SkepticalJohn Posted April 12, 2021 Report Posted April 12, 2021 (edited) If there's anyone out there who has completed an engine overhaul on a M20K 252 converted to a 305, I'd love to pick your brain for about 5 minutes. Or, if you know someone who's been down this road and you can put me in contact with that person, please PM me. Thanks! John Edited April 14, 2021 by SkepticalJohn More clearly sate the question...

SkepticalJohn Posted April 13, 2021 Author Report Posted April 13, 2021 Thanks, sir. I appreciate the offer for assistance, but my question regards the engine mount bushings between the TSIO520-NB and the mount - usually changed at overhaul. Quote
N201MKTurbo Posted April 13, 2021 Report Posted April 13, 2021 You might call Troy at TAC at KAVQ. He put a new engine in 231JV a few years ago. 1 Quote

If you are asking about the lord engine mounts for a Rocket... You should make that a bit clearer... We have many Rocket owners around here that are knowledgable about their ship without going through the OH process... Sure... They get changed at OH, and whenever the engine sags... What’s your question? I might know a few Rocket owners we could ask... or even prior Rocket owners... Or even a phone number and a website for Rocket Engineering... Don’t spare the key strokes... use as much detail as you can... PP thoughts only... Best regards, -a- 1 Quote
SkepticalJohn Posted April 14, 2021 Author Report Posted April 14, 2021 Okay, which Lord mounts are they? The originals are Barry, but those aren't available right now. My question is... Besides the original Barry mounts, which rubber engine mount bushings are being used in Rockets? 1 Quote
carusoam Posted April 14, 2021 Report Posted April 14, 2021 @aviatoreb, @FloridaMan, @M20Doc There are probably two dozen more Rocket owners... It would be cool if I had the memory skills to list the rest... If you want to update the title... there is an edit button for the person who wrote it... up at the top right corner next to the title... Best regards, -a- Quote

aviatoreb Posted April 14, 2021 Report Posted April 14, 2021 I'm sorry - I'm afraid I don't have much information to add - we changed mine out about 10 years ago when the plane was relatively new to me, but I cannot remember which ones we went with, and it all seems still fine now. Quote
carusoam Posted April 15, 2021 Report Posted April 15, 2021 @Rocket @Rocket 305 @Rocket_Driver @RocketAviator @rocketman I’m inviting a few Rocketeers to see what we know about engine mounts /rubber donuts for the Rocket’s engine... What do you have, where did you get them..? Best regards, -a- 1 1 Quote
SkepticalJohn Posted April 15, 2021 Author Report Posted April 15, 2021 If it'd help jog a memory, here's how the old ones looked... Quote

John Have you called Rocket Engineering? https://rocketengineering.com/contact-rocket-engineering/ They still provide some support Quote
SkepticalJohn Posted April 15, 2021 Author Report Posted April 15, 2021 I did, limited hours/availability. Moreover, I've had word from a source, who won't be named, that part number hasn't been produced in 10 years. So if anyone has that Barry mount on their shelf, it's old. I need to know what people are using instead of the pictured mount above. IE: field approval of Barry mount 94006-01 (or Lord or whatever mount you used)... 5 hours ago, LANCECASPER said: Have you called Rocket Engineering? https://rocketengineering.com/contact-rocket-engineering/ They still provide some support Quote

SkepticalJohn Posted April 15, 2021 Author Report Posted April 15, 2021 The engine mount (metal part) is just now in the final stages of rebuild. The vibration isolators/bushings are just rubber - nothing to rebuild. The ones I have are in good condition. However, I'd like to replace them with new ones while the aircraft is in 50 pieces vs waiting until they need attention and grounding the aircraft again just for bushings. Quote

SkepticalJohn Posted April 16, 2021 Author Report Posted April 16, 2021 4 hours ago, N201MKTurbo said: Have you called Berry? Yes, they were quite helpful. Parts are OEM, not PMA. For folks who don't know the difference, in layman's terms... PMA = the manufacturer can sell it to you, the end user. OEM = the manufacturer ONLY sells it to the (in this case) STC holder, STC holder sells it to you. In any fashion, the lead time on Barry creating the mounts once an order is placed by the STC holder is 120 working days (doesn't include weekends or holidays)(read... 6 months) 1 Quote
carusoam Posted April 16, 2021 Report Posted April 16, 2021 How Rocket specific are they? Since the Rocket engine came from a Cessna twin... Any hope of finding a match that way? Best regards, -a- 1 Quote
