3C Front Mudguard Rubbers

Hi Guys
I bought eight rubbers with spacers from wolfgang to install on my front mudguard bracket but the eight holes on the fender bracket are to small for the spacers.
My question is do I have to drill out the holes to install them.
 
SF, you may have actually have a very early mudguard bracket with 8.5mm clearance holes. My first 3c was like this. When they all cracked the fix was to go to the newer grommeted design. My '78 Jota has much bigger holes for grommets and spacers, sorry I can't tell you the diameter without taking the mudguard off. Maybe somebody has a spare floating around that they could measure?

Incidentally, I don't have grommets and spacers on my current Jota. Although the holes are oversized the mudguard support bracket fits very nicely between the sliders and I'm not really very interested in bending the bracket so I can fit the grommets. It'll crack, I'll fix it when it does.

I made the spacers myself,I installed the rubber grommet into the guard stay and with some dish washing liquid as lube used a G cramp to push the spacers then into the grommets.Its not as much fun as it sounds.They need to be pretty snug or the guard will wobble around like crazy,but not that tight so the vibs crack them.Use locktite on the bolts.You cannot pull them up to tight as the grommets will bulge out.
Make sure you put the guard on facing the right way,or you will be informed by mass emails.The last thing you need is to do it twice,as I said not much fun.

Why not make longer spacers and tighten the bolts up right.

My Jota's front mudguard was bolted up solid when I got it - ie. no grommets or spacers. When the (loop style) bracket broke, I welded it up and painted it black. Paint is cheaper than chrome and I thought I might be welding it again soon if prone to cracking. Seeing that the holes in the bracket were much bigger than the bolts, I figured it was meant to be installed with grommets, so I got some suitable grommets from an electrical shop, cut spacers from a bit of stainless tube and bolted it back on. It's been like that for a few years now and hasn't cracked again. I bet it'll break if I get it re-chromed though.

Cheers,
Cam

Cam, any idea how thick the outer "washer" parts of the grommets you used were? And did you have to bend the tubular mudguard bracket to get it back between the forks with the grommets in place? I've still never seen a Laverda front mudguard with grommets actually installed, just wondering what they're supposed to look like.

G'day Ken

I don't remember the actual dimensions, but I'll have a look when I get home from work and post some photos and/or measurements.

As far as I recall, the grommets didn't add enough thickness to the assembly to make it necessary to bend the bracket. It just made it a slightly tighter fit between the forks. There's enough flex in that long loop to accommodate a few mm.

Cheers,
Cam

When I first did it years ago I didn't use spacers,it bugged me for years so eventually I got around to it.If I remember right Cam offered to cut me some spacers but I already had some done.What it needs is spacers that will squeeze the grommets JUST SO.If I wanted perfection you could come up with the perfect dimension from the spacers that compressed them just enough to stop cracking and not be to long.Mine are 80% and thats fine for me.As I say to people I do building work for,PERFECTION IS HARD TO ACHIEVE ANS SYMMETRY COSTS EXTRA.I usually get the blank look  I am after.
