These numbers following the model designation, 5F or 5H, indicate the numbers of cylinders. For example, the 5F40 has four cylinders and the 5H120 has twelve cylinders. Since the construction of 5F and 5H compressors is similar for all sizes, assembly and disassembly procedures are the same. In addition, interchangeability of parts within each line, 5F or 5H, simplifies the service and parts problems. The use of cylinder sleeves makes it unnecessary to rebore a cylinder or replace the crankcase if a cylinder wall is scored or worn excessively. It is only necessary to replace the sleeve. Capscrew and pipe plug sizes are standardized to reduce the number of tools required for service. Handhole covers or bottom plates of adequate size make it easy to reach the inside of the crankcase. Table 1 shows the major parts that are interchangeable. Table 2 gives the torque values for tightening bolts.

SERVICE TOOLS The following tools are needed in addition to the tools normally carried by the mechanic: 1. 5F20-2061 Suction Valve Clips.! Used when valve plates are assembled on compressors. See 2. 5H40-2061 Suction Valve Clips. J Page 22 for usage. *3. 5F20-932 Bearing Puller Assembly. Used to remove the seal end main bearing. See Page 36 for usage. *4. 5F20-572 Cylinder Sleeve Puller.7 Used to remove cylinder sleeves from compressors. See *5. 5H40-572 Cylinder Sleeve Puller, j Page 24 for usage. 6. Elongated Socket. Used to remove the internal relief valve from early 5H60 compressors. See Page 21 for details. *7. 5F20-A322 SPIG. Used to predict the remaining bearing life without disassembling the compressor. Instructions are included with the SPIG. *Obtain from Robinair Manufacturing Corp., Edgerton, Ohio. 5 5F,H SERVICE Carrier TABLE 3 - WEAR LIMITS FOR 5F COMPRESSORS Factory Maximum F actory Minimum Maximum wear Before Repair Part Name 5F30-30 5F40-60 5F20-30 5F40-60 5F20-30 5F40-60 SEAL END Main Bearing Diam.
