11. Remove the two pull-in capscrews and
install six M42 x 140 mm LG capscrews for
the MP1000 or six M36 x 120 mm LG
capscrews for the MP800 along with their
lockwashers. Then alternately tighten each
bolt a small amount until the countershaft
box flange is tight against the frame as
shown in Views 5 and 6, Figure 4-7.

countershaft box while aligning the slots in

4.2.2 Crusher Sheave Installation (V-Belt
Drive)
To install a crusher sheave with a removable
bushing, proceed as follows (refer to Figure 4-8):
1. Refer to the oil piping drawing and install
all oil piping.
2. Remove the split tapered bushing from the
sheave by unscrewing the combination take-
up and back-off capscrews, if bushing has
not been installed on the countershaft.
3. Check that the tapered surface and bore of
the bushing, the tapered bore of the sheave
and the countershaft, are clean and free of
burrs, scratches and all foreign matter, such
as paint, dirt and lubricants.
4. Gently tap the sheave key into the
countershaft keyway with a light hammer, if
key and bushing has not been installed.
5. Loosen the clamp screw and slide the
bushing onto the countershaft aligning the
sheave key and keyway. If necessary, insert
a wedge (e.g. screwdriver) into the bushing
slit to aid in installation of bushing. Tighten
clamp screw when bushing is tight against
oil flinger.
6. Move countershaft in and out to recheck end
float. Refer to step 1 under
Countershaft Box
Assembly earlier in this section.
