Removing float pin
Permalink  
 

I am currently rebuilding a 94 OE, amongst other things I found that the float valve wasn't closing properly. I have read the warnings about breaking the posts while trying to remove the float pin, so I was hesitant to try and remove the valve at first. After a bit of reading on the internet I found a tip to use and automatic centre punch to remove the pin. Got one from Halfords http://www.halfords.com/workshop-tools/tools/hand-tools/halfords-automatic-centre-punch and it worked a treat! the pin popped out with ease and the posts remain intact.

I just thought I would share this little tip with everyone to save future heartbreak.

 

I will post some pics of the bike when project is finished.

Hi Mike and welcome to the forum!

Anything that can help prevent the dreaded post breaking is welcome but, being a bit slow on the uptake this morning, how does the tool actually work - is it spring loaded or summat?  confuse

Hi Brian,

 

Yes the tool is spring loaded, just press it against the end of the pin and it creates a "kick" during the process. Its very light but enough to move the pin. It took 3 pushes and the pin flew out.

The video I got the idea from is here:- https://www.youtube.com/watch?v=IAmEOM81R8E

I probably should have referenced this in my first post but had to go and find it again...

 

Mike

I love this website!

Night before last I got home and fuel was pouring out of the carby overflow. Tapping the carby and fiddling about did nothing so with a heavy heart I knew I had to pull the carby and tackle that float pin. When I rebuilt the carby 2 years ago I left that alone as I was nervous from all the broken post stories.

Used this tool (I bought 2 years ago just in case..) 3 clicks and out the pin flew, 3 or 4 clicks to put it back in. Sorted in about 10 seconds. I can see how it could easily be a drama getting that thing out. Cleaned all the built up crud and grime from the float needle valve and seat and all good to go again.

Happy days.

Leigh.

I recall a question about which way the pin comes out and goes back in - just follow the arrow wink
