xair1159 Posted June 20, 2011 Posted June 20, 2011 Anyone heard of a new mod to the oil pump to reduce pressure pulsing? I am aware of the one from a few years ago which re-shaped the inlet and outlet ports. Nick
old man emu Posted June 21, 2011 Posted June 21, 2011 NOooooooooooooo!Not another engine mod for Jabirus:crying:
xair1159 Posted June 21, 2011 Author Posted June 21, 2011 Perhaps it's just an ugly rumour started by Rotax fans? Mutterings about it over here, thought those closer to the factory might have some facts.
jetjr Posted June 21, 2011 Posted June 21, 2011 Only one Im aware of was a long time ago in 6 cyl, where oil pump was cavitating. Nothing new. Some have tried moving oil pressure sender to other port measuring pressure AFTER the engine and this has less pulsing and longer sender life
Jaba-who Posted June 23, 2011 Posted June 23, 2011 I think it must be a left over from years ago. Haven't heard anything about a recent one.
