NOTICE
When the nut that holds the compressor wheel is
loosened, do not put a side force on the shaft.
3.
Install tool (C) in tool (B), and put the cartridge
assembly in tool (C) as shown. Use tool (D) to remove
the nut that holds compressor wheel (6).
NOTICE
The compressor wheel can often be removed from
the cartridge assembly without the use of the oil
cooker. The oil cooker can be used for easier
disassembly. If removal of the compressor wheel is
too difficult, damage to parts can be the result.
The oil used to heat the compressor wheel must
have a flash point (the temperature at which the oil
will burn) above 204°C (4000F).
4.
Install tool (H) on tool (E). Heat tool (E) to a
temperature of 1760C + 140C (3500F + 250F). Install the
cartridge assembly on tool (H) so only the compressor
wheel is in the oil. Heat the compressor wheel for no
more than ten minutes.
