I have been working away at the rebuild, making progress.
-reman crank
-new water pump shaft
-Wossner top end
-Indy Specialty turbo head
-new OEM oil pump
-all oil injectors tested
-new turbo CHRA
The turbo oiling system is:
-Facet posi-flow pump
-Mr Gasket coolant recovery tank for old hot...
gedakbx, I spoke with Justin early in the saga. He was helpful with suggestions, and would inspect the turbo for warranty if I sent it to them. Not really the quick solution I needed. I don't want to rebuild everything and start riding not knowing if it will just happen again.... hence my search...
ABMax, Silbers turbos are ceramic bb so no need for high volume or pressure. I'm going to research the pump you suggested, sounds like a good solution.
As for why the turbo has overheated...... simply because after my water pump fails, I ride the sled out without a functioning cooling system...
Hope your all having a good summer!
I have some issues to deal with before snow flies, time to get at it.
2019 Axys 850 with a Silber 2.0 kit.
Twice now my water pump gear has failed from what is surely a lack of lubrication to the center cavity. Even though nobody else seems to be having my...
So, I've been doing some tweaking with the idle speed.
-idle speed was low on cold startup when I installed the turbo, so I had adjusted it up a little.
-now I lowered it back down, which seems to have helped a lot with the run-on. Idle is @ about 1100 - 1200 cold, once warmed up it's @ 1650...
Yeah I'll talk to Silber, but they don't use or sell bov's for 2 stroke kits. Someone somewhere has bov'd a silber polaris I figure lol.
I'm capable of drilling / tapping for the vac nipple, hoping someone has a setup to share for the rest.
With the engine still installed I could get the wp cover off, but I don't think it would be possible to work on seals. Maybe with the mounts un-bolted and tip the engine back? at that time your so close to just pulling the engine.
-To update the bearing, the cases would need to be machined for the ring so that wasn't gonna happen.
-Not a sled mechanic, but previously was an auto mechanic. I have also been working on my own sleds and dirt bikes since I was a kid. Most of my testing is outlined in the service manual.

Installed a Silber kit on my 2019 Axys 850 @7psi. Running great, loving my first turbo sled!
There's a moment of "run-on" coming off boost. Not an issue at all in deep snow, but can be annoying from time to time on higher traction.
The held rpm seems to be linked to boost left in the system, as...
