Crankshaft Balancing
Crankshaft balancing and related rotating assembly support for engine rebuilds, specialist repairs and performance applications. Apexx Engines advises based on the crankshaft condition, engine use, associated components and the customer’s repair route.
What is crankshaft balancing?
Crankshaft balancing is the process of checking and correcting the balance of the crankshaft or rotating assembly so the engine can run more smoothly and reliably. It is often considered during engine rebuilds, performance builds or when related components have been changed, machined or repaired.
Who this service is suitable for
Apexx Engines gives practical advice before work starts, because the right repair depends on the engine, the fault, the condition of the parts and the customer’s intended use.
Engine rebuilds
Useful when rebuilding an engine and checking the condition of the crankshaft, bearings, flywheel and related rotating components.
Performance applications
Recommended for specialist or modified engines where smooth operation and rotating assembly control are especially important.
Machining after damage
May be relevant after crankshaft grinding, replacement, flywheel changes or internal engine damage.
What the work may include
Balancing is part of a wider inspection-led approach. Depending on the engine and component condition, related machining or replacement may be required before balancing makes sense.
- Crankshaft condition review and advice
- Assessment of related rotating assembly components where applicable
- Balancing guidance for rebuild or performance use
- Advice where crankshaft grinding, polishing or replacement is required first
- Flywheel and clutch-related considerations where relevant
- Trade support for garages and engine builders across the UK

Workshop work
Approved machining, reconditioning or replacement work is carried out to suit the engine and the agreed repair route.
Final guidance
We explain what has been done, any related recommendations and the next steps for refitting, collection or delivery.
Crankshaft machining and balancing examples
The images show crankshaft machining examples. Balancing decisions depend on the crankshaft, flywheel, clutch assembly, pulley, engine design and whether the work is for a standard repair or specialist build.

Frequently asked questions about crankshaft balancing
When should a crankshaft be balanced?
It is commonly considered during rebuilds, performance builds or when major rotating assembly components have been changed, repaired or machined.
Is balancing needed on every standard engine repair?
Not always. Some repairs do not require balancing, while others benefit from it depending on the parts involved and the intended use of the engine.
Can balancing fix a damaged crankshaft?
No. If the crankshaft is worn, cracked or damaged, it may need inspection, grinding, polishing or replacement before balancing is considered.
Do you support trade customers?
Yes. Garages, engine builders and trade customers across the UK can contact Apexx Engines for crankshaft and rotating assembly support.
What parts may be needed for balancing?
This depends on the job, but it may involve the crankshaft and related rotating parts such as flywheel, clutch assembly, pulley or other components depending on the engine.
