Trumpet Removal - HELP

[Overhere]

Ok Folks, any ideas would be greatly appriciated. I'm fitting new carbon trumpets from ACT, instructions say put a 38mm tube or rod in and they will prise out.

No chance, I have a floor jack hadle that fits but no way. The instuctions also say heating the base in the oven will help, I'm pre-heating the oven now, anyone know what temperature cooks them the best so they are tender but tasty ! ;-)

My wife is giving me jip cos she thinks it'll make the food taste like petrol!

Mine needed a good few sessions in the oven before they could be wiggled and tapped out - three quarters of an hour at 220 C or so did the trick, finally...

The Smeg wasn't affected much, but the oven gloves I used for taking the base out again, were...

I simply used a blowtorch on each trumpet- no problems

Ok, so I heated them up for 15 minutes at 200, took it out and yes, it stunk up her kitchen. I think it did help to loosen them a bit, I had the base in a vice and a 3 ft bar wiggling and waggling back and forth, I was able to get a mm or so of movement but after several hours I was stuck again, they were wiggling but not coming out.

My wife wouldn't let me use the oven again after I stunk out the kitchen so I had to look for alternatives. I tried ice down the trumpets but long story short decided on to try something different. I drilled a hole thought the top of the first trumpet, put a bolt through, turned it up side down and put my pipe down and hammered it. It drove straight out. All eight, drilled and hammered, out in 40 minutes.

NOW, ready to glue the new ones in, I somehow thought the new trumpets came with adhesive, but no, can anyone tell me what kind of adhesive to use?

Thanks again

Waited for wife to go to out on Friday, put assembly in oven for 30 mins at 200, removed from oven and using pump pliers pulled out the trumpets took 2 mins to remove them all. Then left house and oven to ventilate for the rest of the day.
I have cut them all down an now need to glue tham in. There was mention on a previous forum about a high temperature glue to use.

Hi Chris, I guess I should have persisted with the oven, anyway, they are out, ruined but out.

Anyone remember or know of the name of the high temp glue?

[blitzracing]

Use JB weld, its a high temp epoxy- completely brilliant stuff, but get the slow stuff (24 hour setting)it can easily take the heat. Ive used it to hold an inlet manifold onto an air cooled engine at 130' no problems.(Oh and my trumpets as well!)

Thanks, I'm ready to glue so I'll give it a go. I've been trying to decide whether to glue all the trumpets in first or bolt it to the intake manifold first, only reason not to glue first is the trumpet tops make getting the socket and extender on with the trupet tops in the way

For what it's worth, here's how I did mine...

Thanks Woody, so far I'm doing the same thing, question is, did you glue the trumpets before attaching the base to the intake manifold, and if so did you use a socket U-joint on the torque wrench, or were you able to get the socket on the bolts w/o one?

Actually I don't have a troque wrench, was going to "wing-it". How critical do you thnk this is?

Thanks again.

I did glue them in before fitting to the inlet manifold, left them 24 hours to cure IIRC. That way I could trip any errant glue. I didn't need a UJ to fit it back on, the only problem I had was getting the plenum on over the trumpets and past the bulkhead grill thing.

I think that getting a good seal around the inlet manifold / trumpet base / plenum is all that is needed, I think you can get away without a torque wrench as long as you tighten up the bolts evenly...I used red seal around all the joints

Thanks Rich, I'm ready to give it a go.

What we do is clamp the base in a vice, with a 24" length of steel tubing (which fits inside the originals) we prise them out very easily without any heat, but without a vice not easy, in which case heat will help. any probs call us
