Turbocharger HX40W 2839309 2881753 Cummins Industrial QSL

Once these bolts are removed, the turbocharger can be lifted out. Set the assembly on the bench and be sure to remove the actual oil drain pad if there is one on the underneath side of the bearing housing. The next step is to index the relative positions of the turbine housing and compressor cover relative to the bearing housing. This can be done with a simple punch or small chisel to mark the locations. Next, mount the turbo in a heavy vice by the turbine foot. The housings will be connected to the bearing housing by either bolts or a V-band connection. If it is a V-band connection, you’re lucky. Simply place a bit of penetrating oil on the V-band threads and you should be easily able to remove the V-band on the turbine side first. If there are bolts, remember the penetrating oil and setting-up vibration trick to help loosen the bolts more easily. Once the bolts and/or V-band connection is released, there may be some difficulty in freeing the turbine housing from its centering pilot on the bearing housing. More penetrating oil and some gentle persuasion with the aid of a brass hammer may be helpful.
