V85TT Front Axle Wrench

[GerryAZ]

OK, I have searched the forums, the store, and even used Google as a general internet search after already looking through the service manual without success. Here is my question: Is there a special wrench or socket available to fit the head of the front axle? I have attached a photo for reference. I realize I can probably loosen the 30 mm nut while leaving the axle pinch bolts tight, but it seems to me that the nut should be tightened to appropriate torque before tightening the pinch bolts to avoid putting the forks in a slight bind.

Tools are available, see image below. I just need the ID of the axle. Below it is a how to from older manuals on the procedure for wheel R&R.



Beginning after the axle is fully inserted:
1. Install the washer and tighten the wheel nut finger tight.
NOTE For temporary alignment of the front wheel, it is not necessary to tighten the two axle clamp screws (left side) to the specified torque value.
2. Tighten the two axle clamp screws just sufficiently to prevent the axle from rotating.
3. Tighten the wheel nut to its appropriate tightening torque.
WHEEL NUT TIGHTENING TORQUE: 57.86 ft lb/80 Nm
4. Tighten the two axle clamp screws.
AXLE CLAMP SCREW TIGHTENING TORQUE: ~9 ft lb/12 Nm
5. Loosen the two axle clamp screws (left side).
6. Replace the left and right front brake caliper.
7. Apply the front brake lever, and then push down on the handlebars, compressing the fork springs several times. This will align the fork tubes.
8. Tighten any remaining axle clamp screws (as applicable).

Yes, the end is about flush with the fork leg so using a bar or round shank screwdriver (what I have done on other bikes) is not possible—hence the reason for my question. I will measure the inside diameter of the axle and reply later. I will also try to measure outside diameter since pins on tool cannot be too long (unless they are spring loaded to be adjustable). I would like to get a tool fabricated so I don’t have to tighten/loosen/tighten the clamp bolts (prefer not to wear the aluminum threads in the forks more than necessary).

Thanks for the assistance.

I finally had a chance to measure the end of the axle. ID is about 24 mm and OD is about 30 mm. The ID is slightly over 24 mm so a 24 mm wrench would fit.

Interested if anybody found where to purchase this tool?
I’d like to avoid undue wear on the small axle pinch bolts.
Thanks for any info.

I looked in the GTM Store and didn't see one listed. May be factory only. Doesn't look to hard to make w/ bar & roll pin or solid pin. Good enough for 60ftlbs.

3 years ago, GTM said he could source these if there is enough interest.

I was definitely interested, but may have been remiss in not clearly stating that. I did check the GTM Store periodically to see if they were available.

This a Ducati tool used on the front axle while the axle nut is being tightened. It fits Ducati 748, 916, 996, 998, 749, 999, ST2, ST3, ST4, 620SS, 800SS, 1000SS and other models that use a 25mm ID axle.

It might be good for somebody to confirm the true inner diameter on the Moto Guzzi as a previous poster said larger than 24mm and I suspect it is actually 25mm as well.

I will try to measure the inside diameter more carefully the next time I roll it out of the garage. Thanks for noting the Ducati tool reference.

Indeed, thanks John. These are made by K&L, of which I can get, but won't bother.

You already did, above, it looks like.

For wiw I have just measured the ID & OD of left end of front axle on my '22 model with a digital micrometer. ID = 24.71 , OD = 29.87
