Attached are pics of the reproduction intake manifold for the big caterpillar twenty. This was the weakest link in the design of the machine as most of the original manifolds are cracked and destroyed. Catman from the UK reproduced this manifold to specs even better than the original caterpillar specs. The workmanship is awesome and the manifold is shipped ready to be installed. He also made other cat twenty manifold parts too and intends to make others for his friends. Even the shipping packaging for the manifold was a work of art and I wish I had photos to share of that as it had a long journey across the pond.
Because of Catman and his ability to reproduce and make this part and generously share this, my brother and I will be able to restore the first caterpillar we ever bought at age 15, which currently has a homemade intake manifold.
