exhaust replacement question

Post by turbodave » Mon Oct 01, 2012 12:33 pm

Hi, After an expensive summer of repairs, Billy decided I had not spent enough and the backbox dropped last night due to corrosion between the pipe and the box. I have just bought both back and middle section with a view to doing this job myself and thought I would get the sections off while I wait for parts to arrive.
On inspection of the joint between forward section and middle section however I notice what seems to be a spot weld attaching itself to the bolt and bracket. Am I right?...if so is there a good way to cleanly remove this? Cheers Dave....photo to follow!!

As long as you can get the nut off, you should be OK. I suspect that somebody has done that so that a spanner is not needed on the bolt head.

thats standard for some, it just makes it easier to fit the new one if the bolts are held in place.

cut the nut off with a special clamp on nut splitting tool, or grinder with a stainless fine cut blade and cut down parallel to the bolt so it cuts off one side of the nut, rotate and repeat if ness.

Cheers, they look OK..I will give it one more go tomorrow and then will resort to spending more money on a tool I will use once...and even if I need it again , it will be so long since its last use that it will inhabit the black hole at the end of the road called "Dave's garage".....NEVER TO BE SEEN AGAIN!!

Hi,

I had a similar problem when replacing my system - all bolts completely seized and I didnt fancy spending hours underneath with a hacksaw on my driveway.

So with a bit of waggling I managed to get the whole system (from cold start vaccum valve backwards) out from the back of the Bongo - however - you will need to take the rear bumper off, the heatshield, spare wheel and jack up the N/S only (to make space between the axle and the body). With a bit of care and not snagging the rear brake lines it all came out and I did it single handedly - you may need a short length of wood/handle etc to lever things over the rear brake pipes. I think I also undid one of the handbrake cable supports. Sounds like a lot but its not as bad as it sounds (you might get away without removing the bumper) - but took me an hour to get that stuff off and I'd rather spend an hour doing that that scraping my knuckles getting filthy and swearing at recalcitrant exhaust bolts. I've also found I have a nasty aversion to Plusgas penetrating fluid so anything that minimises the use of that stuff the better (works a treat though).

If you have an angle grinder then life should be a lot easier.... (guess whats on my Christmas list!).

cheers,

Steve
