Removing fuel cap

Hi, 

I was wondering if I could ask anyone for a bit of advice in how to remove the fuel cap from the tank. 

All of a sudden I can no longer get my key to fit fully into the lock and consequently I am unable to open and fill up the tank. I think it is corrosion related. I have tried penetrating oils etc but have had no joy. 

I have pretty much resigned myself to having to fit a new cap but am not entirely sure how or if it would be possible to get it off. 

It is one of the push locks on a Honda CB500 V (see pic). The outer ring surrounding the actual cap has allen bolts that I can remove. The ring then rotates with the central cap just less than 180 degrees and does lift up a little but has a flange underneath that prevents its removal. The cap won't come out of the tank as I presume it still has an internal locking device within the tank itself. Essentially is the lock going to need drilled? I was hoping to be able to do it myself rather than have to pay a garage to remove it but am starting to think this might not be feasible. 

Many thanks
Rob

Stuck fuel cap.

I had a similar problem on one of my bikes. I thought the key wasn't going in far enough too. In fact it was, but the latch had jammed. There was another bolt under the flap securing the cap to the tank so I had to resort to sacrificing a spare key. I put the key in and gripped it with pliers as low as possible, then used brute force to turn it. The key bent a bit but it freed the latch and I've had no further problem. It was a bit desperate though! I've since come across this article which suggests drilling a hole through the cap to reach that last, hidden bolt.

This stuff is brilliant for seized locks, it's powdered graphite. I used it just about a month ago on my SV for the very same problem you're having. Just squeeze some into the lock and work the key in and out and gradually try turning it a little at a time. If it won't turn then put a bit more in and keep on working it in and out and wiggling the key. It can take about 5 or 10 minutes to get there but it should work.

This stuff is the best thing for the job, if it doesn't work then I'd say it's beyond help. Try ebay or if you have a locksmith near you they'll probably stock it.

latch

Sounds like the latch is jammed as James600zx, I would spray RAPIDE DP-60 all around, re-fit  the allen bolts and spray/flood inside the keyhole then leave for a while, after which try again with the key whilst PRESSING down the cap .

stuck lock

Thanks for the replies guys. 


That is exactly what it is like James with the key feeling like it won't go in fully. I don't want to force it though as I only have the one key. 

Will try the Rapide spray and graphite when I next get the chance which hopefully is soon as I am getting sick of using the push bike!

Will let you know how I get on. 

Thanks again. 
Rob

One key

Get another key cut :sunglasses:

That way, if you damage it trying to get into the fuel cap, you won't have to replace the ignition barrel.

Get Two cut, least you'll still have a spare if you knacker the other one.
Check it works in't ignition before you try it on't tank, just in case!

Then Again

Maybe you should get another cut , then you've got a spare for your spare
Ooh, if you get another.....
Sorry couldn't resist mocking myself, thought I'd get in there first! :wink:

On a more serious note, when you are trying to free the lock off put a little downward pressure onto the fuel cap, it may help reduce the resistance of the latch against it's housing
Best of luck getting it sorted :smile

I put tons of lube down the keyhole too but...

... if it's the latch which has stuck rather than the key barrel then any lube you chuck down is unlikely to reach the end of the latch. The excess will just drain away.

:upset:

Use the (brute) force, young Jedi (-but don't blame me when... etc).

:winkie:

Me too

Had similar probs on a fairly new bike less than one year old ZZR 1400. I think I was overfilling it then the fuel was splashing onto the locking mechanism and basically degreased it over a few months of use.

Managed to get the lock open after much hard work - at a petrol station whilst on fumes (thank the lord). Used a set of pliers to straighten the key up afterwards

Then a good old spray up with 3 in 1 oil and didn't overfill after that.
