2.2.3 Identifying A Good Splice
Often not enough emphasis is placed on the proper selection and installation of belt
laces. Unfortunately, if improperly installed, the result can be devastating — shortened
splice life, added costs, and increased down-time; just to mention a few. Listed below
are suggestions, which if followed, will increase your splice longevity.
What to look for:
1. Skive rough top back approximately one inch. Use
proper size lacing based on skived belt thickness and
pulley diameter. The correct lacing is provided with
the distributor belt assembly.
2. Hook is properly sized and clinched when: (Fig. 2-7a)
A. Hook legs are parallel. Loop should not have a
light bulb shape.
B. Hook points slightly penetrate opposite side of belt
(.005 to .015 inches).
C. 1/3 - 1/2 of the wire diameter is embedded into the
belt.
D. The “Knuckles” of the hook should not be higher
than the legs when installed.
3. Leave 1/4 inch on each edge of belt unlaced. This
guards against end hooks being pulled out.
4. Use one more hook on leading edge than on trailing
edge (Fig. 2-7b).
5. Chamfer the trailing edge. (QubicaAMF’s new
grooved belts are already chamfered.)
6. Laces should be uniformly embedded across the
entire width of the splice.
7. Edges of the belt should line up when the laced belt
ends are connected.
8. Run fingernail across loops of splice. Loops should
not move.
9. It is not necessary to bend the new notched
stainless steel pins, but they can be bent at the
ends to form a ‘J’ if desired (Fig. 2-7c).
