Information
Rear main oil seal - crank rear.
Fitting Position: Transmission End
Inner Diameter: 90 mm, Outer diameter: 110 mm, Width: 12 mm
Radial Shaft Seal Design.
Fits:
Porsche 911 3.0L 1978 - 1983
Porsche 911 3.2L 1984 - 1989
Porsche 930 Turbo 1975 - 1989
Diagram Ref No 33
The rear main oil seal fits at the rear of the crankshaft where it passes through the engine case. It helps retain engine oil inside the crankcase and prevents oil from leaking into the flywheel, clutch, or transmission bellhousing area.
Functions
• Replaces the rear crankshaft oil seal
• Helps seal the rear of the engine crankshaft
• Helps prevent engine oil leaks from the bellhousing area
• Protects the clutch and flywheel area from oil contamination
• Supports correct crankcase oil retention
• Replaces hardened, worn, split, leaking, or damaged original seals
• OE Match replacement for Porsche 911 and 930 engine service.
Why Replace This Part?
Rear main oil seals are exposed to heat, crankshaft rotation, oil, pressure changes, and age-related wear. Over time, the seal can harden, shrink, crack, wear, or lose sealing ability. A failed rear main seal may cause oil leaks between the engine and gearbox, oil contamination on the clutch, burning oil smells, or visible oil dripping from the bellhousing area. Replacing the seal helps restore a clean, reliable crankshaft seal.
When to Replace This Part
• Oil is leaking from between the engine and gearbox
• Oil drips are visible from the bellhousing area
• The clutch or flywheel is contaminated with oil
• The engine or gearbox has been removed
• The flywheel is being removed or replaced
• The original seal is hardened, worn, split, or leaking
• Preventative replacement is being carried out during clutch or engine service.
Where it fits on the car
This oil seal fits at the rear crankshaft position on Porsche 911 and 930 engines. It sits between the crankshaft and engine case, behind the flywheel area.

The clutch flywheel purpose & function
A flywheel in general (for a manual-transmission car) has several critical roles:
• Mass / inertia storage — It smooths out the pulses of the engine, aiding when cylinders fire and bridging the gaps between combustion events.
• Clutch friction surface — The clutch disc presses against the flywheel, so the flywheel must have a suitable, stable friction surface.
• Crank / sensor interface — In this case, because it is used with Motronic control, the flywheel provides trigger pulses (teeth or marks) used by the engine control (DME) to know crankshaft position or engine speed.
• Balancing — It must be precisely balanced (often as part of the entire rotating assembly including crank, flywheel, clutch) to avoid vibration and stresses. If the flywheel is worn, warped, cracked, or misaligned, all of these functions are jeopardized (vibrations, clutch slippage, sensor error, etc.).
Common failure modes / why / signs & symptoms
Because the flywheel is a high-stress rotating component, over time or under strain it is subject to wear, damage and failure. For this particular part and era, here are common issues:
• Surface wear, scoring, glazing, heat spots on the friction surface: repeated clutch engagement or slipping can overheat zones, creating hard “spots” or cracks.
• Cracks / fractures: under severe stress or impact, cracks can develop, especially around bolt holes or near sensor teeth.
• Distortion (warpage): heat cycles may warp the flywheel face so it is no longer flat, causing uneven clutch engagement or chatter.
• Sensor trigger damage: damage or wear to the trigger teeth or notches may make the engine control module misread crank position or lost signals.
• Bolt failures / loosening: the 9 bolts attaching the flywheel to the crank are critical; if they stretch, loosen, or fail, misalignment or imbalance can result.
• Imbalance / degradation of balancing: over time, if the mating surfaces or mountings shift or fatigue, the initial balance may be compromised, introducing vibration.
• Oil contamination: if the rear main seal or other seals leak oil onto the friction surface, the clutch/flywheel interface becomes compromised (slippage, glazing).
• Fatigue / wear of dowel pins or alignment features: if alignment dowels (or roll pins) degrade or are missing, mounting may be off, leading to misalignment. In a forum thread, a user found small roll pins (alignment inserts) that had come off the flywheel.
