    In the process of restoring my Trabi I thought that I should replace the bearings for the fan even though they didn't sound that bad.

    I regret not looking in the manual first to see that it is recommended to use a custom puller and I ended up trying to use a 3 jaw puller that I modified to fit. It seemed to start working great.

    I didn't expect it to be a big issue and the pulley started pulling just fine but then I stopped when I noticed more resistance but it was too late and I realized that the jaws had started to dent the pulley. Crap!

    I will fabricate a proper puller now to finish pulling it but the damage has already been done and I am not sure if I can remove the dents.

    If someone has a spare or 2 in good shape that they would be willing to sell that would be great. I know I can get one from Germany hopefully but would like to save shipping time and expense if possible.

    Thanks!

    Ended up making a puller. Worked great!

    Should have done this in the first place... do it right the first time instead of doing it over! ;)

    Wow thats a great idea! I went through the very same issue, and totally ruined a pulley- it never came off(even when heated). Thankfully there was a spare fan assembly...

    Hmm, wonder If I could make that on my little Atlas lathe.... :rolleyes:

    Yeah, now my project is making something to press out the dents that I made in the pulley. I've got some spares coming from Deutschland but I still want to repair this for a spare.

    AbzieherRiemenscheibe TRABANT 03 23594 000  for 86mm outs. diam., air fan pulley..jpg Tim, I have encountered the same problem......and wandered if you MIGHT have done a drawing, with dimensions, etc....like a "blueprint", for your puller assembly? I'd be very grateful, if you had such a thing you might be able to send...then I can make one, on my lathe possibly? Presumably, you have a retainer of some sort on that middle nut and plate? Alternatively, could you QUOTE me for making another unit, with shipping??.... Many thanks. Ian (in the U.K.).

    NOTE:- My pic shows the original 86mm o.d.-type WORKSHOP pulley puller, for the cooling fan pulleys, supplied by IFA/Trabant, originally!!

    I'll see if I can put a drawing together for making the part and upload here.

    Even with a correct puller it wasn't an easy feat to pull the pulley, it was on there really tight.

    Even after pulling I discovered that it might all be for nothing since pulling the fan shaft itself is going to be a chore as the shaft is really tight on the bearings and the bearings are probably really tight in the aluminum housing. I really don't want to shave that aluminum casting pressing out the questionable bearing.

    Funny that about a week after I made and used my puller I got the authentic workshop puller from Germany. Always good to have a spare and options!

    Thanks very much for your comments Tim...and look forward to downloading a copy of your drawing and dimensions, when you make it available. Presumably, you made the unit, from Aluminium, by the look of it?....However, some notes re. materials used/recommended, would be good. Out of interest, from whom did you get the original German - type puller?....AND do they have any more, as an option?! Regards!
