TheSamba.com :: View topic - Removing the crankshaft pulley from a DP1600 engine

Sat Nov 08, 2008 6:20 pm

I've removed the engine out of my 74SB got it on the engine stand and now I want to remove the crankshaft pulley. I tried pulling it but it's on there good (The nut is off...). So I bought a puller. When I tried putting it on it appears that on other engines the pulley must have a lot more room behind it then the bug does. I couldn't get the blot through the pulley holes from behind. So then I tried to put a nut on behind the pulley - still not enough room. Any ideas? I've never done this before but it can't be brain surgery. Thanks!

HEAT... apply some heat and two large screwdrivers and it will wiggle off.

Like Glenn said, it helps to heat the pulley.
The pulley hole expands with heat, making it easier to pull off.
You might not have the right tool.
This is the one you need.

I used a steering wheel puller with two 3/8" long bolts and nuts through the two "slots" in the front of the pulley. I've also walked them off with an air chisel from the rear (gently).

Good Luck!

Try two claw hammers and wiggle them alternately....

Do you have one of these or something like it?

Hit it with some PB blaster and let it soak in a little first. I have done the 2 screwdriver trick and it worked. After you get it off, consider putting on a degree pulley. I do this on all of mine anymore - takes the guesswork out of timing. And of course since it's shiny, it's good for 5 more horsepower......

lightly tap the backside of the pulley with a small hammer with one hand and rotate with the other hand.

Heat, lube, and a pair of big arse screw drivers or small pry bars are the ticket.

Are you trying to save the pulley, or just get it off??

You may want to give it a few sharp raps with a dead blow hammer as you turn the pulley to help things along. No dead blow?? A 3lb hammer and a block of wood will work.

Here is how I do it. Heat the pulley around the hub with a Mapp gas torch, when it's good and warm I hose it down with a good penetrating lube. Then I go find a smoke and the drink of choice at the moment and let the lube do it's thing for a while, If i walk by it again, I'll hose it down again. After things cool down to where I can touch things again with out burning my bare hand I clean up the lube on the pulley and re-heat and give it a few smart smack with the hammer, turning it about 120* after a few blows, driving it away from the flywheel. I then move onto the screw drivers or pry bars.

that puller is fine IF the pulley is not a tight fit on the crankshaft, or if you don't want to use the pulley again. that puller has a tendency to bend pulleys because it grabs on the outside edge.

the best puller i have found is the lower ones in this pic, Kukko #124:

i don't know the current price or availability of this tool, you might try www.samstagsales.com as they have advertised this tool for sale in the classifieds here before. you'll probably whine about the price, but it pulls stock pulleys with no problems and no damaged pulleys.
