9) Fill the transmission cover and case with 8 ounces
(224g) of high temperature transmission grease
containing an extreme pressure additive. Part Number
210-0720 lubrication grease or Fisk Brothers GR-132
is an approved lubricant. FIGURE 15. If the Fisk
Brothers lubricant can not be readily sourced, an
acceptable alternative is a marine-grade wheel bearing
grease that contains an EP (denoting extreme
pressure) additive. Distribute the grease equally around
all gear teeth. Do not utilize standard lithium based
greases intended for common lubrication purposes.
These types of grease are not formulated to operate at
the higher operating temperatures encountered during
the hole digging process. Such greases also do not
contain an extreme pressure additive for use with
gears.
FIGURE 15
10) Reinstall the primary gear and pinion assembly.
Distribute the grease equally around all gear teeth.
Replace the old transmission gasket with a new gasket,
PN 240-0100. Align the transmission dowel pins when
reinstalling the cover. Reinstall the fasteners with the
hexagon nuts on the cover side of the transmission.
Torque all fasteners to 96 in lbs (12 N.m.) in an “X"
sequence.
11) Rotate the final driveshaft and check for excessive
noise and/or binding. If excessive noise and/or binding
is evident, disassemble the transmission and
investigate for probable causes. Reassemble and
retorque to the specified amount. Recheck for
excessive noise and/or binding.
12) Inspect the Hole Digger for loose, worn or
damaged parts. Replace any questionable part or
assembly with a genuine, approved replacement part.
Do not attempt any maintenance or repair work not
described in the Operator Manual. Have such work
performed at your dealer's servicing shop.
MAGURA® THROTTLE CONTROL MAINTENANCE
PROGRAM.
Applications: All 200 Series models.
The Magura twist grip throttle controls engine speed
during the actual hole digging process. It has proven to
be a rugged, dependable device that delivers
exceptional service life while requiring only minimal
maintenance. Every 8 hours of actual operation and
whenever the throttle cable is replaced, the following
maintenance program is to be followed:
1) Remove the plastic cover to properly inspect the
internal components. Any worn or damaged
component should be replaced with a factory approved
replacement part only. FIGURE 16.
2) Normal use will produce a wear pattern by the
braided inner cable into the idler pulley. Maximum
allowable groove depth wear created by the throttle
cable is 0.045 inch (1 mm). A wear depth in excess of
this limit will require the replacement of the idler pulley.
3) Inspect the braided inner cable on a regular basis for
excessive wear and fraying in the area in direct contact
with the idler pulley. Abnormal wear or fraying will
require the replacement of the throttle cable.
FIGURE 16
4) Inspect the barrel end of the braided inner cable for
proper retention on a regular basis. A properly retained
barrel end will have no relative movement between it
and the inner cable. Any relative movement will require
the replacement of the throttle cable. FIGURE 17.
