NOTICE
Replace used wheel bolt
If a wheel bolt is removed for tire service, replace it with a new, unused bolt
from Permobil and tighten it to the recommended torque. Also, inspect the
drive axle and wheel rim for any damage. Damage to either part can cause
the wheel bolt to loosen or fracture. Because the TUF-LOK thread lock fluid
wears off, Permobil recommends that wheel bolts only be used once.
1. Check that the wheel shaft and rim are undamaged. Clean to
remove dirt and rust. Replace damaged parts.
2. Fit the spacer (A) on the axle.
3. Install the wheel (B) on the axle by hand without using any tools.
Make sure the rim is fully seated on the axle.
4. Use the screw (D) and washer (C) to install the wheel (B); do so by
hand without using any tools.

17.7 lb.ft. Do not use a pneumatic impact wrench.
