BMW Drive Belts & V-Belts for BMW X Series E84 (2013-2015)

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

It is a well-known issue on the BMW N54/55 platforms that your serpentine belt can fail for various reasons. When this happens, there is a high chance of the belt getting sucked behind the front damper pulley and then being pushed past the crank seal into your oil pan. From there it can get sucked into the oil pick up causing total engine failure. Even if you do not lose the engine, it is a COSTLY repair to remove the sub-frame and drop the oil pan to remove the belt. The best way to combat this is to watch for oil leaks and keep up on your maintenance. BUT, even with those preventative measures, pre-mature belt failure can occur. This crank seal guard installs over your front crank seal and will keep the belt from being sucked in if a belt failure does occur. This is a cheap way to ensure you do not end up having to replace your motor from oil starvation due to an ingested belt. Vargas' seal is different from those already on market in two major ways. Firstly, it is not offensively priced. Secondly, it is 100% billet with no welds on the tabs to break, no cheap bent thin steel pieces. 100% Billet 6061-T6 aluminum, anodized black for long-term corrosion resistance. Crank Seal Guard includes: One VTT Billet N54/55 Crank Seal Guard Two extended 12.9 Grade bolts, and two stainless washers We highly recommend you install WITH a crank bolt capture at the same time, as you have to remove the damper anyway. Then you will get the benefit of helping eliminate the dreaded spun crank hub and the crank seal issue

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

Anyone with a modified N55/S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the N55/S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Included in this kit is MMR's T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. *Installation recommended by a professional shop or technician.
