XUD Engine Build Problems

Post by evilally » 28 Jul 2014, 22:57

I've just finished building up an XUD. I started with a block with a crank already installed (didn't disturb this as it was low mileage). Pistons and rings all went back into the same cylinders they came out of (everything was cleaned ultra sonically). New OE con rod shells were fitted. Everything lubed up with new engine oil when assembled and torqued correctly. It all seems to turn over ok by hand using a wrench on the crank pulley, a bit tight when there's compression but otherwise seems fine. I've hooked up the starter with jump leads to a known good battery. When I fire the starter, it turns slowly 2 or 3 times then stops. The jump leads get very hot. I thought it might be a duff starter, so swapped it out with one off my 406 but with the same result. I've cleaned up the areas where the jump leads are connecting to.

Any ideas? If someone else told me this I'd say bad starter or bad contact somewhere. I'm going to borrow another set of leads to try in the hope I don't have to pull it all to bits again :evil:

when it comes to a stop have you then tried turning it further with a wrench on the crank pulley,
as this could rule out starter/leads or battery

Thanks for the suggestion Malcolm, today I swapped out the jump lead on the negative terminal for the original earth strap from the car body, started nice and easy, video to follow :-D
