Yak 52 Oil Hose, Oil Pump Scavenge to Oil Cooler , PN 4-16-410
This drop-in replacement hose runs from the Oil Pump outlet through a grommet in the firewall en route to the Oil Cooler under the Starboard Wing. Aft of the Firewall it connects to rigid tubing. Because diameter is important to pass through the firewall this hose has no fire sleeve but the laced leather wrap should be re-installed.
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.
