List of replacement parts
It is recommendable that, in addition to friction and separate plates, relevant O-Ring are
replaced with new ones as well.
NOTE: Quantity for No.7 O-ring: 4 for BMV75 and 2 for BM75.
For BMV series, as the seal for the second speed selection passage, 2 more are in
use than for BM series.
If it falls in any of the following cases, without waiting for 1,000 operating hours, replace the
friction and separate plates altogether.
1) When the braking force becomes weaker than driving force of hydraulic motor. (Despite that
the brake is being actuated, hydraulic motor rotates when HST drive is engaged)
Checking procedure: While depressing the parking brake switch, open the throttle fully and
engage the reversible travel lever. If traveling starts, replace the plates.
2) When total thickness of friction and separate plate falls short of the value in the chart
below.
