If the handlebars on your Triumph seem to have excessive play or if they appear to be slightly out of line, it may be time to replace the rubber shock absorbing bushings located in the top triple tree. These bushings (97-1527) do occasionally go bad and are fairly easy to replace.
First you must locate the nuts that hold the handlebar P-Clamps to the top triple tree. Undo the nuts, but take note of what order the cups, rubbers and beveled washers were originally installed. They MUST go back on in the right sequence. It is a good idea to check your parts book and make sure that they were installed properly to begin with, (you never know what the last guy did). After you remove the nuts, cups, washers, etc., pull the handlebars straight up until the handlebars clamps are clear of the top triple tree.
The bushings should be clearing visible now. Using a socket or a bushing driver that has an outer diameter just a tiny bit small than the outer diameter of the new bushing, you have to to drive the old bushings out, then drive the new bushing in until the top of the bushing is flush with the top of the hole in the triple tree. Sometimes the inside of the bushing will drive out and the outside ring will stay seated in the top tree. when this happens and you don't notice it, you will probably assume that we sent you the wrong bushings. WE DID NOT send the wrong parts, they are all the same. They measure about 3/4" O.D. Trust me, we sent the right part, you just didn't get all of the old bushing out. If it gets to this point, (we get a call about once a month from someone thinking we sent the wrong part for this exact reason) you probably used something that was too small in diameter to drive the old bushing out, and the outside of the old bushing is still remaining in the top tree.
AGAIN, find something SLIGHTLY smaller in diameter that the new bushing and use it to
drive out the remains of the old bushing.
If worse comes to worse, you can split the old bushing shell with a cold chisel. After you drive in the new bushings, simply reinstall the handlebars, cups, rubbers, etc. in the proper order, then re-tighten the nuts.
