10-8.7. IOF-550-B & C Engine Cylinder Installation 

Procedure

 

1.

 

Refer to Figure 10-59; install a new cylinder base O-ring (25) lubricated with aviation 
engine oil. (Verify the cylinder base O-ring is free of cracks and deformities.) 

2.

 

Install the valve rocker shafts (18) in the cylinder rocker shaft bores prior to installing 
the cylinders.  

3.

 

Verify the cylinder valve keepers have been properly installed. 

4.

 

Thoroughly clean the cylinder deck and stud threads with Stoddard solvent; use a 
narrow brush to clean stud thread holes. The deck and stud holes must be free of all 
dirt and debris. 

5.

 

Lubricate all cylinder through bolt and deck stud threads using clean 50 weight 
aviation engine oil.  

6.

 

Verify the piston rings (49 to 52) have been partially installed in the cylinder barrel 
and that a new cylinder base O-ring (25) has been installed at the cylinder base. 

CAUTION: When installing the connecting rod, use care not to drop 
the connecting rod on the cylinder deck to avoid damaging and 
having to replace the cylinder.  

7.

 

Carefully rotate the crankshaft placing the connecting rod of the cylinder being 
installed in the outer most position. Remove the connecting rod support O-ring. 

8.

 

Back the piston pin (53) out far enough to allow the piston (48) to be installed on the 
connecting rod. 

9.

 

Place the cylinder and piston (48) on the connecting rod.  

10.

 

Align the piston with the connecting rod and slide the piston pin into the connecting 
rod. 

11.

 

Using a ring compressor, compress the fourth piston ring and push the cylinder until 
the fourth piston ring is positioned inside the cylinder barrel.  

12.

 

Remove the ring compressor and push the cylinder assembly against the crankcase 
cylinder deck with the stud holes aligned. 

13.

 

While supporting the cylinder, install, but do not torque, the cylinder flange nuts (40 
& 41). 

14.

 

Install the 7th stud brackets (42 & 43) and nut (44). The 7th stud nuts have a conical 
seat. 

15.

 

Torque the cylinder fasteners according to section 10-8.10 “Cylinder Torque.” 

16.

 

Install the hydraulic tappets and pushrod tubes according to instructions in Section 
10-8.12.  

17.

 

Install the Valve Mechanism and Pushrods according to Section 10-8.13. 

18.

 

Install the spark plugs and ignition harness according to the “Ignition System 
Maintenance” section of Chapter 9.
