HP841 Disassembly

[Jetman]

Hello! I recently aquired an HP841 setup including the gearbox for $50 cad! I am currently in the process of tearing it apart to clean and inspect all the components, and I am wondering how the front ngv vane type of thing with the hub comes off? Any help would be much appreciated, Thanks

Was it just on there with a press fit...or maybe a larger snap ring?

I have some pictures here:

I will try to go out to the shed and find the housing to check after work today.

There is a large snapring on the outside which i removed. There is a bit of surface rust so that might be making it stuck...

Lucky man ! Where did you get it at that price Any more left ?

Cheapest I've seen so far is this www.ebay.co.uk/itm/284155051134 so you definitely got a bargain.

Seems Renault trucks introduced turbo compounding a couple years ago so soon might be a bunch of the parts available www.renault-trucks.com/en/newsroom/press-releases/10-fuel-savings-new-generation-renault-trucks-engines

Yeap I think Volvo Scania did too But too early to get cheap used ones

Some guy was selling it on facebook marketplace… couldn’t really believe the price either!

[richardm]

At that price it really was your lucky day

Yeah, it was just the snap ring and a snug fit. I just pulled the NGV off once I got the snap ring out.

If it is a bit tough, maybe a light tap with a rubber or plastic hammer?
