Oil pressure regulator
Remove the oil pressure regulator (1).
Check the operation of the oil pressure regulator by pushing on the piston with a proper bar. If the piston does not operate, replace the oil pressure regulator with a new one.
Tighten the oil pressure regulator to the specified torque.
- Oil pressure regulator: 27 N·m (2.7 kgf·m, 19.5 lb·ft)
Oil pressure switch
Remove the oil pressure switch (1).
Inspect the oil pressure switch. (8-34)
Apply SUZUKI BOND to the thread part of the oil pressure switch (1) and tighten it to the specified torque.
- 99104-31140: SUZUKI BOND "1207B" (USA)
- 99000-31140: SUZUKI BOND "1207B" (Others)
- Oil pressure switch: 13 N·m (1.3 kgf·m, 9.5 lb·ft)
Note: Be careful not to apply SUZUKI BOND to the hole of the thread end.
Oil strainer
Remove the oil strainer plate (1).
Remove the oil strainer (2).
Clean the oil strainer with a compressed air.
Install the oil strainer (3).
Note: Fit the projection (A) of the oil strainer (3) in the concave portion of the crankcase.
Install the oil strainer plate (2) and tighten the oil strainer plate screw to the specified torque.
- Oil strainer plate screw: 10 N·m (1.0 kgf·m, 7.0 lb·ft)
Oil jet
Removal
Remove the oil jets (1), (2) from the left and right crankcase halves.
Remove the oil seal (3) and oil gallery plug (4).
Remove the oil jet (5) from left crankcase half.
Note: If it is difficult to remove the oil jet, use a sting.
Inspection and cleaning
Check the oil jets for clogging.
If they are clogged, clean their oil passage with a proper wire and compressed air.
- (1) Piston cooling oil jet (#13)
- (2) Oil jet (#14) (For transmission)
- (3) Oil jet (#14) (For each cylinder head)
Installation
Fit the new O-rings to each oil jets.
Caution! Use the new O-rings to prevent oil leakage.
Notes:
- Apply grease to the O-rings when installing the oil jets.
- Apply engine oil to the oil jet holes on the crankcase.
Install the piston cooling oil jets (1) to the left and right crankcase halves.
Apply a small quantity of THREAD LOCK to the bolts and tighten them to the specified torque.
- 99000-32050: THREAD LOCK "1342"
- Piston cooling oil jet bolt: 10 N·m (1.0 kgf·m, 7.0 lb·ft)
Push the oil jet into the left crankcase half until it stops.
Tighten the oil gallery plug (2) to the specified torque.
- Oil gallery plug (M8): 18 N·m (1.8 kgf·m, 13.0 lb·ft)
Gearshift arm stopper
When installing the gearshift arm stopper bolt (1), apply a small quantity of THREAD LOCK to its thread and tighten it to the specified torque.
- 99000-32030: THREAD LOCK SUPER "1303"
- Gearshift arm stopper bolt: 19 N·m (1.9 kgf·m, 13.5 lb·ft)
