1.)
Lay Moldboard on its face with ribbing up. To prevent paint damage place cardboard under top bend.
2.)
If assembling a 5' to 7' Moldboard skip to Step #3. If assembling a 7-1/2' or 8' Moldboard, locate four Mold-
board Spring Mount Brackets, two left (1TBP133L) and two right (1TBP133R). Refer to Figure 1.
Moldboard Spring Mount Brackets must be installed with Spring Mounting Tab pointing towards the outside of
Moldboard. Refer to Figure 3.
Mount each Moldboard Spring Mount Bracket using three 3/8"-16 x 1-1/4" Gr.8 Bolts (1TBP25), six Flat
Washers (supplied) and three Nylon Locknuts (1TBP36).
Torque all Bolts to 30 ft./lbs.
3.)
Assemble Trip Frame (1TBP22B) to Moldboard using four 1" x 4" Clevis Pins (1TBP23) and secure each with
a 3/16" Cotter Pin (1TBP24). Refer to Figure 4.
When installing Clevis Pins, work from Left to Right. Refer to Figure 4 for correct orientation of Clevis Pins
before installing. All Clevis Pins should be installed pointing towards the A-Frame. Tap with Hammer or Mallet
if needed to ease installation.
4.)
The F.E.L.B. has been designed with adjustable trip performance. Two Trip Spring mounting holes are
located on all three Trip Frame Spring Mounting Tabs, one Upper and one Lower. Refer to Figure 6.
The
Upper
Spring mounting holes will give a
lighter
trip when encountering an obstacle.
The
Lower
Spring mounting holes will give a
heavier
trip when encountering an obstacle.
4a
. Thread one 5/8"-11 Jam Nut (SN-MK1307) half way onto each of the four Spring Eyebolts (1TBP34).
4b
. Insert Trip Spring (1TBP33) end into hole on Spring Eyebolt, then insert each Spring Eyebolt into hole in
Moldboard Spring Mounting Bracket (orient Trip Springs as shown in Figure 5). Thread one 5/8" Nylon
Locknut (1TBP36) onto each of the Spring Eye Bolts.
4c
. Tighten the Nylon Locknuts until Trip Springs are taught.
Do not
overtighten Trip Springs when installing.
Fully tighten Jam Nuts.
4d.
Install supplied orange plastic End Caps to Spring Eyebolt ends to prevent corrosion.
5.)
Install Blade Markers (1TBP37) to Moldboard ends using supplied 5/16" Hardware. Refer to Figure 7.
