2.1 Bearing types and names
Plain bearing shells
Plain bearing shells are used for bothconrod bearings and main bearings.They are mostly designed as thin-walled composite bearing shells.Bearings made of two materials havea steel back onto which the bearingmetal, typically aluminium with tinand copper additives, is plated. Inthe case of bearings made of threematerials, the bearing metal is copperwith additives of lead and tin castonto the steel back or applied by thesinter-rolling-sinter method. A nickeldam (diffusion seal) separates the
bearing metal and the galvanicsliding layer.

2. Product information
Plain bearings are an importantcomponent of internal combustionengines.The development of plain bearings
is therefore closely linked with enginedevelopment. Today, the complexrequirements and increased stressesimposed on the bearings of themoving engine parts, such as crank-shafts, conrods, tappets and cam-shaft generally call for the use ofmaterials that are carefully tuned tothe respective application. The largenumber of proven material combina-tions available meanwhile enablesthe design engineer to select theoptimally suited bearing system.

Spreading for easier assembly
The bearing shell is larger than thediameter of the housing holder(pretention). During assembly, thisprovides a good contact with thebore and prevents drop-out or twist.
Press fit by crush height
The circumferential length of thebearing shells is larger than that ofthe bore. On assembly, this bearinglength is reduced by elasticdeformation. The resulting stressgives the press fit which ensures
correct location of the bearing.
Oil groove
Wall thickness Joint bush length
Oil distributing pocket
BushesWith few exceptions, thin-walledsteel composite bushes are used asconrod, camshaft or rocker armbushes. Blanks are punched out fromcoated band steel, which are alreadyprovided with oil holes, oil grooves,oil distribution pockets or locationgrooves. These blanks are thenrolled to form bushes. Grooves andholes may become deformed in theprocess. Both butted and locked
joints are possible.
Bearing shells without locking lugsThe locking lugs on the bearing shellsare used to make manual installationeasier. The lugs are an obstructionwhen assembling engines mechani-cally. For this reason, various bearingshells for new engines are no longer
produced with locking lugs.

Thrust washers
Thrust washers in conjunction withplain bearing shells are a substitutefor flanged bearings in the engine.The axial guidance of the crankshaftis in this case performed by the thrust
washers. Crankcases are specificallyconfigured to accommodate thrustwashers. The reliable guidance atthe outside diameter of the thrustwashers and rotational lock must beensured.This is why housings which aredesigned for the installation offlanged bearings cannot be fittedwith thrust washers.
In some cases it would theoreticallybe possible to equip engines origi-nally fitted with thrust washers, withflanged bearings when recondition-ing. In practice, however, thrust
washers have to be refi
tted! This isthe only way to ensure the optimumcondition with respect to dimensions(bearing face) and material. Thrustwashers are not included in the mainbearing set. They have to be orderedseparately!
Oil groove Locking lug
Flanged bearing shells
Flanged bearing shells are respon-sible for the axial guidance of thecrankshaft in the crank drive bearingsystem. The flanges of these bearingsare ready for assembly and must notbe remachined. Exceptions are clearlymarked in the catalogue.Depending on the engine design, one
or two flanged bearing shells areinstalled.

2.3 High-performance bearings(HGL) - Sputter
Enhanced engine performance callsfor materials of significantlyincreased fatigue strength, lowerwear rate in mixed friction operation
and good corrosion resistance atelevated temperatures, especiallyfor conrod bearings. This complexrequirements profile is met usingphysical vapor deposition (PVD).Under high vacuum, extremely fineparticles are beaten out of a dis-penser. By means of electromagneticfields, they are uniformly applied tothe part to be coated. These magn-etron layers distinguish themselvesby extremely fine distribution of theindividual microstructure compo-nents. The basis of this design is thewellknown composite bearing madeof three materials. The basic designhas been retained. The galvanic sli-ding layer is replaced by a sputteredsliding layer.
2.4 Repair steps
KS offers plain bearings in standarddimensions (STD) and undersizedgrades. We recommend only to use
undersize grades which are alsoemployed by the engine manufac-
turer. The use of larger undersizestages will increase the risk ofengine failure (e.g. shaft rupture),
so that we cannot accept liability forthe installation of such bearings.
Sputtered bearing shells are prima-rily used on the pressure side ofbearings. The opposing shells areconventional two or three-materialbearings. In conrod bearings, thesputter bearing is normally used onthe rod side (top) and in main bea-rings on the cover side (bottom). Forthe main bearing, the lower half issputtered. The correct installationposition of the sputtered bearing
shell is a prerequisite for satisfac-tory operation. To this end, thearrow direction in column 1 in theProduct Program of the cataloguemust always be observed.KS sputter bearings are markedsputter on the back.

