Guest dnoz Posted March 1, 2011 Share Posted March 1, 2011 I have a 1913 Buick model 25. The crankshaft comes out of the front of the engine passing through a gear box. The gearbox powers a side shaft for the water pump and magneto. In front of the gearbox there is a fan pulley then the male end for the hand crank to engage. As it exits the front of the gearbox there is an oil seal which expands with compression. I need to replace the seal. Any recommendations on what the seal should be - leather, rubber or packing rope? Also, where to get a suitable replacement or must I fabricate one. Any recommendations please! Thanks in advance.David<!-- google_ad_section_end --> Link to comment Share on other sites More sharing options...

Dandy Dave Posted March 2, 2011 Share Posted March 2, 2011 It has been a few years, but I think my 1915 C-36 used a Felt seal originally. The front timing case has it's own fill plug and it is recommended to use gear oil in it. I bet your car is very similar. Dandy Dave! Link to comment Share on other sites More sharing options...
Larry Schramm Posted March 3, 2011 Share Posted March 3, 2011 I agree with Dave. The seal in the timing cover was/ is felt. It fits into a recess that has an opening on the bottom side of the recess. The oil is "caught" by the felt and then drains back into the crankcase. Link to comment Share on other sites More sharing options...
Guest dnoz Posted March 6, 2011 Share Posted March 6, 2011 Thank you. I suspect you are correct and it makes sense. I used gear oil in the timing case through the plugged opening on top. I plan to use graphite rope/packing in place of the felt. Any thought on where to get felt that would work? It appears the flange, when in place, compresses whatever is inside and thus graphite rope packing seemed acceptable. Link to comment Share on other sites More sharing options...
Larry Schramm Posted March 6, 2011 Share Posted March 6, 2011 You might laugh, but the jute backing for carpet seems to work well. Just cut out a piece as large as the outside diameter of the opening and then the center hole a little smaller than the crankshaft and you are done. I a have also glued some felt together to get a piece thick enough for the opening. Link to comment Share on other sites More sharing options...
Guest dnoz Posted March 6, 2011 Share Posted March 6, 2011 Thanks Larry. If the rope doesn't work I'll try this. Link to comment Share on other sites More sharing options...
21raceabout Posted March 6, 2011 Share Posted March 6, 2011 McMaster-Carr's on line catalog has felt that can be used for oil seals. Link to comment Share on other sites More sharing options...
21raceabout Posted March 6, 2011 Share Posted March 6, 2011 And don't forget to oil the new felt seals liberally upon reassembly, otherwise a dry seal will work like sand paper on your shaft. Link to comment Share on other sites More sharing options...
