It's a 98 registered Mk1 ( must have been sitting in a dealers for some time ) and had a genuine 16800 miles on it last Aug. it's up to 21k now. Monday morning I thought I'm changeing the belt, two and a half hours later I still can't get the crankshaft nut undone 
and the Autodata book says it's a 2 1/2 hour job. I tried the old breaker bar and scaffold bar over it wedged on the ground and hit the starter, just got clunk clunk. Rubber plug out of the sump and a bar in the drive plate, then strapped the bar to the suspension ,two foot Snap On breaker bar on the crank nut and 15 stone + of me holding the roll bar and both feet on the breaker bar . Decided it was time for a break, got in the Fiesta and drove to a friends garage, he couldn't suggest anything, so I drove up to Lexus Southend. I sort of know the workshop foreman there, told him my sorry tale and he loaned me "the Lexus tool" . It's a tube that bolts to the crank pully with two 8 mm bolts ( I couldn't see the bolt holes as they are recessed ) you then fit a holding bar to it with a pin. The bar sits on the chassis rail under the air filter box, you then put a deep reach 22mm socket through it onto the crank bolt. Same again Snap on breaker bar both feet, can't move it, jacked the car up even higher ( the exhaust tips are now almost on the ground ) put a scaffold tube over the breaker bar and BANG. I didn't want to look, I was expecting broken oil cooler pipes or a hole in the rad. Took the socket out and undid the bolt with my fingers . The rest of the job was easy, after I got the pully off. I took some pictures of the tool and all the relevant dimensions, but on reflection you don't need anything so complex as the official tool. Either a piece of thick 3" angle iron or probably better a piece of flat metal about 75mm x 10 mm about 600mm long. 2 8mm clearance holes drilled in it at 65 mm centres and a large hole to get a 22mm socket through centrally between them. I'm going to make one, because once I have it I will never ever need it again
