Don't forget to replace O-rings!

I had almost forgotten that these wear out eventually and it was good to find these 3 spares as replacements.

Does not come with the 100% required O-rings. It says it's a replacement kit but the kit is not complete with the required o rings. They are also not stocked in any local parts store (advanced, autozone, etc) so I had to order them and wait.

Worked perfectly but do pay attention to where the original large blue o-ring is on the filter assembly I placed mine too low and wondered why the fuel leaked everywhere I had to take it back off and move the large o-ring up a bit.

I love this kit. I did read the reviews about how there were missing items but I ordered this anyways. I went through the kit as soon as it came in and it had everything except for one missing o-ring. Thankfully my boyfriend had other o-rings from whenever he started stretching his ears. Also we checked the sizes and all seemed accurate except for the 00 which read about a 7/16 instead of a 00. Overall, this is a very great kit especially with the lube that comes with it and i would recommend this kit. Just check to make sure everything is there since this is a fairly large kit and some pieces can be missed.

While purchasing this product, I read some negative reviews about unit not sealing properly on thread of filter and the O ring been squeesed out when installing, I encounter no such trouble.what may has happened to the person that wrote thar review could have been that he only Used one wrench to tighten the brass nut. Be sure to use two wrenches while doing so. The nut that goes to the filter whervthe O ring is placed should be hand tighten plus half turn. after that a wrench should be used to stop that nut from going any farther into the filter and damage the O ring.while using the other wrench to tighten the nut from the water line.

Packaging.... When package arrived, found that O-rings and most of the collets were lost. I have only 3 collets all different size. Where I can order spare collets?

I installed the  o rings that I received  in the mail.  I have a perfectly working faucet again.  My faucet is working like brand new.  I saved a ton from having to hire a plumber.  I am very happy with my purchase and would order again when the need arises. Thank you amazon.

Perfect replacement when your old inners (gears and valve) still work. Used the extra money and replaced some swivel couplings. My kids noticed how much faster the sweep was running. Don't waste money with and inefficient leaky pool sweep, fix it with this. Please note I also had to replace the o ring which was warn out.

This is hardly an exciting product, but it certainly is vital to allow the Osterizers to work. It is just the kind of thing that can get lost, damaged or wear out. If you could not find or damaged the O-Ring, your use of the Osterizer would be over. This saves you.

It is very inexpensive and it came quickly.

A necessary part that needs to be replaced occasionally - it's doing it's job just fine!

Worked well, repaired air leak I was having. Moderately difficult task be patient and take extra care sliding everything back together as not to damage the new o rings. Watch video for instructions on You Tube. Do not forget to get silicon grease

Revised review: I really wanted this to work; so I went back over the Kuryakyn instructions, online videos, etc.  My bad - follow the instructions verbatim regarding the o-ring.  The instructions say to remove the outboard o-ring and not to re-use it.  The instructions do not say to remove the inboard o-ring and discard - but you should.  Keep it greased and the water should stay out!  Do not use the o-rings when installing this part and my comments below become unnecessary.  And if you have a Road Glide Custom - it will fit but there is some extra work involved during the install due to the fairing being mounted to the engine guard.  And I will call Kuryakyn Customer Service and apologize to them.

Original Review: I put this on my Fatboy years ago and love it.  So I decided to buy one for my 2017 Road Glide Special (no lowers).  Sadly I had to return it.  It is a poor design (IMHO) when compared to the original part; there is no provision to retain the o-rings in place.  The original part has a recess on both ends of the hub to capture the o-rings in the proper location, and allow a metal to metal contact when torquing the nut (see picture - HD part is on the left).  PN9670 has flat sides. So the inboard o-ring is crushed up against the brake mounting bracket and the outboard is squeezed between the washer and brake pedal hub.  However - the pivot shaft diameter is significantly less than the ID of the O-ring - so the o-ring can float around and not provide any sealing.
The installation is this: the inboard o-ring sits against the bracket, then PN9670, then the outboard o-ring, then the washer and nut.  Without any provision to keep the o-rings in the proper position, there is not an effective seal to keep water and dirt out (but they did provide a grease fitting).

