bran1har Posted June 25, 2018 Share Posted June 25, 2018 (edited) Im wondering if anyone has any information on this. Ive had a hard time finding the hub cap that I need for the front axle on my 1979 Mack U model single axle dump. I just bought it, going through everything. I cant for the life of me find a part number on the cap itself or find the right one anywhere on the internet. I took a couple measurements with tape measure from the outside, never actually unbolted it, bolt circle: 6'', 6 bolts, 5/16 hardware, overall diameter of whole cap is 6 1/2'', id of flange: 4'', overall height of whole thing about 1 3/4''. I found this one (https://www.finditparts.com/products/454233/stemco-340-4059) seemed to be closest, if the only 6'' bolt circle one anywhere on the internet, but the flange measurements seemed a bit different. Anyone got any insight, greatly appreciated. Thank you. Edited June 25, 2018 by bran1har forgot something Quote Link to comment Share on other sites More sharing options...
j hancock Posted June 25, 2018 Share Posted June 25, 2018 You could check the specs on Stemco 343-4176. It is slightly different. New design? Superseded part design over the years? Looks like you just need a window kit. Stemco makes replacement parts for 2.75" and 3.5" windows. Check out the Stemco Wheel End Catalog pdf. on the computer/google search. Page 56. 2 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
Ezrider Posted August 10, 2018 Share Posted August 10, 2018 as i read the first part i was thinking the same thing on the window kit. probably a lot easier Quote Link to comment Share on other sites More sharing options...
kscarbel2 Posted August 10, 2018 Share Posted August 10, 2018 I believe you'll find that you have a Stemco 343-4025. 1 Quote Link to comment Share on other sites More sharing options...

Ezrider Posted August 14, 2018 Share Posted August 14, 2018 hum didn't think of that. i have a couple different parts guys i normally take that kind of odd ball stuff too and they will pull out the paper parts books and normally find what i need.

Every once in a while though, you'll be able to get them out. I'll always try the screws before I pull the whole cap. If you do manage to get the screws out, add a healthy dose of anti-seize, and they will be easier to get out next time. Seems you have to change these quite often, as the plastic window gets brittle with age and cracks. 1 1 Quote Link to comment Share on other sites More sharing options...
