Posted in General Technical too !!!
Hi, anyone know where I can get a guide (or point me to something in the FAQ etc.) or somesuchlike for repairing my TD04, if I was to buy the repair kit myself?
Cheers, Neil

 

I think the repair kits/service kits are not worth selling to the general public. Its my understanding that a turbo has to be balanced. To do that, it has to be spun at 50,000rpm or something like that.

 

Possibly not worth repairing anyway as you'd probably pick up a low mileage second hand one for 60quid or so ?

 

I think it is only the seals that have gone so won't be replacing any impeller parts etc. that would affect the balance so was going to give it a go. Can get the parts esily but wondered if there were any guides out there that would point out any pitfalls etc. Cheers, Neil

 

If your interested, I have one of these sat in my house doing nothing.

If you want it, it's yours. It's come off a MY03 WRX on 50K.

Let me know.

Is that right mate ? Ive just bought a repair kit for my TD05 for £60 and the guy told me it was just a case of stripping it down and replacing the parts,he never mentioned balancing the turbo !! Anyone throw some more light on this ?

 

I suppose it does depend what is in the kits. Whats in the one you have?

 

This apparently !

BEARINGS X 2
SNAP RING X 2
SPIRAL RING WITH OFF SET X 2
THRUST BEARING
O RING (INSERT)
PISTON RING (COMP)
SNAP RING (LARGE)
SHAFT NUT
PISTON RING ( TURB)
GASKET

What do you think ??

 

Just seen your one on ebay. I was always under the impression it is a specialist job, especially the thrust bearing and compresser side of things. But all of the ad's on ebay state it can be done with normal tools, so I stand corrected. Keep us posted on how you get on.

 

I spoke to a guy at a turbo place up north (where I live) and he thought that anybody who was reasonably mechanically minded should be able to strip, replace parts and rebuild the turbo, it doesn't need any special tools as such. He mentioned that the 'refurbed' ones that they sell would be pressure blasted (cleaned) and balanced, but he couldn't or wouldn't tell me how they do it! Figure that as long as you mark the relative positions of the exhaust and compressor wheels on the shaft and put them back on in the same place/orientation then you should be OK.
Cheers, Neil

 

I will let you know how I get on if I ever get round to doing the job !

 

You have PM !!

 

Turbos are very basic devices, so yes thay can be rebuilt DIY; Providing the only problem is minor bearing play or seal problems. Certainly the advice to use a professional is given by someone who has never done it themselves, LOL.

The main issues is if the shaft is damaged/worn or the impellars have been damaged (say, from lumps of carbon or blades hitting the housing). Or if the bearings have spun within the housing. In which case a rebuild kit won't suffice.

If you can't find a manual (which I don't have, I'm afraid). I would suggest going to a scrap yard and getting hold of an old turbo and strip it down yourself to familiarise yourself with the general way they go together; like engines, turbos in general are much of a muchness between manufacturers and types, they just need a methodical approach in dis/reassembly.

But a manual would be handy to measure tolerances. It seems the industry want to keep these under wraps to protect themselves and keep knowledgable people capeable of doing such a task under a blanket of ignorance, and make them think that they are magic devices that can only be messed with by "Specialists".

 

Ive done some more research on this before attempting to repair my TD05 and the only likely problem is that I wont be able to balance the turbo myself.

Apparently aslong as you scribe the shaft before dismantling it so that when you reassemble it you can line all the parts up in the same way they were originally then all should be fine.

 

Also,check this guide out: Turbo Rebuild

 

Cheers, Might have a go myself, looks a doddle!!

 

if you are thinking of rebuilding your turbo i have found a site that sells rebuild kits for a reasonable price $68 for td04 and $76 for td05 roughly £40
G-Pop Shop Home and look at mitsubishi kits

 

I would be inclined to go for a low mileage used Turbo -
if the Turbo you have just overhauled decides to self-destruct and dumps its
innards down your Inlet ports - the price of an engine rebuild is a lot more
than a good second hand Turbo

 

Thats what I went for in the end,just as I was about to repair my TD05 another one came up for sale with an uprated 360 thrust bearing. So now I have a TD05 that needs the seals replacing and a repair kit to go with it if anyone is interested ??

 

Look for Cornelius in the ESC events .... he has rebuilt a TD05 20g

 

Where can you get the rebuild kit with the 360 degree thrust?

 

Search ebay for TD05 repair kits and you'll find them,the uprated kit with the 360 thrust bearing is about £200 though I think !

The turbo I bought had been rebuilt by Turbo Technics
