Talk:Lycoming O-360

message: Can somebody who has that information (and reliable sources) please add something about the valvetrain? Some rods in the images look like they might be pushrods, but when that is true, it could still be either a flathead engine or an overhead valve engine. What is it?--ospalh (talk) 20:19, 21 August 2010 (UTC)
replies: text: A technical description of the engine certainly needs adding. I can describe the valve system for you though, what you can see are the aluminium outer pushrod tubes. A central camshaft operates two steel pushrods per cylinder, one exhaust and one inlet. Between the pushrod and the camshaft is a follower and a hydraulic cylinder (fills with engine oil which also runs through the hollow pushrods out to the valve rockers (it's OHV). On initial set up different length pushrods can be selected to obtain a specified valve clearance, the hyd cylinder fills with oil and takes up this clearance and maintains it in service. Hope that helps a bit. Cheers Nimbus (Cumulus nimbus floats by) 21:49, 21 August 2010 (UTC)

message: I do not think the "H" versions (HIO-360, HO-360) are vertically mounted.  The HIO-360 is used in the Enstrom helicopter, but is horizontally mounted with a belt driven transmission.  There is another model IVO-360-A1A which is a vertical variant that is used in Brantly helicopters. — Preceding unsigned comment added by Gadoid (talk • contribs) 
:The ref seems to support what you are saying here, "These engines are approved for horizontal helicopter applications and operation", so I will fix that! Thanks for pointing that out. - Ahunt (talk) 01:02, 23 August 2014 (UTC)
replies: text: I believe the other "H" variants are also horizontal.  The "IVO" model should also be added to the list.  Information on this variant can be found here.  — Preceding unsigned comment added by Gadoid (talk • contribs) 01:50, 28 August 2014 (UTC)

replies: text: The shabby photo is mine, looking at the other images on Commons there isn't much choice. I took another image that day (right) that I took from a higher angle, I've edited it just now as it was quite underexposed and uploaded it. Feel free to change it though I'm not convinced it is any better. Nimbus (Cumulus nimbus floats by) 15:34, 20 August 2022 (UTC)
