Zetor Crystal

Additional Notes

• The Zetor Crystal front rigid axle differential holds 6 liters, which is 2 liters more than the 4-liter capacity specified for the front suspended axle differential across the Crystal 150 and Crystal 160 variants equipped with the Deutz TCD6.1 L6 engine.
• A first change only interval of 100 hours applies to the front rigid axle differential on the Crystal 150 and Crystal 160, meaning the fluid is drained and refilled at that early point before the standard 1000-hour change cycle takes over under normal use conditions.
• The same first change only interval of 100 hours applies to the front suspended axle differential on the Crystal 150, Crystal 160, Crystal HD 150, and Crystal HD 170, each with a 4-liter capacity at that initial service.
• Under normal use conditions, the front rigid axle differential on the Crystal 150 and Crystal 160 requires a fluid level check every 100 hours, with a full fluid change scheduled at 1000 hours.
• The front suspended axle differential across all four variants — Crystal 150, Crystal 160, Crystal HD 150, and Crystal HD 170 — shares an identical normal-use service schedule: a 100-hour check interval and a 1000-hour change interval, each with a 4-liter capacity.
• The Crystal HD 150 and Crystal HD 170 are specified only with a front suspended axle differential, carrying a 4-liter capacity, whereas the Crystal 150 and Crystal 160 include specifications for both rigid and suspended front axle differentials.
• The Crystal HD 150 and Crystal HD 170 share their front suspended axle differential capacity and service intervals exactly, with no variation between the two variants despite the difference in model designation.
