What happens to the bikes now they have been seized?

Are you like me and millions of other people thought that we had an elected conservative government to run the country for us? WRONG! We have 3 unelected supreme court judges telling our government what they can and cannot do and before today I had never even heard of them.

Has anyone got a small workshop to rent out, 500 sq/ft or more? We mainly repair large hydraulic cutters. In the Chesterfield or Mansfield area. Thanks. George.

There are many road sweeper manufacturers that use the VM diesel engine to power either the donkey engine or as the prime power plant. Manufacturers such as Scarab, Schmidt, Azura, Bucher and Green Machine all use VM industrial diesel engines because of their low power to weight ratio, low noise levels and good fuel consumption along with uncomplicated designs. This particular sweeper was in for a turbo charger repair.

These are two VM Mercruiser 220hp diesel engines awaiting to be dismantled to rectify damage caused by water ingress when the boat sunk in the harbour. They will both require stripping down to a bare cylinder block to check for corrosion and any wear.

After dismantling and rectifying the damage, the engine on the left was found to have been overheated due to a leaking water pump. This has lead to a low coolant situation which allowed the engine to over heat which then caused damage to the cylinder heads. The engine was sent to the VM Diesel Specialists in a partly dismantled state. We receive almost as many VM engines which have been partly dismantled as we do complete VM engines.

The engine on the right has a broken crankshaft due to a faulty crankshaft torsional vibration damper.

We have done many different repairs to the VM marine engines particularly of this type. These include crankshaft replacement, damage caused by inlet and exhaust valve breakage, cracking of cylinder heads due to the engines being allowed to run with a low coolant level due to leak of hoses and water pump, turbo replacements and porous cylinder liners. We very often find that wear is not a big problem and we usually replace just the damage components and this keeps down the overall cost of the repair. It also proves the longevity of the VM marine diesel engine.

This is a typical VM CRD 2.5 London Taxi TX4 engine, awaiting strip down and examination to asses the reason for crankshaft seizure. Failure of the main bearings and surface cracking (fissures) of the crankshaft journals are common.

After dismantling this VM engine we discovered that the crankshaft had been starved of oil causing bearing failure and server wear to the main bearing journals. The crankshaft had to be replaced with a new one as the wear was more than the permissible amount allowed by VM Motori.

Modern synthetic oils very often allow high mileages to be covered with minimal wear, this being testament to modern lubricating oil engineering and proves the longevity of VM diesel engines, assuming that the owner ensures that the correct amount of oil is kept in the sump.
