ENGINE DIAGNOSTIC TEST PROCEDURES
Section 6
Accelerator Linkage Identification
Two different types of linkages exist, (without Bellcrank)
and (with Bellcrank). These two types of linkages have
differnet versions as follows:
Without Bellcrank (Figures 2a and 2b)
•
Version "I" Linkage used with the RQV
standard regulation governor.
•
Version "II" Linkage used with the RQV
close regulation governor.
With Bellcrank (Figures 3a - 3c)
•
Versions "I" and "II" Linkage used with the
RQV standard regulation governor.
•
Version "III" Linkage used with the RQV
close regulation governor.
Visual identification of linkage used with standard
regulation and close regulation governors can be
accomplished by measuring control lever movement.
Refer to Figures 2a-2b and 3a-3c.
Standard Regulation Governor
The control lever will rotate about 45° from low to high
idle position and travel approximately 2.3 inches.
Close Regulation Governor
The control lever will rotate about 33° from low to high
idle position and travel approximately 1.7 inches.
