I need to remove the fuel cap holder from a 600 ss tank in order to clean out and service the bits in there. I've removed the cap itself, and hear the holder is removed by removing grub screws. I see something like grub screws, but what may in fact be rivets to drill out. Not sure. Doesn't appear to take an allen key or to be slotted. Here's a photo with close up. PLease advise!
There are grub screws alright, about 8 of them distributed around the perimeter of the filler assembly. They use a very small Allen key, about 1.7mm or 2mm. It's probably best to soak then thoroughly with a penetrating fluid for a day or two before trying to undo them.
Also, even when the grub screws are undone, the filler may still be a tight fit. I struggled with mine for ages. In the end I put a stick (hammer handle) into the hole in the filler hole and gave it a wiggle. Then it was straightforward. And when you're putting it back together, be careful how the rubber gasket fits. It's easy to get it wrong, and if it's not right, you won't get it back together... Cheers, Nick
Thanks guys for the confirmation… appreciated. (I couldn't see the hex socket in the screw heads even with a jewellers loop! I hope they are not worn smooth….). Now I can get down to it with confidence.
also, while you are at it - think about 'externalising' the fuel filter. If you just want to get on and finish the job you started then maybe not this time but most of us do it as it means you can both check it and replace it with ease compared to when it's inside the tank.
they are good quality grubscrews with a deep hex as std so it's worth (after soaking with release agent) getting a good quality/snug fitting key in as deep as possible before you apply leverage as when it comes to undoing all of them succesfully, usually 'there is always one' !!
I shall - it makes sense to me. Just need to get a good look at the parts inside before I order up. ANy ideas on a good cheap filter for this year??
I have four grub screws out ,using 2mmm hex. Unfortunately, four are well rounded, due to previous owner's attempts here. ANy tips on their removal would be appreciated; I can only think of trying a left-hand thread pilot drill bit… if I can get hold of one.
If you can find one small enough tap in a torx screw bit they work really well on rounded Allen heads.
any decent inline is fine - same size as original-ish. Halfords still sell one but expensive. 10 x Universal Car Parts LARGE Inline Fuel Filter Auto Petrol 6mm 8mm Pipe | eBay
You know, exactly that was in my mind… somewhere in the back of it. I haven't the right size at hand - must have got rounded from similar use in the past …. I'll get another and give it that a go. SOunds ideal. Thanks. Update: it worked a treat! All out.
I've got the innards out of the tank. There's a lot of dirt in the tank, as well as the carbs. I guess a lot of this is due to a flush filler cap. The fuel filter is filthy brown … which means the pump must have been dealing with a lot of muck too. Apart from rinsing and testing the fuel pump out of the tank, is there any special way to clean it I wonder?
not really bar taking it apart, the new neat petrol ought to be enough but if you think the'teabag' filter on end of pump is partially blocked then might be worth investigating. Generally if motor pitch is consistent and high enough/picks up quickly then it'll be ok. New pumps are around £35 last I looked but not from Ducati.
