Got in about 20 minutes at Roebling then heard serious knocking from the engine...limped into paddock & shut it down. Towed it home (950 miles round trip for 20 minutes on track (IMG:style_emoticons/default/barf.gif) ) and dopped the engine. Couldn't turn the crank by hand on the fan. So, split the cases. Here's what greeted me as I opened it up--one ear of the windage tray had failed and slid over and was caught under the cam. Check the pics--you can see where the cam was striking the sheet metal piece....nice and shiny there.
It's a "CB" bus case.....anyone seen this before? Anyone with a replacement tray?? Now the plot thickens...see the pics of the crank....think it'll buff out? No wonder it lost power.... (IMG:style_emoticons/default/headbang.gif) Attached image(s) |

who did your crank?
i would have them take a look...... or may be another engine builder. for the crank to break there, there had to be some thing really wrong with the crank before machining or with what they did while maching it! |
