turbo TDO5 servicing

here is my turbo TDO5 VR4rs..it is a secondhand item..got it from somebody in PJ with rm 500..looks very dirty and for sure oil leak found around the housing.. it does't look good to install in my engine..


now after cleaning i dismantled the turbo to see if any thing broken, defect or sign of damage..

remember to mark on area of compressor and turbine wheel position so i can reinstall it back without balancing..even though this is not a proper way to do it but at least it can minimize the danger of failer..100,000 rotation of wheel in a minute will caused a disaster if without balanced..

compressor housing after cleaning..but still looks dirty...n on right pic is 16G centrifugal compressor wheel..twin blade..u can measure the inducer and exducer 1.89 inch n 2.68 inch..

here is the repair kit for this turbo..its contained with 2 journal bearings 1 thrust bearing, piston ring clip, oil seal, O-ring and gasket

journal bearing replaced n u can see piston ring clip (located behind the turbine)is also renewed, this is to prevent an oil leak through the turbine wheel..compressor has sand blasted and polished then it looks nice n shining..

porting the inlet and outlet of turbine housing make it larger area but it difficult to polish caused of harden materials

here is before and during porting of turbine inlet port..all of this work was not be carried out at any workshop...i made my self at my working place during my free time..hehe save cos maaaa..
