Looking for data on stations, limits, etc for McCauley em7653.

Anything on the site here or any links anyone knows of?

thx

Just replaced 2 and 4 with new Superiors (0-300c) and at hour 3 of breakin we are finding dark oily stain aft of both exhaust, rather than the light tan we used to get. Both sides the same. No work at all done on right side. We usually run Phillips 20-50, running the same but 'M' type for breakin. C...

Helpful info Bruce - happy to hear advice on when a post break-in comp check for those new cylinders would be most useful. Certainly not intending to cause any grief for the guy. Just its my butt in the seat up there over bush and rock most of the time, and I'm eager to have thorough work done. I go...

I like this! Well done. You should set up an STC.

A happy landing. Went back and pulled the cowls (I'm getting very fast at this, all 30 screws) and found that all of the pushrod housing covers had eased off a bit loose during the breakin flights. Was able to get small ratchet way in to the back and retorque them all, two 40 minute flights now, and...

OK – here's the update: back to the airplane today with my engineer, here's what we found. One nut not installed on the cylinder stud of the number 4 intake stub. Looks like the exhaust got put back on and covered over the intake stubs before we double checked our work back there. Fixed that, checke...

Good directions. Thanks. Will a shopvac running on 'blow' accomplish the same pressure? Compressor, set to ?? psi? Should I tape off the main air inlet to carb air box?

When I was a kid I looked at light planes and figured the venturi was a horn to alert people. Now maybe it is honking after all. While it is hard to locate the sound, it doesn't seem to be coming from that side, but i'm going to check everything. Thanks for the advice. BTW, the C172 forum pretty con...

Thanks - I'm going to check the oil for peace of mind. My AME is puzzled, wants to pull generator to check bearings. I guess these generators are prone to bad seal, looks like about a pound of some kind of goop around the gen base. I'm not eager to get into fishing expeditions like pulling periphera...

Engine turns over smooth by hand, no grind. Have not checked oil screens - just one flight of just under an hour.

Looking for your collected wisdom – have just installed two new millennium cylinders on 0–300 C, on break-in flight everything good, temps, pressure, power – but once on the ground an odd whining or squealing could be heard. Like you might hear if a belt on a pulley were running badly – but there ar...
