What happens when oil is applied to the end of a crankshaft?
This is similar to what happens when a thrust load is applied to the end of a crankshaft and oil squeezes out from between the shaft and bearing surfaces. If that load is excessive, the oil film collapses and the surfaces want to stick together resulting in a wiping action and bearing failure.
What does the actuator do on a fork?
The actuator pushes on the outside cup of the fork (shown here by the spacer below the fork) and overcomes the force of the fork’s spring. The fork then slips into the position shown below, pushing the collar over to engage both the inner and outer gears. This locks the left and right wheel shafts together.
What causes a crankshaft thrust bearing to wear out?
A number of factors may contribute to wear and overloading of a thrust bearing, such as: 1. Poor crankshaft surface finish. 2. Poor crankshaft surface geometry. 3. External overloading due to. a) Excessive Torque converter pressure. b) Improper throw out bearing adjustment.
What should I do if my crankshaft bearings are not aligned?
Tighten main cap bolts to approximately 10 to 15 ft.lb. to seat bearings, then loosen. Tap main cap toward rear of engine with a soft faced hammer. Tighten main cap bolts, finger tight. Using a bar, force the crankshaft as far forward in the block as possible to align the bearing rear thrust faces.

What causes oil to lean past the seals?
Both Situations can Cause oil to Lean Past the Seals. Oil Pressure. The Oil Pressure Being Too Low, will Cause The Turbo To Wear the Internal Parts of the Turbo. Usually Once the turbo develops some In and Out Shaft play the Seals get Worn out in the Process, Which makes the Turbo Need a Rebuild.
Why does a journal bearing turbo blow oil?
Having and Oil Restrictor in a Journal Bearing Turbo can Causes Turbos to Eventually to Blow oil, Because it Starves the Turbo Of Oil, Which Causes the Internals of the Turbo to Wear out (including the Seals). Don’t Use a Restrictor with a Journal Bearing Turbo, if You think the OIl pressure is “Too High” Then a Drain with a Larger Inside Diameter.
Can you use a restrictor on a journal bearing turbo?
Don’t Use a Restrictor with a Journal Bearing Turbo, if You think the OIl pressure is “Too High” Then a Drain with a Larger Inside Diameter. Hot Shut Offs.
