D11R/N NEW AND IMPROVED MASTER LINKS
These new master links are used on D11R and D11N Track-Type Tractors from the factory and are available in the parts systems. The new geometry of this master link improves cracking resistance (larger radius - see arrows below) and increases service life. The former master links are canceled and replaced by the new master links and are interchangeable with former and new master links.
Adaptability
? The master link?s creative design can be used on all current D11R and non-current D11N machines in the field. The new master links are effective on the following D11R factory built machines.
