GM Hydraulic Throwout Bearing Assembly Method
Because bearings are high-precision products, improper assembly can easily cause damage to the bearing grooves and lead to bearing damage. The jeep tj throwout bearing should be assembled with special molds, and should not be knocked at will. Only small circles can be pressed into the shaft, and only large circles can be pressed when pressing large circles. When assembling, air pressure or hydraulic pressure should be used, and the upper and lower die should be horizontal when press-fitting.

Corrugated sheeting, corrugated roof sheets
Corrugated Sheeting
Corrugated is the traditional and familiar S-Rib profile for roofing and cladding applications. It is the oldest and most commonly used roofing profile because of its easy handling and fixing properties and related strength. The S-rib is derived from sinus curve and offers very strong and structural properties.
Structural Guidelines
Corrugated roof sheets are available in a wide range of materials displaying various structural properties. It should be noted that the load span characteristics are only to be used as a broad guideline, as purlin spacing is also dependant on other factors such as the prevailing winds in a particular area, snow during winter periods, the presence of dust and other particles in industrial areas, the type of structure that is being erected, etc. We therefore recommend that an engineer be consulted to determine the purlin spacing for a specific application.
Roof pitch
When using Corrugated, the recommended minimum pitch for roof slopes in excess of 15 m is 12.0° and for slopes less than 15 m is 10°. When Corrugated roof s heets are end-lapped the roof pitch should be taken into account. The minimum end laps for roofs pitches in excess of 15° is 150 mm and for other roofs a minimum of 250 mm is recommended. End laps for side sheeting should be at least 100 mm. It is recommended that end and side laps on low pitch roofs be sealed to ensure water tightness
Accessories are an indispensable part of the proper sandwich panel installation. In krs’s offer there is a wide range of different accessories that together make a whole assembling system. Using the krs’s dedicated flashings guarantees a long life of the building.
Our qualified staff will help you to choose the proper flashings.
Installation accessories fulfill several important functions.
Metal flashings are required not only for improvement of final look of the building, but mainly for covering opened core edges as well as joints with windows, doors etc.
Protection against wind, rain or snow is as important as adding a final touch to the esthetics.
We prepared all of the accessories to fit to the panels both technically and optically.
In krs’ offer we have several installation accessories:
Fasteners (screws, fasteners, rivets, load distributors, etc.)
Sealants (adhesive tapes, sealants, gaskets)
Fasteners with a tapered shank (self-tapping screws)
chipboard screw & particle board screw
Similar to a drywall screw except that it has a thinner shank and provides better resistance to pull-out in particle board, while offset against a lower shear strength. The threads on particle board screws are asymmetrical.
concrete screw& Tapcons & masonry screw & confast screw & blue screw & self-tapping screw & Titen
A stainless or carbon steel screw for fastening wood, metal, or other materials into concrete or masonry. Concrete screws are commonly blue in color, with or without corrosion coating. They may either have a Phillips flat head or a slotted hex washer head. Heads sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw.
deck screw
Similar to drywall screw except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread cutting tip for installation into decking materials. They have bugle heads that allows the screw to depress the wood surface without breaking it.
double ended screw & dowel screw & hanger bolt
Similar to a wood screw but with two pointed ends and no head, used for making hidden joints between two pieces of wood.
A hanger bolt has wood screw threads on one end and machine threads on the other. A hanger bolt is used when it is necessary to fasten a metal part to a wood surface.
drive screw & hammer drive screw
Chiefly used for attaching manufacturers data plates to equipment. Smooth round or mushroom headed with a multi-start thread on the shank, beneath which is reduced diameter shank that acts as a pilot. The screw is fastened by hitting the head with a hammer and is not intended for removal
drywall screw
Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, however it is a versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the grip diameter.
eye screw & screw eye & vine eye
Screw with a looped head. Larger ones are sometimes called lag eye screws. Designed to be used as attachment point, particularly for something that is hung from it. A vine eye (in the UK at least) is similar to a screw eye, except that it has a proportionally longer shank and smaller looped head. As the term suggests vine eyes are often used for attaching wire lines across the surface of buildings so that climbing plants can attach themselves.
