MAINTENANCE INFORMATION
Drive Belt alignment and tension are pre-set at the factory
and are not adjustable. They are critical for proper operation
of the drive system. Return the vehicle to a CENTAUR dealer
if rapid belt wear occurs.
7.2.2 CLUTCH MAINTENANCE
Disassembly and repair of the driver and driven clutch re-
quires special tools. Return the vehicle to a CENTAUR dealer
if the clutch units need servicing. The following indicates that
clutch service is required:
•
a drop in vehicle performance
•
the clutch does not shift smoothly
•
the clutch sticks during vehicle operation
•
the drive belt wears rapidly
•
the vehicle vibrates severely during operation
•
the vehicle does not accelerate when the engine speed is
increased with the transmission in gear
•
transmission will not shift smoothly into gear at engine
idle

Clutch Inspection
Lubrication of the clutch parts is not required. Do not lubri-
cate the driven clutch.
Inspect the plastic sliders every 50 hours. The plastic sliders
are mounted in the driven clutch moveable pulley. (Figure 7-
3). When the clutch shifts, the cam moves on the nylon sliders.
Replace the plastic sliders before there is aluminum to
aluminum contact between the cam and the movable pulley.
Driven clutch disassembly is required to replace the nylon
sliders properly. Return the vehicle to a CENTAUR dealer
for service.
7.2.3 DRIVE CHAINS
Roller chain “stretch” results from wear to the chain pins and
bushings because of the loss of lubricant.
To prevent sprocket damage and unnecessary breakdowns,
replace the chains when:
•
the chain tensioner can no longer take up the chain slack.
•
the chain is seized due to rust and lack of lubrication.
•
the chain climbs the sprocket teeth, especially noticeable
when turning.
To Remove the Drive Chains:
1.
Place the gearshift in the neutral position.
2.
Remove the floor pans.
3.
Remove the chain tensioner torsion springs.
4.
Roll the vehicle until the connecting link on one of the
chains is visible.
5.
Remove the cotter pins from the connecting link. Re-
move the outside plate and tap out the connecting link.
6.
Remove the chain from the vehicle.
7.
Repeat steps 3 to 6 until all drive chains are removed.
To Install the Drive Chains:
1.
Feed the chain around each sprocket and clamp the free
end with a modified vice grip (ODG part # 658-38). Fig-
ure 7-4.
2.
Install the connecting link (from the outside in) and cot-
ter pins, orienting and bending the cotter pins as shown
in Figure 7-5.
Use a pair of modified 10R Vice Grips to hold the ends
of the chain together while inserting the connecting link.
Some drive chains have no slack, and replacement of
the connecting link is difficult without this tool. Modi-
fied Vice Grips can be ordered from your CENTAUR
dealer (Part No. 658-38) or refer to Appendix 1 for
modification information.
