Essential BMW 325i Engine Internals

Glyco – Glyco Main Bearing Set (Part No.A201049522GLY)

Glyco Main Bearing Set

from

$195.86
Glyco advanced engine bearing technologies withstand heavy loads and cope with the increasingly challenging conditions of modern, environmentally-friendly engines. Glyco is the world’s largest manufacturer of OE-quality bearings. Every year, our engine bearings are fitted on more than 10 million engines around the world – from small bore engines to heavy-duty commercial vehicles and stationary engines. Driven by the need to reduce CO2 emissions, today’s engines extract more power from less fuel. Due to the increased temperature and load, conventional bearings struggle to cope. Thanks to over 100 years of innovation, Glyco provides bearings with advanced metallurgy that can withstand these challenges. Federal-Mogul invented Glyco Sputter Bearings with twice the service life of conventional bearings. Glyco developed G-188, the first intelligent bearing material, and were also first to launch a full lead-free material portfolio. Recent innovations include the highly durable Glyco IROX bearing shells, which address the challenges of hybrid, stop-start and downsized engines.

Product Features:
  • Original Equipment Quality
  • Excellent wear resistance
  • Low propensity to seize
  • Reduction in Friction

Kolbenschmidt – Main Bearing Set (Part No.A20101807058KS)

Main Bearing Set

from

$78.50
KS crankshaft main bearing sets provide maximum load-bearing capacity, anti-seize and low wear and friction. KS main bearing sets are manufactured with aluminum-tin sliding material and the innovative aluminum-zinc-bismuth alloy in which bismuth replaces lead. From the strands continuously cast on site, strip is generated in defined and coordinated rolling and annealing operations for subsequent cladding. The various steel-aluminum composites are finally produced by roll bonding. Innovative coatings also ensure optimal running-in behavior and low-wear continuous running. The spectrum of possible surface coatings at KS Gleitlager extends from galvanic films deposited electro-chemically and sputter layers applied electro-physically in a high vacuum, to synthetic antifriction coatings.

Product Features:
  • Original Equipment Manufacturer
  • Maximum Load-Bearing Capacity
  • Low Wear and Friction

Goetze – Piston Ring Set (Part No.A2050284338GOE)

Piston Ring Set

from

$43.98
Goetze OE piston rings for gasoline and diesel engines, are developed for automobile, light commercial vehicle and heavy-duty applications, come in a wide range of sizes, include the first ring sets introduced for Euro4-compliant engines. The end gap can be a straight cut, angled cut or gas tight type for improved sealing. Radial pressure distribution greatly influences ring performance therefore we modify the pressure distribution according to the individual application. The wear-resistance and running-in behavior of the outer ring surface is defined by selecting from various coating options, which include the high-performance electroplated, thermally sprayed and PVD coatings. Goetze modern oil control rings scrape off oil from the cylinder wall, leaving just the required amount for lubrication. The running surface is the contour of the ring facing the cylinder surface. The objective of this running surface profile is to create a lubrication slot with a hydrodynamic film which the piston ring can slide on without touching the other surface. An optimized asymmetrical-barrelled running surface ensures low lubricant consumption even after a very long running time. Goetze piston rings have anti-scuffing properties that promote smooth engine operation, reduced oil consumption and long engine life. In addition, the Goetze process helps prevent materials from detaching and cracking and aids in environmental protection

Product Features:
  • Maximum durability
  • High wear and corrosion resistance
  • Excellent heat-conducting capacity
  • Optimal fit

Mahle – Piston Ring Set (Part No.A2050284251MAH)

Piston Ring Set

from

$27.45
MAHLE Original piston rings lead the way in ring technology and innovation for the Aftermarket – after all, MAHLE is the largest manufacturer of piston rings in the world. MAHLE Original rings are at the forefront of light vehicle piston ring technology. Extensive OE connections mean that MAHLE Original rings have the technological edge. Things like the CP-20 oil ring, narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings and coated compression rings for diesels all came from the OE. The MAHLE Original performance line proves time and again that it should be the ring of choice under every hood – regardless of the application. Grey cast iron or ductile iron was traditionally the material of choice for automotive applications – today, steel is preferred over iron by more and more engine builders. Steel compression ring technology has been used in heavy-duty applications for over 30 years. That know-how has become essential to the design and engineering of today’s automotive engines. Steel piston rings offer higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still offering a lower ring mass. These factors lead to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and improved blow-by control while still lowering friction.

Product Features:
  • Ease of installation makes them the premier choice for rebuilders everywhere.
  • The CP-20 rings can withstand the harsh operating environments in today’s engines.
  • The CP-20 consists of a barrel-faced top compression ring for better seal and quicker break-in, a reverse torsional twist second ring for better oil control
  • The CP-20 design oil ring that is easier to install
  • Chemically polished for better oil drain-back
  • A 20 degree ear angle to ensure side seal around the ring

Mahle – OE Replacement Piston (Part No.A2039407667MAH)

OE Replacement Piston

from

$244.54
MAHLE Original pistons are OE quality and have many premium OE features. Pistons have to put up with extreme pressures, as their working conditions have become significantly tougher in recent years. Naturally, the demands on pistons have also risen progressively: they must be lighter, must have lower oil consumption and must be absolutely safe and reliable. MAHLE Original pistons are reliable. In many instances, MAHLE is asked to supply the pistons for an OE manufacturer’s high output, premium engines. The Chrysler 2.5L Turbo, Chevrolet 5.7L LT5 (ZRI Corvette), Chevrolet 5.7L LT1 and Chevrolet 4.3L 200HP truck engines all have our pistons. MAHLE’s eutectic (12% silicon) aluminum alloy is performance proven in literally millions of engines around the world including high output diesel engines and Formula One racing.

Product Features:
  • COMPENSATED RING GROOVES assure proper ring loading and oil control.
  • EXPANSION CONTROLLED DESIGNS for small fitting clearances. With the tighter fitting clearances comes reduced engine noise, reduced wear, reduced emissions and improved oil control in the long term.
  • PIN OFFSET for reduced engine noise.

These Bimetal bearings also offer greater wear resistance than the leading competitor’s bi-metal material, as well as greater seizure resistance. Clevite Bimetal bearings feature 100% bored ID’s for precision and surface characteristics and where appropriate – straight shell main bearings utilizing an “umbrella” groove that allows for superior oil control and improved pressure.Clevite® Bimetal engine bearings are of aluminum, tin, silicon Bimetal type of material and construction. These offer the engine rebuilder an Oe type of bearing for engines going into light duty applications. They are only recommended for applications where all engine components have been reconditioned to engine manufacturers original specifications.Bimetal engine bearings are not recommended for Heavy Duty service where heavy demands are placed on the engine or High Performance applications where Clevite TriMetal is still the ultimate performance choice.

Product Features:
  • Original Equipment Manufacturer
  • Maximum Load-Bearing Capacity
