Development History

  • After manufacturing, designing and testing hundreds of performance MRB engines, Mark found when stripping these engines after many miles the only thing in common with each engine was the seals were worn out whilst all the performance parts were perfectly alright.
  • This minor failure of seals over many miles lead us to develop these new MRB Viton seals.
 
 

Reasons to Buy

  • Longer lasting.
  • Harder wearing.
  • MRB quality.
 
 

Tips

  • Fit the seal dry on outer edges.
  • Grease or oil inner seal faces before fitting.
  • Oil seal surfaces on crankshaft.
  • Use a crankshaft puller to fit the crankshaft.
  • Spin the crankshaft when drawing into place.
