I had a bizarre and irritating discovery waiting for me in my garage a few weeks back. For no reason, the glass from the temperature gauge on my Ducati 748 decided to crack and shatter into several pieces. As I said, pointlessly irritating.
Undeterred, I headed for Ebay and managed to get a new gauge. I looked online for some instructions on how to fit it but they were a bit sketchy. So I’ve documented the process for removing the entire clock / instrument assembly just in case it’s helpful to anyone.
** UPDATE: EVEN the new clock has cracked now. Very strange. But at least I know how to change it!
Step 1: Make room and make sure it’s clean and dry.
You’ll be fiddling with electrics so don’t do this when it’s raining! Basically, it’s a Ducati, so you know the score.
Step 2: Get the stuff you’ll need…
One tip, I find it really handy to have an old screw / washer box handy with loads of compartments. Every time you get to a new step, you can keep the bits in the next compartment. Keeps everything neat and it jogs your memory when you follow the process backwards to reassemble.
Step 3: Get ready to catch the left fairing!
If you have a proper track stand, ignore this step but if you’re using the side stand, it’s good to put something soft on the floor on the left hand side of the bike. The centre stand goes through the fairing so it’s just easier to let it rest on the floor… but without getting scratched.
Step 4: Undo the fairing fasteners
Undo the 4 obvious fairing fasteners on each side and the two under the bellypan. The ones underneath are usually a bit stiff from all the road muck, so sometimes helps to use a screwdriver to gently flip the faster. It’s good to give them a bit of a going over with a wire brush or similar and lubing them up for when you put them back too. Remember the fuel overflow tube too, you’ll need to poke this back through the special hole when you put the fairing back.
Step 5: Remove the fairings
With all the fasteners off, it’s fairly obvious what happens next, just be ready to catch the fairing panels! Remember that the section below the air intakes has a little lip on the inside (circled) so don’t try to pull them at right angles… these panels are expensive!
Step 6: Remove the mirrors
You’ll need to remove the nose fairing and you can’t do that without removing the mirrors first. Undo the small bolt on each mirror and gently work the mirrors free of the clips that are gripping the two pegs. Be careful with this step as the bolts are especially made to shear off so don’t use too much force.
Step 7: Remove the nose fairing
Remove the allen bolt from in front of each air intake to release the nose fairing. Gently pull it forwards and put it somewhere safe. It generally falls over if you put it on a flat surface so either prop it up with something or store it ‘nose up’.
Step 8: Remove the lights
Remove the small headlight adjuster screw located in the middle of the the two headlights. Two things to note… there’s a spring on it so get ready to catch it when it falls and the number of turns affects the headlight beam direction, so take a note of it. When I removed mine, it took 15 full turns to release the bolt, so I did the same when tightening it up later. When the bolt is out, push the entire headlight assembly from the back to release it from the two rectangular rubber grommets above each headlight. May take a few wiggles… and again, get ready to catch it.
When you’re clear, allow the whole unit to gently dangle without removing any of the connectors.
Step 9: Remove the horn
There’s an important bolt behind the horn, so remove the horn. The horn bolt is tucked right underneath the nose. Take note of how the horn and connections sit in the cutout in the headlight housing. It’ll just make it easier to refit it later.
Step 10: Locate the 3 magic bolts
The instrument panel it attached by 3 bolts and they’re hidden pretty well, especially the farthest one (bottom circle in the image). You’ll need a socket set with small extension bar for these bolts. The farthest one is a real 45 degree number, right underneath so take time to locate it.
Step 11: Remove the clocks
I’m just interested in the temperature gauge but it’s the same process for the others, more or less. Remove the single bolt holding the gauge being careful not to lose the small bevelled washer, then draw the whole clock, wires and all through the face plate. The reason I say to leave the wires attached is that on reassembly, it’s easier to reattach the wires with the back of the clock easily accessible than it is to try an attach the wires through the back of the face plate assembly too.
Step 12: Remove the wires
The wires should be pretty much set in their positions but do make a not of which one goes where! They just pull off the spade connectors. The small bulb to illuminate the dials is fed into the dial through the rubber grommet. Gently but firmly pull at the grommet to release it (as shown in the second image).
Step 13: You’re done!
Here’s a pict of the ‘tray of bits’ too, to show you all the fasteners and whatnot in the order they came out.
Step 14: Reassembly
Simply do everything in reverse to put it all back together again remembering these points along the way:
1) Put the connector on the clocks before you bolt the clock back into it’s housing.
