How to service and repair the crankshaft on Ford Mustang?

The crankshaft servicing process starts with measuring two distinct directions of each main bearing journal diameter for the crankshaft. The next step involves diameter measurement of the main bearing journals in two directions at both ends. Check the journal clearance only after making sure all crankshaft main bearing journals meet the specified requirements. Use Plastigage(R) to check each crankshaft bearing surface by placing it directly on the bearing faces after removing the crankshaft main bearing and its caps. Users must avoid any rotation of the crankshaft while performing this procedure before proceeding to measure the crankshaft journal clearance with the crankshaft main bearing cap removal and installation. You should measure crankshaft end play using a Dial Indicator Gauge by placing the crankshaft in the rear position of the cylinder block while zeroing the indicator before moving it to the front to get and document the end play measurement. A Dial Indicator Gauge measures crankshaft runout by rotating the crankshaft to obtain readings which need subtraction of the lowest dial indicator value from the maximum one. Perform this test after verifying that the main bearing journals meet their specifications.

How to service and repair the crankshaft on Ford Ranger?

The first step for crankshaft service and repair procedures includes compassing the crankshaft main bearing journal diameters from two directions for spec compliance. Measure the diameter across two directions at both ends of the crankshaft main bearing journals to evaluate their taper and out-of-round dimensions. After taking off the crankshaft main bearing caps and main bearing you should place Plastigage(R) on each main bearing surface without rotating the crankshaft. Check the crankshaft journal clearance by reinstalling the main bearing cap after Plastigage(R) assessment and removal. The Dial Indicator Gauge enables end play measurements through placing the crankshaft at the cylinder block's rear position before zeroing the indicator which allows recording the end play when moving the crankshaft to the front. The Dial Indicator Gauge should be used to check crankshaft runout after verifying the main bearing journals are in spec. During measurement the crankshaft should be rotated while the lowest reading is subtracted from the highest. The end of your procedure requires assessment of connecting rod bearing journal taper and out-of-round by measuring the diameters across two perpendicular directions at each end while maintaining measurements within specified wear limits.
