Hi All,
As we approach Xmas and I don't have any events or car shows to do until possibly February...I thought I might pull the GT6041 engine down and give it a thorough clean and inspection, I don't anticipate any issues but want to make sure all is as it should be. I will take the opportunity to clean all the rust etc from the turbine housing and bearing cartridge and probably give it a couple of nice coats of high temp ceramic paint... and also give the comp housing a good clean and possibly a bit of a polish to make it look pretty.
A bearing and shaft inspection will be a mandatory requirement....again, I don't anticipate any dramas with it as the oil pressure has always been fine and I've had no evidence of rubbing etc.
I'll also take the opportunity to try and clean up the birds next of wiring in and around everything....that's a task in itself...not looking forward to that, have no-one to blame but myself though...I put it there..! ;-)
Cheers,
Smithy.

Hi Smithy
Lotsa pics please of what you find inside , we've never had a DIY engine with as many hours on it as yours .
Yep , Bearings should be fine ................LOL, they'd normally have 10,000 hours on them before even thinking about looking at them
Cheers
John

As you know, I usually only run it for ~4mins at a time... And yes I'll take some pics for you to peruse. I might make a start on the work this coming weekend. Cheers, Smithy. |

Hi Smithy
Yep , 1 hour .
LOL, I'm just an engine builder , once constructed I start looking around for something new to build .
Yesterday I was checking out the KTS Site for any new comp wheels , they make a 140 mm inducered wheel with a 200 mm exducer, with extended tip to 216 mm , that screws onto a GT6041 turbine shaft , maybe a bit of overkill , but would be interesting to do the numbers for a "bleed air" type engine , theres also a 122 mm inducer wheel with 151 mm exducer, 161 mm extended tip , or perhaps a titanium 104 mm inducer, 151/161mm exducer for some extreme pressures....................heh heh , like a kid in a lolly shop :-)
But, getting back down to earth, gotta get the 12/118 going first before going off on a tangent .
Cheers
John

Hi All, Firstly...Happy New Year to All. Secondly..I had a couple of hours to kill yesterday after mowing the lawn...decided to pull the turbine out of the GT-6041 powered Go-Kart, I've been wanting to do a turbine and compressor inspection for a while now so I finally had the chance. From experience I knew I may have issues getting the turbine housing off the bearing housing....some turbos just refuse to come apart due to corrosion etc....to my surprise mine essentially just fell apart after removing all the bolts and here's the result:    Sorry John...it's just "Boring"...there's no evidence of heat stress or rubbing etc...there's slight tinge of heat at the inducer blade tips but nothing to write home about. Also no evidence of oil leaking from the bearing housing and/or piston ring seal...not a drop...which is good to see. I'll post some more pics of the internals as I get a chance during the day.. Cheers, Smithy. |

More:    As can be seen...there's not much in the way of wear or damage...still kinda boring. The bearings and thrust plate look like new, so they can go back in..! I think just a clean-up and give the cast iron parts a coat of high temp paint and we should be good to go. Cheers, Smithy. |
