    i have to admit the 3 screws of the hall sender were a pain too. but no fiber-gasket was damaged. they didnt need to be changed.

    this is how i removed it. i needed a screwdriver.
    look at the 2 holes. if they werent, than my distributor would be filled up with oil.

    the seal arrived, but i wasnt there. unfortunately i didnt take pictures of fitting the seal :(

    i myself tried putting the pin. it was really hard till mr. Visi [pronounced vi: si] taught me a trick.
    this is an industrial fixed power drill, and this is abrasive paper

    if it is the same, than you could use the entire ABF distributor in the KR engine?

    everything tighten well, and fired up the engine. everything looks so good. i can feel the engine run smoother maybe because of the new rotor. thanx for listening , a excuse me for the bad english. its not my native lang.

    idlirp-great addition to the thread there,good job

    john- i was thinking more of the hall sender rather than the whole dizzy,the on in the pic looks very similar to a KR one

    ordered a 12x19x5 from a different supplier and its still very tight to turn the shaft,is there any chance the seal was originaly imperial i.e 1/2 x 3/4 x 1/4 which is 12.7x19.049x6.35,this would explain why A,the shaft is tight,B the seal went in the body without having to tap it in and C there is a gap under the sea at the bottom of the recess of the body

    the right size is ment to be 12,5x19x5

    the seal was tight in the distributor i did
    i think need to mesure the bore on you distributor and see what size it is
    what make is it bosch
    it may even just be worn

    yea its bosch ,im more concerned about the ID,its just way too tight,OD can be sorted as the washer taps in over it,if i can get an imp seal ill try that,i doubt the dizzy is worn,i have like 5 dizzy bodies here and all the same

    just thought id add this pic of shim order from ABF as shown also in post 41 ,but in this you can see the top fabric washer is on its own and fairly wide,as opposed to a KR one that has a metal shim and a fabric one

    the od of the seals i have mesure 19.16mm they do say sc 12x19x5 on them
    what size do your ones mesure on the od
    as mine where tight to go in

    when you say too tight have you used any lubrication on the seal and shaft

    mine was at bit tighter to turn but not that bad i could turn it by hand
    they dont spin free if thats what you are thinking

    cant say as i have no vernier gauge,i did use a smig of engine oil on it and made a reasonable difference,but im comparing it to the old one where you could spin the shaft say half a turn,but this one has a lot more resistance,and to the extent removing the shaft has distorted the very top lip of the seal

    it shoud not spin free it only did that with the old seal as they where knackered

    are you using the twin lip seals if so and the outer lip is distorted dont worry to much about it
    as it is only a dust seal
    its the one below that seals the oil
    i used the single lip seal as the twin lip will be no better in this sort of use
    its not like you are going to get much durt inside the distributor with the cover and cap on

    hope this helps:thumbup:

    right ok so it all appears to be ok then ,i shall carry on building it then :thumbup:
    yes its the twin one and its only the dust cover thats distorted,i have just also tapped that washer down a bit,the one that goes over the seal,seems to have mad a bit of a difference too

    thanks
