Seager Engineering

General information

Seager Engineering provide machining services to classic vehicle owners, local motor-trade and industrial/marine companies.

A comprehensive range of specialist engine reconditioning machine tools allows us to provide repairs and standard recon to a very high standard plus complex casting repairs.
Services include:• Re-boring and re-sleeving of cylinder blocks and motorcycle barrels
• Crank grinding up to 60” in length
• Cylinder head/block facing with PCD/CBN tooling
• Valve seat work including lead free inserts
• Various crankshaft repairs
• Aluminium and cast iron welding
• Thread repairs by helicoiling, timesert or custom made
• Bearing housing re-sleeved to original postion and size
• Component supply for all modern leading brand engines
We supply spares for vintage and classic machines and manufacture our own for specialist applications.

We also supply modern and classics motorcycle engine parts. Contact us for more details or go to our online shop.

We have over the years provided industrial component reconditioning at both repair and re-manufactured level.

We can work with companies to provide a remanufactured part on an exchange basis so lead times can be reduced including manufacturing the spares required in small batch quantities.
Component material can be analysed to determine the type and quality so parts can be replicated or improved as required.
Typical components are shafts, bronze bearings, pumps, both water and fuel injection pumps. Contact us for more details

We can offer prototyping machining services
either from scratch using a sketch, drawing
or altered from another part.

Using all our machines we can machine and alter most
components and with our extensive experience and large
engineering contacts most things can be 'schemed' or
adapted/utilised from commercially available components.
We can accept electronic files with drawings such as .iges or .dwg - email us for more information.

Blasting your component to an 'as new' condition.

Whether your component is fragile or robust we can can give a brilliant sheen finish to either ferrous or non-ferrous parts.

This versatile process can give both a decorative finish, clean state and can be economically produced on a wide variety of used and new components.

Ultrasonic Cleaning
Effortlessly cleans places you just can't reach.

Ultrasonic Cleaning is regarded as a way of cleaning components which either have complex drillings or difficult to reach places.

Using soundwaves to cavitate air bubbles in the cleaning fluid, you can clean delicate and complex assemblies effortlesly with virtually no component risk.

Ultrasonic Cleaning
From carburetters to cameras, crankshafts to clock parts, using a wide variety of fluids and temperatures and by adjusting the frequency great results can be achieved.

We have a VIXEN JETWASH 600 Aqueous Hot Wash which is loaded with an applied chemical caustic degreaser which is made intentionally for aluminium.

This cleans carbonised oil and dirt to a bright alloy finish. Stubborn dirt does need agitation but 80% cleaning is achieved within 10-20m cycle times.
It is primarily used as part of the engine reconditioning process, we keep it regularly maintained and also use it for cleaning components and tools etc...

Many materials such as copper, brass, steel and cast iron can be accurately machined and silver soldered together for a stong and reliable joint, eliminating leaks of air/fuel or hydraulic pressure.

SOFT SOLDERING: This process is mainly for small items where heat and distortion are to be kept to a minimum, examples include carbureter parts, decorative brass components, fuel or water pipes.

SILVER SOLDERING: This process is highly underrated and if performed correctly provides an incredibly strong joint. Strict clenliness and joint preparation are essential but many items can be almost invisibly joined. broken/cracked cast iron is one material that responds well to this type of repair.

BRAZING: Used for manufacture and provides an on-surface joint of reasonable strength many components are made by joining parts together and can be repaired by un-fusing, manufacturing a new section and re-joining.

Our MUREX 375 SQUARE WAVE TIG WELDER allows us to weld aluminium castings or fabrications as well as stainless steel, aluminium/phosphor or bronze either in manufacture or repair.

Other applications include stellite hard facing on rockers and other hard wearing parts, please contact for details. It also has a stick welding facility for cast iron, mild steel and stainless. With adjustable foot control for the amps and a fully adjustable current setting all materials can be welded.

Seager Engineering has a wide experience in aluminium castings for classic bikes and cars as well modern cylinder heads.

Components regulary repaired include: Crank-cases, cylinder-heads, gearbox casings, fuel pumps, bronze selector forks, fuel tanks and marine stainless steel fabrications.

Hard facing using stellite is a cost effective way of reclaiming work wear pads and followers, we also have grinding facilities to re-surface back to original.

Stick Welding
We can repair small cast iron parts with ease, but larger cast iron components require a more specialist approach and are best discussed on application. Please forward details for more information.

On-site welding and fabrications can be arranged through one of our engineering partners. Services include hard facing, structural welding and fitting.

MIG Welding
Our MIG welding capacity is mainly aimed at small fabrications and repairs but we can offer larger fabrications and on-site welding thru one of our engineering partners.
