Does any one have part numbers for roller bearings and seals for 1/2 ton AD trucks? Hoping I can pick them up at NAPA or one of the bearing houses locally. Thanks. | | | | | Joined: Mar 2008 Posts: 1,775 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 1,775 | Napa probably can't help. They are one-offs made by MBS Bearing out of Japan. Most of the vendors out there have them availible, though. Try www.classictruck.com , they seem to have the best prices, I've found. Chev's of the 40's and Jim Carter probably have them too. | | | | | Joined: Dec 2004 Posts: 1,897 Shop Shark | | Shop Shark Joined: Dec 2004 Posts: 1,897 | They are no longer made by MBS. I believe the MBS bearings are superior to the chinese roller bearings. My 59 gmc 1/2 ton went through 2 complete sets of the chinese bearings. The bearings ended up destroying my spindles forcing me to find a new front axle.
Inner seal: National #6064
Inner bearing and race: MBS #909052R
Outer race: Timken #LM11919
Outer bearing: Timken #LM11949 | | | | | Joined: Nov 2011 Posts: 139 Shop Shark | | Shop Shark Joined: Nov 2011 Posts: 139 | Thanks for the info. Now to sort through the disc brake conversion options. Might as well do it all at one time. | | | | | Joined: Dec 2010 Posts: 291 Shop Shark | | Shop Shark Joined: Dec 2010 Posts: 291 | Imho I would install newer roller bearings with the disk brakes. Good luck on your parts Quest.
