1 Turbocharger Overhaul Instruction Garrett TBP4 Before you read this instruction, I have to say sorry my English is not that good to describe it well about how to rebuild turbocharger. If there is anything wrong, any better words or suggestion for this instruction, just me to Kansai_sport@hotmail.com The T3/T4 rebuild kit you purchased from Kansai-sport is new and complete dynamic kit for T3 / T4 / T04B / T04E / TBP4 Eiji Takada in Osaka, Japan. 2007/12/22 Now let s see how to take apart of Garrett TBP4 turbo and change rebuild kit. Please remove the bolts between bearing housing and compressor housing and turbine housing.

Sometimes it is hard to swap bearing housing

If you can take apart it easily, of course,

2 Sometimes it is hard to swap bearing housing and turbine housing as there is much carbon. I will use acetylene to heart it and then we can swap it easily. If you can take apart it easily, of course, you can leave this step. Now we take apart the bearing system and turbine housing

3 Let us take apart of compressor housing and cartridge. Please remove the bolt. Be care! When you remove compressor housing, don t harm the same point of edge, it may damage the compressor wheel. Please remove the housing by harming different edge of compressor housing after you remove the bolts.

If you do not bolt it back together with ALL of the lines lined up, your turbo may end up being out of balance, and

4 Before you take apart of CHRA, please make sure to scribe a line across the compressor wheel, nut, and the end of the shaft at this time. If you do not bolt it back together with ALL of the lines lined up, your turbo may end up being out of balance, and it can quickly destroy itself. Place the turbine blade "nut" in a vice, and either use a T-handle socket to remove the compressor blade nut, or when using the ratchet, make sure to hold the socket so that the

When I removed the one in the picture, I was very careful to grab the ratchet at the rotating end and put all the twisting force directly through the

5 ratchet is only twisting the nut, not placing any side load on the center shaft. Evidently it is easy to bend the center shaft if you place too much of a side load on it when removing the nut. When I removed the one in the picture, I was very careful to grab the ratchet at the rotating end and put all the twisting force directly through the socket, without putting any side load on the shaft. Be VERY careful of the wheels, the blades can really tear your hands up. It is safest to wrap them in towels, because if the nut breaks free and your hands hit either wheel, you could be seeing a lot of blood.

Remove the turbine wheel and then you can take off the journal bearing and heat shield Please remove piston ring (Seal Ring) on turbine shaft and clean the carbon on shaft groove and shaft.

Remove the used piston ring and Polish up the shaft using 1200 grit sand paper to remove surface varnish then polish it with some kind of metal polish. For best operation the turbo shaft should shine with no scoring marks or dull spots. Rinse the shaft and exhaust wheel assembly under petroleum ether to get rid of all the polish

17 Here are two pins for two holes on thrust bearing. Remind you again here is an O-Ring Don t forget it

18 Lock the bearing housing and plate.

Oil feed line side When you wanna set the turbine wheel into the bearing system, make sure the gape of piston ring toward bearing housing s oil feed side.

19 Oil feed line side When you wanna set the turbine wheel into the bearing system, make sure the gape of piston ring toward bearing housing s oil feed side. That would reduce the percentage of oil leaking. Sometimes it is hard to push turbine shaft into bearing housing, please shake and twist the wheel to make the piston ring on the central and then you can push the wheel into housing easily

20 Make sure the thrust collar will move smoothly
