I am currently changing my gauges to standard VDO separate gauges
The oil temp sender was fitted.we decided to remove the pump to inspect the drive pins(some had roll pins?)we discovered the sender was longer and restricting the oil gallery!
The sender is now spaced back,we have a lot of 912's flying with different senders,I believe there will be a mass inspection here in the next few weeks
One aircraft with the same sender has had for the last 750hrs always had strange oil pressure significantly higher when warm.
Just a heads up
When changing what rotax recommends be careful!
