Reverse disassembly procedure for assembly, noting the following.
1) Apply power steering fluid to shaft (2) outer surface and grease to oil seal lip (1) and insert it from oil seal side.
“A” : Grease 99000–25010 ( SUZUKI Super Grease A )
2) Apply power steering fluid to O-rings and fit them to pump body.
3) Install side plate (2) to pump body.
NOTE:
Carefully align the dowel pins (3) on the side plate (2) at bolt hole (1) as shown in the figure.
4) Apply power steering fluid to sliding surface of rotor (1).
5) Install rotor (1) to shaft, directing “dot” (2) marked side of rotor toward pump cover (facing up).
6) Install new snap ring to shaft, then make sure to fit snap ring into shaft groove securely.
NOTE:
Never reuse the removed snap ring.
7) Apply power steering fluid to sliding surface of cam ring (1).
8) Install cam ring (1) to pump body. The tapered end of cam ring (1) should face the side plate (2).
9) Apply power steering fluid to each vane (2).
10) Install vanes (10 pipes) (2) to rotor (1).
11) Apply power steering fluid to O-ring (1) and fit it to pump body.
12) Install O-ring (1) to pump body.
13) Apply power steering fluid to sliding surface of pump cover (1) and rotor.
14) Match the dowel pins (2) to the holes of the cover plate as shown and install pump cover to pump body.
15) Tighten pump cover bolts to specified torque.
NOTE:
After installing pump cover (1), check to make sure that shaft can be turned by hand.
Tightening torque

16) Apply power steering fluid to relief valve (flow control valve) (1).
17) Install relief valve (flow control valve) (1) to pump body.
NOTE:
Check that relief valve (flow control valve) slides smoothly.
18) Apply power steering fluid to O-ring of plug (3).
19) Install O-ring to plug (3).
20) Tighten plug to specified torque.
Tightening torque
Plug ( a ): 60 N·m ( 6.0 kg-m, 43.5 lb-ft)
2. Flow control valve spring
21) Apply power steering fluid to O-rings of pressure switch (1).
22) Install O-rings to pressure switch (1).
23) Install pressure switch (1) to pump body.
Tightening torque
Pressure switch ( a ): 28 N·m ( 2.8 kg-m, 20.0 lb-ft)
24) Apply power steering fluid to O-ring (2) of suction connector (1).
25) Install O-ring (2) to suction connector (1).
26) Install suction connector (2) to pump body as shown in the figure. Tighten suction connector bolt (3) to specified torque.
