PUMP GP-PISTON 4505374 - Caterpillar

The radius of the crankshaft must meet the specifications as found in the Reuse and Salvage Guideline specifications for the respective engine platform to be reused. Refer to the ""References"" section found within this document for a list of specification Reuse and Salvage Guidelines.Note: The appropriate engine platform Reuse and Salvage Guideline specification contains dimensions of radii before the peening operation. Refer to the ""References"" section found within this document for a list of specification Reuse and Salvage Guidelines. When possible, measure the fillets before the peening operation. Refer to Reuse and Salvage Guideline, SEBF8039, "Crankshaft Visual Inspection and Magnetic Particle Inspection" for crankshaft inspection information.Procedure for Bracket Checking the Radii of the Journal Fillet
The bracket check should be used when the exact gauges cannot be found. It will be necessary to measure the radius of the fillet by using other gauges that have a larger radius and smaller radius than the specified fillet. Refer to the following example.
Use a gauge that is smaller than the radius of the fillet. The nose of the gauge should contact the contour of the fillet. Refer to Illustration 35. If the shoulders of the gauge contact the fillet, then the gauge is larger than the fillet.
Use a gauge that is larger than the radius of the fillet. The nose of the gauge should not contact the contour of the fillet. Refer to Illustration 36. If the nose of the gauge contacts the fillet, the gauge is smaller than the fillet.
The bracket check method should show that the radius of the fillet is between the gauges. The crankshaft will give normal performance if the selected gauges are close to the specified radius of the fillet. The crankshafts must also meet the other physical requirements.Special Checking Procedure for Specific Crankshafts
The following information is used to check the radius of the rod and the main fillet. This information is only used for 1W-0400, 0R-5560, 0R-5474, AND 0R-5164 crankshaft.
Illustration 37 g01401227
Checking the radius of the rod (9) Max Point of Tangency with Sidewall (10) Typical ProfileThe profile of the fillet must fall within Zones (A, B, and C) .The minimum radius in Zone (C) is 0.76 mm (0.030 inch).The minimum radius in Zone (B) is 4.88 mm (0.192 inch).The minimum radius in Zone (A) is 0.76 mm (0.030 inch). Double fillet intersection may occur in Zone (A). The intersection may contain a sharp peak. Refer to item (10) .