3. Assembly of plain bearings Step by step
3.1 Preparation
The tightening specification must be observed for everymachining and measurement process. Two measurements
are necessary as shown in the diagram:1. Measuring the support bearing dimension
(without bearing shells).
Note:Observe manufacturers specification ifconnecting rods have cracked!
2. Messung mit eingesetzten Lagerschalen.
Average the dimensions A and B and compare this withdimension C.The result shows if the bearing is round. If a differencebetween values A and B is found, a cap offset of half thedifference is indicated.

Admissible deviations:
Total concentricity of all bearingcounter bores max. 0,02 mm
Concentricity between adjacentbearing counter bores max. 0,01 mm
These tolerances are guide values unless themanufacturer specifies different data.
For the bore dimensions, the tolerances stated in theCatalogue shall apply.
Permissible taper and roundness:

During the crankshaft reconditioning, several crack checks are necessary, in each case after aligning, harden-ing, grinding!
3.2 Assembly
Final inspection of every crankshaftFor the shaft diameter, the tolerancesindicated in the catalogue shall apply.Individual checking for compliancewith the roundness and parallelismtolerances.Permissible out of round up to aquarter of the shaft tolerance.
Maximum values for tapered, convexor concave ground shafts:
Width (mm) Tolerance (m)
up to 30 3above 30 to 50 5above 50 7
Check: Inspect the crankshaftfor concentricity
It is necessary to carry out a concen-tricity inspection on every recondi-tioned crankshaft, especially afterrehardening. The concentricity ismeasured with support at the outermain bearing journals.
Permissible misalignment of mainbearing pins:
Adjacent journal 0,005 mmTotal 0,01 mm
These tolerances are guide values,unless the manufacturer has speci-fied different data.
Check: radius
The radius must be within the manu-facturers specification. Crankshaftfracture is caused by too small radius.With radius hardened bearing jour-nals, particular attention should be
paid to the maintenance of surfacequality and shape tolerance.
Measure radius
If the correct radius gauge is selected,there must be no visible clearancegap.

Final check: Are the bolts o.k.?
Bolts tightened by torque and anglecan become permanently deformed.If they reach a maximum length orminimum diameter, they must be
replaced. This also holds true formechanically damaged bolts.
Check: Is this the correct bearing?
Make a comparison with the strippedbearing. In this way you can confirmthat your selection from the KS
Catalogue was correct.
That fits: Lug in groove
With this assembly aid, the bearingshell is correctly located.
Selection:Only with the KS Catalogue
KS supplies the bearing shells ready
to fit, whatever the undersize grade.The bearings must not beremachined, unless otherwisespecified in the Catalogue.
Still hard? Inductiveor flame hardened shafts?
Sufficient hardness depth is availableon crankshafts to enable grinding toall undersize grades withoutrehardening, unless the journal has
been softened by overheating.Nitrided shafts must, however,always be retreated.

Keep it clean: Oiling the shells
Use an oil can. A brush may transferdirt particles from the oil container.
Make it safe: Tighten all parts
Strictly follow the tightening specifi-cations. This is important to obtainthe required press fit, giving firmlocation and correct clearance.

KS Plastic Gauge
Countdown to startAll engine components must besufficiently lubricated. Partic-ularly with newly assembledengines, the oil requires sometime to reach all the bearingsfrom the sump. The danger ofpremature damage due to dryrun is high. This can be preven-ted by pressurizing the com-plete oil network.
KS Plastic Gauge plain bearingmeasuring tape
Enables swift and accurate checkingof the bearing clearance on cross-divided plain bearings. It is espe-cially well suited for checking the
clearance of crankshaft main bear-ings, conrod bearings and camshaftbearings on the engines of passen-ger cars and commercial vehicles.
KS Plastic Gauge is a thin, calibra-ted plastic strip which is insertedinto the oil-free bearing position tomeasure the bearing clearance.When the bearing cap is tightened,the width of the strip is contracted.After loosening and removing thebearing cap, the resulting width of
the plastic strip and consequentlythe bearing clearance can be deter-mined with the aid of the enclosedreference scale.
The bearing clearance can be readin mm and inch.
