Compressor Replacement Detroit 60

I'm pretty sure the 11.1 and 12.7 compressors are the same. What is the reason you need more CFM?

 

Yeah, I don't think there are a lot of good options out there. Keeping your dryer filter replaced will help, but I think that's about it.

 

You should be using a TF-550 Bendix model compressor; this is what is listed for a D60 of those years, all of them.

I think the 750 is a direct interchange and larger displacement.

This means that the head of the unit can be turned to accommodate the hoses and lines of your engine.

I don't think the 550 can be rotated because it is a two-cylinder compressor, but the 921, which is on the later engines, can be because it is a single-cylinder. SO I would assume that they are trying to get a replacement compressor unit and may not be right for the truck, the flange I think, will be the problem.
