KM-470-B
Angular Torque Gage
Crankshaft - Inspection Procedure
- Coat the crankshaft bearings with engine oil.
- Install the upper crankshaft bearings into the engine block crankshaft journals.
- Install the lower crankshaft bearings into the crankshaft bearing caps.
- Install the crankshaft.
- Inspect the crankshaft end play with the crankshaft bearings installed.
- Check for permissible crankshaft end play. Refer to
Engine Mechanical Specifications
.
- With the crankshaft mounted on the front and rear crankshaft bearings, check the middle crankshaft journal for permissible out-of-round (runout). Refer to
Engine Mechanical Specifications
.
Important: Grease the crankshaft journals and lubricate the crankshaft bearings slightly so that the plastic gaging thread does not tear when the crankshaft bearing caps are removed.
- Inspect all crankshaft bearing clearances using a commercially available plastic gaging (ductile plastic threads).
- Cut the plastic gaging threads to the length of the bearing width. Lay them axially between the crankshaft journals and the crankshaft bearings.
- Install the crankshaft bearing caps.
- Install the crankshaft bearing cap bolts.
Tighten
Tighten the crankshaft bearing cap bolts to 50 N·m (37 lb ft). Using
KM-470-B
(1), tighten the crankshaft bearing cap bolts
another 45 degrees plus 15 degrees.
- Remove the crankshaft bearing caps.
- Measure the width of the flattened plastic thread of the plastic gaging using a ruler. (Plastic gauging is available for different tolerance ranges.)
- Inspect the bearing clearances for permissible tolerance ranges. Refer to
Engine Mechanical Specifications
.
Connecting Rods - Inspection Procedure
- Coat the connecting rod bearings with engine oil.
- Install the upper connecting rod bearings into the connecting rod journals.
- Install the lower connecting rod bearings into the connecting rod bearing caps.
Important: Grease the connecting rod journals and lubricate the connecting rod bearings slightly so that the plastic gaging thread does not tear when the connecting rod bearing caps are removed.
- Inspect all of the connecting rod bearing clearances using a commercially available plastic gaging (ductile plastic threads).
- Cut the plastic gaging threads to the length of the bearing width. Lay them axially between the connecting rod journals and the connecting rod bearings.
- Install the connecting rod bearing caps.
Notice: Refer to Fastener Notice in the Preface section.
- Install the connecting rod bearing cap bolts.
Tighten
Tighten the connecting rod bearing cap bolts to 35 N·m (26 lb ft). Using
KM-470-B
(1), tighten the connecting rod bearing cap bolts another
45 degrees plus 15 degrees.
- Remove the connecting rod bearing caps.
- Measure the width of the flattened plastic thread of the plastic gauging using a ruler. (Plastic gaging is available for different tolerance ranges.)
- Inspect the bearing clearance for permissible tolerance ranges. Refer to
Engine Mechanical Specifications
