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

- Porsche 356C 1963-65
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.
