Bearing clearance gauge kit

plastigauge


Kit includes:
1 x Plastigauge PL-A box 
1 x Plastiguage Mineral grease 
1 x Plastiguage Silicone grease 

PLASTIGAUGE PL-A is widely used in the measurement of clearance in plain automotive bearings. Measurement of clearance in big-end bearings can be achieved without dismantling the crankshaft.

Diagram ref no 10, 11 & 12.

Each bearing shell is produced with smooth, low-friction bearing surfaces and consistent wall thickness to maintain correct rod-to-crankshaft clearances when installed in the rod big end. The standard size designation indicates these bearings retain factory bore dimensions, ideal for engines where no crankshaft undersize machining has been performed.

Big end bearing shells provide the low-friction interface between the connecting rod and crankshaft journal. They help to support dynamic engine loads and maintain a stable lubricating oil film that protects both the rod and crankshaft from metal-to‐metal contact. With proper oil flow and clearance, these bearings help ensure reliable rotation and reduce wear under normal and high-load conditions.

Installed in pairs inside each connecting rod’s big end bore, these bearing shells support the rotating crankshaft by maintaining correct clearance and offering a durable, smooth surface for the journal to ride on. Their design promotes even oil distribution and stable hydrodynamic lubrication - essential for wear resistance, smooth engine operation, and long service life.

Big end bearings are central to engine bottom-end integrity. They endure high loads, RPMs, and constant motion. Over time or due to lubrication issues, bearings can wear, lose material, or show surface degradation - leading to increased clearances, knocking noises, reduced oil pressure, and accelerated wear of the crankshaft journal. Replacing worn bearings with OE Match shells during a rebuild restores proper oil clearances and hydrodynamic lubrication, helping protect the crankshaft and rod journals from premature wear while supporting smooth, reliable engine operation.

When to replace:
•  Engine is undergoing rebuild or overhaul
•  Bearing wear, noise, or rod knock detected
•  After lubrication or oil starvation incident
•  During high-mile preventive maintenance
•  When crankshaft journals are within standard size (no undersize needed)

About Connecting Rod

High-Performance Connecting Rods (Con Rods) – Strength, Precision, and Balance for Porsche Engines

Connecting rods — commonly known as con rods — form the vital link between the piston and the crankshaft, converting linear motion into rotational force. In high-performance Porsche engines, con rods endure immense stress, heat, and pressure with every revolution, making their strength, balance, and precision crucial for reliability and performance.

At Design911, we offer a range of precision-engineered connecting rods designed for both classic and modern Porsche engines. Manufactured from motorsport-grade materials, these components deliver exceptional tensile strength, fatigue resistance, and dimensional accuracy — essential for high-RPM operation, rebuilds, and engine tuning projects.

What Do Connecting Rods Do?

Connecting rods are the mechanical bridge between pistons and the crankshaft, transmitting the force generated during combustion into the crank’s rotational motion.

Core Functions:

  • Convert reciprocating motion into rotation, enabling engine power output.
  • Withstand extreme pressure during every combustion cycle.
  • Maintain piston alignment and crankshaft balance at high speeds.
  • Influence engine response and rev characteristics, particularly in performance applications.

Lightweight yet durable connecting rods are critical to maintaining smooth, reliable power delivery across the RPM range.

Why Do Connecting Rods Fail?

Even with Porsche’s engineering precision, connecting rods can degrade or fail due to stress, wear, or improper lubrication — especially under performance driving conditions.

Common Causes of Failure Include:

  • Oil starvation leading to bearing failure or heat damage.
  • Over-revving or detonation causing bending or fatigue cracking.
  • Incorrect torque or clearance during rebuilds.
  • Material fatigue from age, stress, or high-mileage operation.
  • Improper lubrication causing friction wear on big-end bearings.

A failing con rod can result in catastrophic engine failure, making proactive inspection and replacement essential during rebuilds or upgrades.

Why Replace with Performance-Grade Connecting Rods?

Upgrading to high-strength connecting rods ensures your Porsche engine maintains optimal balance, durability, and performance under high stress. Whether restoring a classic flat-six or building a tuned turbocharged powerplant, precision rods provide improved reliability and smoother operation.

Key Benefits:

  • Increased strength and fatigue resistance under high-load conditions.
  • Enhanced engine response through reduced rotational mass.
  • Maintains piston-to-crank alignment for smoother operation.
  • Ideal for rebuilds, tuning, and performance upgrades.
  • Crafted from premium materials such as forged steel, billet alloy, or titanium.
  • Precision-balanced to reduce vibration and ensure even load distribution.

Motorsport-grade connecting rods deliver the perfect balance of strength and agility, ensuring your Porsche engine performs reliably — whether on the track or road.

Highlights:

  • High-performance con rods engineered for strength and endurance.
  • Manufacturer-quality fitment for seamless integration with Porsche engines.
  • Forged and billet designs available for both naturally aspirated and turbocharged models.
  • Lightweight, precision-balanced construction for maximum RPM stability.
  • Perfect for performance builds, rebuilds, and engine restorations.
  • Tested to motorsport standards for strength, fatigue, and dimensional accuracy.
