CAT 3046

Why are these engines so hard to find?


Often called the Unicorn Engine, the CAT 3046 diesel engine can cause many people lots of frustration when trying to replace it. Cores are almost impossible to come by, and if you do happen to find one it is in bad shape. So what is a person to do who is stuck with this engine? Figure out a costly conversion? Risk a good running take out and pray that it is better than yours?

No. Diesel Nation has a solution. Our expert mechanics have spent the last few months finding vendors for parts, ensuring our machines are ready and all the staff is trained. We are excited to announce that we are now offering remanfacture and returns on the CAT 3046!

What is a reman and return, or R&R?

First things first, we need to know what is going on with your engine. Is there a hole in the block? Does the crank turn 360 degrees in either direction? Even if your engine has a few issues give us a call and let us know. We have lots of experts who know work arounds for many commons engine issues.

Once we have a good idea of what is going on with your engine we will arrange for our shippers to pick it up and send it to us. That is when the real work begins.

We break your engine down to the block and rebuild it back up to a zero mile engine using aftermarket, OEM or mahle clevite or similar parts. This process only takes us about 10-15 business days.

Once we are all done we ship the engine back to you. As always we ship insured so you can rest easy knowing your engine is safely on its way back.
