Lister Generator series 2... the new project

The Lister "new" Generator Project

So I wanted to build another Gen set. A smaller unit that world be transportable, burn less fuel and be much prettier. My fiends and I had agreed on another engine order from India. This order would come from Geco Trading Corp in Mumbai. These engines were again unknown so we went with the cheapest prices figuring we might loose all our money etc. The engines were built and shipped and took the usual 8 weeks to arrive followed by paying off corrupt customs officials, greedy warehouse workers and so on until we finally took possession of our new property. One thing about corruption and influence peddling in America, it may be wrong, but at least these American are reasonable and enthusiastic when you cough up the dough.

We quickly disassembled the crates to inspect our mystery engines and were pleased to find the quality was adequate, all the arts were there and undamaged. It was agreed the engines should be disassembled to inspect them and blue-print the parts as all of us wanted to build an engine that would last. It was a good thing we did as you'll see in the following pages.

Here is a photo of the 6/1 Engine sent to us by the factory prior to be crated up and shipped.



Above are the three engines freshly removed from the crates. We ordered spares in the wooden crates in the foreground. We bought everything we thought we'd ever need including spare cylinder heads ($25) and cams, pistons, rings, liners etc. About $100 worth which is a lot of spare parts!



Here the heads and cylinders are removed showing the massive pistons. It took about 30 minutes to get this far. Next comes the flywheels and crankshaft removal. We had to build a GIB key puller to pull the stubborn GIB keys to allow removal of the flywheels. Each flywheel weighs about 200 lbs. The crankshaft journals were scratched up a bit due to poor quality construction and using a mixture of stink-oil and sand during the initial engine run at the factory. This is pretty common in India and the engines' must be cleaned, the crankshaft polished and new bearings installed as a minimum with each new engine delivered. Here is a
video of the crankshaft being polished.



Here is a  photo of yours truly leaning on the crane, with another friend standing and the infamous CUJET working on his new 20/2  engine. Photos of these engines being prepped is coming soon. You can see the 6/1 in the background that is now the star of these web pages and following video.



Opps! look at this rust. Water got in here during shipment. The rust was thin, but the factory sent us a new piston and cylinder assembly without any argument.

AYYYEEE! That thin white line above the bronze bushing is daylight! They really botched up this connecting rod. A gentle push and the bushing fell right out. The factory sent us a new rod as well. Funny thing... We weighed the rods from the three engines and while they were all the same part number, they all weighed the same...HAH!...Just joking, some weighed 7 pounds and others weighed as much as NINE POUNDS! How's that for balancing!

After all this work, here is this fantastic machine in its' completed form....
