front of the unit (not the operator'sposi-

tion). If the belttension is correct, reinstall the belt cover and secureit with the two

nuts.

•If the guide mark is aligned with the guide pin, or movesto the right side of the guide pin,then the belt is too loose andthe

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 allow the 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 of the unit (asviewed from operator'sposition), 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 holes in the reversead-

justable link (S, Figure5-15). Push inward on the reverseidler arm (K) and installthe clevis pin (R)through the inner holein the reverseadjustablelink (S) andout through the single hole in the reverseidler arm (K). Securethe clevis pin with the hairpin cot- ter.

8.Reinstallthe reversebelt (P,Figure5-13) onthe reverse(upper) pulley,making sure

the belt is located to the inside of the re- 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, the guide mark should againalign with or moveto the right side of the guide pin, it meansthat the reversebelt is worn beyond adjustment. Beforeinstalling a new belt, you must return the clevis pin to the OUTSIDEhole in the reverseadjustable link.

belt range; the rearmost groove is for the Low speedforward belt range.

A. Removingthe ForwardDriveBelt:

1.Stop the engine,allow it to cool and dis- connect the spark plug wire before work- ing nearthe belts.

2.Removethe reversedrive belt

following the Removing the 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 the transmission drive pulley (C,Figure 5-16) by moving it to the front of the pul- ley.

5.Pullthe forward drive belt upand off the pulleys by feeding the bottom half of the belt in betweenthe engine andtransmis- sion pulleys.

B. Installingthe ForwardDriveBelt:

1.The reversedrive belt must beremoved before installing the forward drive belt.

2.Slipthe forward drive beltdown between the rearof the engineforward drive pulley (D,Figure5-16) andfeedthe bottom half in betweenthe engineand transmission pul- leys(see Figure5-17). Besure thatthe belt is to the inside of the forward idler pulley andforward belt guide (seeJ and I, Figure 5-12).

The transmission pulley (C, Figure 5-16) has three grooves. The groove closest to the engineis for the reversebelt. The mid- dle groove is for the High speed forward
