Crankshaft bolt gasket

This goes under the flywheel bolt, when you bolt the flywheel to the crankshaft. This was made standard starting in 2023 and works on all Urals. Without this, you need to apply silicone sealant to the flywheel bolt threads, to prevent engine oil leaking past the bolt and into the flywheel (and onto the clutch).

We use this gasket every time we install a flywheel.
