OK, so I am a bit stuck doing my timing belt service today.

Managed to get the bolt out of the crankshaft that holds on the pulley but the pulley seems to be stuck fast to the shaft.

Any ideas how to backyard it without using a puller or whatever they are? Not a lot of room in front as I left the radiator in there. Don't really want to have to pull it out too...

try tapping it with a hammer...side to side.

or a lever bar on something hard enough (ie not timing belt covers ) and slot behind then try n lever off.


ive had some real tough ones at work that wont move with nething apart from a puller. so worst case scenario ull need one.

unless its an Auto i wulda pulled the rad lol

BFH, or perhaps abit of heat?

Tried a lot of hammer tapping, but very limited room to swing one.

Ended up removing the radiator, but only gives another 7 or so cm.

Then tried levering but not much to lever off.

Tried hitting lever with hammer but just did a little damage to the belt cover.

Went to try and find a puller but couldn't find one at first, was told to get a harmonic balancer puller but no-one I spoke to knew how to use one and I never had before either. None had any instructions and when I looked at it it didn't make a lot of sense for what I was trying to do.

Eventually found a 100mm gear puller (not knowing how big the pulley was but thought it was close - plus it was the biggest one that SuperChump had in stock. It is reversible but of course the pulley in question has no inner lip with which to lever from.

Now I thought that this puller thingy would be fairly straightforward, but was not. Discovered that the pulley is more like 130mm so probably out of the effective range for this tool. Still no instructions but had a play with it for a while and tried to figure out if the bolts creating pivot points in the arms should be free to move or not? Still not sure now. Wasn't real effective whatever the situation. There was then nothing on which to lever off with the centre screw thingy, after trying to pull it out levering off the inside of the crank pulley thread (hope that's metal in the end of there), I then found an 18mm 3/8" drive socket to use as a stopper and it kind of worked the trick. After a bit more hammering and levering and about 3 goes with this puller which mainly seemed to bend the arms where the 2 pivoting bolts were on each arm instead of move the pulley I finally got it. Took way longer than I wanted. must wait until tomorrow to get bearings for the pulleys now dang it.

One of my new year's resolutions is to find out how to use these puller thingies and them harmonic balanced pullerer thingummys

Check the condition of the Gibb key in the crank shaft, usually if they are real tight its because the keyway was flogged out of loctite has been used to make it better again.

is there 3 bolt holes in the Pulley coz that is another style of Puller which can be used.

Please explain in more basic terms for the Lay-Dazz.

That's the bit what the pulley goes on eh? Seems to be no sign of loctite anyway.

The puller should look like this...

A quick run down on how to use them...

Thats my 2 cents worth..

Yes, looks like that. I'd say it was just too small (though any bigger and it wouldn't have fit where I needed it.

What's with the striking? I thought you had to screw it with a spanner to work it? Was no room for that either anyway, unless I pulled the motor out!

You can get a different type of puller that you strike to turn the thread instead of a spanner, etc....
