Jholveck Posted November 30, 2019 Share Posted November 30, 2019 I need part numbers or parts for the spring pads and 1 cap. No idea of what springs I have. Big rear ends.

h67st Posted November 30, 2019 Share Posted November 30, 2019 I found the numbers for mine by getting the build sheet from the Mack Museum. Mine has the 34k suspension so it wouldn't work for you. You could also check Stengel Bros. http://www.stengelbros.com/ they have a lot of Mack springs and parts.

Rob Posted November 30, 2019 Share Posted November 30, 2019 Post up your numbers which are stamped into the rear rear axle housing on the right side looking from the back. With these the suspension can be identified and drilled down to corresponding parts you are inquiring about.

Jholveck Posted December 11, 2019 Author Share Posted December 11, 2019 Here is a couple of pictures of the other side. 1 good number of the cast iron cap. The others are aluminum Quote Link to comment https://www.bigmacktrucks.com/topic/59996-b73-camel-back-spring/#findComment-437793 Share on other sites More sharing options...
Rob Posted December 11, 2019 Share Posted December 11, 2019 The number I referenced will be hand stamped into the axle housing. Looks kinda like these: Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

JoeH Posted December 11, 2019 Share Posted December 11, 2019 Pictures showing the spring pack and the axle housing will do more to help people identify your parts than a close up of the elephant pads.

Rob Posted December 11, 2019 Share Posted December 11, 2019 (edited) Given you've mentioned aluminum caps and I've only seen those on 34K rated rear suspensions, look at this photo and see if what you are looking for is there. If you are looking for #9 in the diagram, there are three available; 5-7/8", 6-3/8", and 6-3/4" deep. These are called "insulator boxes" and I don't know if you'll find aluminum ones new.
