V8 CYLINDER ENGINE Check crankshaft bearings 22. Locate t h e bearing upper shell into the connecting- rod. 23. Locate the connecting-rod and bearing on to the applicable crankshaft journal, noting that t h e on t h e connecting-rod must face towards the front of the engine on the right-hand 24. When both connecting-rods are fitted, the bosses will face inwards towards each other. 25. Place a piece of Plastigauge across the centre of the lower half of the crankshaft journal. 26. Locate the bearing lower shell into the connecting- rod cap. 27. Locate the cap and shell on to the connecting-rod. Note that the on the edge of the cap must be the bearing connecting-rod. 28. Secure the connecting-rod cap, and tighten to the shells must be retained in sets, and in the correct , correct torque. .... 29. Do not rotate the crankshaft or connecting-rod 30. Remove the connecting-rod cap and shell. printed on the Plastigauge packet, measure t h e flattened Plastigauge at its widest point. 32. The graduation that most closely corresponds to the width of the Plastigauge indicates the bearing clearance. 33. The correct bearing clearance with new or overhauled components is 0,013 to 34. If a bearing has been in service, i t is advisable to fit a new bearing i f t h e clearance exceeds (0.003 35. I f a new bearing is being fitted, use selective assembly to obtain the correct clearance. 36. Wipe off the Plastigauge with an oily rag. DO NOT scrape i t off. while the Plastigauge is in Assembling pistons to connecting-rods 37. If an hydraulic press and tool 605350 was used for dismantling, refit piston to its connccting-rod as follows: a. Check that the base of tool 605350 and the guide tube are fitted as follows:- tool 605350 on the bed of a n hydraulic press which has a capacity of 8 tons (8 tonnes). Fit the guide tube into the bore of the base with its countersunk face uppermost. c. Fit the connccting-rod into the piston with the if the original pair arc being used, t h e n place the piston and connecting-rod tube. Fit the gudgeon pin into the piston up to e. Press i n the gudgeon pin until it abuts the shoulder of the long mandrel. continucd 107 |
