Menzi Muck Wheeled excavators

Transfer case fluid capacity & service interval

Menzi Muck wheeled excavators require 2,8 liters of transfer case fluid. Service intervals include checks at 8 months or 500 hours and 500 hours, along with fluid changes at 12 months or 1000 hours, 1000 hours or 12 months, and 100 hours. The data covers 4 configurations.

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

Additional Notes

  • The Menzi Muck Wheeled excavators A111E and A91E, both introduced from 2007, share an identical transferbox fluid capacity of 2.8 liters, indicating a service fill volume rather than a full overhaul drain-and-refill figure in most workshop contexts.
  • On the A111E and A91E under normal use conditions, the transferbox fluid check interval is set at 8 months or 500 hours, whichever comes first, pairing a calendar-based limit with an operational hours threshold.
  • The change interval for the A111E and A91E transferbox fluid under normal use is 12 months or 1000 hours, meaning the fluid is replaced at roughly double the frequency of the inspection cycle.
  • The A91F, introduced from 2011, carries the same 2.8-liter transferbox capacity as the earlier A111E and A91E configurations.
  • Under normal use on the A91F, the transferbox fluid check interval is defined solely by an hours-based threshold of 500 hours, without a calendar month equivalent listed alongside it, unlike the A111E and A91E specifications.
  • The A91F transferbox fluid change interval under normal use is expressed as 1000 hours or 12 months, with the hours value listed first, reversing the ordering convention seen in the A111E and A91E rows.
  • The A91F carries a separate initial service specification for the transferbox, requiring a fluid change at 100 hours, which is one-tenth of the standard 1000-hour change interval applied under normal ongoing use.
  • The 2.8-liter transferbox capacity on the A91F applies equally to both the initial service and normal use rows, confirming the fill volume remains constant regardless of service stage.
