METHOD 2 CHALK
1. Place machine on a smooth level surface.
2. Set handlebars in a straight ahead position and
secure handlebars in this position. NOTE: The
steering frog can be used as an indicator of whether
the handlebars are straight. The frog should always
point straight back from the steering post.
3. Place a chalk mark on the face of the front tires
approximately10 (25.4cm)fromtheflooras closeto
the hub/axle center line as possible. NOTE: It is
important that both marks beequally positionedfrom
the ground inorderto getanaccuratemeasurement.
4. Measurethe distancebetween themarks andrecord
the measurement. Call this measurement “A”.
5. Rotatethetires180° bymovingvehicleforwardorbackward. Positionchalkmarksfacingrearward, evenwith
the hub/axle centerline.
6. Again measure the distance between the marks and record. Call this measurement B”. Subtract
measurement B” from measurement “A”. The difference between measurements A” and “B is the vehicle
toe alignment. The recommended vehicle toe tolerance is 1/8 to 1/4 (.3 to .6 cm) toe out. This means the
measurement atthefront of thetire(A)is1/8 to1/4 (.3to.6cm) widerthanthemeasurement atthe rear(B).
TOE ALIGNMENT ADJUSTMENT
7. If toe alignment is incorrect, measure the distance between vehicle center and each wheel. This will tell you
which tie rod needs adjusting. NOTE: Be sure handlebars are straight ahead before determining which tie
rod(s) need adjustment.
CAUTION: During tie rod adjustment it is very important that the following precautions be taken when tightening
tie rod end jam nuts. If the rod end is positioned incorrectly it will not pivot, and may break.
To adjust toe
alignment:
S Hold tie rod end to keep it from rotating.
S Loosen jam nuts at both end of the tie rod.
