27.14.Inspect the yoke shaft for wear. Repair or
replace it if the bearing cones have worn into the
shaft, or if the yoke exhibits other signs of wear
or damage.
27.15.To reinstall the yoke, after complete bearing
removal, use the following steps:
27.16.Drive the bearing races into place against the
lips on each end of the bore, using an appropri-
ate drift or bearing driver.
27.17.Position the bottom bearing (cleaned, inspected,
and packed) in it’s race, and secure it by press-
ing a new seal in behind it.
27.18.Drive the seal flush with the bottom edge of the
bore using a seal driver or a 2X4.
27.19.Lubricate the lip of the seal with grease or oil,
and position the lower spacer in the seal. If the
spacer has a wear ring on the sealing surface, it
may be reversed, or swapped with the upper
spacer. See Figure 27.19.
27.20.Insert the yoke shaft up through the lower spacer
and bearing.
27.21.Install the cleaned, inspected and freshly packed
upper bearing over the shaft, followed by the
upper spacer and castle nut.
27.22.Support the yoke while tightening the castle nut.
27.23.Tighten the nut until all vertical play in the yoke
shaft has just been taken-up, then align the
nearest serration on the nut with the cross-bore
in the yoke shaft.
27.24.Secure the nut with a new 5/32” X 1 1/4” cotter
pin, and reinstall the grease cap.

27.25.Front axle removal can be done with the cutting
deck in-place, if the mower and deck are prop-
erly supported.
27.26.Remove the grease caps and cotter pins from
each of the front caster yokes.
27.27.Loosen, but do not remove the castle nuts that
secure the caster yokes, using a 1 1/8” wrench.
27.28.Lift and safely support the mower by each side
of the frame, behind the front axle.
27.29.Support the cutting deck by the reinforced front
lip, just inside of each front deck gauge wheel.
This will take the weight off of the front lift rod.
See Figure 27.29.
27.30.Remove the caster yokes to make the front axle
easier to handle. See Figure 27.30.
