This component is an oil seal, often referred to as the “large oil pump / oil cooler seal.” Its job is to prevent oil from leaking at the joint between the oil pump (or oil cooler housing) and the engine block or other mating surface. It maintains pressure integrity within the oil circuit, preventing external leakage and loss of oil. A proper oil seal helps protect surrounding engine components (gaskets, housings) from oil contamination and keeps the lubrication system efficient.

Location: Mounted at the interface of the oil pump or oil cooler to the engine block — typically around a rotating shaft or coupling.
Function: Provides a leak-proof seal for high-pressure oil flow between engine and pump housing
Installation: Direct-fit OE replacement — replace whenever the pump or cooler is removed
Maintenance Tip: Always replace during engine rebuilds or if any oil seepage is detected near the cooler or pump area

Why replacement matters:
• Over time, the original seal can harden, crack, shrink, or wear due to heat, pressure cycles, vibration, and exposure to oil and contaminants.
•  A compromised seal allows oil to leak, reducing oil level, lowering system pressure, and potentially causing damage to engine internals.
•  Even small oil leaks can lead to oil contamination of belts, hoses, or nearby components, making clean-up costly and potentially damaging.
•  Replacing with a high-quality replacement seal restores full sealing integrity, ensuring proper oil circuit function, preventing leaks, and protecting the engine’s internals.

When to replace:
•  Whenever the oil pump or oil cooler is removed for maintenance, repair, or rebuild — always replace the seal rather than reuse an old one.
•  If you detect oil seepage or external leaks near the pump / cooler area, or during engine inspections.
• During major engine overhauls, rebuilds, or upgrades, especially in older or high-mileage engines.
• As preventive maintenance in high-stress or high-boost applications, where oil pressure and temperature are elevated.

Oil pump tab washer.
Oil pump tab washer designed to secure and lock the oil pump fastener on classic Porsche engines. Although small, this locking washer plays a critical role in preventing oil pump hardware from loosening due to engine vibration and repeated heat cycles.

Fits:
Porsche 911 1965 - 1986
Porsche 911 Turbo 1975 - 1977
Porsche 914 1970 - 1976

Diagram ref no 4

By acting as a mechanical locking device, it helps keep the oil pump firmly in position, supporting stable oil pressure and reliable engine lubrication. Proper retention of the oil pump is essential for long-term engine protection and performance.

Tab washers are intended to be bent into place once. Reusing a previously bent washer can cause metal fatigue and reduced holding strength, increasing the risk of fasteners backing out. Replacing the washer during service is a simple, low-cost way to safeguard engine reliability and prevent premature wear.

When to replace:
• During oil pump removal, refit, or engine rebuild
•  If the washer tab has been previously bent or straightened
•  When cracking, distortion, or fatigue is visible
•  Any time oil pump fasteners are loosened during maintenance

Oil pump tab washer.
Oil pump tab washer used to secure and lock the oil pump fastener in place on classic Porsche engines. It’s a simple but important locking washer designed to prevent the oil pump hardware from loosening due to engine vibration and heat cycles.

Fits:
Porsche 911 1965 - 1986
Porsche 911 Turbo 1975 - 1977
Porsche 914 1970 - 1976

Diagram ref no 4

It acts as a mechanical locking device for oil pump hardware, reducing the risk of fasteners backing out over time. By keeping the oil pump assembly secure, it supports consistent oil pressure and dependable engine lubrication.

Tab washers are designed to be bent into position - and once bent, they can fatigue or lose holding strength if reused. A weakened or reused tab washer can allow oil pump hardware to loosen, which may contribute to oil pressure issues and accelerated engine wear. Replacing it during service is cheap insurance for engine reliability.

When to replace:
•  During oil pump removal/refit or engine rebuild work
•  If the existing washer tab has been previously bent/straightened
•  Visible cracking, distortion, or fatigue around the tab
•  Any time oil pump hardware is loosened as part of maintenance

OE Match upper oil-pump gear with tachometer drive for Porsche 356 B, 356 C and 912 applications. Intended for the later, larger pump design, it incorporates a shaft whose driving fin engages the camshaft slot.

Fits

• Porsche 356 B 
• Porsche 356 C 
• Porsche 912

The 356 lubrication diagram covers 356B / 356C 1960–1965 and includes engine-number restrictions detailed below. Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

This gear and shaft form part of the engine's oil-pump mechanism. Engagement between the shaft fin and camshaft transfers rotation into the pump assembly, which circulates lubricating oil through the engine.

