Products:
Belzona® 1311 (Ceramic R-Metal)
Problem: 12-years prior, the assembly was rebuilt with Belzona® 1111 (Super Metal) which needed refurbishment. Excess play in the spline made it difficult for precision movements.

Belzona Facts
Both the male spline and the female socket of the bull gear were blasted. Belzona® 9411 (Release Agent) was applied to the spline and Belzona® 1311 (Ceramic R-Metal) was applied to both, subse-quently mated, aligned and indexed. There is really no affordable alternative for this 35-year old bull gear. It would have to be custom fabricated, which is both time consuming and costly.
