Problem: Casing crack are usually caused when cooling water is allowed to freeze, but can also be caused by impacts and by over tightening the mounting bolts, thereby restricting expansion. Cracks in cast iron can mean either an expensive repair or more likely, the renewal of the whole component, since cast iron is so difficult to successfully weld.
Belzona Solution: Belzona 1000 Series Metallic Polymers provide a cost effective, permanent repair alternative for cracks, leaking or plugs and porous castings. Working procedures and product options can be obtained from your local Authorized Belzona Distributor.
REBUILDING STRIPPED HEADS
Problem: Damage to threads is a common problem which if repaired conventionally can lead to an expensive repair bill and result in odd sized bolts having to be used.
Belzona Solution: Belzona 1000 Series Metallic Polymers can provide a quick long-term solution to the problem which allows the original bolt to be used. Working procedures and product options can be obtained from your local Authorized Belzona Distributor.
Reseat and mount bearing shells
Problem: Engine Main Bearing seats can wear oversize due to movement and vibration of the bearing shells causing fretting. Conventional repair could involve an expensive welding process, which is not guaranteed to solve the problem, and could in fact make the situation worse by causing distortion and stress with the entablature.
Belzona Solution: Belzona 1000 Series Metallic Polymers ensure reliable long-term alternatives which do not induce detrimental stresses into the entablature of the engine. Working procedures and product options can be obtained from your local Authorized Belzona Distributor.

COOLING SYSTEMS
Reseat cylinder liners
Problem: Liner seats become worn due to fretting and vibration leading to loss of compression and/or cooling water. Conventional repair would normally require that the engine block must be machined and either a new custom line manufactured or metallic shims used to seal the original.
Belzona Solution: Belzona 1000 Series Metallic Polymers offer a tried and tested alternative which enables the original liner size to be used and reseated without the requirement for machining or expensive custom parts.

Reform o-ring grooves
Problem: The liner '0' ring seal grooves suffer from erosion-corrosion making it ever more difficult for the seals to prevent cooling water contamination of the lubricating oil.
Belzona Solution: Belzona 1000 Series Metallic Polymers do not corrode and thus provide the ideal situation to this problem.
Rebuild water passages and ports
Problem: Water passages and ports suffer from erosion-corrosion and as a result, this can lead to water cooling leakage or short circuit.
Conventional solutions would involve hot welding and machining processes and ultimately require replacement of the component.
Belzona Solution: Belzona 1000 Series Metallic Polymers offer cold cured alternatives that give full erosion-corrosion protection for a fraction of the cost of conventional repair.
Seal leaking hoses and pipes.
Repair erosion and cavitations damage.
Rebuild and coat water pumps.
AUXILIARY SYSTEMS
Repair cracked battery cases
Reseat loose battery posts
Problem: Battery cases and posts often become damaged due to impact and vibration. The only real conventional alternative would be to replace the item.
Belzona Solution: Belzona 1000 Series Polymers, which are electrically neutral and resistant to the acids used within these components, offer reliable, long-term repair solutions thus extending the working life of the equipment.
Rebuild alternator casings
Problem: Alternator casings can become cracked and corroded due to moisture and vibration. Since they are normally manufactured from aluminum alloys, the only real conventional repair would be to replace the item.
Solution: Belzona 1000 Series Metallic Polymers have the ability to bond to any metallic substrate, and since they are electrically neutral and non-corroding, provide a cost-effective alternative to replacement.
Repair leaking fuel tanks
Problem: Vehicle fuel tanks often become damaged due to impact, collisions or corrosion. A conventional repair would necessitate the removal of the tank and involve a time consuming, gas freeing procedure, followed by conventional welding techniques.
Belzona Solution: Belzona 1000 Series Metallic Polymers are completely resistant to all fuel oils and as such, can provide an inexpensive cold cure repair which can often be carried out in-situ, thus avoid the need for removal of the tank and expensive and time consuming gas freeing and welding processes.
Repair and protect battery trays against corrosion
MOUNTINGS
Shimming and resurfacing for auxiliary equipment
Problem: Leakage between closely mated metallic surfaces can often occur due to corrosion or distortion of one or both of the faces due to heat.
Conventional repair would involve machining one or both of the faces, which would then normally be re-mated using a conventional gasket or liquid compound to provide a gas tight seal.
Belzona Solution: Belzona 1000 Series Metallic Polymers, having a unique, hi-build gap filling capability, can provide a simple cold curing alternative to conventional repair.
Casting and repairing flexible mountings
Problem: The rubber component of flexible and vibration mountings very often become detached from the metallic carrier due to excessive movement, heat or the general deterioration of the rubber component. Conventional repair would always mean the renewal of the whole component.
Belzona Solution: Belzona 2000 Series Elastomers provide a cost effective alternative to either re-bond the rubber component to the metallic carrier or, using casting or molding techniques, manufacture a complete new part.
Working procedures and product recommendations for this innovated Belzona application can be obtained from your local Authorized Belzona Distributor.
Seal leaks in mufflers
Problem: Exhaust systems and mufflers often spring leaks at seal areas due to corrosion and expansion/contraction, leading to pollution of the environment due to escaped exhaust gases and in some cases, noise pollution. Conventional repair would normally mean replacement of the component.
Belzona Solution: Belzona 1000 Series Metallic Polymers can provide either long term or temporary repair dependent on the leak location and the repair can be done in-situ thus reducing the downtime of the vehicle.
