GEAR-CONVERTER SUN 2S7833 - Caterpillar

service information for 637D Tractor-Scrapers now comes in two Service Manuals.
All disassembly and assembly modules are in, "637D Wheel Tractor-Scraper Disassembly And Assembly," Form No. SENR2447.
The original Service Manual, Form No. SENR7280 has the specifications, the systems operation, the testing and adjusting, and the schematics modules.
Dealers must have both manuals. It is Caterpillar's recommendation that those dealers that have only the original Service Manual, Form No. SENR7280 order the items that follow to make the new disassembly and assembly manual, SENR2447.
