David,
I just ordered the Aurora Diesel 6500 wt.
Don't know if it will have stem seals but if not.....can the ones you speak of be ADDED. I know it is not easy when the head is mounted but it can be done.
Thanks
Boeing, yes the Viton seals can be easily installed, but it is easier to yank the head to do it - the head gasket is solid copper, so it can usually be re-used without any problems and I have previously also re-used low hour exhaust and air intake gaskets without any issues.
A few more tips-
1. If your engine is not fitted with an hour meter, fit one - they are cheap and easy to fit and provide good insurance to facilitate regular servicing and maximise engine life. I bought a quartz/mechanical unit for $10 delivered off ebay, which works fine and only needs to be connected to the 12v DC terminals. A better alternative is the Curtis 700 series, which can also be purchased off ebay for around $30 delivered - I have bought one of these to fit to my Honda 11kva generator.
2. If your Chinese generator unexpectedly turns itself off immediately after being started, check the oil pressure switch. The oil warning lamp is actually an LED and on my unit, one of the connections had come loose due to dodgy soldering at the factory, so I was getting a switch off, but no warning light to indicate the reason. The original oil pressure warning switch fitted to these engines is a very long and relatively expensive unit which does not stand up to vibration well. Rather than replace mine with a genuine unit from China which sells for around $25 plus postage, I converted mine to use an 8psi Echin conventional switch (suits early Chryslers). The conversion required installation of a Narva fused relay, so all up the cost was around $25 but I saved the cost of postage and now have a far more reliable unit that should the pressure switch fail on again, can be replaced for around $5 from any auto parts store. Tridon TPS033 is the equivalent to the Echin switch I used.
Anders, check the 12v output on your generator. The terminals inside the back of my brushed alternator (4 pin molex type connector) were pushed in, causing bad contact, which supplied unregulated dc to the battery charging/exciter circuit. This could result in your generator overheating/AVR problem. There was also an inline glass fuse in the lines out from the molex, which was embalmed with electrical tape and could not be spotted unless you knew it was there.
