Question:

question about a spicer heavy lift axle on a commercial truck?

I need to know how to identidy a spicer axle. I bought a truck that had a spicer lift axle installed about 6 years ago.I need to know the rated capacity of this axle in order to register the truck. When the axle was installed,they never filled out the I.D. sticker that goes in the door jam ( I have the incomplete sticker,it was in a folder with the maintnance records for the truck. ) And the spicer tag that was on the axle tube is rusted to the point that you cannot make out any of the numbers. I‘m at the point that if I cannot ID this axle so my mechanic can get me a heavy weight on the truck,I‘m going to have to remove the axle and drop to the lower weight class which will render the truck virtually useless for what I need it for. Can anyone help? Or does anyone know a Heavy truck inspection mechanic in the western PA. area who is not so tight laced????? And just for the record,I tried to contact Spicer and they were not much help. Thanks for any help. Rob in PA.

Answer:

You go with copper since it is the most ductile. Iron is much heavier and rust really bad. Brass would probably not be used because of the high cost.
Back when copper was relatively cheap, plumbers did use DWV copper for drains and vents. Installed correctly, it is the best material for drains, since it won't rust and corrode, like tubular brass, or harden and split, like PVC, or ABS pipes. If it was just installed, call the plumber, and demand he fix his installation. If you have any problems with him, look up the phone number for the state board of plumbing examiners, and report him. I assure you, they will help you get satisfaction. Good luck!
Copper is reddish in color. Brass is allot like copper but more yellowish in collar. Aluminum is a silver collar and lite weight. Lead is silver collar and heavy a magnet will not stick to those metals then you have steel and a magnet will stick to it. Car batteries at a scrap yard pays i think 5 bucks. You could just load it up and take all in at once but you make allot well a heck of allot more if you take your time and strip it all if you do that make sure you clean all the plastic and any steel off it and keep it all separate
Contact Spicer again and ask for their technical services department. This happens a lot and they have an excellent staff to help you ID the axle housing, bearings and axles themselves. They will then be able to give you a rated capacity of the complete assembly. You will also need to know the id of the differential pumpkin. The input pinion shaft has a specific input rating too that translates into maxium torque load capacity as well. When they rebuilt the rear end I hope they kept all the orginial rated parts in it. Other wise you will have to rebuild it all over again to the spec you want. Spicer techs can help you with that too.
