Welte Skidders

Additional Notes

• Across all Welte Skidder configurations covered in the 2010-2014 model range, the Deutz TCD 2013 L04 2V engine is the common powerplant, appearing in every listed variant from the W110 through to the W230.
• The front differential carries an 18-liter fluid capacity on all listed models, a notably larger volume than the 8-liter capacity specified for the bogie axle differential, reflecting the greater size and load-bearing role of the front differential housing in wheeled skidder drivetrains.
• The bogie axle differential holds 8 liters across every model in the W110, W130/K/M/T (both 113 kW and 129 kW variants), W180, W210, and W230 configurations, indicating a uniform axle assembly specification for that component throughout the lineup.
• Under normal use conditions, both the bogie axle and front differential on all listed models share a 1000-hour change interval, a figure typical of heavy forestry equipment operating in sustained, predictable duty cycles.
• An initial service interval of 350 hours applies to both differential locations across all models, replacing the standard 1000-hour interval for the first fluid change. Initial service intervals exist to flush out metal particles and manufacturing residues that accumulate during the break-in period of new drivetrain components.
• The W130/K/M/T variant is listed at two distinct power outputs, 113 kW and 129 kW, yet both share identical differential fluid capacities and service intervals for both the bogie axle and front differential positions, indicating the power difference does not affect the differential servicing specifications.
• The 350-hour initial service interval represents a reduction of 650 hours compared to the normal 1000-hour interval, meaning the first fluid change arrives significantly earlier in the machine's service life than all subsequent changes.
