changing centre silencer, SWB Maverick

Don't get into the habit of using impact wrenches on exhausts in general, as if you used one near a catalyst, you could rattle it to pieces, rendering it scrap.
No problem on the td though:thumbs

As Geoffdown suggests a nut splitter is good, but some exhausts have recessed flanges so getting one in could be impossible.

When I fitted a recessed flange exhaust, I placed a spacer ( bigger nut) over the thread before putting the correct nut on, then you can see the nut and grind it off next time around, but this needs forward planning:doh.

Also consider stainless nuts and bolts ready for next time, and use copper slip on the threads.

Hope this helps..
Best regards,

Rustic

Stainless bolts arent good idea they can bind up and be much harder to remove could use ss bolts and bzp nuts.I find good quality bolts dont corrode like thet did in the old days.

Well, managed to get the old exhaust off, but I had to remove the back box to do it. To do that, I had to jack up the rear, remove the wheel, jiggery with the back box and remove. There is no way, NO WAY I would have got those bolts undone in situe. Only problem then was, I helped my mate do his BMW 1 series red brake discs and pads, so lost all the day light.

Will finish the job tomorrow, and at least that will be easy.

All i have to do then is patch up the wings, and refit for now until I get the cross member welded...

Even with the impact wrench?

Wow, you have made me feel far less of a wuss now and saved me a bomb on an Impact wrench, as I at least managed it in situ, with standard Halford sockets and spanner set... Eventually... :lol

nope, didnt even bother with the impact wrench because as expected, I needed access to the top bolt head and the nut. The problem was, the backbox end that attaches to the middle exhaust had a lip all round, so in situe I couldnt get the wrenches in at all both sides to undo with them being so tight.

so, removal of the back box was the only solution, and im glad i did as it was so much easier than doing it from underneath.

get a body lift you get loads more room then :lol

maybe when i have the welding done, im tempted to a small lift....2" maybe..although Heidi wont actually be able to get into the car if its 2" taller....

I Love My Dremel

I invested in a Dremel last year and it has save me loads of pain and grief on the bolt front. Bought some 2cm cutting disks with it and now if a bolt is seized I can use the Dremel to split it no problem.

Uses so far:

1. Split bolts to allow side steps to be removed on X Trail.
2. Reprofiled ratchet in gears on road bike after a tiny bit sheared off. New set would have been £120.
3. Cut copper waterpipe inside wall cavity that had sprung a high pressure leak. Allowed a join to be fixed.
4. Chopped through rear section of exhaust on Mondeo estate. The whole middle and rear sections were one piece an bolted on before suspension. Saved £190 on what the garage were quoting.

Its next job will be to clean up a bit of rust on the rear of Terrano.

Best piece of kit so far

cool, I have a dremel, but havent used it yet on the car. I am short of decent cutting discs, i only have what came with it. I will pick some up tomorrow because i think it might come in handy for trimming the hole in my wing before i repair it :thumbs

interesting to read it cuts bolts, think ill try that tomorrow...

I had one of the nice mains powered Dremels bought for my by my wife. It had positive feed back, so it regulates the power to try and keep the speed constant... I later found out that they have an issue with the motor windings and if you use then for a prolonged period, they burn out the motor. I killed mine cutting a U bolt off of the Volvo 240 exhaust.

So moral is... if you do use it, make sure you bear in mind it's duty cycle and give it plenty of rest time.

right ok, id better check that as im not sure. mine is a mains powered Dremel, and i know it has the replaceable bushes or springs or something but ill check the duty cycle, as i think any sort of car work i do, would be a prolonged job...

Mine was the Dremel 400, and I was quite disappointed I killed it so easily, as I had to keep stopping to change the cutting disk anyway which are very easy to break when at arms reach under a car, which made me think it got plenty of rest stops.

It suddenly started running very slow and loads of sparks were coming from the brushes, so I thought I had burned out the brushes, and ordered replacements. Fitted them, but it was the same. Turns out the motor windings burn out, and from searching on the web, it is a pretty common problem on that model. I took it apart and you could see where the resin was black on the armature.

I just buy the cheap ones from Costco now, and can afford to go through 3 or 4 before I have paid the equivalent. The only things I miss are the "Electronic feedback control" and "Soft start function", but luckily all the attachments still fit the Costco one.

well, i fitted the centre box today and im pleased. it was a little tiny bit fiddly because of the difference in fixing holes etc, i had to modify one gasket too as the hole wasnt inline, but i used gasket seal as well on both sides and got it all bolted up lovely.

was pretty cold, but glad I did it, sounds nice now, and feel solid underneath. The side bracket wasnt inline though with the body fixing, so thats only got one bolt now rather than two, but its rock solid so it should be ok!

as for the Dremmel, ill check the model i have, i have forgotten. to be fair, i think the one i have is only for light work, and i dont think that includes bolts. At a push, it should be ok on light body work, internal stuff etc, but i dont want to burn it out trying to cut a bolt!!

Good lad!!! Just in time for the white stuff hopefully

I've just finished outside wiring up my new spotlights on my bull bar and gluing the chrome piece of my grille back onto the plastic as it nearly blew off on the motorway lol
