Clevis Hitch

Refer to Figure 7

The base hitch must be upright (with the recessed notch

on the bottom) for this conﬁguration. This places the

tongue weight on the base hitch, and not the clevis.

1. Select one each:

890-798C HITCH CLEVIS

802-487C HHCS 3/4-10X6 GR8

803-367C NUT HEX TOP LOCK 3/4-10 PLT

2. With the square-shouldered end of the clevis up,

fully seat the clevis in the upright base hitch .

Insert the Grade 8 bolt from below. Secure with

lock nut .

Hitch Failure Hazard:

Install the hitch base and assemble the clevis parts as shown.

Incorrect installation or assembly may result in failure of the

clevis bolt, leading to hitch failure. This could result in a seri-

ous highway accident or severe machine damage.

Category III Hitch

The base hitch must be inverted (with the recessed

notch on the top) for this conﬁguration. Set the

V-block to allow some vertical articulation of the draw

bar pin. Always use at least one cushion .

1. Select one each:

PPI-302V TOP PLATE - CAT 3

PPI-203VR V-BLOCK

802-383C HHCS 3/4-10X3 GR5

and two:

PPI-205H CUSHION

2. Set the cushions inside the hitch recess , just for-

ward of the vertical bolt hole. Position the V-block

forward of the cushions and check the size of the

resulting pinning hole. Remove a cushion if needed.

3. Add the top plate . Secure from below with

Grade 5 bolt .
