theakerstwo Posted November 13, 2010 Share Posted November 13, 2010 hey guys on my b model the front seal of the engine cam went and its leaking oil pretty bad i was wondering if anyone knows where i can get oneA early 673 used a felt dust wiper that looked as a seal but had a oil deflector on the inside of the cover. I think the later crank seal if that is what your talking about but i think it was a direct replacement for the felt.If you can find a seal at the dealer i would pull seal and take to a store who seels seals.I dont think you will have a problem. We have a few stores here who seel brgs and seals and you may have to give them the meaurements.

Mike Posted November 13, 2010 Share Posted November 13, 2010 Hi Jocko, As Glenn has indicated it would be to your advantage to pull the gasket or seal and take it with you to a gasket, rubber company. They can at your request make or match your size seal diameter and thickness. mike Quote Link to comment https://www.bigmacktrucks.com/topic/16488-mack-673-engine/#findComment-66773 Share on other sites More sharing options...

Jocko Posted November 23, 2010 Author Share Posted November 23, 2010 false alarm after all it wasnt the front seal,after i pulled the radiator out i started the truck and noticed that there was only a oil line leaking on to the pulley, i changed the hose and the truck is good as new Quote Link to comment https://www.bigmacktrucks.com/topic/16488-mack-673-engine/#findComment-67227 Share on other sites More sharing options...
