We bought this used about a year ago, runs well, but the exhaust side of the turbo is just burnt through all over the place, and we're trying to find a new one. What's odd, is the center turbo cartridge which has 2 pipes on all I can find - an in and out for the oil, mine has a third which connects down behind the fuel pump area and it's a type of compression fitting on both ends (no bolts or gaskets). I cannot figure out what that 3rd line is for, nor a turbo to buy and replace ours. ANY help is greatly appreciated. The dozer is covered in layers of paint, the only # persay that I can find on the engine is on the oil filter side of the motor, on a plate, reading 76A1910.

Can anyone help decipher this and possibly know what sort of turbo I have, or part number for the turbo which has 3 connections on the Turbo Cartridge.

Thanks!!!

 

Thank you, seems to be the 1964 as I suspected.  Any idea about this TURBO that has 3 lines going into the Turbo Cartridge?  All I can find is a line in and out (with bolts and gaskets),  On the facing side of the turbo I have a 3rd line which is a metal 3/8 to 1/2 inch compression type fitting coming from the Turbo Cartridge to the back of the fuel pump/system.  I have removed the turbo as it's just cooked.  It works fine but the exhaust end of the turbo is just burnt through in so many places, and where the # would be for the turbo has been repaired and braised/welded so I cannot even get a PN for it.  We're in desperate need of an entire turbo or at least the exhaust side of it.

Hi there, sorry for the delay in posting some photos - work is nuts! So if you look at these images, you can see the bolt in top and bottom oil tubes on the Turbo Cartridge. You'll also see a roughly 3/8 to 1/2 inch tube with a compression type fitting on both ends which also attaches to the Turbo Cartridge and then travels behind all of the fuel pump/system and screws in behind it. The tape on the tube in question is to just keep it together for reference as it twisted in half when removed.

 

This probably just muddies the water but here are the part book pics. The first pic is the turbocharger oil lines, note there are only 2 listed. The second pic is the turbo and a third line listed for Accessory Drive.
