Cylinder Assemblies

(b) Coat pistons with lubriplate or engine

oil and stagger the four piston ring gaps 90

degrees apart.

(2) C y l i n d e r

assemblies.

Note. For instructional purposes, the in-

stallation of only one cylinder assembly is

described. The remaining cylinder assemblies

should be installed in the same manner.

Note. Wash cylinder bores thoroughly just

prior to engine assembly, using a power brush

with hot (160 F) soap water. Cylinder bores

should then be oiled to prevent rust.

(a) Rotate engine overhaul stand until

right bank cylinder holes, with connecting rod

Nos. 1R through 6R.

(b) Install piston with rings in cylinder

and cylinder assemblies on crankcase following

instructions which accompany figures 7-12 and

7-13.

1. Install piston and rings (A) in cylinder assembly using

c o m p r e s s o r and gage-4910-795-7956. The piston

position number (fig. 7-11) must always correspond to

the cylinder number marked on intake valve side of

valve rocker arm cover flange. The arrow on the piston

boss must he directed toward the exhaust port outlet.

Guide piston and rings into cylinder until all piston

rings have entered the cylinder bore. Slide the com-

pressor f r o m p i s t o n a n d r i n g a s s e m b l y . I n s t a l l

remaining pistons in cylinders in the same manner.

2. Install new preformed packing (B) on each cylinder base

making sure that packing is not twisted or otherwise

improperly seated.
