Is it also being powered in a 'redundant' context? As in: if one oilpump locks up, would the other still keep the engine lubricated, at least in the non-demanding horizontal plane? Btw, would/could a dry-sump design also be made redundant, more easily? It seems to be favored in high-G applications, where also a very low engine mounting is wanted, but I can't see why this couldn't be used for offroad either, steep inclines or off-camber. http://www.reference.com/browse/wiki/Pinzgauer_High_Mobility_All- Terrain_Vehicle xxxxxxxxx The pinzgauer was also designed to be reliable and easy to fix. That is why it comes with an air-cooled carbureted engine. Air-cooled carbureted engines are still in use in many small aircraft due to their reliability. This is partially due to the fact that air-cooled engines have been around longer, and partially due to the fact that they are simpler and have fewer parts. The engine in the pinzgauer is a special engine designed specially for it. It has more than one oil pump so that the engine will not get starved of oil no matter the orientation. xxxxxxxxxxxxx -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] To: pinzgauer@yahoogroups.com From: "Jim LaGuardia" Date: Sat, 22 Oct 2005 08:42:27 -0000 Subject: [pinzgauer] Re: dual oil pump Reply-To: pinzgauer@yahoogroups.com One pump scavenges oil and returns it to the reservior(oil pan), the other half is the lubrication pump. Both pumps are driven by the same shaft. Just look at the parts manual for a better understanding of how it works. Cheers, Jim LaGuardia
