Servicing Dh10A, 245, 285 - Volvo DH10A 245 Service Manual

Turbocompressor, repairs
Important!
Refers to repairs to turbo on DH10A, 245, 285.
The wastegate with pressure box and bracket is not to
be removed from the turbine housing. Nor is the lock
nut on the push rod to be released. But, if it has to be
released, the push rod must be adjusted, in which case
refer to Checking wastegate opening pressure.
If the pressure box has to be replaced, use the repair kit
for this (see Parts Catalogue). The kit contains a service
tool (fixture) and necessary instructions for a correct
mounting of the wastegate.
Always line-up mark the position of the turbine hous-
ing (1) in relation to the compressor housing (2) before
disassembling.
Remove:
– Compressor housing (5).
– Bearing housing (4), compressor wheel (6) and turbine
wheel (7). Avoid damage to the wheel blades.
