This Rear Crankshaft Oil Seal Installation Tool is specifically designed to properly seat the oil seal onto the rear of the Volvo D12 or D13 engine crankshaft without causing damage. It is constructed from durable, impact-resistant material to withstand repeated use in a professional workshop environment, unlike makeshift methods that can easily damage the seal or crankshaft. The primary symptom of using an incorrect installation method is a premature oil leak from the rear main seal area shortly after installation.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The primary symptom of improper installation is an oil leak from the rear of the crankshaft shortly after the engine is run. If the seal is damaged during installation, it will fail to contain engine oil, leading to significant oil loss and potential damage to the clutch or flywheel.
Before using the tool, lightly lubricate the crankshaft and the inner lip of the new oil seal with clean engine oil. Ensure the tool is centered on the crankshaft snout and apply steady, even pressure to drive the seal straight in.
When replacing the rear crankshaft seal, inspect the crankshaft snout for any scoring or damage that could prevent a proper seal.
