Assemble Blade Trip Springs
(29THD Series)
1. Open the carton and remove the blade parts bag
(part number 96114724).
2. Lay blade face down on floor, using cardboard or
similar material to prevent paint damage.
3. Install three 3/4" nuts onto the long threaded end of
the spring trip rod. (See Figure 1-11)
Figure 1-11
4. Install the long threaded end of the trip rod into the
saddle completely.
5. Tighten the closest 3/4" nut closest to the saddle.
6. Thread the two remaing 3/4" nuts down toward the
saddle as far as they will go (this puts minimum pressure
on the spring for following steps).
7. Install the 3/4” washer, spring cup, trip spring and
second spring cup on the free end of the trip rod.
8. Slide the trip rod assembly into a trip rod guide hole
in the blade. (See Figure 1-12)
Figure 1-12
9. Install the shock pad and shock plate onto the free
end of the trip rod.
10. Loosely install a 3/4" locknut on the free end of the
trip rod.
11. Apply a thin coating of grease to the main trip bolt
shank.
12. With an assistant and pry board or other suitable tool,
apply pressure to the lower part of the saddle until it
aligns with the mounting holes in the blade. (See Figure
1-13)
Figure 1-13
13. Install the greased 1" x 7" trip assembly bolt through
the blade and saddle.
14. Rotate the trip bolt to ensure that grease has covered
the inside surfaces of the saddle.
15. Install a 1" locknut on the trip bolt. Tighten the nut to
remove all freeplay from the bolt, but still allow it to spin in
the mounting holes and saddle. (See Figure 1-14)
Figure 1-14
16. Tighten the 3/4" nut against the washer and lower
spring cup until the distance between both spring cups is
14 inches.
