IMS Tools

Precision IMS Tools for Safe, Accurate & Professional Porsche Engine Rebuilds

Intermediate Shaft (IMS) tools are essential for servicing, removing and installing the IMS bearing used in various Porsche flat-six engines—most notably the M96 and M97. These tools ensure the job is performed safely, accurately and without causing damage to the crankcase, timing components or bearing carrier. Whether you're rebuilding an engine, replacing a worn IMS bearing or upgrading to a performance alternative, dedicated IMS tools are vital for achieving professional-grade results.

Designed for both independent technicians and committed DIY engine builders, IMS tools take the guesswork out of one of the most delicate operations in Porsche engine maintenance.

What IMS Tools Do

IMS tools support precise and controlled handling of the intermediate shaft system by:

• Safely removing the IMS bearing without damaging surrounding components
  
• Positioning and installing new bearings with perfect alignment
  
• Maintaining correct tension on the intermediate shaft during service
  
• Preventing timing chain disruption during bearing replacement
  
• Supporting full engine teardown procedures for rebuilds
  
• Ensuring correct torque and seating of critical components

These tools make IMS servicing significantly more reliable and controlled than general-purpose alternatives.

Why IMS Components Commonly Fail

IMS bearing failure is a known issue on certain Porsche engines due to design limitations, lubrication challenges and age-related wear. Common causes include:

• Insufficient lubrication of the bearing throughout its lifespan
  
• Age and mileage-related fatigue accelerating wear
  
• Moisture ingress causing corrosion inside the bearing
  
• High-load driving stressing the bearing and shaft
  
• Long oil change intervals allowing contamination to build up
  
• Degraded bearing seals restricting proper lubrication flow

Symptoms include metal debris in the oil filter, unusual engine noise, timing issues or catastrophic engine failure if left unaddressed.

Why IMS Tools Are Necessary for Replacement or Upgrade

Replacing the IMS bearing is a delicate procedure requiring specialised equipment. Using a precision-engineered tool set designed to match original alignment and service specifications ensures:

• Safe bearing removal with no crankcase damage
• Correct alignment for new bearing installation
• Reduced risk of chain tension loss or timing shift
• Professional-level accuracy for rebuilds and upgrades
• Compatibility with single-row, dual-row and upgraded IMS kits
• Faster, cleaner and safer servicing

Proper IMS tools protect both the engine and the technician by ensuring accuracy at every step.
