摘要

#CMT# #/CMT# The tool has a drive head (4) and a socket (3) for tightening a threaded fixing connecting a tube to a support. The socket has a slot for the tube, and the drive head and socket are coaxial and connected by an offset intermediate body (5) with a housing (54) containing the shaft (52) of a reduction gear mechanism (41, 51, 53) with a gear ratio of about 9 : 1. The drive head also contains a torque sensor (6). #CMT#USE : #/CMT# Tightening a tube fixing to a support, especially for an internal combustion engine fuel injector. #CMT#ADVANTAGE : #/CMT# The tool allows injectors to be installed quickly and easily, using only one tool. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a lengthwise section of the tool. 3 : Socket 4 : Drive head 5 : Intermediate body 6 : Torque sensor 41, 51, 53 : Reduction gear mechanism 52 : Shaft 54 : Housing.
