Output Shaft Coupler Lubrication
(Aurora Models Only)
Output shaft spline couplers are equipped
with a grease tting to allow lubrication to
the spline of the shaft and coupling connec-
tor. Lubricate every 25 hours with a lithi-
um based, NLGI #2 or 3 mineral oil based
grease, (such as Shell Alvania #3 or ARGO
Brand Multi-Purpose Grease Part No. 130-
105). Wipe o excess.
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 rubbing on a frame cross member.
• the chain is seized due to rust and lack of lubrication.
• the chain climbs the sprocket teeth, especially noticeable when turning.
Removing a Drive Chain
1. Place the gearshift in the N (neutral) position.
2. Remove the oor pans.
Semi-Self Adjust Chain Tensioners:
a. Turn the tensioner cam assembly in the direction which winds up the torsion spring and
push the assembly down as close as possible to the cam follower block in the bottom of
the frame. Secure it in this position with a Vice-Grip 10CR.
3. Roll the vehicle until the connecting link on one of the chains is visible.
4. Remove the spring clip from the connecting link. Remove the outside plate and tap out
the connecting link. The inside plates will be released when the connecting link is re-
moved
