DRESSTA TD-25M EXTRA
BULLGRADER „C“ FRAME
13. INSTALLATION
1. Drive the machine between the “C” frame (1, Fig. 17.9).
2. Position trunnion caps (4, Fig. 17.11) over the trunnions and connect them to the “C” frame (1)
with the bolts (5) and nuts. Be sure to tighten the bolts evenly. Determine the number of shims
(6) needed to fill the gap between caps (4) and the “C” frame (1), then add one additional shim
to provide clearance. Remove the bolts, add the number of shims (6) required. Reinstall the
bolts (5) and torque to 2100 [Nm].
3. Disconnect the lift cylinder hanger and wire from the main frame radiator guard and hydraulically
extend the cylinder rods until the eyes line up with the bracket on the “C” frame (4, Fig. 17.9).
Insert the mounting pins through the brackets, aligning the lock holes. Secure the pins with the
locking hardware.
4. Attach a hoist to the blade lifting eye and lower the blade (1, Fig.17.9) with lower struts (3) and
upper struts (2) or tilt cylinders (2A) into position. Align the pinhole in the swivel pin of “C” frame
(4) with the hole in blade bracket (1.17). Insert the blade center pin (1.4) through the bracket,
aligning the lock holes. Secure the center pin (1.4) with the mounting pin (1.5) and cotter pin.
5. Position the lower strut (3) in the “C” frame bracket. Insert the strut trunnion in the brackets on
the top of “C” frame and secure with the trunnion locking pin. Repeat this procedure on the
opposite side of the machine. Remove the blocks from the both lower struts (3).
6. Machine with hydraulic tilt: Reconnect the hoses (12, Fig. 17.10) to the right trunnion (26).
Reconnect frame to blade hoses (7 and 23) to the “C” frame plate (11). Install the hose guard
(20) to the “C” frame. Adjust and vent the blade tilt hydraulic system with “C” frame according to
OPERATOR’S MANUAL. Operate the tilt cylinders and check for leaks.
6. Install blade hoses connection cover (2, Fig.17.11) to the “C” frame (1) and secure with bolts (3).
Repeat this step on the opposite side of the machine.

14. REMOVAL AND DISASSEMBLY
WARNING! Before working at the machine, be sure that the blade and ripper
have been lowered to the ground, engine is OFF, the drive train neutral lock lever
is in locked (ON) position and parking brake is set. The starting switch and the
electrical system master switch are turned OFF, keys are removed and the
controls are tagged to prevent inadvertent engine starting.
CAUTION! Due to the considerable weight and bulk of each bullgrader
component, a suitable hoist or lifting device MUST be used. Remove each
component separately using suitable blocking on the remaining components.
