Going Pear Shaped!

Post by MarkN » Tue Feb 09, 2016 11:45 pm

I posted a couple of days ago about the butterfly flap sticking in my exhaust. After a few goods replies and some reading and research, I decided to replace the valve with a piece of pipe bought from Nippy Normans for £29.

£29 was a lot better than paying the £350 +fitting that I had been quoted for a new one - or so I thought!!

I ordered the part on Sunday evening and thought I'd start to take the exhaust to bits today (Tuesday). After loosening the end can I started work on the clamps on either side of the valve. This proved a bit tricky so admitted defeat, got in the car and went to Halfords to buy a set of Star Point drivers (£22) rather than mess around with the "allen"key type I had. Got home put the T45 on the end on my ratchet wrench and proceeded to snap the bolt head off, this also happened to the second one.

How do I get them off now? decided to get my Dremel out and cut the bolt, only problem, no grinding discs left, get in the car and drive to B&Q to buy some more £5

Get home and manage to get the clamps off. Glean up the exhaust and get everything ready for the rebuild. I then order two new clamps (£20 inc P&P)

So far this little bit of pipe has cost me £76 plus my time and a drop of diesel!

But it is building character?

Been a few times when I've been down farmer Freds and hes got the oxy acetalene out on my bike to loosen up some sized stuff and I thought...... This was going to be a happy hour of fettling in the garage. That was 6 days ago.....

Did you soak the offending bolts with wd40/pen oil etc a couple of times for a few days as advised prior to trying to remove ?

the bolt heads shearing off is rather common on this job unfortunately fella

Beginning to think that some manufactures are using 20 p cast bolts.
You know the type, they look good but are manufactured by some high speed injection process and are so hard you cannot cut them with a hacksaw, very brittle.

I sprayed load of oil on the bolts, all to no avail. They had been on there for three years and were very corroded. A bit of a pain but it did mean the bike got some shiny new bits added. (thumbs)

If you haven't done so already, get some nickelslip or coppaslip on the threads now before they get a chance to corrode.

May not make much difference, but I would have fitted them with the bolts at the top, less muck splashing about them and easier to add a drop oil now and then.

More importantly, the writing would be the correct way up (thumbs)
