 operating hours, which is 500 hours longer than the 1,000-hour change interval assigned to the 2.34, 2.42, and 3.42 variants.
• The C 4.74 and C 4.80 models each carry a separate first-change-only specification, requiring a fluid change at 500 operating hours. A first-change interval of this kind is typically associated with break-in wear particles accumulating in a new or rebuilt system before the standard service schedule takes over.
• The 12-month time limit on fluid changes applies only to the 2.34, 2.42, and 3.42 variants. The C 4.74 and C 4.80 specifications express change intervals in operating hours alone, with no calendar-based limit listed.
