Before attempting to dismantle the traction motor, drain all
oil, blank all inlet and outlet ports and wash the outer

Dry using compressed air.
1 Loosen, but do not remove plug 204 and the two
sleeves 202 in relief valve body 212.
2 Unscrew the four socket head bolts 170 and remove
relief valve body 212 from rear flange 101. Remove the
two ‘O’-rings 156 from the rear flange and discard.

Make different alignment marks across each sub assembly
joint faces as an aid to assembly.
The cylinder block assemblies, servo pump, relief valve and

shims. Take care to reassemble in the same manner.
