TD42 crank pulley removal...w.t.f!?!?!?

Post by Gabriel »

Hi all,

I'm in the midle of supercharging my td42...(finally!!!). So I have to fit one more pulley. Problem: the existing pulley dosen't want to came off!!! So I tried with a press, but I only manage to broke the pulley (not a problem, as I want to install new alluminium ones anyway...)
Now I checked with a friend of mine, working for Nissan and he sent me the page from the remanufacturing manual, saying that "you have to remove the nutt, putting it back-face ...and smash it through a wooden piece!!!

Anyone knows woh to do it?!? Anyone did it so far?!?!

Any advice will be highly appreciated!

Thanks, Gabi

Remove the nut--lock the flywheel with a flatblade screw driver through the starter motor opening--turn the nut around--then tap or hit the face of the nut with a soft faced hammer. This SHOULD release the cone from the center of the pulley......

OK..

I rebuilt my TD42 last year.. and its just a memory ....

I had a LOT of trouble removing that harmonic balancer pulley nut....

But if you have it in the car.. it may be a lot easier.. as i had to have someone hold the flywheel with a breaker bar while i had another breaker bar at the nut and belted away with a hammer.

If i remember.. the balancer was done up to 350 nm's of torque which is fairly damn tight... and a pain in the arse in removing

It may also be possible to stick a breaker bar into the chassis rail and put the car in neutral and gently crank it over until the nut losens itself. - Make sure the engine turns the correct way (which i think it does - cant really remember - been ages) .

And what woop said reminds me that i had a simliar problem with the cone behind the nut.. Sorry im not that much help..
