slowflyin Posted December 16, 2014 Report Posted December 16, 2014 Quick question- IO360 pushrod tube retaining spring. One or Two per shroud. I've seen both and someone suggested there was a SB from Lycoming but I can't find it. thanks
MB65E Posted December 16, 2014 Report Posted December 16, 2014 Good Question! I think I used 2 on each. I want to say the gasket/overhaul kit I think has enough for two on each tube. I don't think 1 has enough spring pressure to stay put. If your putting it back together today and need an answer, 2 can't hurt... -Matt
Guest Posted December 17, 2014 Report Posted December 17, 2014 Two springs per shroud tube is normal. Clarence
N201MKTurbo Posted December 17, 2014 Report Posted December 17, 2014 I always did two, but it is so hard to get them in place and they chew up the tubes, the last time I put it together I just did one and it went together so much easier. I haven't had any leaks sense I did one.
slowflyin Posted December 17, 2014 Author Report Posted December 17, 2014 Thanks for the feedback. I did two where the pressure seemed reasonable but on two shrouds I backed off to one. Hoping for zero leaks. Thanks again.
N601RX Posted December 17, 2014 Report Posted December 17, 2014 Lycoming also has 2 different styles of pushrod tubes for the angle valve engine. The new style is formed from a single piece of aluminum including the ears that the spring plates push against. the older style had the ears welded on and sometimes crack or break off.
