FAQ 

Q：Can belt with minor outer crack be used temporarily?
A：Tooth root is aging, crack spreads to cord quickly and sudden break may happen under load.

Q：Can standard non-tooth V-belt replace this toothed version?
A：Not recommended. Small pulley brings heavy bending stress, plain V-belt overheats and delaminates fast.

Q：Can slip be fixed simply by tightening tension?
A：Check pulley groove wear and oil contamination first, tension adjustment only works temporarily.

Q：Can oil-stained belt be reused after cleaning?
A：Oil penetrates rubber and reduces strength, replacement is required even after cleaning.
