Contour V6-153 2.5L DOHC (1996)
Journals, Refinishing
Dress minor imperfections such as scores, nicks or burrs with an oil stone. If the journals are severely marred or exceed the service limit, they should
be refinished to size for the next undersize bearing.
If required, machine the journals to give the proper clearance with the next undersize bearing. If the journals will not clean up to maximum undersize
bearing available, replace the crankshaft.
Always reproduce the same journal shoulder radius which existed originally. Too small a radius will result in fatigue failure of the crankshaft. Too
large a radius will result in bearing failure due to radius ride of the bearing.
After refinishing the journals, chamfer the oil holes. Polish the journal with a No. 500 grit polishing cloth and engine oil (crocus cloth may also be
used as a polishing agent) to obtain a smooth finish. Remove all grinding dust from oil passages with compressed air.
Crankshaft Sprocket
CAUTION: Handle crankshaft sprocket with care to avoid possible damage to the finished surfaces.
Inspect crankshaft sprocket for nicks, burrs or roughness that would cause premature wear. If crankshaft sprocket is worn or damaged, replace
crankshaft sprocket.
