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

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

Product Information
Product Information

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.

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.

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.

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.
