TUFF TORQ K215A TRANSAXLE
General
The Tuff Torq model K215A is a rugged and efficient
transaxle designed to be used together with the Sauer-
Sundstrand hydrostatic drive unit, BDU-21L-207.
The heavy-duty automotive style differential and high
ground clearance provide smooth operation over rough
terrain.
IMPORTANT: Cleanliness is a primary means of
assuring satisfactory life on new or repaired units.
Cleaning parts by using a solvent wash and air dry-
ing is usually adequate. As with any precision equip-
ment, all parts must be kept free of foreign materials
and chemicals.
• Protect all exposed sealing surfaces and open cavities
from damage and foreign material.
• Prior to removing and disassembling transaxle, the
tractor should be steam cleaned or blown with com-
pressed air before beginning any repairs.
• It is recommended that all seals be replaced before
transaxle is reassembled. Lightly lubricate all seals
with a clean petroleum jelly prior to assembly.
• After transaxle is removed from the tractor, remove all
external components such as the brake arm, brake
actuating pins, control arm, input pulley, and frame
mounting hardware before separating case halves.
