alternator pulley splined tool

Anyone know you need just the splined tool with the bolt head you turn with a socket -OR- if you need the same tool but with the long hex/torx bolt down the center.

You need the special tool to do it on the car. If the alternator is off of the car and you have the splined tool and use and impact gun it will come right off. To torque it properly you need the hex too. Why are you removing it? This is the one I bought.

that kit looks like it is ready for anything. so i can get the old one off with just the splined socked, but need the hex to properly torque the new one. This sounds like installing the top hat nut on struts where you have to use a allen key to stop the strut rod spinning while tightening the nut with a separate tool.

replacing the pulley because the old one is seized, it does not free-spin in one direction as it should. I've also got some belt related bearing noise and so far the belt tensioner and idler pulley replacements haven't solved it, this pulley is next on my list.

Mine was siezed too. The symptom was two knocks on start up. I replaced belt and tensioner with no change. I forget who on the forum told me to check the pulley. I got the replacement pulley from getbmwparts.com and the tool and everything is good.

cool. i get a clunk on startup but i always figured it was motor mounts, would be nice if that went away.

It will. I thought it might be mounts too. If you pulley is seized, that is your know noise.

got the tool in today. no plan survives initial contact though...

the splined part fit my valeo pulley, the shaft with the torx looking bit did not fit, it was made for a bosch not valeo. no worries. i can just remove the splined socket and use a screwdriver to wedge the alternator guts from spinning.

bent the shit out of the screwdriver and gave up on that idea.

found out that i could fit an allen wrench down the center of the splined socket. tried that for an hour and had nothing to show for it other than a nice twisted allen wrench that now resembled a barber pole.

so im down a screwdriver, and an allen wrench.

at this point i am bothered so i broke out the blow torch. its out of propane. no worries i have 5 of the camping propane tanks, they fit the torch fine. applied heat for a bit. nothing came out of that.

ran out of penetrating oil. used some gun cleaner rem-oil, seemed light weight enough. let it sit, beat with hammer. nothing.

went thru toolbox, found impact driver, old school tool i bought like 10 years ago and never used, came with 5 bits. You whack the end with a hammer and it acts like an impact wrench. couldn't find the adapter to put a socket on it though. (need a 17mm socket to fit the splined socket).

went online to look at women and then remembered that there is no adapter for the impact driver, instead you pull the collar off it and it reveals a 1/2in adapter that you can directly stick a socket on, ok we are in business, spent 10 minutes whacking this impact driver with a hammer, the pulley finally comes loose. replaced and torqued the new one with a torque wrench.

then the plot thickens. while attaching the 4 alum alternator bolts, i drop my 3/8in extension and 11mm? socket into the belly of the beast. Use the magnet wand to get it back out. I felt like a hero. Then no shit, next attempt the freaking socket fell off the extension and has disappeared into another dimension apparently because the magnet wand cannot find it. im not removing underbody stuff to find a socket, will grab it next time i do the oil.

reattached alternator, airbox, fired up the car, sounds better, no weird noises and smoother idle sound.

I'm down a screwdriver, allen key, and an 11mm? socket.

still more fun than sitting at the dealer for an hour and getting ass raped.
