Crankpins that are worn out of round tapered or badly scored should either be discarded or perhaps salvaged by grinding undersize hard chrome plated and finish ground to above diameter Connecting rod cap bore must be perfectly round and within above sizes and free of taper Discard if elliptical or tapered as the result of abnormal heating Each cap and rod is match marked for correct identification Take care that each cap is reinstalled properly with its companion rod Bearing halves are identical and are prevented from rotating by tongues which fit into slots in the cap Check that all oil holes are clean and fully open Grit is the greatest enemy of bearings however precisely manufactured Hence all surfaces must be perfectly clean and lightly oiled prior to assembly Remove any burrs or sharp corners which prevent the perfect fitting of these precision bearings Using a torque wrench tighten cap bolts as follows Thread Size 5 16 18 UNC Tightening Torque 19 Ft Lb Thread Size 3 8 16UNC Tightening Torque 26 Ft Lb Thread Size 1 4 20UNC Tightening Torque 11 Ft Lb Specified torque applied to clean well oiled threads and bearing faces will create tensile stresses in the cap bolts from 90 000 to 110 000 psi approx and will provide correct initial tension Myers Aplex Series pumps use high strength cap bolts suitable for these initial loadings maintained b

SAFETY SHUTDOWNS Carefully check all electric shutdown devices present such as crankcase oil level discharge pressure vibration lubricator oil level motor thermostat etc CRANKSHAFT ASSEMBLY GENERAL Myers Aplex Series crankshaft suspension uses two single row tapered bearings which are shim adjusted to provide the correct running clearance Thorough cleaning of all components prior to assembly is essential Power frame shaft bearings and retainer must be scrubbed with clean solvent such as kerosene before starting Remove any oil dirt rust and foreign matter which might prevent the correct fit up Crankshaft journals are critical Remove all burrs rust spots and nicks paying special attention to the ground areas on which bearings and oil seals operate TAPERED ROLLER BEARINGS Shaft and frame tolerances provide a tight shrink fit on the shaft and in the carrier The best way to install the cone assembly consists of the inner race cage and rollers on the shaft is to heat the cone assembly electric oven for 30 minutes at 300 to 400 F No more Do not heat bearings with an acetylene torch This ruins the bearings Using clean insulated gloves remove the hot cone assembly from the oven promptly dropping it on to the shaft The cone assembly must contact the seat thrust face not be cocked and the large end of the rollers must be down Do not hammer on the bearing The soft steel
