Final Drive O-ring and Lube Questions

Postby patbrandon1 » Thu Nov 29, 2012 9:56 pm



Upon removal of the final drive of my 82 GL1100 Interstate to put a new tire on, I found that the o-ring on it had been pinched, apparently during the last install. I have looked around to find out the size of it to replace it, but have not had much luck. Anybody know what size it is? Also what lubricates the drive shaft, and what lube is used in the grease zerk?


In the first photo, (that I borrowed from WingAdmin) there are arrows pointing to what I am inquiring about

In the second photo, this is a parts diagram from an on line parts dealer, but they no longer ship the o-ring. I am not sure if I am pointing at the right part, but I think so. The parts list names this as size 60.5X2.4 o-ring. But it doesn't say it is flat on the inside, it just calls it an o-ring. Would just an o-ring work?

Ta.Da.

Looks like you need an oil strainer o-ring for a Suzuki EN125. Most vendors appear to be UK based.

O-RING size is 57 X 4.3 mm - Honda Powersports part number 91353-463-005.

NLGI-2 or equivalent lithium based grease for the grease fitting on the final drive.
Brian

If you aren't having fun doing it, find something else to do.

Brian I think he needs # 36 not #35 so he is correct on the size, 60.5x2.4 but I would order it like Brian said from Honda...Should get it in a few days, I have no idea how long shipping from UK would take..The o'ring is round not flat on one side...Pat I love how you barrowed Admins. photo, how cool is that..I still haven't figured out how to do the arrow thing on photo's...duh... :lol:

Thanks for the info littlebeaver. I believe you are right. I measured the inside diameter and it is close. I'm still not sure if they use the I.D. or O.D. for sizes for O-rings, I even searched the internet to find out how they do, and still can't figure out what they mean, LOL :oops:. But I am going to my Honda Dealer today to get this ordered.

As far as the arrows. One time I was looking for a free program for removing red eye for my daughter. I ran across a totally free for home image viewer/photo editor called FastStone Image Viewer. It is a very easy to use, light program that I use to crop, draw, and other simple stuff.

Well, I went to my local Honda dealer today to order the O-ring for my final drive. They had the one that is listed in the parts diagram that is 60.5X2.4 in stock. Low and behold, it is not the one that fits. I had thought that diagram was wrong all along. Ad that diagram is the same one three other sites too. So he ordered the smaller one for me, but I still don't think it is the right size at 57mm. It will be in next Friday and we shall see. Also, the one I had that had been pinched, was flat on the inside. The replacement is just a simple O-ring, so I think it had been replaced before. If the 57mm isn't small enough, as I suspect, I will need to take it to a supplier of industrial parts and try to match it. I will post the outcome. Good thing it is not riding season.

Littlebeaver, the schematic is wrong. I have run into this a few time in my 30 plus years, and mother Honda is no different. Neither one of the O-rings listed in the pic are the size that my final drive needs. The 57 I believe will be too small. I had the final drive with me at the dealers today, and when they looked it up, the parts chart called for the 60.5mm. It was in stock, but was too big. They were scratching their heads. I assured them that this isn't the only schematic that is incorrect, and pointed out a problem we had when ordering parts a few years back. So you or Brian weren't wrong, you just weren't right, and I won't know what is the right size until I get one that fits correctly.

Bike bandit was the first place I looked. They no longer ship that part, and it was listed as the one the Honda dealer had in stock that was too big. By their measurement of my partially crushed O-ring that I had with me, as close as they could get, it was 54mm inside dia. I will post what size works for it. My bike was manufactured partly during the 83 era, and some of the wiring isn't either 82, or 83, so I thought perhaps they had a little different final drive too. But the part is the same for both years.

That makes sense-I redid the final shaft on my cousins bike about 3 years ago-perhapes I just got lucky and got the right o-ring. Regards, Johnyy

Pat you got me all curious now..Wonder what mine is? I just ordered some new tires[Spitfires,Bridgestones] so when I remove the wheel, I am going to measure mine...Thanks for the heads up..One time I took a o'ring to Ace Hardware and matched it up to their selection there for my Nomad final gear drive, it worked great for years..

Don't worry about the flat o-ring. It started out round but being squeezed into position for an extended time they tend to flatten out. That is how it seals by distorting into the shape of the fit and that is why they need to be changed. It is a normal wear item. For the price of an o-ring it is not worth trying to reuse if it shows distortion.
