Which machines use OSR35?
The catalogue lists OSR35 in K3V63 / K5V80. The family table must be checked for the exact pump variant. A machine-family reference does not establish fitment for an individual part. Confirm the full pump code, drawing position 824 and the old part before ordering.
Is there a cross-reference or a superseded number for OSR35?
Other numbers at the same drawing position can refer to different pump models or control variants. Sharing a table or position is not evidence of interchangeability or supersession.
