    Both relays done

    Had a bit of a SNAFU event I wrongly assumed this is how relay went back together IMG_4625.jpg

    The red light was that the shafts were to short to pickup oil seals this meant I had put all my seals in the wrong way around IMG_4624.jpg

    found some clips IMG_4630.jpg I'm finally learning never throw anything away

    Had to modify my compressor with some flat plate as the spring kept rolling IMG_4632.jpg

    Should have removed cable ties first but I was a little nervous with all the pressure in the spring IMG_4633.jpg IMG_4634.jpg

    Second one was a doddle after I realised it wasn't going to fly apart in my handsIMG_4635.jpg gnarly end is at the top

    Oil funnel........ will let them sit overnight then top up if necessary IMG_4638.jpg IMG_4640.jpg

    Got my front half shafts fixed up.... one of the diff end yokes on the 24 spline had been flogged at some so I mixed and matched

    Started on front axles... first problem not enough gaskets

    IMG_4656.jpg then had to find fixings for swivel housingIMG_4657.jpg

    At some stage I'd given orderly storage the flick... IMG_4658.jpg IMG_4659.jpg

    Next my series 2 manual and series 3 manual differed on pre loads IMG_4668.jpg IMG_4671.jpg went with IMG_4663.jpg

    one side doneIMG_4672.jpg with no backward travel except adding and removing shims

    Cheers Paul

    Got front axle assembled replaced oil seal lands now I realise how easy it is to do, and I had some on hand

    IMG_4675.jpg IMG_4676.jpg

    Odd thing was back axle had a hex nut here but front needs stilsons to tighten .....not what you may have in your average mechanical tool kit on the road

    I thought that changed with Series 3, actually with the 24 spline hubs.

    Actually, looking more closely, that looks like a nut that has been modified to be compatible with a particular free wheeling hub.

    Both front and rears are 24 spline donated by a series 3 just seemed odd to me that front nuts are round perhaps they are for a specific free wheeling setup that's long since disappeared .
    If it relates front brake shoes and drums are wider than the rears

    I have a few s3 front axle nuts and all have been rounded but still castellated. BUT all have had free wheeling hubs fitted. Maybe modified to fit the freewheeling hubs as JDNSW suggests.

    Then those nuts probably are actually S3 nuts.

    Actually, looking at the parts book, those nuts were fitted to S3 from the start for 109s, and to 88s from June 1980 - up to then they had hex nuts. They also have a different seal arrangement to try and stop oil leaks with the round nut.

    Front axle finished

    IMG_4682.jpg IMG_4684.jpg

    Revisited the back axle to fit oil seal rings under hub cap and found no nut on 24 spline just a circlip

    I was getting confused with the 2a rear end I'd assembled a few days ago.....but I still think round nut is a bit impractical, but at the end of the day I suppose a good finger tight torque is all that's needed with split pin.
