O-ring kit for injectors, have I got wrong? 700 1988

posted by  someone claiming to be Landin on  Fri Sep 3 10:17 CST 2004 [RELATED]

Hello all!
I am writing from Sweden and it has been a while since the last time.

I have read that one should change the seals on the injectors because they can get old and not seal properly.I bought four O-ring kits at the local Volvo shop, its Volvo number is 1346393.Does anyone recognize that number and is it the correct number and kit for a 1988 744 B230F LH-2,2?In every kit there is 3 O-rings, 1 yellow plastic cone and 1 small round grey plastic ring.

Why I am asking is because I started in the afternoon today to change the seals and those plastic things also on one injector only (to start with).There is only 2 O-rings on the injector that has to be changed, why was it three in the kit?The old O-rings didnīt seem bad at all despite that the car has 180 000 kilometers on it.The plastic cone was very hard to get of the injector, I canīt reuse it again because itīs destroyed now.

The injector tip and needle looked fine I must say, the cone was a little black on the inside but that was all I could see.I did spray on some electric cleaner although on the tip.

I have a feeling I have got the wrong kit for my injectors.The O-rings was complete the same as the old but the yellow plastic cone looks bigger and it is a bit taller on the height than the old one.The new grey round plastic ring which sits closest to the injector is about twice as thick as the old ring.

Maybe You can see the picture now, with the old things the needle as I could see was completely close to the opening in the plastic cone now the needle isnīt as close anymore because with a twice as thick plastic ring, a normal O-ring and the taller plastic cone at the end the needle gets longer away from the opening in the plastic cone.

This canīt be right or can it?Does anyone know and has anyone used the same kit for theirs 744 88?If I think about it seems like the fuel have a smaller chance to get through that very small opening in the plastic cone if the needle is to far away and that can not be good!

I will go down on Monday and talk with the man at the Volvo shop to hear if there is some misunderstanding but what do You think?

As always, I greatly appreciate all answers I get!

Bye
Mikael Landin

    The Volvo kit for my injectors had too many o-rings as well. I don't recall the size of the plastic tip (I did this about five years ago). When I removed the old injectors, they looked great as did the seals and it was clear that I really did not have to change anything.

      Thanks Ringlee for the answer.

      I found in the archive an another person with exactly the same problem as I have, he has put in a picture of the things in the kit and also a picture of the injector so one can see the problem all clear (link below).

      Very strange that Volvo sell these kits when it is only the O-rings one can use and even worse when one have destroyed the thin spacer and plastic cone allready, very bad indeed!

      I have to go down to the local car junkyard and try to pick out at least one healthy spacer from a injector (donīt think it is possible to save a cone without damage it) and try to use the new plastic cone.The hole at the opening of the cone is slightly wider also on the old cone than the newer so I probably have to drill it up a bit!

      I am afraid when the injector squirts the fuel it has smaller chance to make its proper way into the manifold because it first have a narrower hole and then the hole is slightly longer away then it should be.

      Much work and money for nothing I must say!
