3. Movetheaxlebushinginorouttothe
desiredposition.
4. Torquethejamnutsto40‐45ft‐lbsto
securetheaxlebushingtotheaxle
mountingplate.
5. Reinstalltherearwheelontothe
wheelchair.Referto

Adjusting Wheelbase Length
NOTE:Forthisprocedure,refertoFIGURE11.9onpage76.
NOTE:Thewheelbasecanbeadjustedin¼inchincrements.
NOTE:Lengtheningthewheelbasewillincreasestabilityandmaintainstandardmaneuverability
ofthewheelchair.
NOTE:Shorteningthewheelbasewilldecreasethestability,increasemaneuverabilityand
distributeadditionalweightontotherearwheels.
1. Removetherearwheelfromthewheelchair.RefertoRemoving/InstallingRear
Wheelsonpage 67.
2. Removethetwotopmountingscrews,washersandlocknutssecuringtheaxle
mountingplatetothewheelchairframe.
3. Removethetwobottommountingscrewswasherscamberspacers(ifpresent)and
locknutssecuringtheaxlemountingplatetothewheelchairframe.
NOTE:Framemountingpositionsarespaced½inchapart.
4. Align
theaxlemountingplatemountingholeswiththedesiredframemountingholes.
5. Usingthetwotopmountingscrews,washersandlocknuts,looselysecuretheaxle
mountingplatetothewheelchairframe.
6. Usingthetwobottommountingscrewswasherscamberspacers(ifpresent)and
locknuts,looselysecuretheaxlemountingplatetothe
wheelchairframe.
NOTE:Theaxlemountingplatemountingholesareoblongandcanbeusedtofinetunethe
wheelbasemeasurementby¼inch.
7. Positiontheaxlemountingplatetowardsthefrontorrearofwheelchairtoobtainthe
desiredwheelbasemeasurement.
8. Securelytightenmountinghardware.
