Does this combo fit my OLEO-MAC GST250 pruning saw?
Yes, this OEM combo (50290192 + 25290041R) is a direct replacement for OLEO-MAC GST250, GST180, GST230 and EFCO MTT250, MTT180, MTT230 pruning chainsaws. Both pump and worm gear included — no additional parts needed.
Why buy the combo instead of just the pump?
The worm gear drives the pump from the crankshaft. If the gear teeth are worn or stripped, replacing only the pump won't restore oil delivery. The combo ensures both components are new, saving you a second disassembly later.
Is this a genuine OLEO-MAC part?
Yes, both items are genuine OLEO-MAC OEM parts with original part numbers 50290192 and 25290041R. Factory-spec quality guaranteed. We are an authorised dealer and genuine parts supplier — every component is sourced through official Emak Group supply channels.
