Firstly I am trying to remove the cog off the crankshaft that the timing belt runs around. I used a pulley remover to get the large metal wheel off that holds all the ancilery belts. But for the life of me I cant see how to get that cog off behind it without possibly damaging it?... any suggestions really appreciated.

 

Secondly I have a full OEM gasket set but it does not seem to include gaskets for the water pump where it attaches to the block. It had some kind of liquid gasket on there when I took it off, does it get replaced with the same sort of stuff again?

 

Ta very much :mellow:

Loctite 5699 for the waterpump halfords 5.99

Thanks for that... I will get some tommorow. Any ideas on removing that crankshaft pulley?.

or this.

Drill the sprocket and split it if you dont need to use it again.Try to force it off at the oil pumps peril.Oil pump is over £100,sprocket is £40 ish.

Close but no turkey it is a cam belt cog that sits behind the big belt pulley. Thanks anyhows im sure someone on here knws a trick to get the sucker off.

Jimmer its the spocket that I need I have a new oil pump, is it best to just buy a new one?

For £40 might be the easy way....

I think I managed to get some wedges behind, but was changing the oil pump, so didnt matter it I damaged it or not.

 

Brute force and ignorance will prevail.

Forgot to put, or grind it off

Have a new one matey,i always get a new one when doing my builds,they are usually stuck solid and wont come off.Go on z1,s site,enter sprocket as a search and it will come up.copy p/number then ring Nissan main stealer monday :thumbup: Or if you need more bits add it to your next shopping list.If i had a new spare id send you it bud but i dont :sad:

Ok no worries I will buy a new one and I expect its best to replace all the tensioners as well?. I will get an order in Monday.. thanks

Yes, replace the tensioner and all bearing pulleys.

i did mine the other day. tried using a cold chisel etc behind it but it damaged the sprocket before it moved. they rust on the inside and its such a good fit it wont budge. drilled mine in the end and was no way near as bad as i thought. ordered one from mjp, was with me in a fewdays and was about 25 plus vat.

Yes I am going to change it along with all the bearings :blushing:
