CYLINDER G-HYD 8S7172 - Caterpillar

(1) Cylinder flow balance shims: 5J4776 Shim thickness ... 0.13 mm (.005 in.)Two 5J4776 Shims will change the steering time at high idle by approximately ... .05 second4J8224 Shim thickness ... 0.25 mm (.010 in.)Two 4J8224 Shims will change the steering time at high idle by approximately ... .1 second The addition of shims will cause a faster right turn (stop to stop) and a slower left turn. The result is opposite when shims are removed.(2) 9J5714 Spring for valve spool: Length under test force ... 40.6 mm (1.60 in.)Test force ... 56.2 6.0 N (12.63 1.35 lb.)Free length under test ... 55.4 mm (2.18 in.)Outside diameter ... 36.58 mm (1.44 in.)(3) 9H2367 Spring for check valve: Has no function on earlier machines and is removed on later machines.(4) Shims for flow control valve: 4J6806 Shim thickness ... 1.22 mm (.048 in.)One shim will change the steering time (stop to stop) at high idle by approximately ... 1 second(5) 2J6088 Spring (outer) for flow control valve: Length under test force ... 38.76 mm (1.526 in.)Test force ... 98.1 4.9 N (22.05 1.1 lb.)Free length after test ... 59.54 mm (2.344 in.)Outside diameter ... 20.62 mm (.812 in.)(6) 4J7490 Spring (inner) for flow control valve: Length under test force ... 41.45 mm (1.632 in.)Test force ... 59 31 N (13.3 7 lb.)Free length after test ... 50.8 mm (2.00 in.)Outside diameter ... 15.24 mm (.600 in.)(7) 2J6089 Spring for pilot valve: Color code ... yellow stripeLength under test force ... 36.25 mm (1.427 in.)Test force ... 300.6 15.1 N (67.58 3.38 lb.)Free length after test ... 44.12 mm (1.737 in.)Outside diameter ... 12.50 mm (.492 in.)(8) Pressure relief setting for steering system ... 17 225 340 kPa (2500 50 psi) Shim for pilot valve spring:3H2549 Shim thickness ... 0.25 mm (.010 in.)One 3H2549 Shim will change the relief pressure by approximately ... 340 kPa (50 psi)
