Shadrach Posted June 30 Report Share Posted June 30 I’m sure there’s an IPC available in the download section. here’s a stack from a 64 model. Not sure if it’s the same. Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted June 30 Report Share Posted June 30 Just take it to a welder and have them weld it back together. 1 Quote Link to comment Share on other sites More sharing options...

RH front, cylinder 2 - 1974 m20e io-360-a1a Download the parts catalog below - it covers your plane. Look at pages 186-188 One of the problems is that there isn't a "RH front, cylinder 2". The only way Cylinder 2 can be on the Right side is by looking at it standing in front of the plane looking towards the propeller. Cylinder 2 is on the Pilots Left side when viewed from the cockpit. However, your picture shows the alternator in the background of the cylinder with the exhaust stack removed, so I think you mean RH Front Cylinder 1. The stack for Cylinder 1 also has the more gentle curve which seems to match your stack. The stack for Cylinder 2 has a tighter radius. I think that you are looking for 630053-511. If you can't get it welded as @N201MKTurbo suggests, or if it is too corroded then it is easy to come by either salvage or new. I may be misunderstanding your description but I am sure you can work it out from here. Good luck. Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted June 30 Report Share Posted June 30 The picture above of the cylinder with the failed exhaust is cylinder #1. It shows the alternator behind it. 1 Quote Link to comment Share on other sites More sharing options...
N201MKTurbo Posted June 30 Report Share Posted June 30 How long has it been since your last inspection? That crack didn’t make it all the way around that pipe in a day. 2 Quote Link to comment Share on other sites More sharing options...

There comes a point where the metallurgy is so brittle that replacement of the complete system is warranted. If this system is original from 1974, you could be reaching that decision point.

McMooney Posted June 30 Author Report Share Posted June 30 exhaust is pretty new, despite how the picture looks, the pipes are not corroded or worn. that's not really rust on the pipes. thinking maybe the crack had been there awhile and my last landing/planting was the last straw 8) Quote Link to comment Share on other sites More sharing options...
McMooney Posted July 1 Author Report Share Posted July 1 Fingers crossed, I may not be grounded for the 4th after all, the wonderful people at Planeexhaust.net were able to fabricate a new riser in like an hour, should be here tomorrow. 2 Quote Link to comment Share on other sites More sharing options...
