Oil pump upper gear without tachometer drive. Porsche 356 B / 356 C / 912 › 61610701701

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.

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.
