The PSS Shaft Seal is the number one selling marine mechanical seal
worldwide and is installed as standard equipment by many of the worlds most
reputable boat builders / yards. The PSS Shaft Seal is also recognized as
the premiere retrofit (aftermarket) seal on the world market. Certified by
Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages
and value of installing the PSS as it eliminates the maintenance, constant
adjustment & cost associated with traditional packing type glands. Aside
from these benefits, the PSS Shaft Seal helps to eliminate water in the
bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20mm) to 6" (150mm).

The PSS Shaft Seal is a mechanical face seal that is created between
the flat surfaces of the rotating stainless steel rotor and the stationary
carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft
in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This
compression (pre-load) maintains contact between the faces and allows the
PSS to compensate for the thrust from the propeller. The carbon flange is
bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The
stainless steel collar is sealed to the shaft by two o-rings that are
recessed into the bore of the collar. These o-rings rotate with the shaft
and stainless steel rotor and do not experience wear during operation.


**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.
PYI suggests as preventative maintenance that the PSS bellow be replaced in
six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."

Bellows may need to be more frequently inspected in an environment where
non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.

The Maintenance Kit includes the items you need to properly maintain your
PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings,
five (5) set screws, four (4) new hose clamps and an allen key.

e46 Sedan Black Kidney Grill: Good fit with a better attachment mechanism than stock!
Size: For BMW E46 1998-2001
These kidney grill replacements were for a e46 sedan (323i). They fit really well. They come with a different type of attachment mechanism than other types I've used in the past: These have 'posts' with a slight groove that you gently pry into place against the hood's mounting tabs. It's a solid holding mechanism - much better than the tab-types I've seen in the past. These do not wiggle around, and feel very solid once mounted. They DID require a bit of fitting with a dremel where the hood release latch is mounted to the hood. I had to cut back about half-an-inch of the inner 'shell' of the grill so it didn't interfere with the latch when you pull 'up' on it to release the hood. Based on having an e46 sedan for 16+ years, and having replaced the kidney grills several times, I'm quite fine with a little bit of modification for a good fit. I like these quite a bit better than other aftermarket types, and even the OEM BMW grills. The price is good, and mounting is solid. I liked them so much, I purchased a second set for my son's 323i right after putting them on one of my 323i's. I plan on getting a set for a 325Ci one that car needs replacements.

They fit super snug and the quality is way better than price suggests.
Size: For BMW E46 2002-2005
They came in wrapped very well in foam and bubble wrap. They felt sturdy and the matte finish was satisfactory. They needed quite some pressure to snap in but when they did you could tell they weren’t going anywhere. The fitment is perfect and it looks great. If the stubs in the car where the grille clips attach are in tact you shouldn’t have a problem. Don’t be discouraged by the negative reviews.

Good value for the money
Size: For BMW E46 2002-2005
The matte is flawless and looks pristine & super easy to install. It does fit and it’s a good enough fit for a daily driver; however, it’s not a flawless fit. It’s off by maybe a 1/16th on the inside corners. It’s amazingly close despite the price point…would definitely recommend.

VERY poor materials and fit for E46, WILL FALL OUT
Size: For BMW E46 2002-2005, Size: For BMW E46 2002-2005
This part resembles the original, but not enough. It is both too big AND too small, depending on the dimensions. It's too small from top to bottom, and too big from side to side. The locking tabs don't get close enough to lock (see pics) because there is too little clearance. Viewing from the front, the outer top corner is so far out (see pics) that the most important tab cannot properly lock in, causing the grill to drop out into my hand (or the ground, if I wasn't there to catch it). The grill also is missing some important curves to follow the shape it is supposed to fit into. It also wasn't matte black as ordered. It looks like it was spray-painted, but I can't be sure. it is made of VERY brittle plastic, and the locking tabs are VERY small and flimsy. I wouldn't expect this part to survive a month or two before blowing away in a medium breeze. One positive is that there is a relief cut to allow the hood safety catch handle to move fully upward without interfering with the plastic grille. That one positive has a lot of making up to do, and there's no way it can do it. Add to that that the seller included instructions for a car fifteen years newer than the model advertised on the item page, and we have a complete failure. But don't worry! I'm sure the seller will probably delete the listing and make a new one so they don't have to have this honest review attached to it.

Quality grills for e46 BMW
Size: For BMW E46 2002-2005
No reason to buy replacement grills at the dealer or even at an auto parts store. These are great quality for a fraction of the price...and you get both sides. Highly recommended if you have an e46 and the grill plastic has deteriorated and is loose. These grills are thick and robust. I like them better than the original. Fit is snug but they look great.