2) Don’t over-tighten the three main ‘magic’ bolts. The instrument panel can crack.
3) Make sure the headlight ‘rectangle’ grommets are properly pushed onto the flat pins.
4) Screw the bolt between the headlights the same number of turns as you did to remove it… and don’t forget to to put the spring in there first.
5) When fitting the fairing, remember the tabs on the side panels, to make sure the petrol overflow tube is poking through the hole and lube the bottom two fasteners well.
Very helpful made my life alot easier.
Thanks for taking the time.
safe riding
Excellent guide. Having just had the temperature gauge ‘glass’ shatter on my 996 in the same way as Dino, this was a an ideal guide for me. I’d add three points to make it even better though: 1. once the instrument panel has been freed, remove the speedo cable at the instrument end to allow better access to the rear of the instruments. 2. When refitting the headlamps, insert the adjusting screw and spring before inserting headlamps in the housing, otherwise you’ll have to take the unit out again. 3.When refitting the nose fairing around the headlights, fit the two lower screws and the mirror screws loosely to allow all the holes to line up before tightening.
I bought a nice carbon cover for the gauge assy of my 996S and was suddenly aware that it is not an easy job to remove the whole thing.
But you’re guide made this challenge a lot easier. Thank you so much for taking the time! Your photo’s are also very useful.
Brgds,

Excellent guide mate, saved my hours of grief 🙂 Thanks really appreciated your effort in writing the guide.
No problem at all. Strangely, another of my clocks has decided to crack so I’ll be using the guide myself! 🙂 Really not sure why it happens though.
Thank you for posting these instructions. I had to remove all the gages to put a carbon fiber panel guard on, and it sure made the job easy! Great guide!
thanks!!
…if the Haynes manual went through it like this it would be nice…it might be a foot thicker but at least it would be concise…
hi there,thanx for taking the time,ihave just replaced headlight bucket,bike knocked while parked,i still would be searching how to do it if not for your guide,thanx again,stay safe.
Excellent little article and I don’t even have a bike. Still the best looking bike out there but should be OK parked in the living room next to me when I get around to buying one.
Cheers Marco! I know what you mean, I often go into the garage just to stare at it… from several angles. 🙂
Hi Dino,
Thanks for the very user-friendly set of instructions.
Noticed your last updated point in red:
** UPDATE: EVEN the new clock has cracked now. Very strange. But at least I know how to change it!
If this is still the case, take a look at the brake and clutch reservoir tanks (as well as the lines) and check for leaks. I noticed one day after a long ride, there were a couple of dabs/smears (only small) of brake fluids on the clock face. Wiped them off, and a few days later, cracks on the glass grew like wild fire on those exact location.
Cheers,
Q
Brake fluid… hmmm… may be onto something there. Will have a look and see if there’s any tell-tale marks on it.
Great guide for clock removal, I had a brake fluid leak, only realised when my right glove kept getting wet ! A couple of weeks later all my clocks have cracked, may be coincidence but I have owned the bike for 15 years and they were ok until the brake fluid incident.
Hi Dino, any chance you still have the photos?
Thanks,
Damian.
Yep, sorry, my old host deleted everything. Just updated the post! Good luck!
Thanks Dino, much appreciated.
I realise this is an old thread, but I’ve just bought a 916, and the temperature gauge glass is cracked. I’d like to try replacing it with perspex – have you tried to dismantle the gauge?
Yes… and it’s not good news. I’ve had 2 crack over the last 10 years or so. The plastic bezel around the rim is glued on with the glueiest glue you can imagine. I looked into getting it professionally sorted and the quote was as follows:
“All I undertake on sealed clocks like yours is complete overhauls, which costs £180 for speedos or revcounters, and £110 for the smaller units such as temperature gauge.”
So I just sat on eBay for months watching for suitable gauges. I have one sat in a box, nice and warm in the house, ready to fit when I sell the bike. Predictably, it’s not cracked sat inside, which helps confirm it’s the crappy cold weather that does it. If it helps give you a reference point, I bought mine in 2016 for £63, hence why a recondition for £110 was a daft option.
Interestingly, if you’re not that fussed about originality, the Cagiva Mito 125 has a very similar temp gauge. Lots on Ebay.
Thanks a lot for this guide. Very helpful for adding the carbon cover I bought for my 996 Duc. Nice pics and a good explanation.
