Pictures from Dave at Shasta Cascade R. P. S.

All the copper oil lines were removed from the LeRoi sometime in the distant past. There were at least 6 fittings on the crankcase and I didnt know what they attached to. I knew there were a few Whitcombs in museums around the country but I didnt know which ones still had the LeRoi RX1S 6 cylinder engine in them. I put some pictures of our engine on the Yahoo group 'Rail critters and asked for information about the engine. Dave Jungkeit answered right away and voluteered to take pictures of the engine at the Shasta Cascade Rail Preservation Society in California. Dave sent pictures which were a great help to me. I uploaded them to my Picasa album 'Shasta Cascade'. To get there click on the picture in the slide show near the top of this page. Thanks Dave.

Crankshaft Journals

When we removed the front block and 2 stuck pistons, I looked inside the crankcase and saw a shiny surface. I thought 'Oh this is good' but it turns out that what I saw was the back side of the insert bearing. It was siezed and stuck to the crankshaft. The bearing side was black and motled. I worried about the main bearings but after all the stuck cylinders were removed the crankshaft turned. I used a 4.5 inch angle grinder with a wire wheel to clean up the hardened journal surfaces. Some journals were discolored but they cleaned up and look like they will work. Where the connecting rod bolted to the journal there are 2 small lines etched in each journal. I believe from acid in the oil. I felt it with my fingers and it felt rough. I used a ball grinding stone on a cordless drill and polished the rough spots. My friend Bob told me that he had sucessfully rebuilt John Deere tractors with etch lines in the journals.
