Torque Plate Simulation Honing

When rebuilding an engine, it is essential that a cylinder bore is honed, regardless of whether the engine has been re-bored or not.  Honing a cylinder removes any cylinder markings or minor scratching and creates the perfect bore finish for optimum lubrication for the rings.

In high performance applications or diesel engines, precision measurements are vital due to the extreme operating conditions.  An engine is often honed using a torque plate.  This procedure is carried out in order to simulate normal running conditions within an engine.

A Chev LS1 honed using a torque simulation plate, used to replicate the distortion created when the cylinder head is installed. Main caps are also installed and tensioned.

When a head is bolted to a block, the load created by the tensioning process causes block distortion.  This distortion can alter the geometry of the cylinder.  This means that a block without load will have a slightly different shaped cylinder bore to the same block with load.  Dimensional variations of .003" to .004" have been recorded. Torque plates are designed to the same specifications as the head of that particular application and are bolted to the block with the same tensions used to clamp the head to the block.  By honing a cylinder with the torque plate, you are creating the same conditions in the bore the engine will have under normal operation.  Therefore, the resulting hone will be perfectly round when the engine is assembled.

Creating these ideal conditions whilst honing can create many advantages.  A cylinder with perfect roundness will create more effective cylinder sealing with the rings.  This optimizes lubrication to the cylinder and provides consistent ring wear and rotation.  Performance engines operate under extreme pressures, intense temperatures and high rpm. Similarly, diesel engines also operate under powerful forces. These excessive conditions ultimately contribute to greater potential for damage to occur and severe wear.  Combining torque plate honing with the correct cylinder finish for your application, will ensure your engine has a long life and reaches its power potential.

Galloway engines have torque plates to suit many applications.  For more information, or to find out how we can meet your engine machining requirements, please contact us.

Frequently Asked Questions

How do I know if my engine needs reconditioning?

Tell-tale signs that your engine requires attention are that it has lost performance or efficiency, it blows excessive smoke or it has developed an unusual noise.  However, a vehicle needn't have these symptoms to benefit from a reconditoned engine.  A complete and comprehensive recondition of your engine will increase power, fuel efficiency and extend the life of your vehicle.

Do you remove and refit engines?

Galloway Engines is a precision workshop which deals in machining and reconditioning engines.  This ensures we are specialists in our field and only a quality job of the highest standard will be delivered.  We can arrange engine removal and fitment or contact your regular vehicle servicing centre for this service.

Can I supply my own parts?

Yes. You are quite welcome to supply your own new parts should you have a preference for a particular brand name.  However, our parts prices are very competitive and our high standards ensure that only quality parts are fitted to any job.  We have liaisons with many Australian and international companies allowing us to have access to world-wide sourcing of parts.

Do you offer a warranty?

Any reputable product will come with a warranty as proof of its quality.  Galloway Engines are no exception.  We offer a full warranty on all of our work.  Contact us for more information on the terms and conditions of our warranty.

Why should I use Galloway Engines?

Galloway Engines supply a quality engine which is completely reconditioned to comply with original manufacturers specifications and are in accordance with Australian Standards AS4182 for petrol engines and AS4427 for diesel engines.  Our up-to-date equipment produces quality precision work and our team of specialised technicians are dedicated to detail.  This ensures you are getting the best job possible.

Can you recondition any engine?

Yes. Whether it be a Caterpillar engine from a giant earthmoving machine or a small three cylinder Suzuki engine, we have the equipment to be able to meet your needs.  Contact us to see how we can meet your requirements.

Do you offer engines which suit LPG?

As LPG has different properties to unleaded fuel, an engine can experience problems when converted to LPG.  We can offer options which can enhance the performance and reliability of an LPG engine.  Galloway Engine Reconditioning also stock a range of exchange heads which are modified to run on LPG.  

Do you have EFTPOS?

We have full EFTPOS facilities available and are able to accept payment via Credit or Debit Card.
