    K447,

    Good point. I just used some old hose I had laying around as well. Definitely doesn't provide a good seal with that hose clamp. I will look around for those at the hardware store and change that out.

    As far as some excess grease still coming out, do you think that is an issue? Once I change clamps, should I try pumping more in? I figured 30 was more than enough.

    What size are those threads on the grease gun hose? I may change to that later..........but I don't feel like taking that seat bracket off again or the electrical box .

    Grease seepage is a bit messy, not really a 'problem..

    I would only be guessing regarding adding more grease. I have no idea how much grease capacity 'room' there was inside the intermediate bearing, nor how much grease you may have put in already.

    Good call. I'm just going to say its good. I know there's more in there than before! LOL. If I change to the grease hose, I just want to be able to adapt whatever thread is on those to the 1/8" NPT fittings I already have.

    Standard US grease gun hose is 1/8" NPT male thread each end.

    Should screw right into your Alemite 1/8" NPT female fitting.

    Thanks K447. My lazy butt went back and verified this in an earlier post you had in this thread. Sorry about that! I think I'm going to change out to a grease gun hose to prevent any leaking. Will have to do the job over, but it should go quicker this time! It's just a pain getting to those bottom 2 bolts on the electrical box.

    I just wanted to alleviate some of the paranoia about "blowing seals". Sure, as a general rule, please slow-down and go-easy when back-pressure builds in the grease gun - its a good indicator the IB housing is full, yet it's not that easy .... in-fact hard to really hurt these seals.

    There are 3 seals total in the housing ... one forward - facing forward, and two aft - facing aft. There is a huge cir-clip fwd, and another aft in the housing, so the seals ain't going anywhere!
    I used the term "facing" deliberately, as the the seal material contacting the shaft has a single-direction relief taper - a quasi "lip" if you will. Supporting the backside of the lip is a typical spiral circle spring to insure even tension as this lip rides the shaft's circumference. (( Keep it clean folks! ))

    Referencing the pics above .... so if you are grease sitting on either side of this seal, you can easily ooze past in one direction, and nearly impossible in the other. Thankfully all seals are therefore facing outward in respect to the IB housing's inner cavity, so over-filling, grease air water can simply slip by the seals outward. And because there is only one seal fwd, that's typically where that excess grease will go - you got it, hits the spinning flange coupler and flung everywhere !

    The reason I'd still "go easy", is if your seals are worn or otherwise slight defective, as it is plausible to rip the lip or unseat the lip's supporting spring behind it, given you really blast a fist-full at once.

    Again ... just pointing this out, so those of you out there are not going too-gingerly on the fist pumps. Give firm squeezes, in fact, it doesn't hurt to slightly over-fill, so the "old" aka possibly contaminated grease can get flushed out - eventually.

    Thank you for pointing that out!
    I suggest you edit your original post to remove reference to tapping the bearing housing, or any of the incorrect fittings so as not to lead anybody else down the wrong path. you have to read carefully to see the one sentence that references the correct fitting, but it's buried in pages of procedure for tapping the housing which is completely unnecessary.

    I have added additional text and clarity to the original posts.

    There is only one post describing the thread tapping procedure, and it and the post prior both now reference the ‘correct’ metric fitting.

    Some people may not have access to metric grease fittings or perhaps would be interested to read how I did the thread tapping.

    I have retained the original text along with the updated info, clearly posted and in bold.

    You are not correct, you are greasing the splines on drive shaft. There a tiny pin hole in mid shaft that rear seal and bearing create cavity so when you pump grease in it.goes through the pin hole and your greasing the shaft splines only. See the hole just in front of my finger, the seal is just bellow the hole and the bearing is just behind my finger, there a grease seal formed between the rubber shaft seal and the bearing adding protection and grease goes through hole and lubricates the splines. This is where there two small o rings in mid shaft sealing grease in those o rings get dry and crack you need to grease it regularly or you have spline wear Some aftermarket mid shafts do not have the hole and there for spline wear is big issue

    ^^^ Can you confirm the part number in your photo? We're trying to get relevant information here, which includes being accurate about specific make & model of this thread's title and categorized section. If it's not related, your absolute assertion of a pin hole existing does no service to other owners of this craft, or others that share the same part : FZR/FZS, FX (all 1800), VX HO, VXS/VXR ranging from year 2008-2020 (present). We simply do not want these owners thinking the splines are getting lubed, when contrary to your post above, they are indeed not.

    Not sure what shaft that (pic) is off of (superjet/blaster maybe, perhaps a 1st gen VX's) . . . but it's not from a GP1800 (aka thread title). There is no such pin hole on the GP1800 mid-shaft. Okay, but let's pretend we wanted to put a hole there ourselves for such purposes ... you can't .... due to the depth/offset of where the splines are recessed deeply into the housing, to get the hole at said seal/void alignment, the hole would end up smack in the middle of one of the machined spline valleys.

    The Service Manual substantiates that the housing (zerk fitting) is designated with grease (A), while the splines are designated with grease (M) - again, there is no hole for these to to cross-contaminate. The zerk provides grease (A) to the housing's bearing, and excess grease pumped into the GP1800 housing results in grease slippage mainly across the fwd seal, some also past the aft seals - yet there are two aft, so not as much. Splines on the GP1800 are greased once, when the pump shaft is being reassembled, and the two o-rings inside the mid-shaft form a tight seal on the drive shaft locking that one-time (M) grease inside along with some trapped air - in fact, it's a big no-no to attempt to completely fill the inside of the mid-shaft solid with grease, else frankly, you simply won't be able to get the shaft inserted.
