1998 EV removing/replacing front wheel and tire?

[maquette]

Can someone direct me to a source to find the correct torque specs for the bolts that hold the brake calipers to the forks, the torque for the ring nut that hold the spindle, and the four pinch bolts for the spindle?

Also, on page 33 of my owner's manual, under tyre fitting it states that for a tyre with an arrow, the arrow should be pointing AGAINST the direction of rotation on the front tyre? Is that correct? It goes on to say that those instructions should be followed unless otherwise directed by the tyre manufacturer. Where would one find that information?

I've done searches for the torque specs and get varying results and I always thought the arrow on the tire indicated that it should be mounted with the arrow in the direction of rotation?

Thank you.

If you're using a modern front tire on the front of the bike, mount with arrow facing the direction of rotation.

It's bout the same as the SP
Brake- 32ftlbs
Axle- at least 60ftlbs
Pinch on bottom of forks- 7flbs

The direction arrow reversed comes from running a new tire on the front and taking the tire that was on the front and putting it on the rear. I think this comes from this being the practice in past history to get more milage for the frugal rider. Be damn careful with the pinch bolts or you will break off the little bit of fork below the axel.

OUCH!  Careful!  IIRC, the early Tonti bikes used a single pinch bolt at the bottom of the fork.  That pinch has a 17mm external hex head and I think 10mm diameter shank.

However, the 98EV fork uses TWO, TINY pinch bolts at the bottom of each fork. They have a 4mm or 5mm internal Allen hex.  Those head sockets round out VERY easily.  The shank is perhaps 4mm?  Using the same torque as specified on the early Tonti is a recipe for stripped bolts or snapped fork lowers.

Also, tighten the axle nut before you tighten the fork leg clamping bolts.

What Patrick says. It doesn't take much to keep the axle from turning. Blindly following torque tables in a Guzzi manual can get you into trouble. They may or may not have been updated from when it was originally written. I ran into one that called for 18 foot lbs on an M5 bolt.

Pinch bolts are 6X1 GO AHEAD DO IT FOR A LIVING, EVERYONE ALWAYS TRYING TO PROVE ME WRONG

Thanks for all the replies. I decided to use the numbers Steve posted and put the arrow in the direction of travel.

Make sure that tire on the front is specified as a front tire. This summer I put a set of Shinko's on a mid dual sport. The front tire had two arrows on it, one for front and the other opposite if mounted on back. 
If I would of had to guess I'd probably done it wrong.

Avon Road Riders carried two arrows and could be mounted front or rear. Direction of rotation depended on placement.

I don't agree with the recommended axle nut torque specs. Certainly aren't going to hit 60 ft/lbs with the kit provided wrench. Certainly aren't going to be able to pull the axle at 60 ft/lbs if necessary while on the road with the kit wrench. The outside of that nut isn't designed to be rotated to 60 ft/lbs. That's almost as bad as the 100+ ft/lb spec for the rear axle on my T-3.

You want the axle nut tight enough to clamp the bearing and spacer stack firmly against the nutted side fork leg. That's all it has to do, just keep the bearing stack in position and alignment. All the loads on the axle are radial!

Torque the nut to 20-25 ft/lbs and you have all the clamping force you need to hold everything in position and alignment.

I'll be sending Tom a hex nut to replace the stupid ring nut Guzzi used. Anyone else need one? I still have a few more.

I always figured that the unique ring nut on my EV was to keep people from stealing my front wheel!
