Earlier Engines
(1) Cylinder head bolts and nuts tightening procedure:1. Put engine oil on the threads of bolts and nuts. Tighten all bolts and nuts in number sequence to a torque of ... 45 N m (35 lb ft)2. Tighten all bolts and nuts in number sequence to a torque of ... 95 N m (70 lb ft)3. Again tighten all bolts and nuts in number sequence to a final torque of 135 N m (100 lb ft).Retighten the cylinder head bolts and nuts after the engine has run under part load for approximately thirty minutes.a. If the bolts and nuts move before the correct final torque is reached, retighten everything in the sequence again to the final torque of 135 N m (100 lb ft).b. If the bolts and nuts do not move before the correct final torque is reached, back each one off 30 to 60° (with an 8T3052 Degree Wheel) and retighten again, in the sequence shown, to the final torque. After all the bolts and nuts are retightened, check the first 10 positions to make sure they are tightened to the correct torque.c. After 25 to 50 hours of service for a new or rebuilt engine, retorque the cylinder head bolts as shown in Step a above and adjust the valves again. New cylinder blocks have been introduced on the 4.236 engine for the Backhoe Loaders. The new cylinder blocks have deeper cylinder head bolt holes and longer bolts. The old and new sizes are shown. The change became effective at engine serial number LD70178U027631M and UP. The engine serial number is located above the fuel injection pump on the block. The new cylinder head bolts are not interchangeable between old and new blocks. All other models will have the new arrangement at first production.Later Engines
New cylinder heads have been introduced on the 4.236 engine for the Backhoe Loaders. The new 4P4722 Cylinder Head is used with a 7C3191 Head Gasket and uses a new cylinder head torque procedure. The change became effective at engine serial number LD70178U419182U and UP. The change is adaptable to engines serial number LD70178U106654N and UP. The engine serial number is located above the fuel injection pump on the block.(1) Cylinder head bolts tightening procedure:a. Check the head bolts for any distortion with a straight edge along the threads. If there is a visual reduction in the thread diameter of any threads that have not been in engagement with the cylinder block, the bolt must be replaced.b. Put engine oil on the threads of bolts. Tighten all bolts in number sequence to a torque of ... 45 N m (35 lb ft).c. Tighten all bolts in number sequence to a torque of ... 95 N m (70 lb ft).d. Again tighten all bolts and nuts in number sequence to a torque of ... 120 N m (88 lb ft).e. Turn each bolt (with an 8T3052 Degree Wheel) in number sequence an additional
