Information
O-ring power steering pump drive train
Genuine Porsche OE O-ring for the power steering pump drive train on Porsche 964 and 993 models. This original Porsche 40 x 4 mm O-ring seals the power steering pump drive / camshaft drive housing area, helping prevent fluid or oil leakage from the power steering drive assembly.
Sold individually
Fits:
Porsche 964 1989 -1994
Porsche 993 1994 - 1998
Diagram ref no 3
What This Part Does / Functions
• Seals the power steering pump drive housing connection
• Helps prevent leaks from the pump drive / camshaft drive area
• Maintains correct sealing around the power steering pump drive train
• Supports reliable power steering pump operation
• Replaces a hardened, flattened, cut or leaking original O-ring
• Provides correct OE Porsche size, material and fitment
• Supports correct reassembly after power steering pump or drive housing service
• Helps maintain factory sealing performance.
Why Replace This Part?
O-rings are exposed to heat, oil, fluid, pressure changes and age-related hardening. Over time, the rubber can flatten, crack, swell or lose elasticity. Once the power steering pump drive housing is removed or disturbed, the O-ring should normally be replaced to ensure a reliable seal when reassembled. Replacing it with a Genuine Porsche OE 40 x 4 mm O-ring helps restore the correct seal and reduce the risk of leaks around the power steering pump drive assembly.
Common Symptoms of a Failed O-Ring
• Fluid or oil leakage near the power steering pump drive area
• Residue around the camshaft / power steering pump housing joint
• Power steering pump area seepage
• Hardened, flattened or cracked O-ring during inspection
• Persistent leak after previous pump service
• Oil smell from hot engine components
• Fluid drips underneath the rear of the engine area
• Seal damage after power steering pump removal.
When to Replace This Part
• When removing or refitting the power steering pump drive housing
• During power steering pump service or replacement
• If leakage is found around the pump drive / camshaft seal area
• If the O-ring is hardened, flattened, cracked or damaged
• During engine or power steering system repair
• When resealing the power steering pump drive assembly
• After separating the power steering housing from the camshaft drive area
Where It Fits on the Car
This O-ring fits in the power steering pump drive train / camshaft drive housing area. It seals the joint between the power steering pump drive housing and the engine drive location on compatible Porsche 964 and 993 models. Correct installation is important. The sealing surfaces should be clean, and the O-ring should be fitted without twisting, pinching or damage.

Information
Hylomar Gasket 3400 is a modified anaerobic curing, flexible sealant designed to become a Formed in Place (FIP) Gasket when cured. The cured compound has good temperature resistance and high resistance to fretting. The cure is initiated when the compound is in contact with metal ions and in anaerobic conditions. The cure rate and final strength is dependent on the metals being joined and the temperature at which the component is used. The heat generated by a running engine will accelerate the cure.
Typical Applications
Hylomar Gasket 3400 can be used as a gasketing compound between machined surfaces. It is ideal for sealing between mating faces on engines and transmission components where resistance to temperature and vibration are essential.
INSTRUCTIONS FOR USE
Hylomar Gasket 3400 should be applied to clean and dry surfaces, free of contamination such as oil or grease. The compound may be dispensed by hand from cartridge, concertina pack, or via a screen printing system. Once applied the joint should be assembled as soon as practical. Any excess compound can be easily wiped off external surfaces with a clean cloth soaked in Acetone or other suitable solvents.
