I am working on my friend's 763, getting out 80 yr old grease and just generally cleaning it up and lubing it. It has been sitting on his shelf for around 20 years. Unfortunately it has a cracked cab in the right rear but it does run well, now that it's been lubed with red and tacky. I was just wondering if there is anything special about this engine I should be aware of since it is pre war, around 1940-41 and I can't find much info on it. At some point someone put the wrong rear wheel on the rear axle of the rear truck. They should be open spokes like the drivers but one is a solid disc wheel and just a smidgen smaller in diameter than the spoked wheel. Also the front wheels on the rear truck may also be the wrong ones. Are they supposed to be pressed onto the axle shafts? Both of mine spin freely around the shaft and there is one washer and a washer with a scalloped edge! If anyone has any specific info on this engine let me know, I would appreciate it.
driveshaft with ball bearings sandwiched between two washers and axle blocks. Note the cylindrical looking piece at the bottom of picture, that was the solidified grease in the top of the gearbox. It looked like Fels Naphtha soap!
Chassis with weight(upper left) removed and gearbox open. Most grease has been removed. I did not pull wheels, I thought it might be too risky with this old an engine. All original wiring.
Crack on right side of cab
Crack looks much worse on this view.
Rear truck, you can just barely see the spokes on this wheel, the one on the other side is the solid disc wheel. Note the scalloped 'washer' on the left front wheel. I believe they were just put in as spacers.
Well thanks for looking, this is/was a rather famous engine like the pre war 700.
