- Porsche 356B 1959-63
- Porsche 356C 1963-65
OE Match lower oil-pump gear incorporating a tachometer drive, intended for Porsche 356 B and 356 C applications. This replacement component suits the later, large-style pump assembly.
Fits
- Porsche 356 B — 356B 1959–63
- Porsche 356 C — 356C 1963–65
Fits late style "large" oil pump
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
This component combines the lower pump gear with the drive for the mechanical tachometer. Within the pump assembly, the gear works with its mating component to move engine oil through the lubrication system. It is an individual internal component, rather than a complete pump or gasket kit.
Functions
- Works with the mating gear to circulate engine oil.
- Provides the mechanical tachometer drive.
- Replaces the lower gear component during suitable pump repairs or engine rebuilding.
Technical Details
- Brand: OE Match.
- Position: Lower, with tachometer drive.
- Internal diagram designation: oil pump shaft II with oil pump gear.
- Referenced part number: 61610701502.
- Diagram application context: engine lubrication, 356B / 356C, 1960–1965.
- Listed engine applications and starting numbers: 1600, M 601 995 >>; 1600 S, M 85 941 >>; 1600 S90, M 800 150 >>.
Symptoms of Fault
Conditions warranting inspection include unusually low pressure when the engine is hot, delayed pressure build-up after starting, abnormal mechanical noise and metallic particles in the oil. These signs do not establish that this gear is faulty; pressure-sender faults, bearing wear and other lubrication-system problems can produce similar symptoms.
Why Replacement Matters
Renewing a gear with confirmed wear or damage addresses deterioration within the pump assembly. During dismantling, inspect the mating gear, housing and associated sealing components rather than assuming that replacing one part will resolve every pressure or leakage issue. OE Match focuses on Porsche-specific replacement applications; checking the pump version and engine number remains essential.
FAQs
Does low pressure automatically mean this gear needs replacing?
No. Verify actual oil pressure and investigate the cause before selecting replacement components.
Should seals be checked during pump work?
Yes. Inspect the relevant gaskets and seals during dismantling, and renew those required for correct reassembly.
What should be checked before choosing this component?
Confirm the later large-style pump, vehicle application and applicable engine-number cutoffs.

- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 356B 1959-63
- 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.

- Porsche 356B 1959-63
- Porsche 356C 1963-65
OE Match oil pump upper gear without tachometer drive for Porsche 356 B, 356 C and 912. Intended for the later large-type pump, it supports repairs to the engine lubrication assembly.
Fits
- Porsche 356 B
Supplied model designation: 356B 1959–63. - Porsche 356 C
Supplied model designation: 356C 1963–65. - Porsche 912
Supplied model grouping: 911 1965-1968 2.0L / 912 SWB (F).
Check fitment for your specific vehicle (model, year, engine) before ordering. Confirm that the installed pump is the later large-type version and requires a gear without a tachometer drive.
What This Product Does
This gear forms part of the engine oil pump mechanism. Its drive-fin connection engages a camshaft slot, allowing the pump assembly to circulate lubricant through the engine. It is an individual internal component, rather than a complete pump or gasket kit.
Functions
- 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.
