Was out on a trail last week and both(!) rear mudshields just plain fell off (recovered them on the trail coming back — nothing like leaving a breadcrumb trail of parts). I knew they were getting ratty, but still...

Just ordering new ones; does anyone know what size bolts they are attached with? Might as well get them at the same time...

Thanks!

 

It's part number FS106127L (M6 X12MM). I don't know the thread pitch, but you can get them here > FLANGE SCREW M6 x 12mm, RND768, FS106127L - Rovers North - Classic Land Rover Parts
And don't forget to order a decal for your bumper.

 

Ah, perfect! Thank you!

 

And because nothing is easy: 5 of the six bolts sheared off in removal (in spite of a sea of PB). They're weird bolts with a spiral cut along the tread — some kind of self tapping? Makes them weak I think.
So now it's wheels off, brakes off, drill out the old bolts... good fun. Why wouldn't changing 6 bolts take all afternoon?

...later...

and i I can't get any drill in close enough even with the brakes off because the hub is in the way.
Tried every rotary tool I own and am running out of ideas.
Off to Canadian tire for bolt extractors but I don't have high hopes.

 

Do you have a right angled extension to fit your drill?

Be aware that if the bolts are 'self tapping' they are likely to be hardened and will kill any normal drill bit.

If possible start with a centre drill bit of the appropriate size first and then use a titanium drill bit.


................. "They're weird bolts with a spiral cut along the tread" these spirals are used to enable rust release in many cases by working the bolts back and forth and aren't hardened bolts.

 

Yeah pretty much my conclusion too.
Just bought the 90° drill attachment. Was the only useful looking thing at Canadian tire.
I should have done more back and forth, and stopped when the first one snapped, but that's hindsight. I have excellent hindsight...

I am worried about the hardness of the bolts vs the softness of the casting. Probably going to make horrible holes.
I'm assuming that if all else fails I'll be able to just run a nut and bolt through the lot. Looks like there's space to me.

 

Is that the only function to those spiral cut outs? I see those used on a lot of interior bolts. I always wondered what the function was. Seems wierd that they are used on the interiors.

 

Hi Abran, to my knowledge it's for releasing from rust and corrosion whether interior or exterior. IMO it allows a release oil/fluid to percolate along the length of the bolt or screw, well that's my theory, I'm probably wrong though .

 

"I have excellent hindsight..." don't we all Fallstaff, we are the worlds most stupid 'engineers' in most cases ............ we live and learn,........... but only sometimes eh


One broke/sheared on me last year ............ so I quit whilst still ahead as I was gonna paint the mudshields but, hey ho, they stayed rusty.

TIP: when you put your rotors back use C/S stainless screws, I think they're M8x1.5, with Allen heads but fill the Allen heads with grease.

 

makes sense to me.
