TD5 Injector help request

Hi all,
Does anyone have a TD5 Injector lying around? I want to know the thread size in the top that is used with the extraction slide hammer tool.

If someone has a broken one or one they don't want that they could send me that would be very useful indeed.

Many thanks,

You dont screw the slide hammer into the injector like with other types.
The slide hammer uses a special end piece that slides under two machined edges on the injector body.
You can use a small pry bar to carefully lever the injector out but dont lever on the solenoid body just the actual injector.

I've been chatting with the guy who makes the LR steering wheel pullers on ebay. He'll make me one given the right info, as I think there's a market for these. I just need an old injector to see how to design it.

At £250 each and the consequential reconfig of the ECM I think I'd buy or rent a tool rather than risk damaging one. The O'ring tool and the washer tool are easy, just need an injector to work from.

There's a thread on here where a garage couldn't get one out. As my main car I can't afford for the job to go wrong on me. I'm quite sure with your Africa experience it worries you less, I suppose I'm just being cautious.

Once you remove the injector clamp the only thing holding them in is the O ring seal.
I've taken mine out several times with no problems.
The special tools for removing and replacing the O rings and copper washers are a waste of money. You can do it with your fingers and a craft knife blade.
How much would the tool be from LR? It may be worth buying one and getting it copied. That way you have all the measurements you need. If you could sell them for a decent price I'd buy one.

Exactly!! I don't think we need the original tools, they'll cost a fortune judging by the design, especially the washer remover.

From your experience why is a special tool needed for removing the sealing washer? Are they a very tight fit? Does the sealing washer distort when you do up the clamp and seal itself onto the injector body?

For the O ring I was just going to wrap a single layer of masking tape round the injector and slide it on over that. (leaving the groove clear of course) that way it can't get any nick marks while sliding over the edges on the way up.

From your previous notes I quite agree about just getting the O ring off with a wooden or plastic tool that can't scratch anything. That's how I've always done it.

Yes the copper sealing washers do distort once the injector is tightened. They also get hard with the heat and can be quite a tight fit over the injector tip. New washers are a loose fit and will fall off the injector unless you use a small dab of copper slip grease to stick them in place whilst inserting the injectors into the head.
The bush mechanics merely remove the washers using a screw driver, heat them cherry red to soften then flatten them, before reusing. Needs must.
The O rings are quite tough but I suppose they could get knicked on the sharp edge of the injector body. Masking tape or insulating tape will protect them if you're concerned. The important thing is to make sure they are not twisted.
Removing injectors is not something you do often so spending a fortune on a tool that you may use only once is not my idea of fun. I guess I'm old skool when it comes to making do and the old adage Improvise, Adapt, and Overcome works, for me.

I agree with comments above you can make a simple tool that sits under the flats on the sides of the injector from a couple of bits of 3mm flat steel welded at right angles, you just need to be able to get a good grip to overcome the resistance of the o ring. If I can arrancge it I'll get a pic of one I made, cost nothing.

Thanks Steve, that would be geat. All info greatfully received.

I'll say this, the issue for me is risk. If I can't get the injector's out easily then I risk of not making it for work etc. while I wait for someone to turn up with the right kit isn't worth it. So the £20 or so quid for a tool is a no brainer, at least for me.

I can't understand why you cant hire these things.
