    damper/balancer removal 3800

    I'm getting conflicting info. Does removing the damper require a puller on a 1988 olds 3800?

    The pages from the manual that Cemax posted (see prior post on CPS Olds 3800) say: "The damper should pull off the crankshaft by hand"

    But that manuel is for a buick and a different year I believe.
    the picture looks totally different than what I got.

    Another post by Lynch Mob says you need a kent moore puller #J38197 which when I look up a picture looks like it bolts to three holes on the damper which are not there on mine

    It makes sense that it might pull off by hand because there are no holes on my balancer for a puller to bolt to.

    Can anyone shed some more light on this. Thanks

    Its based on a complete teardown and rebuild of Delta 88

    Cemax, I'm definitely not getting sick of someone trying to help somebody else. That is what these boards are all about. I really appreciate your input. Those pages from hayes are great and lead me to believe that I can just remove the crankshaft bolt and yank the balancer off by hand.

    I'm just seeing if someone had dealt with this specific job (removing the balancer). Just trying to get more input before I go at it again, so I can have the proper tool if needed. Thanks

    What do you mean a "special installer" , do you mean a tool to align the sensor? The sensor I bought came with a new bracket and the position of the sensor is adjustable the instructions say to use a brass feeler gauge and maintain .020" clearance.

    I don't feel this CPS is a difficult job to do.

    My only question is do I need a puller to remove the balancer or not. If so then how does it attach to the balancer as there are no holes for it to bolt to.

    I agree there is no substitute for a factory service manual and perhaps i will get one. I am however, in the mean while, trying to get info on the balancer removal from a tech or someone who has done this before.

    I am pretty sure you need the puller.I am GM Tech at a Buick dealer.I have not worked on an older style 3800 in awhile.We mostly see the new style 3800 series 2.But i am pretty sure you need the puller still.When i get to work tomorrow i will double check for you.The puller uses 3 real small bolts.If you look closely you will see slots on the balancer.Look inside and you can see where the puller bolts screw into.The puller bolts are 3/8" or 7/16".

    I just checked Alldata to see if they listed a puller.They do not list a puller.If you do not have air tools you are gonna need to hold the flywheel with a pry bar.Remove the balancer bolt,i think it is 15/16" socket you will need.Remove the bolt pull on the balancer and see what happens.It might just slide right off.Like i said it has been awhile since i worked on an older 3800.Good luck,let me know what happens.

    Thanks Lynch, and everyone else that replied. I'm gonna try to do it sometime this week. Hopefully the balancer will come off easily, if not I have a plasma cutter(kidding). I took the car for a drive after I put in the cam pos sens, and it still died. I'll let you know how it goes.

    yeah, I find chilton's better (and autozone online)

    See my other post below this one tittled "1988 oldsmobile 98 cutting off-no codes"

    Most people tend to agree its most likely the crank position sensor so I am trying that.

    I have a '91 park ave with the L27 3.8 engine.
    when the MAF died (no codes) it would crank, but die right away.
    most sensors you can diagnose following the autozone steps.

    Mine starts right up runs great then it will just die after about 15-20 min. It usually refires right away sometimes it takes a few seconds or sometimes a few minutes.

    unfortunately I see you need an oscilloscope to test your old sensor...
    if you allready changed this (and alligned properly - they're very sensitive) check the harness (if the wires don't rub against metal or other stuff).

    you may need to diagnose all the sensors you can and harness, if everything checks out ok, you may have a bad ecm or ignition module (but in those cases the engine would idle/run like crap all the time)...
    you may also want to search/post in www.automotiveforums.com you can find some answers...
