Right,

I'm trying to replace the crankshaft front oil seal and to do this I need to remove the timing belt and pulley off the crank.......there's no space to get a puller in and the thing does'nt want to come off........whats the best way?

 

Help.............................PLEASE

Have you taken the radiator out?

Radiator, timing belt covers, coolant pipes (aluminium), crankshaft ancilliary belt pulley, water pump (gonna change this as well) and timing belt have been removed, just need to get the timing belt pulley off the crank........three hours i've been trying and its starting to p** me off.

 

Thanks for the prompt response

It will come off eventually or try finding a low-profile puller. I got impatient with mine and smashed it off, then bought an lightened underdrive pulley to replace it. Get some copper grease to put on the crank when you put the pulley back ;) Makes getting it off again a doddle.

Another tip seeing as your in the area is to replace the rubber hoses going from the block to the top rad hose pipe. These will be fooked and are more likely to go now youve moved them about abit. Not expensive, I just went to an auto factors and found some rubber hosing with the same bore.

You will need to cut it off if it is the timing sprocket that the timing belt goes onto. I did this about two months ago, I stay in Aberdeen if you need some help bud.

I had the same problem and couldnt find a slim enough puller anywhere, I dont know why they had to make the casting so close!

 

Some people grind them to open them up and get them off.

 

I managed to get a wedge in behinde and bash it off slowly, just be careful of the oil pump casing. I was replacing my pump so it didnt matter, but I didnt damage it anyway.

 

I think Turboz is refering to the pulley infront of the timing pulley in respect to the underdrive one.

 

If you need a new timing pulley they are about £25 from MJP

 

p.s get some penetrating spray on it, as they rust on cause when people change the water pump/pipes etc... it runs all over the pulley and they rust together. Copper slip is your friend when going back on, but not too much as you dont want it going on the new rubber seal you put in, as copper slip can attack rubber and its not something you wanna change too often

get a proper (short) pulley puller to get the main crank pulley of.

I personally use one like this :

used it on lots of pulleys without any problem..

 

to get the crank sprocket of, you make your own tool...eg like this one:

Thanks for the replies everyone, some good info here, i eventually tired of being careful, tried to ease it off with a cold chisel between it and the pump casing, gave up just as i reached for the sledge hammer. ended up making sure i could get one from MJP before using a dremel to cut a slot in it an spliting it open to get it to slide off. So tomorrow i start on the Rear Crank Oil Seal, whilst i wait for the front sprocket to come.

 

Stevie where abouts in Aberdeen? i live in Tarves

I live in the city centre but my zed is in the bridge of don. Got it in bits doin a bit of a build to it.

I wish I made one of those tools!

When the crank sprocket is really seized on its best to drill a hole through it and split it with a small chisel.a new one is about £50 iirc.

Eric! That's a top bit of kit, I'm making one now as I don't want to damage the sprocket, crank or oil pump!
