Ah no, wait, only a dot missing: http://www.steyr-motors.com/applications/a107.htm [*] finally I have the automotive spec's complete!....always had inconsistent data because the marine engines were different, and the automotive engines were application-dependant (see also that second list of application links, they all differ a bit in hp/torque spec's) -- 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: "dennis" Date: Tue, 6 Dec 2005 07:00:43 -0700 Subject: FW: [pinzgauer] Steyr diesels, new applications Reply-To: pinzgauer@yahoogroups.com Willem Hello your comment on the GM 6.5 is not without foundation. We still specialize in fixing this engine which incidentally started off life as a "big Block Gasoline (petrol) engine. Originally opened up to 5.9 litre and made a CI engine with a Standyne mechanical rotary injection pump to fuel it, the thing was a disaster in Cadillacs/Oldsmobile car and so on in the 70's. GMC "reinvented" it with a 6.2 derivative for light trucks and it wasn't too bad in its normally aspirated form. Still suffering from fueling troubles, the company muddled it through until they developed the 6.5 with turbocharging. Most of the HUMWVV's had the 6.2. The only real difference from the "civi" application was a non controlled glow plug system, injection, and fuel filtration. The civi turbo 6.5 can be found in some HUMWVV's with a mechanical Stanadyne injection pump, overall it wasn't a bad engine for what it was, but suffered from overheating (steam pocketing) in the heads in adverse conditions (Like Iraq I can imagine )causing severe head cracking and seizure of the rear cylinders. After 1993 the engine was made an OBD2 conforming unit with electronically controlled Stanadyne pump with drive by wire control. The rear cylinders were given an extra 001" to 0015" clearance to reduce the piston seizure problem and the pistons were coated in Teflon. By the year 2000 the engine had got a 25GPM water pump and two separate thermostats to control coolant flow plus some smaller mods to enhance durability. Overall the engine was on its deathbed by the year 2000 and many of us wondered why GM labored so long with it when there were other proprietary engines incl Isuzu which of course ultimately found its way into the GMC range of trucks as the 6.6. Having worked for 6 years in Iraq I can imagine the engine to be nothing short of an unmitigated disaster in the heat. The power pack in a HUMWVV is a pig to get at and I can imagine working on the engine in semi combat conditions would not fill me with too much enthusiasm! The unit in the US earned itself a terrible reputation amongst US operators and needs lots of TLC from someone who can baby it during service intervals. For a short while I had a Suburban powered by this engine and I quite liked it! Having stated all that I have a fond appreciation of the engine since most manufacturers who historically have converted petrol engines to CI (diesel) operation have experienced disastrous results. The GMC unit faired slightly better. There is a full power unit available for marine use that can really knock your socks off and as long as you don't have to worry about emissions it can turn out some respectable horsepower (for an old gasoline engine!)
