MochetVelo Posted March 25, 2010 Share Posted March 25, 2010 I just pulled the flywheel off my 1921 Peugeot 161 engine and discovered that it has no rear seal for the crankshaft. Instead, it is a "close fit" with a screw thread cut into the end of the shaft which (I hope) draws the oil back into the engine. Is this a common feature on cars of this vintage?Phil Link to comment Share on other sites More sharing options...
Guest cben09 Posted March 27, 2010 Share Posted March 27, 2010 I have seen this on crank and transmission shafts,,on both cars and motorcycle,,Vincent used this on crankshaft to keep engine oil separated from chaincase,, I'd have to think on the cars,,but I have seen it and they seem to work as long as the bearing is not worn out,,OR,,too much backpressure in crankcase,,Hope this helps,,,Ben Link to comment Share on other sites More sharing options...
Restorer32 Posted March 31, 2010 Share Posted March 31, 2010 Very common on pre 1930's vehicles. Oil will run out if you have the car on a steep enough slope, like loading it into a trailer with short ramps Link to comment Share on other sites More sharing options...
MochetVelo Posted April 1, 2010 Author Share Posted April 1, 2010 It also has a weep hole on the bottom. I suppose this directs the oil down to the ground rather than flinging off the flywheel.Phil Link to comment Share on other sites More sharing options...
