This FS01-11-310AL1 crankshaft oil seal is a tailor-made replacement part, specifically for Haima S7 models from 2013 to 2016. It also fits some Mazda cars like the Mazda 323 and Premacy that come with Haima’s 483Q/479Q engines. Its main job? Seal the engine tight to stop oil leaks and keep your engine running smooth as silk!
Made to match the original crankshaft specs of the Haima S7 exactly. If your old oil seal is worn out, just swap it with this FS01-11-310AL1 – no extra tweaks needed, super convenient and time-saving.
It fits like a glove not only on Haima S7’s front-engine, front-wheel-drive manual models but also on Mazda cars sharing the same engine platform.
It’s got a dual-layer design: the inner rubber lip (made of NBR or FKM rubber) locks in oil, while the outer dust lip keeps dirt and debris out – double protection so you can rest easy.
Super tough! It handles extreme engine heat (up to 150°C) and high rotational speeds like a pro, lasting ages without giving up.
Precision-made to snuggle up tight against the crankshaft and engine block, totally putting an end to the hassle and losses from oil leaks.
Crafted with top-notch synthetic rubber and reinforced with a metal frame, so it’s super stable and won’t deform easily.
Awesome corrosion resistance: it stands up to oil erosion, oxidation, and harsh environmental conditions, boasting a long service life.
Strict quality checks during production, plus ISO 9001:2015 international certification – meets global auto industry standards, so FS01-11-310AL1’s quality is totally reliable!
Designed just like the original, so you can pop it into the factory crankshaft housing with standard tools like a torque wrench – cuts down on labor time big time.
That said, we still suggest getting a pro to install it. They’ll make sure it’s aligned right and use the correct sealant, avoiding misalignment or early failure.
Fixes oil leak issues for good: If your car’s leaking oil because the old seal is shot, swapping it with this one fixes the problem instantly, gets your engine back to peak performance, and protects nearby parts from damage.
Super cost-effective: Delivers OEM-level performance but at a way better price – saves you from shelling out big bucks on engine repairs.
Trustworthy as can be: We’ve been exporting auto parts for nearly 20 years, and this product has got tons of great feedback from our global partners – its reputation is rock-solid!

This oil seal’s a total star in the engine’s sealing system—stays rock-solid and seals like a pro, even when the engine’s working its guts out in tough conditions! Let’s dive into its killer highlights one by one:
It’s custom-made for Haima S7’s 1.8T (HM484Q-T) and 2.0L (HM484Q) engines, and it also plays nice with FP series engines from Mazda 323, Premacy, and other models. Its size and structure are tweaked to perfection, so it fits like a dream on the crankshaft’s rear end—no more annoying oil leaks!
Made with fluororubber (FKM), this sealing lip has super strong C-F bonds in its molecules. That means it’s a beast at handling heat—toughs out -30℃ to 200℃ for the long haul, and even cranks through 230℃ for short bursts! It also laughs off oil (hardly swells up in mineral or synthetic lubricants) and chemicals (acids, alkalis, and all sorts of organic solvents can’t touch it). This material keeps the oil seal stable and long-lasting, even when things get hot and pressurized.
Inside, there’s a spring steel skeleton that gives it unshakable support—so it won’t bend or warp, even after running for ages. Plus, it’s got a spring-loaded self-tightening setup (kind of like a fancy patented design!) that automatically fixes any wear and tear. That means it keeps steady sealing pressure, even if the crankshaft wiggles a bit—leaks? Not on its watch!
It uses a double or triple-layer lip design. The inner main lip clings tight to the crankshaft, acting as the first line of defense against leaks. The outer auxiliary lip comes with a dust-proof setup that blocks dust and grime, making the oil seal last way longer. Some similar products even have labyrinth guide ribs or spiral ribs that actively shake off dust—taking dust protection to the next level!
The lip surface might also have a graphite coating or nano-ceramic treatment. This cuts down friction with the crankshaft big time, so there’s way less wear, and no weird creaks or noises. For example, a graphite coating on fluororubber can get the friction coefficient below 0.1, and it also stops the lip from getting stuck or seized up.
Fluororubber doesn’t age poorly in high temps. Even at the engine’s normal working temperature (110-130℃), it stays flexible—no hardening or brittleness that would break the seal. Tests show that this fluororubber oil seal only has less than 20% compression set after running nonstop at 200℃ for 500 hours!
The spring-loaded self-tightening structure plus the flexible fluororubber soaks up engine vibration and the crankshaft’s back-and-forth movement. That stops the sealing surface from popping apart when the engine is under dynamic loads. This is a game-changer for Haima S7’s turbocharged engine, which has huge sudden torque spikes (the 1.8T engine’s max torque is 230N・m)—and this oil seal handles it like a pro!

This oil seal is a total standout in the engine’s sealing system, boasting reliable performance even under harsh operating conditions. Its key highlights boil down to four core strengths:
Perfect Fit & Wide Compatibility: Custom-engineered for Haima S7’s 1.8T and 2.0L engines, it also works with Mazda 323, Premacy, and other models equipped with FP series engines. Precisely optimized dimensions ensure a snug fit and effective oil leak prevention.
Durable Material Build: The fluororubber (FKM) sealing lip excels at withstanding extreme temperatures (-30℃ to 200℃ long-term, 230℃ short-term), oil, and chemicals. A built-in spring steel skeleton provides stable support, while the spring-loaded self-tightening structure compensates for wear to maintain sealing pressure.
Ingenious Durable Design: Multi-layer lips offer dual protection (primary sealing + dust resistance), with some variants featuring dust-shedding ribs for enhanced performance. Wear-resistant treatments (graphite/nano-ceramic coating) reduce friction, minimize wear, and eliminate abnormal noise.
Rugged Environmental Adaptability: It stays flexible at high temperatures (110-130℃ normal operating temp) with minimal deformation, and efficiently absorbs engine vibration and crankshaft movement. This makes it ideal for Haima S7’s turbocharged engine, handling its significant torque fluctuations (230N・m max for 1.8T) effortlessly.
