1. All 450-series tillers use a simple control lever to
move the shift control rod. The selector is locked into
position by the internal detentes in the chain case.
See Figure 2.18.
• The same bolt that holds the shift control lever to
the upper handlebar also holds a nut retainer
strap.
• The nut retained by the strap is for the handlebar
height adjuster.
• The upper handlebar and the shift control lever
pivot on the same bolt: adjusting the handlebar
height does not effect the shift control lever.
2. A service kit (753-06491) for 2010 tillers converts this
lever to lock positively in the Tines Reverse tilling
position. Production continues with the simple control
lever. See Figure 2.19.
• The kit lever includes an angled plate that locks
into a notch in a bracket.
• A pair of hex-head cap screws hold the plate to the
lever. This provides adjustment to coordinate the
lever lock position with the internal detentes in the
chain case.
• A compression spring on the pivot bolt allows lat-
eral movement of the lever to engage or disen-
gage the lock notch.
3. The control rod connects the shift control lever on the
handlebar to the shift crank/pointer on the chain
case.
• The rod is fastened at both ends by a pair of hair-
pin clips and flat washers.
• Orientation of the rod is not critical, but it is gener-
ally positioned to the inside of the shift control
lever, so that it rides directly over the handlebar.
4. On 450 Series tiller produced before the 2010 pro-
duction season, the shift crank/pointer has a straight
bore, and is held to the shift fork by a roll pin. To
remove it: See Figure 2.20.
4a. Disconnect the shift rod
4b. Drive-out the roll-pin using a pin punch.
