Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Make sure that the starting system is disabled.Note: Tooling (D) provides all the protective covers and plugs for one cylinder. Use these protective covers in order to maximize the protection during these procedures.

Typical Example
Use the proper procedure in order to apply tension to the cylinder head studs. Failure to follow the correct procedure will result in damage to the cylinder head assembly and the cylinder block assembly.
Note: Tooling (A) has a guard that is not used in the photo.
Place pedestals (7) over the cylinder head nuts. These pedestals are a part of Tooling (A).
Place hydraulic cylinders (6) over the pedestals. These cylinders are a part of Tooling (A).
Attach Tooling (B) to Tooling (A).
Install collars (4). Tighten these collars with a ratchet lever (1/2 inch drive). These collars are a part of Tooling (A).
Loosen the collars to 1 1/2 turns.
Personal injury can result from oil under high pressure.DO NOT allow high pressure oil to contact skin.Wear appropriate protective equipment while working with high pressure oil systems.
Note: The stud tensioner tool groups in Tooling (A) require different operating pressure.
Run the pump in Tooling (A) until the operating pressure is registered on the gauge. Note: This procedure may require more pump pressure which will depend on the temperature of the engine.
Use dowel handle (5). Place the dowel handle through the slot in each adapter. Use the handle in order to turn the nut until the nut contacts the collar. This is equivalent to the passing of 12 holes.
Slowly release the hydraulic pressure and remove Tooling (A).
Remove the nuts and washers from the cylinder head studs.
Use the bolts that hold the rocker arm shaft in place. Attach Tooling (C) to the rocker arm support on the cylinder head.
Attach a suitable lifting device to Tooling (C). The weight of the cylinder head is approximately 204 kg (450 lb).
