Turbo- Blue Printed?

[JP825]

Sorry for being stupid but what does it mean to get a used turbo blue printed?? :confused:

Also is little shaft play normal on used turbo? How mcuh will it cost to get a turbo blue printed or rebuild??

Many thanks in advance.. :D

Rebuild costs will vary considerably depending on the turbo. A certain amount of shaft play is normal and should be taken out by the oil flow once its running. Theres a few places for turbo rebuilds in this area but probably your best bet is AET in Normanton, give them a ring with details of what your turbo is and they should be able to give you a rough idea of cost

If I have got it right - when you have an engine block blue printed then what they do is paint it with some sort of blue coloured liquid. When it dries they clean it all off. The colour remains where there are cracks which of course can get bigger and cause a failure.

no, blue printing means to rebuild and select components that are the best possible match yet still within the range of the manufacturers tolerances. (as defined on the "blue prints") They can also be machined to make them the size required to achieve that.

imagine if you had a part with a hole and another with a pin. Out of the "stores" you could take 100 of each part and each one would vary slightly in size within certain limits. Fair enough all of them would fit together (assuming they were designed correctly) BUT if we now decide that we want this specific assembly to be used for a one off that will need to be as good as it possibly can be (like a press car LoL ) and that the best situation is to have the least clearance between the pin and the hole you could measure each and every one of the 200 components and pick the ones that give the best clearance.

The term blue prints will come from the "blue prints" that used to be made by a certain method of reproducing engineering drawings.
