pudestcon Posted February 24, 2010 Share Posted February 24, 2010 G'day, I'm looking for an exhaust manifold and pipe for a blue head 582 Rotax. This will be going on a T500 Thruster and right now I need to know what sender/thermocouple I need to purchase for the EGT gauge (VDO 'Cockpit' series gauges). So 2 questions.... 1) Where can I get an exhaust manifold and pipe - doesn't have to be new? 2) What type of sender/thermocouple do I need? Screw in (what thread) or clamp or what? Thanks guys Pud Link to comment Share on other sites More sharing options...
Guest terry Posted February 25, 2010 Share Posted February 25, 2010 Hi Pud, I suggest you have egt to both cylinders. Mine didn't but does now. I'd be interested to know what others think about this Link to comment Share on other sites More sharing options...
pudestcon Posted February 25, 2010 Author Share Posted February 25, 2010 So a dual egt gauge with senders from each cylinder exhaust manifold, yeh Terry? Pud Link to comment Share on other sites More sharing options...
facthunter Posted February 25, 2010 Share Posted February 25, 2010 582 exhausts. Not expert here but I have fiddled with a few. The EGT seems to be very unreliable in service . I would stick to standard positioning for the probe. It has been sorted out and will give you different readings with different positions. You could operate with one probe and swap it over to get each cylinder temps. Run two if your pocket can stand it. Nev Link to comment Share on other sites More sharing options...
icebob Posted February 25, 2010 Share Posted February 25, 2010 Hi, Try www.lightflying.com.au, i got mine from them for a 582 blue top. look under Probes, Senders & AAccessories. Delivery was 2 working days. Bob. Link to comment Share on other sites More sharing options...
Methusala Posted February 25, 2010 Share Posted February 25, 2010 G'day all, I got an EIS from Grand Rapids Technologies. It cost me $A750 delivered and monitors 2x CHT, 2x EGT, Engine revs, coolant temp. system voltage, engine hrs, outside air temp and for $150 extra altitude and vertical speed. It has limits that can be set both upper and lower and comes with all probes and wiring. The weight is around 600g. performs perfectly and takes up very little space.

pudestcon Posted February 25, 2010 Author Share Posted February 25, 2010 Well a lot of useful information and advice here:big_grin: Thank you very much fellas; especially icebob for the link which has just the sender I want. Turns out for a reasonable price too. Now what about question 1.......... Where to get the exhaust manifold and pipe? Cheers, Pud Link to comment Share on other sites More sharing options...
icebob Posted February 25, 2010 Share Posted February 25, 2010 Hi, sorry forgot to include about question one, I got mine from Burt Floods, rang them and told them what i wanted with slight modification and got the ceramic coating too both at a competitive price.

Guest terry Posted February 27, 2010 Share Posted February 27, 2010 yes Pud egt on both cylinders. If I'd had them to start with I would'nt be rebuilding my T500 now and my flying interrupted for two years. Link to comment Share on other sites More sharing options...
pudestcon Posted March 1, 2010 Author Share Posted March 1, 2010 I emailed Wal at Bert Flood and got an almost instant reply. The cost will be $775 plus tax and freight - didn't ask about ceramic coating. I went for a fossic in a shed today after being told there was an exhaust andf manifold somewhere in there. I duly found it and it is now in my possession for a rust removal and rejuvenating coat of paint. Is there a rust preventative type primer suitable for exhausts? Or do you just paint it with the heat resistant paint suitable for exhausts? Pud Link to comment Share on other sites More sharing options...

icebob Posted March 2, 2010 Share Posted March 2, 2010 Hi Pud, There are some expencive paints out there but on my old Rotax I just used a wire brush, a good wipe with a cloth soaked in metho and heat resistant paint for exhausts from an auto shop. Every so often just hit it with the wire brushand a wipe over with metho(you can if you want drink what is left in the bottle,ha,ha) again and re applied more paint. Bob.

pudestcon Posted March 8, 2010 Author Share Posted March 8, 2010 ;););););) You should see me in real life:faint: I've noticed on the exhaust and manifold that the spring lugs have worn through somewhat. Do you suggest I weld (oxy/acetylene mild steel) a repair on each lug to restore the full thickness of the lug? Pud Link to comment Share on other sites More sharing options...
icebob Posted March 9, 2010 Share Posted March 9, 2010 Hi Pud, Yes you can BUT take care to relieve stress from welding and check very regularly around the base of the lug for cracks and splits(I check every 20 hours or so). nothing worse than the lug giving way while in flight, you loose the spring too,bugger:sad:.

pudestcon Posted March 15, 2010 Author Share Posted March 15, 2010 Sorry for the late response icebob, I was just reviewing this thread and saw I didn't respond to your last post. Thanks for the advice on the welding. In the past I have done a bit of oxy acetylene mild steel welding but don't have the equipment any more so I'll just get someone to do it for me. I've cleaned up the exhaust now and its about ready for the primer and paint. I now need 2 support mounts like the attachment here - hope they are a common item.

icebob Posted March 16, 2010 Share Posted March 16, 2010 Hi Pud, Yes these are common parts, my last lot I think I got from Supercheap auto or one of those, there are two types one with metric thread and one with imperial thread, took a nut with me to make sure. Thay lasted two years for me at around $6 each that was cheap. Bob. Link to comment Share on other sites More sharing options...

pudestcon Posted March 21, 2010 Author Share Posted March 21, 2010 The exhaust saga continues.... I found out during the week that the manifold I have for the 582 is actually off a 503 and only has 2 bolt holes on each fixing plate as opposed to requireing 4 bolt holes on the 582 - the hole position is different too as is the actual size of the base plate. See these photos and you'll see what I mean. I think I'd better give Wal at Bert Flood a call:idea: Pud Link to comment Share on other sites More sharing options...
icebob Posted March 21, 2010 Share Posted March 21, 2010 Holy....S.... Batman, not good what about the rest of the motor any interchange of parts? The aircraft repairs done in the past to me may need checking for not to standard works, an uneasy feeling here. now you may find with a new manifold the mounts from above are located differently too, what about the springs are they good ones(resting length and thickness)?

Bob. Thanks for your exclamation Bob:big_grin: Don't worry, I am fully aware of the potential issues but am confident all will be correct once we get to test flying day!!! A new manifold and springs will be purchased to solve the current issue. Cheers, Pud Link to comment Share on other sites More sharing options...
