CONTROL GP-BUCKET 1V9262 - Caterpillar

Fuel ratio controls are awkward to hold during disassembly and assembly. The new FT1820 (Change No. 1) Assembly Fixture is an inexpensive device that can be used to hold the fuel ratio controls. The new FT1820 (Change No. 1) Assembly Fixture is a redesigned (simplified) combination of the former FT1820 (Change No. 0) and FT1821 Fixtures. Dealers in the U.S.A. and Caterpillar Americas can order drawings of Fabricated Tools (FT) from the address that follows.
