Exhaust Spring Bolt parts

[sharleko]

Hi, new to the forum, so apologies up front if I sound a bit of a numpty.

First time assembling new Cat and centre pipe on exhaust on a 2005 Berlingo. When I bought the bolt spring fitting kit which came with the cat, there was a couple of parts missing. I'm not sure what these are called, but see some refer to them as 'top hat' washers. They go on the bolt head and reduces the hole on the cat flange before the spring/.

Please can anyone tell me the 'official name' for these two 'top hats' and if they can be bought separate anywhere (correct size). Thank you for any help.

There were two of these in the old cat flange, but so rusty, I wasn't able to get them out. Really need to know what to call them, so I can get a pair as it is holding up re-assembly.

Can you not order a new clamp and send the dodgy one back, or call into a Quickfit type of exhaust centre and match up what you have? They are pretty specific in size and you're unlikely to find them off the shelf in an ironmongers, or for sale separately.

They look different to what you normally get but as photo above shows your typical set, it's simply a washer shaped to hold the spring in place. If these are any good to you I can sell you a set for 4.50gbp , basically x2 bolts with washers and springs in high strength steel

Hi oilyrag, can't really send anything back as I have opened the fitting kit and the company I bought it from says they can't accept opened items! How are you supposed to check all is there? Was on the phone to them this afternoon, they said they would look into this for me, but haven't got back yet. I'm not holding my breath. Anyway, we have a local garage, not sure if they would be willing to help by just selling me a couple of these, but I could give it a go. 

Thanks for the suggestions mate

Hi Kokain, -your photo shows exactly what I have in the kit, so maybe I don't need those 'top hat' thingys. But, the confusion I have is I can't see how the spring can work without them. With the set up in your photo, wouldn't the bolt just pass straight through the hole in the cat end flange? If I set the bolt up as in your picture (and you are right as I have seen it elsewhere on the net looking like that) the spring just seems to be loose between the bolt head and the shaped washer which goes over the thread, but not any higher up the smooth part of the bolt.  Maybe I'm not seeing something obvious?

Would this be the right set up Kokain: Bolt and spring (on bolt) through cat flange, through middle section pipe flange, then the washer and finally small nut.  (so the spring is between the bolt head and the cat flange) and rest of bolt goes through the middle section pipe flange). That's the only way i can see there being any way to be able to compress the spring. I still can't see how the bolt head won't pass through the hole of the cat flange though as the holes seem too big?

This is what I have with the kit, the same as your photo Kokain:

Hey, if I remember correctly one of the pipe flanges has already welded-in washers so the size of the hole is much smaller, however don't take this task too serious. If both holes are too big then simply use a washer and problem solved. I don't even use the spring method anymore plus I have different easier to use clamps we talked about in different topic. If you are struggling to remember the order it goes here is a bunch of pics

p.s You don't need anything to go in between the flanges, no spacers etc. even if previously there was or you've seen somewhere something

Thank you for all your help mate Yes, think I'll just stick a washer on them and see how that goes. I think your right about the welded in flange washers, that is what i could see on the old cat pipe and thought was missing from the kit. Thanks for all the photo's -they are a great help as I am fairly new to this. I used to do a bit of bike mechanics years ago, but not worked on cars for a while. Cheers
