Steering Bearing Replacement

[sonny]

I used Lucas green. High grade marine grease. Heat is really not a factor here but moisture is.

I changed my tires recently, front michelin and rear exedra combination....the wobbling started after that....before it was stock Metzlers, front was cupped but still never felt such strong 100mph wobbling....but I guess 6500 no adjustments means it is needed some how....let’s see what $ dealer asks for.....I will learn to do it myself if it’s killing high

Have you started it? May be I am looking at the wrong place?

Resurrecting this old thread for some additional advice. I have the R3T and bought the All Balls kit 22-1053. The bearing cups are pressed in and the lower bearing is on the sterrer with the dust seal in place. Problem I have though is there aren’t enought threads for the second setting nut when I put the first nut back on the top. I tried putting the top bearing in with and without the dust seal, but still not setting right. Wondering if others have had issues with the All Balls stack height after replacing the headstock bearings.

Good call. Here are pictures of the bearings installed. Everything looks installed properly, but I don’t have enough threads for the second nut. When I look at the grease marks on the upper polished section of the steering stem, it appears the upper bearing has another ~1/4” to go. I don’t have any binding, so I believe the cups are seated properly as well.

Here are some pictures of the cups installed in the head tube as well. These are the new ones. Several angles of the bottom and top to see how well they are seated. Either the bearings are wrong size, or I am doing something incorrectly:

Looking at those pics, it would appear the cups are properly seated but to check, you can try and place a feeler gauge between the cup and seat surface... should be a no-go. Also when looking at the steering stem bearing install, it's hard to tell if you have the spacer in the right place. From Hermys Triumph Estore it shows the stem (22), then lower brg (24) (surprised they don't show the seal), then upper brg (26), then brg cover (27), lower adjuster nut (28), alignment washer (49), then upper adjustment nut (29). The tapered roller brg sizes are listed also.

Bottom brg size is...

Top brg size is...

Hope this helps...

Thanks for the tips. When I took off the adjuster nuts, I didn’t have an alignment washer and there certainly isn’t room right now for another washer on the stack. But will look at the seating again. I may just order the OEM bearings because they had integrated dust seals, which may reduce the stack height somewhat, but not nearly as much as needed. As it is, I found the bearings to be the same height as the OEM, but I didn’t measure the bearings with cups before installing. Lesson learned because I’ve not had problem with installing the headsets on bicycles.
