Information:
New cylinder blocks have been introduced on the 4.236 engine for the Backhoe Loaders. They have a larger cylinder liner parent bore diameter. The outside diameter of the cylinder liner is also larger. There is no longer a flame ring on the liner. The change became effective with engine serial number LD70178U106654N. The engine serial number is located above the fuel injection pump on the block.(1) Outside diameter of cylinder liner. Earlier engines with thin wall liners: Production liner ... 103.238 to 103.264 mm (4.0645 to 4.0655 in)Service liner ... 103.188 to 103.213 mm (4.0625 to 4.0635 in)Current engines with thick wall liners: Production liner ... 104.254 to 104.280 mm (4.1045 to 4.1055 in)Service liner ... 104.204 to 104.229 mm (4.1025 to 4.1035 in)(2) Inside diameter of cylinder liner: Production liner ... 98.48 to 98.50 mm (3.877 to 3.878 in)Service liner ... 98.50 to 98.53 mm (3.878 to 3.879 in)Maximum diameter wear (when new liners are needed) ... 0.20 mm (.008 in)Transition fit of service liner in cylinder block ... 0.03 mm ( .001 in)Length of cylinder liner ... 227.10 to 227.43 mm (8.941 to 8.954 in)(3) Liner (flange) projection [do not measure from flame ring (if so equipped)] ... 0.10 mm (.004 in) above to ... 0.10 mm (.004 in) below Flange thickness of cylinder liner ... 3.81 to 3.86 mm (.150 to .152 in)Flange projection ... 0.10 mm (.004 in) above to ... 0.10 mm (.004 in) below face of cylinder block(4) Diameter of parent bore in cylinder block for liner: Earlier engines with thin wall liners ... 103.188 to 103.213 mm (4.0625 to 4.0635 in)Current engines with thick wall liners ... 104.204 to 104.229 mm (4.1025 to 4.1035 in)Depth of recess for cylinder liner flange ... 3.81 to 3.91 mm (.150 to .154 in)(5) Diameter of bore in cylinder block for camshaft No. 1 front bearing [has only front bearing (6)] ... 55.563 to 55.593 mm (2.1875 to 2.1887 in) Diameter of bearing bore for camshaft ... 50.800 to 50.843 mm (2.0000 to 2.0017 in)Diameter of bore for No. 2 journal ... 50.55 to 50.592 mm (1.990 to 1.9918 in)Diameter of bore for No. 3 journal ... 50.04 to 50.084 mm (1.970 to 1.9718 in)Clearance of camshaft in bore:Front (No. 1) ... 0.064 to 0.114 mm (.0025 to .0045 in)No. 2, No. 3 ... 0.064 to 0.135 mm (.0025 to .0053 in)Camshaft end play ... 0.10 to 0.41 mm (.004 to .016 in)Maximum permissible end play (worn) ... 0.51 mm (.020 in)(7) Diameter of bores in cylinder block for main bearings ... 80.42 to 80.44 mm (3.166 to 3.167 in)(8) Torque for main bearing cap bolts ... 245 N m (180 lb ft).Total height of cylinder block between top and bottom faces (not shown) ... 441.12 to 441.33 mm (17.367 to 17.375 in)
