953C TIER II TTL WITH REPITCH TRACK AND TOUGH STEELTM SEGMENTS
New 953C Tier II Track Type Loaders (Serial No. BBX) being shipped from the factory (started August 2003) with new undercarriage, with hybrid links with increased track pitch and Tough Steel? segments. The track pitch increased from 6.91? (175.5mm) to 7.50? (190.5mm). The repitched sprocket segments changed from (3) four tooth and (3) five tooth per side (27 teeth total) to (5) five tooth segments per side (25 teeth total). The new undercarriage provides robust hybrid track links with slightly increased pin retention. The link assembly/shoe bolt pattern changed, and is now common with the D5H S&L link assembly. The bushings are slightly larger in outer diameter. The Tough Steel segments provide increased wear life for both the segments and the bushings. With the combination of the new repitch track and tough steel segments, can result in lower owning and operating (O&O) cost of the machine.
