Yes, that is a Cummins part. The 4bt was developed by Case and Cummins. Your part was used on applications with a vertical exhaust system. Cummins part 3910992 is Case part J910992 which lists for $497.35. Wee bit of markup from the one you found for $50. LOL. Hagan Tractor Parts shows Case part A173623 replaces part J910992 or 3910992. They have used ones for $70 but the $50 is a better deal. When Case and Cummins ended their joint venture Case stated renumbering all their parts.
4bt vertical exhaust elbow? Case vs Cummins
Looking for a 4bt exhaust elbow for a Case 860 trencher. Case wants about $500 for p.n. A173623.
Found some on eBay for 180. Didn't know if this is a common Cummins part that can be bought cheaper elsewhere. Do you think it is the same as Cummins 3910992?
Attached are three photos...top is the parts book for Case 860 trencher. I need elbow, clamp that attaches it to turbo, and the L bracket (11) could also be replaced. Any leads appreciated.
Thanks

Not sure if this helps you Austin as p# is digit off... this 90 came with my motor and fits my hx30w and my hx30 super, front to back is 5in x 7in long the outlet is 3in od... also has the port for a pyro probe...not sure if this will work for me as I am still working to get the motor mounted... you might look into a cobra head hot pipe.

Austin, if you only have about 4.5" that one is sort of ruled out. Needs at least 5" and that is tight. Here may be a couple possibles and I emphasize may be. One is part 4939408. That is a relatively new part but not sure which turbos it fits. It may be for an HE221W which has a different flange than the HX30W/HX35W. Never had one of these so can't really judge how big the overall size is.

Here is another possible. This one came on the HX35W so it would fit an HX30W. It's a simple elbow and may fit your space. It has the clamp flange on both ends so you'd need a section of down pipe with the flange. Part number is 3959261. It's going to be close to 4". Outside of a cobrahead, that is about as tight as the bend can get. Found one source that lists this one for $818.62. Bet they sell a 1000 of those a week. LOL. Another guy was even better at $913.36. That must be some powerful weed those guys are smoking. There's a used one on ebay for $49.99 incl shipping and a brand new one for $49.95 or best offer. From looking at the photo I believe the turbo side flange is half Marmon and the exhaust side if full Marmon but that could be the camera playing tricks on my eyes. I had one of these but no idea where it might be.

That's good to know. On that one there is stud boss near the large end. That could be removed if it was in the way. A photo below shows one installed and he did remove that boss. Also, when mounted the exhaust pipe flange is offset toward the block if the turbo is in normal position. In use the turbo was mounted reversed with the exhaust facing the front. It was designed to be an extremely tight fitting package. That bottom flange is 4.5" OD, 3.5" ID. This part came on an ISDe 6.7 Cummins. May need a small dent in the firewall for clearance. Also this thing is designed for a big exhaust pipe. At least 3.5".
