Leybold Trivac D8B
We need a roughing pump for our turbos. I bought this unit a while ago, and it works, but it also makes funny noises.
Plan
It needs to be opened up. I may have to fabricate and/or purchase some new parts to get it back to a more usable state.
Teardown / Rebuild
Fully disassembled pump module
First and second stage vanes
First stage vane in pump module segment
Original busted gasket and temporary laser cut silicone replacement
Freshly polished gasket surfaces of pump main mount and housing
Shaft seal driver. This tool makes it harder to screw up when installing new shaft seals.
Link to the STL for the shaft seal driver.
For those who wish to replace the shaft seals without being extorted by Leybold, they are regular FKM GR 15x24x6.5 SS 304 spring oil seals. Available as a general commodity item.
