Author Message   Slingshot Posted on Sunday, February 26, 2012 - 08:34 pm:        Hi again I just got finished installing a new set of rear isolators. Outside of the obvious difference from the original ones the new ones did not fit into the frame as well as the original ones. Has anyone had this same observation as me or did I get bad iso's. 2000 x1 after setting into the frame where they are held on by the bolt there seems to be a 1/16 of an inch shorter lip then the originals. Don't want to ride it until I hear that these are good! Thanks   Buellistic Posted on Sunday, February 26, 2012 - 10:13 pm:        How about PART NUMBERS ??? PICTURES would help ???   Oldog Posted on Sunday, February 26, 2012 - 11:04 pm:        Slingshot did you get them from a dealer? they have a specific orientation that they fit in and there is a left right IIRC there are only two versions that I am aware of check the left right do you have a FSM   Slingshot Posted on Sunday, February 26, 2012 - 11:15 pm:        got them from the dealer and yes there is a right and left that is not the problem. the new metal lip is towards the front of the bike. What I am not sure of is that the center part where the big bolt is does not go as deep as the original ones did.   Slingshot Posted on Sunday, February 26, 2012 - 11:35 pm:        Here is a pic the arrow is where there is a space that the iso was too short to fill up the space. The original one was tight to the edge. Are the new ones shorter then the originals?

I'm certainly not an authority on this but I'm not sure that the tolerance of the frame guide lip and the frame hole matters so much. The roll pin sets the iso in the correct place and the iso bolt is very precise as to how it has to go. The rest is compressed between the frame and the swingarm. I think what matters is that the strength of the bond between the washer and the rubber stays solid, that the rubber doesn't deteriorate and start separating and splitting, and that the bolt is torqued properly.   Jim2 Posted on Monday, February 27, 2012 - 12:59 am:        I don't see the washer behind your bolt. The picture just might now show it. You do have the washer, right?   Slingshot Posted on Monday, February 27, 2012 - 01:19 am:        If you look at the lip of the old one and the new one is shorter then the old one. Yes the washer is behind the head of the bolt. I did the install correctly. I would think that they would at least manufacture the lip to be the same as the old one? Not shorter. That is the question that I am wondering about   Slingshot Posted on Monday, February 27, 2012 - 01:24 am:        My concern is that that little lip is the only thing that hold the frame to the engine and back wheel. With the new one having less contact area that worries me. Not being an engineer. Is this normal for the new iso to be shorter in this area then the old one?   Oldog Posted on Monday, February 27, 2012 - 01:55 am:        Side plate secure? pins in the indents? Mine are a bit off of the lip ( not all the way in )   Slingshot Posted on Monday, February 27, 2012 - 02:06 am:        Oldog yours are a bit off too. Have you had any problems with it that way? Maybe that is the way they were engineered?   Slingshot Posted on Monday, February 27, 2012 - 02:07 am:        Yes side plat secured and pins in place where they should be my concern is the bit off you are talking about.   Oldog Posted on Monday, February 27, 2012 - 02:10 am:        No Not any that I have noticed, you should be ok, I did notice the gap that you describe, You are working on an X1 ?   Oldog Posted on Monday, February 27, 2012 - 02:14 am:        one thing to watch for is as you torque the bolts (the big socket heads ) that the rubber parts dont twist from the bolts torque, the fsm has you draw a pencil line across them its easy to see them twist what I can see looks ok....   Slingshot Posted on Monday, February 27, 2012 - 02:23 am:        I did that and everything is okay. I put anti seize under the head of the bolt. When did you do your iso's and how long have you been riding it with the space in the lip?   Oldog Posted on Thursday, March 01, 2012 - 11:07 am:        sorry Quite a while your ok...   Rex Posted on Thursday, March 01, 2012 - 12:53 pm:        I wonder how long the Rubber on the isolators are recommended on lasting? A certain time limit, where the rubber begins to come apart? just wondering. Hd or Buell still stock the isolators?   Two_seasons Posted on Thursday, March 01, 2012 - 04:28 pm:        American Sport Bike has them   Jramsey Posted on Thursday, March 01, 2012 - 05:41 pm:        "Hd or Buell still stock the isolators?" They will be around for a long time as they are the used in the big twins,Al's are priced less than HD dealers.   Purpony Posted on Thursday, March 01, 2012 - 11:08 pm:        i dont have an isolator that i can hold in my hand at the moment... but wondering if the way they are made, could they be machined down to be a little thinner? (Message edited by purpony on March 01, 2012)   Purpony Posted on Friday, March 02, 2012 - 12:20 am:        to answer you original question, mine has the same gap you are referring to with the new isolators installed
