IO 550 pre lube pump

[Mr. Breeze]

Is there an STC for installing a pre lube pump on an IO 550. ( I have an M20J Missile )

They were the rage in the 70’s for cars because everyone believed that most wear occurs at start up and pre-lubing will prevent that wear, ergo your cars engine will last forever if pre-lubed.

However that didn’t turn out to be the case as cars and trucks that were pre-lubed didn’t last longer. If they would wouldn’t wouldn’t John Deere and other Uber expensive motors all have pre-lubers from the factory?

Back in the day there were a few Radial aircraft engines that did have to be pre-lubed, if they weren’t the one main bearing would be wiped out, they had to have an oil film prior to being started. One assumes this is maybe where the idea of pre-lubing making an engine last longer comes from.

Some will say those radials were pre-lubed for the cam, but it was the main bearing.

If you overhaul an R-1340, you MUST pre-oil prior to first start or it will wipe the bearing, even if you used lots of assembly lube, by wipe I mean the bearing will spin and you will soon get LOTS of metal in the suction screens.

Now if you could get a Lycoming cam dripping oil prior to start, then that would likely be a very good thing, but I don’t think a pre-luber will?

There are methods of pumping oil through the system if the plane has been sitting an extra long time…

There are methods of starting an engine in a hardware friendly manner… (things to avoid)

Welcome aboard Mr. B!

Why do you want to add a heavy system that is infrequently used?

PP thoughts only, not a mechanic…

Best regards,

Thank you for the link. 
No issue just preventative maintenance.

Cool story. Thanks.
