Does anyone have the spec's on the steering head bearing adjustment spanner. Size in MM, thickness and distance to the square drive for the torque wrench. Don't want to spend $$ on Triumphs wrench, can get one cut on a water-jet at work.

The Haynes Manual for the New Bonneville says "Note: Two thin 38mm spanners are required (Triumph Part No. 3880140-T0301) which have an offset square cut into them to accept a torque wrench." So I guess 38MM & thin will work times 2. The picture just shows the distance to the square drive to be enough to clear the head of the torque wrench. That way it will be as close to bearing centerline as possible for the proper torque reading. Maybe 1 1/2 or 2 inches. The nuts look to be 1/4 inch thick or less. It also says the adjuster nut preload torque is 40NM & then the lock nut torque is also 40 NM. This information & $1.50 will get you a cup of coffee. Bob.

I bought a pair of Triumph steering head race adjusters for $25.00 each; an outrageous price for what they are. They are 38mm, the 3/8" square hole for the torque wrench is approx. 1 1/2" from the center of the adjuster nut and are cut from 5mm (approx. 3/16") mild steel plate. If you can cut your own on a water jet machine, more power to you. Hell, cut several and sell them at $25.00 for the pair, there might be some takers just on this site, not to mention E-Bay.: I'd like to see more reasonably priced aftermarket tools for Triumphs.----James.

Thanks for the info guys. I would love to do a production run of these after the proto is made. Unfortunately the people I work for will help me out but won't tie up equipment or labor for my profit. I would like to have a small machine shop when I retire and make custom accessories for our Triumphs.

Can anyone post a pic/specs or trace a drawing of this so I could get one cut

James, can you get more at that price? The local dealer here wants $55.00 each or $110.00 for a pair. I'd gladly buy a pair for $50 if you can get them.

Is there no way around using these spanners?

This is a helpful thread because I've been thinking of lubricating the steering head bearing. I actually didn't know that specialty tools are required and $25 or $55 or whatever the going rate is seems like a lot for a once-every-three-years tool.

Can ask a question though: What is the realistic useful life of the steering head bearning if its not maintained? Put another way - what's the real risk I'm running by just letting sleeping dogs lie? I know its not an ideal approach but the front end still swings freely when I have it up on the lift.

Thanks,

P

I said "screw the special tool" and went to Sears to buy a 38mm wrench. Problem is, the thing is as long as my arm and cost an arm and a leg!



So then I went to Harbor Freight thinking I could pick one up cheap, wrong...I had to buy a whole giant wrench set that goes up to 50mm if I remember correctly! It was still cheaper than the Sears wrench was. The huge wrenches look hilarious in the garage, like something hot rod calender girls would pose with.
