    this is a guide how to replace the oil seal in the 16v distributor
    and is all so handy if you have to change the hall sender

    it has always amazed me how much a new or recon distributor is they start a about 80
    it is usually only the oil seal that wrong with them
    and the seal only cost 2.30

    hear are some of the things you will need

    * pin punch

    * hammer

    * scriber

    * feeler gauges

    * two sockets

    * Vaseline or oil

    first you need to remove spring clip round the distributor drive not all distributor have this
    DSCF1851.jpg

    then you need to punch the dowel pin out with a pin punch off the right size about 2.5mm
    you will need to line it up as below
    it all so pays to mark the shaft and distributor drive at this point

    now remove the drive and washers dress and rags on the hole thru the shaft
    and then gently drift the shaft out remove shaft and washers
    DSCF1847.jpg

    now using a scriber with tip bent with a short 90 degree bend like below
    DSCF1854-1.jpg

    remove the cap washer that is on top of the seal by putting the bent tip between washer and the seal then carefully tap it out
    DSCF1840.jpg

    now do the same with the seal you will have one side then the other to get the seal out
    evenly

    now you should be left with this
    DSCF1835.jpg

    now you clean all the parts and polish the shaft where the seal runs

    now you are ready to put the new seal in
    DSCF1836.jpg

    place the seal in the bore then tap it in evenly with a sockets just smaller than the bore

    tap it in till it is all the way home
    DSCF1838.jpg

    now you want to put cap washer back on line up the serrated edge with the old marks on the bore
    DSCF1841.jpg

    then tap it home with a sockets tap round the edge and not in the middle
    so not to distort the washer
    DSCF1842.jpg

    now place the two washers back on the shaft the fibre one then the shim
    then smear Vaseline or oil on the shaft
    DSCF1846.jpg DSCF1839.jpg

    make sure there are no rags on the hole of the shaft now push the shaft thru the seal
    DSCF1845.jpg

    put the washer back on
    DSCF1849.jpg

    then put the distributor drive and line up with the marks you made and line up with
    the slot in the body
    and punch the pin in
    DSCF1850.jpg

    make sure the pin is centred in the shaft then fit the spring using the feeler gauges
    to slide the spring other the slot
    DSCF1851.jpg DSCF1853.jpg

    you can now fit a new o ring the the body and fit the dust cover and rotor arm
    DSCF1857.jpg

    you are now finished and ready to refit the distributor if you marked it before you
    removed it you can just line it back up if not you need to re-time it


    the seal is 12x19x5 you can use single or double lip seals i used single lip

    distributor body o ring
    the o ring size is internal diameter is 37.5mm and the cross section is 3mm

    Great guide. Just speaking to these guys - are they the place you ordered from?

    There's a min order charge. Anywhere they can be bought from individually?

    Ah, I've got the inner seals now, two actually as I've got 2 to do.

    Where does the fibre washer come in? Can you pick up the relevant pic?
