looks like i will be doing it as you say !!.................just will try tomorrow one more option.....then it will be the tap job.....................

if it was it would take me 15sec's to cut the grass................i would be cutting at Warp factor 3....captain..........(off a landrover...its a spare turbo i blagged a while ago)

done that.................................

ive been fiddling........................not good ...it isnt working as i thought...........ive got a mate coming over tomorrow to give me a hand........have drilled the bolt out....christ it was hard had to sharpen the bits 4 times.....the bolt is so hi-tensile it wont fold like it should...so i am going onto plan B.....give that a try......then plan C....which is the option i dont want to go to........... everything is a learning curve...................

if it starts well.......then your timing is not far out.................do a few miles in it and all of a sudden the smoke will disapear as the rings cut their own bed........dont worry about it

christ that looks smart ............

im just making this up as i go along ......................

Trust me..................

i think they all ought to be housed at Hogwarts.....

wont be using bolt extractor......i will progressivly drill it out as much as i dare then make something out of an old chainsaw file and fold it in on itself..........not rocket science....its what you did before bolt extactors..............the thing is with all this heat it has rust welded its self to the threads....so spinning it out with an extractor might not work without heat...........if you do add localised heat to the casting..........it will crack....and this is a very good casting ....i dont want to scrap it...

right this is the last lot for today pic 1......exhaust turbine chamber......filthy dirty....could be a number of things...landrover not worked hard enough.....wrong oil......wrong timing......boost pin wound back in....jammed waste gate....split actuator........ pic 2....inside the shield ugh wet soot....all of the insides should just be covered with a light dry soot... pic 3 ...the exhaust seal....like a piston ring .. pic 4....turbine in housing pic 5 ...carrier ready to take out tomorrow thats your lot today........

first pic is the carrier at the exhaust side of the charger...there is a weeny circlip that holds it in place....i will have a good clean up then i can see it proper to remove it....should just drop out... 2nd pic is the guts of the cassett.....not much really 3rd pic is the bolt i will drill out tomorrow 4th pic is what it should look like...the hole goes right thro to the exhaust turbine housing...which will make it easy to drill out as i dont have to be worried about the depth.............

next thing to do is lift out the "carriers"........now "i" call them carriers as they are not strictly bushes or bearings.... you have 2 of these one each end of the shaft....when you check a turbo...you check for end float............(which you dont want none of) verticle movement (you will have a bit ...maybe 1/16") the idea is these carriers are pressurised with oil at 30lbs/sq"....and as a result the shaft is "floated"....the shaft when turning does not really touch the carriers as it is floating on a thin film of oil............it needs to as the turbine will spin in excess of 120,000 RPM some turbines will spin at a 150,000 rpm !!.......................

i will do that tomorrow.....ive got a few more stripdown pics to put up yet.......

first pic is the turbine shaft....and the other pics are of the centralising bush/seal......these have "funny" screws in them and are TIGHT...so make sure they are cleaned out before you try and unscrew them....and they go back in with locktight (other brands are available) looking at the turbo now...im not happy with the cassett the engine has been timed wrong and it is wet sooted up which acts like a grinding paste....the exhaust and compression bodies are in really good condition....the turbo has never been brought up to temperature properly ....so i will swap over an old cassett and marry that to the good stuff when i get the rebuild kit.........you will see how bad it is wet sooted up later on....

GENTLY tap out the shaft...and the shield will come out as well ...then remove the cover plate from the other end.............

now that is warm.................

so the cassett is now free of the chambers.........you can see where i have to drill the bolt out now......last 2 pic's show the removal of the compressor turbine 8mm nut................REMOVE THIS NUT CLOCKWISE (SPINNING SHAFT OK) then a little gentle heat on the turbine and lift it off

so the circlip comes out and the pressure chamber comes off.......then it is time to drift the cassett out of the exhaust turbine chamber....only drift on the body of the cassett as the edges can get damaged....last pic shows it is starting to move...

next pic's show where it (the bolt) snapped off and removing the studs from the exhaust manifold...the last one shows the circlip that needs to be removed to take off the turbine compressor housing (aluminium)

Test.................right i think ive got it now......had a new pic' program loaded onto the new computor...had difficulty arranging the settings...so i will alter them as i go on..... first pic shows the turbo to be rebuilt against the rebuilt engine one...the next 3 pics show the exhaust turbine chamber..and the 4 bloody bolts that have to come out....which hold the cassett/turbine shaft in ***'......annnnd...yup as usual one of the bolts has snapped off........if you heat that area of the turbine exhast...it usually ends up cracking...so once i have cleaned it all up i will start to drill it out...

enjoyed that...

get one of those and a cheap turfer and you will never get stuck...as said earlier...if you are taking it to uni (Landy) prepare for it to dissapear.....also you insurance will reflect that it is not kept at home ...and they will sting you...

yes they have come a long way since my fiddling time with them ...they are also variable pitch turbines now i believe....far tooooo complicated for me ....

ouch.............. ....just how it should be..............BALA will be along in a minuet
