Schaeffler has added the INA-developed aluminium support rocker arm assembly for the Ford Puma diesel engine family to its product line.

This has been developed for the four cylinder 2.2-litre and in the 2.4-litre engines, currently used in the Ford Transit, Fiat Ducato and in the Land Rover Defender. 
 
The aluminium support rocker arm assembly developed by INA has benefits for the valve train. It reduces both, weight and noise of the engine. The rocker arms are mounted securely to the hydraulic tappets and the aluminium support elements by means of retaining clips. Ducts inside the aluminium unit supply oil to hydraulic elements, camshaft bearings and additional pumps. In OEM the complete rocker arm assembly is installed as a single unit.
 
This should also apply to any repair. If any part of the rocker arm assembly is damaged, the vehicle manufacturer recommends replacing it completely. For example, if the individual hydraulic elements are taken out of the locating bore in the aluminium unit for repair, the bore itself might be damaged and can no longer be used. The safest course of action is to follow the OE manufacturer’s suggestion and replace the entire rocker arm assembly.
 
Garages and service centres can order the INA aluminium support rocker arm assembly from any Schaeffler distribution partner. A non-verbal installation guide for professional repair is included with each rocker arm assembly. In addition, exact vehicle applications, original part numbers and cross references are available in all INA catalogue media.
