tion). If the belttension iscorrect, reinstall
the belt cover and secureit with the two
nuts.
• If the guide mark is aligned with the
guide pin,or movesto the right sideof the
guide pin,then the belt is too looseandthe
tension must be readjustedas described
next.
3. The reverseidler pulley (L,Figure5-13)
regulatesthe tension that is appliedto the
reversedrive belt (P). The following ad-
justment will allowthe reverseidler pulley
to apply more tension to a loose belt.
4. Removethe belt cover.
5. Slipthe reversebelt (P,Figure5-13) off
the engine-driven reverse (upper) pulley.
6. Onthe right side ofthe unit (asviewed
from operator's position), removethe hair-
pin cotter from the clevis pin (R, Figure 5-
13) that connectsthe reverseidler arm(K)
to the reverseadjustable link. Push inward
on the reverseidler arm (K) and remove
the clevis pin (R).
7. There aretwo holesin the reversead-
justable link (S, Figure5-15). Pushinward
on the reverseidler arm (K) and installthe
clevis pin (R)through the inner holein the
reverseadjustablelink (S) andoutthrough
the single hole in the reverseidler arm (K).
Securethe clevis pin with the hairpin cot-
ter.

verse idler pulley (L, Figure 5-13).
9. Reinstallthe belt cover and secure it
with the two nuts.
IMPORTANT: If, in future tests for
reversebelttension, theguide mark
should againalign with or moveto the
right side of theguide pin, it meansthat
the reversebelt is worn beyond
adjustment. Beforeinstalling a new belt,
you must return the clevis pin tothe

A. Removingthe ForwardDriveBelt:
1. Stop the engine,allow it to cool and dis-
connect the spark plug wire before work-

2. Removethe reversedrive belt
following the Removingthe ReverseDrive
Beltinstructions in this section.
3. Movethe forward drive belt (B,Figure
5-16) completely off the engineforward
drive pulley (D).
4. Slip the forward drive belt completely
off thetransmission drive pulley (C,Figure
5-16) by moving it to the front of the pul-
ley.
5. Pullthe forward drivebelt upand off the
pulleys by feeding the bottom half of the
belt in betweenthe engine andtransmis-
