In addition to their use in road construction and building construction, jack hammers are also used in mining and quarrying operations
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).

Role of Rubber Oil Seals: Versatility and Performance
Aflas is created from fluoroelastomers (FKM), providing the following benefits:
Common causes of oil seal failure
• Rubber torque prevents gear rattling noise
Sealing of lip type seal is normally a result of an interference fit between the flexible sealing element, usually augmented by spring pressure and a shaft. Fluid retention is based on the precise amount of lip contact pressure. In most lip seals, increased fluid pressure in the sealed area causes lip contact pressure on the shaft to increase.
The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
Thoroughly clean the area around the oil seal and check how it is fitted. If you cannot see the outer end of the seal, remove the timing-belt cover or chain cover (not the belt or chain) and possibly the water pump (See Replacing a water pump ) to reveal it. On an engine with a belt-driven overhead camshaft , remove the belt and its drive sprocket .


Auto parts oil seals play a crucial role in the proper functioning and maintenance of vehicle systems. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the integrity and efficiency of various components within the vehicle. From wheel hub oil seals to steering oil seals, these components are essential for the smooth operation and longevity of automotive systems.
Durability is another important factor to consider when choosing a spark plug, and the Spark Plug 794 00082 excels in this area as well. With its robust construction and high-quality materials, this spark plug is designed to withstand the rigors of daily driving and maintain its performance over the long term. This means that you can rely on this spark plug to provide consistent ignition performance, even in the most demanding driving conditions.
