Wacker Neuson Telehandlers, TH

Brake fluid capacity & service interval

Wacker Neuson Telehandlers, TH use brake fluid with a capacity range of 0,5 to 1 liter. Service intervals include a check every 10 hours. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Wacker Neuson TH522 and TL48 models equipped with either the Perkins 404D-22 or the Perkins 404F-22T engine share an identical brake fluid capacity of 1 liter for the hydraulic brake system, introduced from 2015.
  • The TH627 with serial range 418-02 0001 and onward, fitted with the Kohler KDI 2504 TCR engine, carries a hydraulic brake system capacity of 0.5 liter, which is half the volume specified for the TH522 and TL48 configurations.
  • A 1-liter capacity in a hydraulic brake system of this class represents a relatively modest reservoir volume, consistent with compact telehandler brake circuit sizing rather than a large-vehicle overhaul fill quantity.
  • Across all three configurations, the brake fluid check interval is set at 10 hours of normal use operation, reflecting the frequency typical of construction equipment operating in demanding duty cycles where fluid condition can change rapidly.
  • The 10-hour check interval applies under normal use conditions for both the 1-liter TH522/TL48 configurations and the 0.5-liter TH627 configuration, meaning the inspection frequency is consistent regardless of the differing reservoir capacities.