The included instructions say torque the nut to 15-20 FT/LBS.  But when torque is applied to the nut, you are torquing against the 2 o-rings.  This is not the correct design for use of an o-ring.  There should be enough compression of the o-ring to provide a seal, then the joint should be metal to metal to allow the proper torque to be applied.  That is the way HD designed it.  I considered adding proper washers with a retaining groove machined into 1 face, or a gasket material rather than an o-ring but decided against that option.  This seems it could be a generic problem for other bikes with pedals using this o-ring design.

Secondly - the included instructions for a 2017 Road Glide will not work.  Due the the fairing mount on the engine guards, removing the bottom bolt and loosening the top center bolt will not allow the pedal to be installed.  There is a hard interference between the ears with the exhaust pipe and the pedal with the engine guard.  I had to remove the brake mounting bracket, slide the pedal onto the shaft, then maneuver the parts back into position and fit the master cylinder rod into the ears (yoke).  Thats when I found the problem!
I have used many Kuryakyn parts on my bikes and have always been impressed with their quality, this is my first negative experience.  I called Kuryakyn Customer Service to give them a heads-up before posting this.

When you do a major tune up it is always a good idea to replace these since you will most likely end up removing them if you are doing a timing belt and the valve cover gaskets. I had no issues with deciding which plug to run them from, just make sure you know your firing order!

My 1997 Buick Century was starting to loose coolant, but it took a while to figure
it out. When this gasket starts to go, the coolant runs out the driver side of the engine around the valley where the silicone (and oil pump gear shaft) are, and down the end of the block and hits the ground somewhere close to the firewall.

THIS IS A STANDARD PROBLEM WITH ALL OF THESE V6 ENGINES AND CAN HAPPEN AS EARLY AS 45k MILES.
The only problem I ran into with this fix, was having to remove the fuel rails/injectors to get the power steering pump out of the way which was NEVER called out on any videos or manuals that I reviewed. Also, as soon as you get the lower intake manifold off, plug the holes into the cam compartment with rags or paper towels to stop the junk you will be scraping off from falling into this area.

This is the best gasket set out there, and is the next generation (metal) design and should stop any future leaks if torqued correctly, and even includes the O-ring for the oil pump gear shaft.
I paid $10.00 more from a local retailer, but, when you need it now, you need it now!
If you are losing a little bit of coolant, and just can't keep it topped off, this is probably
your problem, and it is a good idea to get into it, because you could have other problems besides the broken gasket: See my pics, one showing a how much junk builds up on the close out passage, and the other of the actual gasket failure that looks the same in almost every case. (At 48K Miles!)

As part of my Title, I included the line "Keep the O-rings"  the two O-rings I am talking about are to the interface of the two fuel lines that go into the fuel rails. One (gas in)at the fire wall with a short can regulator, and the other toward the front of the car (gas out)with the fuel pressure regulator. If you have a manual (you should) it will say to replace these O-rings; GOOD LUCK WITH THAT ONE! Do not lose these two O-rings, as it is impossible to replace them. (They are not SK18's)

Oh yeah, when you install the lower intake manifold, remember to hook up the main coolant line to the manifold that you had to undo, cause its tons of fun to get it hooked up after you are all done with the fix.

Good quality and a lot less costly. I thought the o-ring was the problem but after replacing that found the internals were worn on the old one. This one fits perfectly.

Good replacements for original rubber o rings. My girlfriend ears were being irritated by the rubber o rings. Almost like an allergic reaction. These fixed that problem. They do seem to fall off sometimes though.

Buy an o-ring set and slip a couple on to tighten!!!!! Solves the only issue and you have useful o-rings for ever for $12. Excellent!
