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) |

Was the bolt that holds the tray loose or missing? Second was the tray possibly not slotted correctly in the case? If one side was out it would be bent up in to the cam. Did the tray have the seals on it or did they stay in the case.

Did the tray have the seals on it or did they stay in the case. The cross bolt was in place and tight....it was slotted correctly with the seals glued to it with a dab of weatherstrip adhesive at the ends--you can see a bit of it in the photo. Seals still in place in the case slots--looks like fatigue failure right at the ends of the louvers stamped into the tray ear. |
