Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

WA, USA

 
 

Application Date:

1992

 
 

Application Situation:

Log loader bush housings.

 
 

Problem:

The bush housings were worn oversize.

 
 

Products:

Belzona 1111 (Super Metal)

Belzona 9411 (Release Agent)

 

Substrate:

Cast Steel

 
 

Application Method:

Application was carried out in accordance with Belzona Know-How System Leaft MPT-8. The housings were grit blasted. Belzona 9411 was brushed onto the new bushings. Belzona 1111 was applied to both surfaces and the bushings were twisted into place. A long shaft was inserted to align the four bushings.

 
 

Belzona Facts:

Welding and boring were considered but it would have stressed the metal, possibly causing misalignment of the arms. The cold applied Belzona product was the only true solution.
