Help, how do I remove....

[jdl25]

These plugs?





These are Honda Accord Transmission (BAXA 2001 Accord) valve body caps. Some of them are not so bad and they are easily taken out. Some of them are so tight that it is unreal. There is very little to pull on or push on. I have tried warming the valve body slowly, I have tried using some reverse snap ring pliers with ground ends to grab from the outside face cavity.

I have gotten a lot of them out, but the last few are so tight that I am not sure how to get them out. The manual does not address this. Once the caps are out the valves fall out. They are in great shape but the caps are so tight it is amazing.

Thanks for any help...

Try one of these:

1. Chisel in the reverse direction.
2. Hammer a square rod in the hole and turn it out.
3. Put a pipe wrench on the outside and turn it out.

They are not threaded, some I can twist till the cows come home but they wont come out of that cylinder... Thanks for the look though

Do you have to save them, or can they be damaged when removed?

 

[LXCam]

Are they a press fit or slight interference fit with a snap ring on the inside for retention.

 

[jdl25]

They are suppose to be reusable. They valve body is a delicate piece with super tight clearances. I never thought they would be this tight.

I'd try some compressed air with a soft tip blow gun in that port first. If not drill and tap and thread a bolt and pull or use a mini slide hammer

 

[jdl25]

I had tried compressed air with no luck... I think I may try the tapping idea.

There is a retaining clip on the inside of the valve body. It is in the first "cavity" you take that out and the plug has nothing else keeping it in. (Except friction in this case)

If you have a way of checking the temp, more heat, but don't let the body exceed 240 degrees. So keep a close eye on it.

If you can toss those and install new, the bolt and slide hammer will work as mentioned or build a little bridge to pull it.

I found a parts diagram there are clips holding them ? No the right car but try to find yours

 

[PoorOwner]

Also if you use a can of compressed air upside down and spray the cap, it might shrink it enough to pull out easier

 

[jdl25]

The clips are easy to get out, taking a look at the price for similar caps from the link in PoorOwners post motivates me to successfully remove and reuse these

This is on my list of things to try! Great idea.

Maybe try to heat valve body up in a oven, then remove the plugs.

 

[jdl25]

I was thinking about heating the valve body and then trying to cool the plug with the upside down canned air...

240°? Why?

I also suggest baking in oven and then quickly removing and using upside down can of compressed air. Get a helper, plan each step out and do it together.

I've always had good luck with a hammer and chisel if I round them out. I work on forklifts and the drive units always have these little buggers for check, drain and fill holes

A small pair of vice grip pliers if there is enough of a lip on the outside. Loosen it first by heating it up and then cooling it with a wet rag.

I have a pancake girdle (I got from Goodwill store) for just that purpose.
I have removed steel items that are pressed into aluminum buy blocking it so that, when it is hot enough, the part falls out (down). It takes a while, but it is a more controlled heating than a propane torch.
Second choice would be a hot air heat gun. HF has a 1000 watt that would work nicely,
Third choice - the nuclear option - drill and thread it and pull it out. But, that may pull aluminum with it and ruin the bore.

 

[My Old Tools]

I would drill and tap just the depth of the opening. then use a puller with local heat.

 

[myredracer]

Don't think it would be a good idea to user a puller or rotate it without heat because you could damage the inside surface of the hole. Maybe also use some cold spray on the plug after heating the whole piece.

What does your Haynes manual say to do? You do have one, right? "Removal is the reverse of installation"....

For a few bucks, maybe taking it to a machine shop is the best approach. I've gone to a local machine shop a few times with little things like this and they haven't even charged for it.

Might not be of use for you rightt now but I kept a product like this around for different uses, it will freeze small items in a few seconds. We used it mostly for detail work. http://www.amazon.co.uk/dp/B008LBA8LQ/?tag=atomicindustr-21
