Front Crankshaft Bearing (Bushing) - New Holland LS140 Workshop Manual

FRONT CRANKSHAFT BEARING (BUSHING)

Inspection
Check the bearing (bushing) for peeling, melting,
seizure, or poor contact. If found to be defective,
replace.
Using a cylinder gauge and micrometer, measure the
oil clearance between the bearing (bushing) and the
crankshaft journal.
Measure the inside diameters at positions 1 and 2. At
each position, measure in both directions 3 and 4.
The oil clearance can be obtained by subtracting this
value from the maximum crankshaft journal
diameter.
Standard Oil Clearance
0.044 - 0.116 mm
(0.0017" - 0.0046")
If the oil clearance exceeds the allowable limit,
replace the bearing (bushing) or grind the crankshaft
journal and install an undersized bearing (bushing).
When replacing the crankshaft journal bushing, use
a press to install.
