We specialise in all types of engine re-manufacturing, repair, renovation & motorsport upgrading in and around the Portsmouth area. We also cover Southampton and the remainder of Hampshire. We undertake all aspects of engine reconditioning including cylinder head repair, engine rebuild, head gasket repair, head skimming, cylinder honing & boring, crankshaft grinding and much more.
We deal with all types of engines including Industrial, Agricultural, marine, passenger car, motorcycle and performance race applications. Banda Engineering is a Portsmouth based family run business with over 50 years of experience in the trade. We can carry out most types of machining and supply parts for all types of engines including cars, commercial, plant, motorcycles, scooters and marine.
We will carry out all stages of reconditioning from just machining to supplying parts and fully assembling engines. We can carry out work on any age of engine and we are finding vintage and classic engine work is becoming more popular and in demand.

We have been grinding crankshafts for over 30 years and our engineers have huge experience with all types of crank from motorbikes to marine engines.
The crankshaft is rotating between approximately 1000 - 8000 RPM and over many cycles, the crankshaft journals will become worn.
Regular oil changes will help prevent this wear.
Low oil or poor oil quality will prematurely wear out your crank.
There are also other engine failures that can cause the crankshaft bearings to wear and fail.
Should this happen, we will to polish the crankshaft journals to makes sure that there is a smooth even surface for a sufficient oil film.

We offer a cylinder head skimming service here in portsmouth.
We recommend that the cylinder head is skimmed when the head gasket is replace to ensure you have the perfect surface for the head gasket to seal.
We also calculate the minimum amount that we can take off.
There is a limit that should be observed and we have to consider piston protrusion.
If the distance of the valves is now closer after a cylinder head is skimmed, we can calculate how far the piston rises and make sure that no contact can be made between the valves & pistons.

We can hone your cylinder block so that the correct oil film can be obtained on the cylinders.
This oil film is need to stop unnecssary wear to the piston rings and to create a seal.
If the bore is dirty or worn this will cause oil to pass the rings and reduce performance and allow oil into the combustion area.
If there has been an engine failure where the cylinder bores are damaged we can rebore the block and install oversized pistons to get your engine back up and running.
Some engines, like the Rover K-Series require a wet liner which is a sleeve that instaled in the cylinder block that is replaced with the pistons.

We can test you camshafts to see if they are still within tolerance and see look for any potential camshaft issues.
We can supply & fit new camshafts to your engine if they need replacing due to wear or other engine damage.
The Camshafts are responsible for valve timing and are critical to the safe running of your engine.
We source OEM and branded after market camshafts to ensure your engine is fitted with quality parts.
Rocker Arms are part of the valve and cam train.
Rockers arms may either run on a rocker shaft or the engine could have a roller rocker which is actuated directly by the cam lobe.

We can determine which main bearings your engine will require.
We can source oversized bearings if the crank is to be ground.
The main bearings sit on the inline journals of the crankshaft.
Main bearings commonly have a oil groove through the centre and oil holes.
This is not true for all engine.
Some main bearings have a flanged pair meaning the engine does not require thrust washers.
This flange determines the amount of end float tolerance for the crankshaft.
These bearings are located on the offset journals of the crank and will have the "big end" of the conrod attached to them.