Functions

• Transfers camshaft rotation to the oil-pump mechanism.
• Works with the pump's mating components to circulate engine oil.

Technical Details

• Component: upper oil-pump gear and shaft for the later large-style pump.
• Supplied references: 61610701601 and 61610701600.
• Reference 61610701600 appears in the 912 lubrication diagram as oil-pump shaft I with gear.
• Reference 61610701601 appears in the 356B / 356C lubrication diagram as oil-pump shaft I with gear.
• Listed 356 engine variants: 1600, 1600 S and 1600 S90.
• Recorded 356 engine-number cut-offs: M 601 995 >>; M 85 941 >>; M 800 150 >>.

Symptoms of Fault

Inspection may reveal deterioration of the driving fin or wear around the shaft's bearing end. Low pressure once the engine is hot, delayed pressure build-up or metal particles in the oil also warrant investigation, but do not establish that this gear is responsible.

Why Replacement Matters

Renewal is appropriate when inspection confirms damage or wear affecting the gear or shaft. During pump work, assess the mating gear, housing, camshaft engagement and associated sealing components rather than replacing this item in isolation without checking their condition.

FAQs

• Does low oil pressure prove the gear needs replacing?
  No. Verify actual pressure and investigate oil condition, bearing wear and other lubrication-system components before identifying the cause.
• What should be checked before fitting?
  Confirm the pump design, original reference and applicable engine-number restrictions, then inspect the shaft engagement and surrounding components.
• Should disturbed seals be reused?
  Renew the relevant gaskets and seals during reassembly using the correct specification for the engine.

• Forms part of the pump's rotating mechanism.
• Contributes to engine lubricant circulation.
• Provides the specified version without a tachometer-drive connection.

Technical Details

• Internal diagram description: oil pump shaft II with oil pump gear.
• Pump application: later large-type assembly.
•  markings include (D) (S), 1600 C and 1600 SC.

Symptoms of Fault

Inspection may reveal deterioration at the drive fin or bearing end. Low pressure with a warm engine, delayed pressure rise after starting, abnormal mechanical noise or metallic contamination also warrant investigation, but do not establish that this gear is responsible.

Why Replacement Matters

Renewal is appropriate when inspection confirms wear or damage. During pump work, assess the mating gear, housing, drive connection and sealing components rather than replacing one item without checking the surrounding assembly.

FAQs

• Does a low pressure reading prove the gear is worn?
  No. Check actual pressure before attributing the fault to the pump; the sender, oil condition and other internal wear can affect diagnosis.
• When should replacement be considered?
  During a rebuild or lubrication-system repair when measurements and inspection identify deterioration.
• Can existing seals be reused?
  Renew disturbed gaskets and seals as required by the applicable workshop procedure to reduce the likelihood of leakage after assembly.

OE Match oil pump for selected Porsche 911 and 914-6 engines. Reference 90110700206 identifies the pump within the supplied engine-lubrication diagrams.

Fits

• Porsche 914-6 1970-76
  
  

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram ref no: 1

What This Product Does

The pump moves oil through the engine lubrication circuit, supplying the flow needed at internal moving surfaces. It works with the remaining lubrication components rather than replacing the roles of the filter, cooler or pressure-control valves.

Functions

• Circulates lubricant through the engine.
• Provides oil flow to support lubrication pressure.
• Supplies moving components with oil to limit friction.
  
  

Technical Details

• Product reference: 90110700206; brand: OE Match.
  
  

Symptoms of Fault

• Lower-than-expected pressure with the engine hot.
• Delayed pressure rise after starting.
• Lubrication warning illumination or unstable gauge readings.
• Tapping from the valve gear or particles of metal found during oil inspection.
  
  

These signs do not establish pump failure on their own. Oil condition, bearing clearances, pressure-control components and the sender also require assessment.

Why Replacement Matters

Renewal is appropriate when inspection confirms pump deterioration or testing traces inadequate pressure to the pump. Checking it during an engine rebuild allows wear and contamination to be assessed before reassembly. Inspect associated sealing components and follow the engine-specific fitting procedure.

FAQs

Does a low reading prove the pump is worn?
No. A faulty sender can produce a misleading indication; mechanical pressure testing helps establish the actual condition.

Should seals be checked during installation?
Yes. Review the required seals and associated hardware rather than assuming existing components can be reused.

Can low pressure be ignored?
No. Stop the engine and investigate promptly, as inadequate lubrication can damage internal components.
