PN 4-16-375, Yak 52 Oil Hose, Strainer to Oil Pump
This Fire Sleeved drop-in replacement hose runs from the top of the Oil Strainer low on the starboard firewall to the Oil Pump inlet. (This engine compartment photo is taken looking up and back from behind the #6 exhaust stub)
New Russian hose material meeting the factory specifications has been used, plus good-condition used Russian hose fittings.
This part should be installed on a Yak 52 with an M14-P series motor and standard factory equipment in the engine bay. No fitness for use should be assumed if this hose is installed on any other engine/airframe combination.
Fit this hose with confidence. Depending on airplane duty, Russian AD’s approved this hose material for use in service for between 7 to 9 years.
Once you've fitted this new hose, don't throw your old one away ! If the Original Russian hose fittings on your old hose are in good shape, please cut the ends off and ship them to us.
For each well cared-for RUSSIAN metric hose-end fitting, once received, inspected and deemed acceptable by us we'll send you an electronic refund (not to exceed $15 US per hose end) .
