IMPORTANT
• Use only the transmission fluid (See page G-8), in no case use mixture of oils of different brands.
• Before disassembling the power steering system hydraulic components, check the performance of
hydraulic pump and power steering using a flowmeter.
Do not disassemble the power steering needlessly.
• After removing or disassembling the power steering hydraulic components, be sure to bleed air.
• If disassembly of power steering is needed, perform disassembly carefully following the instructions given
below.
1. Since the sliding surfaces of those parts have seen precisely finished, do not brush or grind with
sandpaper. Use transmission fluid for cleaning and compressed air for blowing off.
2. When reassembling, inspect each part for wear and damage. If seriously damage, replace parts as sub-
assembly or assembly.
It is desirable to replace O-rings and seals with ones.
