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.

Q: How to service and repair the crankshaft on Ford Mustang?
A:
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.
