Time, age, and usage has taken its toll on the rear silencer on the Ferret. Over the last year i have even noticed that performance is down a bit,and it was suffering quite a bit of back firing on the over run(air being sucked in so i was told).
Anyway, i was left with two options. Buy new. Or give the old one a temperory repair.The problem with buying new,was that their is only one person who has them in stock. And thats Bannisters at £350 a pop.It was then put to me that the easiest option was to give it a patch. And it would soldier on for another couple of years.Easier said than done. As it turned out in to a small mine field in other areas.
It was at this point that the job was turned over to Landrover guru Catweazle (Yes! remember him?. He is still alive) Who was ably assisted by Brains(Who just so happens to remind me of the wizend old woodpecker from Bagpuss)
First job was to remove the silencer which was a bit of PITA...............
It was a lot worse than first thought. And was rotted through along one side as well.
Rot was also found at the other end. The whole silencer was checked for thiness. And any weak parts cut out and replaced......
The blow was not only confined to the exhaust. But also to the flange that goes either side of the hull....
The flange was actually warped. And a corner had broken away.....
A new piece was welded in. And the area skimmed in order to give a flush fit......
In order to help with the flush fitting. Some nice tin gaskets were made........
While all this was being carried out. The boffins decided that there was way too much slop in the expansion joints. So these were shimmed. This reduced movement. But still allowed enough to prevent any fatigue in the system.
With the system now completed and its first coat of heat resistant paint applied. Its mounted back on the Ferret.......
The end result is. The Ferret now absolutely purrs. Performance is back up. And they have also tweeked the tickover.
Many thanks go to CW(John) and Brains(Tony) for the work carried out:thumbsup:
