I nstall Rotor in Rotor Housing
Equipment Necessary: High-Temperature Grease
(Bosch Ft1v4 or Ft1v8)
1. Carefully slide the rotor (gear side down)
onto the mainshaft and pinion gear.
e
CAUTION
e
Make sure that sealing components do not
accidentally fall out of the rotor when installing
rotor in rotor housing. Damage to the end
cover(s) and/or rotor housing will occur if
components were allowed to fall out of the
rotor and complete engine assembly performed.
2. Insert high-temperature grease (Bosch Ft1v4
or Ft1v8) into the sealing pin bores and side
seal grooves.
3. Insert 2 sealing pin springs into each sealing
pin bore . Perform this step on all sealing
components.
II
Note: Sealing pin springs must have the
convex sides touching to ensure maximum
spring compression. Open end of the sealing pin
springs must line up with the apex seal groove.
4. Insert the sealing pin into the sealing pin bore.
Line up sealing pin by running an apex seal
through the groove. Perform this step on all
sealing components.
5. Install the side seal springs into the grooves;
spring ends are to point toward the rotor.
I nstall side seals in grooves, Fig.
11-49.
Per-
form this step on sealing components.
6. Lubricate the apex seal end piece with
high-temperature grease (Bosch Ft1v4 or
Ft1v8) and slide the end piece into the apex
seal groove.

7. Place the apex seal with spring on the apex
seal end piece and slowly push all components
down the groove, Fig. II-50. Install remaining
apex seal end pieces, apex seal springs and
apex seals in the same manner.

Install PTO End Cover and Counterweights
Equipment Necessary: Oil, Mounting Sleeve, 10
mm Socket, 11 mm Wrench and Torque Wrench
1. Lubricate the PTa end cover sliding surface
and bearing with oil.
2. Place the mounting sleeve on the mainshaft
and slide the PTa end cover over the
mainshaft. Ensure the PTa end cover slides
onto the rotor housing dowel pins, Fig. II-50,
and is firmly sealed around the rotor housing
sealing surface.
3. Secure the PTO end cover, rotor housing and
Magneto end cover together with 10 bolts,
flat washers and nuts, using a 10 mm socket
and wrench, Fig. II-51. Tighten the nuts to
5.8 - 8.0 ft. Ibs. torque, using a torque
wrench.
