1 Greases Product Description Choosing the right grease The correct choice of grease is a critical feature in cost effective lubrication. Here is a set of useful recommendations for common grease applications to guide your choice. Ball Joints It is preferable to grease more frequently rather than rely on so-called factoryfilled long or extended life greases. Use a No. 2 lithium or lithium complex grease such a Castrol EPL2, APX T, LMM or SBX 2 Grease. All will permit extended service intervals should they be required. Wheel Bearings The wide use of disc brakes calls for greases with greater resistance to bleed, particularly in heavier vehicles and under racing conditions. For such applications we recommend Castrol HTB Grease E (bentone based) or Castrol APX T Grease (Lithium complex) which can be used at working temperatures above C. For frequency of repacking wheel bearings, refer to the motor manufacturer's recommendations. Note that the style of driving, wheel balance and different road surfaces can have a significant effect on the life of the grease. Do not mix greases (see page 2). Universal Joints The design of these vary, as does the lubricant and method of application. We recommend Castrol EPL2 or APX T Grease (Lithium Complex) for best results. Shackles Castrol EPL2 Grease is generally applicable to all types, EXCEPT those with rubber bushes and those which do not require lubrication. Where shackles are subjected to severe vibration such as rough roads, use Castrol SBX2. B1158/93/4 replaces B744/90/Ind8

2 Steering Boxes Follow manufacturer recommendations. If the steering box is grease lubricated use Castrol EPL0 or SL Heavy Grease. Starters, Generators and Distributors Follow manufacturer recommendations as bearings are often packed for life with a specialty grease. If repacking is required we recommend Castrol EPL2 or APX T Grease. Brakes and Clutch Hydraulic Mechanisms These systems generally employ rubber washers and o-rings. As even small quantities of mineral oil on rubber can cause deterioration, do not use a conventional mineral oil based grease. If metal components periodically in contact with fluid require a lubricant, use only a grease specially designed for these components, such as Castrol GRR (B) Grease. Boating We recommend Castrol Marine Grease or Castrol AP3 Grease for boat trailer bearings. Owners must recognise that the entry of water into bearings causes rust and wear. We recommend cleaning and packing of bearings at least every 6 months. NO GREASE CAN COMPENSATE FOR INADEQUATE MAINTENANCE. High Impact Surfaces The pivot pins used, for example on the bucket control arms of front end loaders are subject to high shock load conditions. To prevent excessive wear we recommend Castrol SBX2 or BMX2 Grease. Constant Velocity Joints Constant velocity joints are usually used on front wheel drive cars, some 4 wheel drives and rear wheel drive cars with independent rear suspension. Our prime recommendation for constant velocity joints is Castrol SBX2, Castrol BMX2, Castrol LMM and Agri Bortax may also be used. Virtually all manufacturers recommend grease containing solid lubricants Castrol SBX 2 offers the best combination of adhesiveness, base oil viscosity, melting point, extreme pressure and antiwear additives.

3 Note: When repacking bearings, completely remove all old grease and wash the bearings in solvent and air dry before applying a new grease. NEVER mix grease of different types as they can react physically, lose their structure and not lubricate effectively. Product Description Lithium Soap Base Castrol LM Grease: A multipurpose high melting point, water resistant grease suitable for all automotive, agricultural, marine and industrial applications specifying and NLGI #2 consistency lithium grease. Castrol AP3 Grease: A universal type medium consistency grease containing oxidation and corrosion inhibitors used mainly for ball and roller bearings operating at high temperatures. Recommended for wheel bearings fitted to boat trailers. Castrol EPL Grease: A range of multipurpose extreme pressure greases displaying both high melting point and water resistant characteristics Suitable for many grease applications and particularly under high load and high temperature conditions where unfortified lithium soap base grease is unsuitable Castrol LMM Grease: A special high temperature heavy duty grease containing extreme pressure additives and molybdenum disulphide. Particularly suited when antiseize properties are required and residual dry film lubrication characteristics are required. Moly content is 3%

4 Castrol CPX Grease: Recommended for spindle lubrication of cotton and corn pickers where grease lubrication is required. It is fortified with corrosion inhibitors and antiwear agents for improved protection of lubricated components. Semi-Fluid * *Modified Cone ASTM D217 Calcium Soap Base Castrol WR Grease: A general purpose grease for pressure gun and grease cup application. The water resistant properties enable CASTROL WR GREASE to be used in underwater applications such as stern tube glands. Suitable for ball and roller bearings operating at high speeds. Castrol TCX Grease: Used for general lubrication of track roller mechanisms where an adhesive grease is required. Castrol PH Grease: Used for auto body hardware, including door catches, boot and bonnet control mechanisms Complex Base Greases Aluminium Complex Castrol FN (EP) Grease: A fine white grease for food processing and packaging plants. It has a high melting point with water resistance and EP properties for difficult applications. Has DPI A rating. It shows outstanding water and steam resistance and is the preferred product for the wettest and most critical applications (Typical) Lithium Complex

5 Castrol APX T Grease: The thicker in APX T grease yields a drop point of C minimum which is higher than conventional lithium greases of around C. Castrol APX T grease also offers improved performance and low operating temperatures down to C compared to conventional lithium greases which are normally only suitable down to 0 0 C The chemical composition of complex soap type greases such as Castrol APX T, provides improved oxidation stability and base oil retention, compared to conventional lithium type greases. These properties are of particular benefit in high speed tapered bearing applications and in applications where parts are placed into long term storage. Abattoirs, food processing, freezer plants, food packaging where Castrol APX T does not come in direct contact with food. Vehicle greasing including wheel bearings of conventional and disc brakes. Plant and equipment operating in extremes of temperature. Castrol SBX 2 Grease: A smooth lithium complex grease of a No.2 consistency. The product contains solids in the form of graphite and molybdenum disulphide and is primarily designed to meet the SKF requirements for sugar mill roller bearing grease

6 Castrol SBX2 Grease (cont) The product has a unique make-up of an extreme pressure additive, solid lubricants and an effective corrosion inhibitor blended into a high viscosity base oil. This makes it highly suitable for low speed bearing applications and some open gear applications. The product is capable of operating up to C and has a load carrying capacity exceeding 800kg under the 4 Ball Weld Load test. Castrol XTG 1 Grease: A smooth, black, tacky lithium complex grease of No. 1 consistency, with excellent load carrying ability and adhesive properties.

9 Health, Safety & Environment Castrol Greases is considered non-hazardous according to Worksafe. However, in line with safe handling practices, it is recommended that the handling instructions outlined in the Castrol Material Safety Data Sheet be followed. Spillage Small: Soak up using an inert mineral adsorbent such as Castrol Diatomaceous Earth and dispose of in the appropriate manner. Large: Corrective action usually dictated by individual company safety procedures. Immediate containment and subsequent removal is essential. Disposal: Oily materials must not be allowed to enter groundwater, watercourses, sewerage or drainage systems. Refer to local Waste Disposal Authority for legal requirements. Product Removal Bare Metal Surfaces: Hand Cleaning: Other Surfaces: Remove with Castrol solvent cleaners or water based degreasers. Use any of the Castrol range of hand cleaners, e.g. CareClean Plus.
