Maintenance
It is important to lubricate the flex eyes frequently for
the first three (3) months after installation to evacu
-
ate contaminants that may build up during break-in
period.
After break-in period, the flex eyes should be lubricat
-
ed regularly as part of vehicle maintenance schedule.
Regular cleaning with pressurized water is recom-
mended to maximize ease of operation and reliability.
Always lubricate afterwards to evacuate any moisture
Flex Connect Rebuild
The internal components of the Flex Connect are
sealed and designed for maintenance free long term
performance. These instructions are provided as a
reference for the steps required to swap springs. The
Flex Connect Performance Spring Kit is sold separate-
ly as part number 2100.
1. FLEX CONNECT DISASSEMBLY
These instructions are written with the assumption
the customer has the assembly wrenches included in
the Performance Spring Kit. If not, 2 crescent wrench-
es with jaw openings up to 1-1/2" can be used.
Hold the body of the Flex Connect across the flats
and loosen the Flex Connect body as shown in the
Figure.
Note: A 3/8" rachet can be inserted into the square
hole in the wrench if additional leverage is required.
Note: If using a vice, put the cap in the vice jaws and
use the provided wrench on the body to prevent the
vice from binding on the threads.
With the cap unthreaded, slide the shaft assembly
out of the body.
Tip the Flex Connect body up and the spring fol-
lowed by the washer will fall out of the body.
To remove the spring from the shaft, hold the shaft
across the flats next to the bronze bushing and
remove the nut.
Note: The wrench with the rounded opening is 1/2"
across the flats for the rod and the other is 9/16" for
the nut.
Slide the spring off of the shaft.
Note: The spring washer goes on the side of the
spring towards the cap.
2. FLEX CONNECT ASSEMBLY
Install the washer back into the body of the Flex
Connect followed by the spring of your choosing.
Install a matching spring onto the Flex Connect
shaft followed by the bronze bushing and nut
Torque the nut to 25 ft-lbs.
IMPORTANT: Always install matching springs into the
Flex Connect. Failure to do so will create different roll
stiffness depending on the direction of roll and yield
undesirable handling characteristics.
Apply grease to the bronze bushing if it was re-
moved during disassembly
Slide the Flex Connect shaft back into the housing
and slide the cap down the shaft until the threads
engage.
Tighten the cap to approximately 25 ft-lbs.
