1273738 2012-05-05 08:40:00 Currently mum's is borked, tl;dr cam belt pulley came off, belt split, etc etc.
Managed to get a new one on, but not sure what order it goes round two of the pulleys. (since it came off before I'd ever taken a look at it)

Can anyone in the know help?
(Or anyone with a pulsar perhaps post a pic of under the hood?)

Would be immensely helpful, thanks.

1273739 2012-05-05 09:12:00 What year, what engine? Are you sure it's not an interference engine? Alex B (15479)
1273740 2012-05-05 09:36:00 1995, not sure of the engine, I just know it's got 'nissan' on the block. No clue what an interference engine is either.
Googling reveals it's called a serpentine belt. Not a cam belt, as my friend called it.
Pologies there.
I'll edit the OP in a minute.
Just had a thought though, looking at an exploded diagram of another pulsar I found. The wheels I'm not sure about it wrapping around is the alternator one and the one that gives the belt its tension. Given that they're going to spin the same direction regardless of whether I put the belt around the tension pulley then the alternator one or the other way round, will it even matter?

It basically looks like the one in this image with the air conditioner.

1273741 2012-05-05 09:39:00 Google Image Search (www.google.co.nz 0..0.0...0.0.S8fhQ3ugpnY&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&fp=4efffc0d311b36f4&biw=939&bih=433) might help. May want to include engine serial. kahawai chaser (3545)
1273742 2012-05-05 10:02:00 Well here, I took a picture. All I need to know is if I've got it looped around the shiniest one the right way round, And yes it's not sitting on it right at the moment since it's loose because the shiny nut is the wrong thread.

edit might help if i put the link to the damn picture in. i1218.photobucket.com

The engine itself is a twin cam 16 valve or summat, not sure of the exact serial, I can have a hunt around tomorrow morning. I'm thinking tomorrow I'll simply find a nut that fits somewhere, fire it up as is and try again if it explodes in my face.

Wow I thought I'd never be one of those sorts you find in the tech help threads. 'what is windows? what's an IP address?'

1273743 2012-05-05 10:25:00 Being a Nissan it doesn't have a cambelt but a camchain which you cannot see as it is all covered up. Basicly the belt that busted was as the old school would call, the fan belt as in days gone by that belt use to drive the fan for cooling the radiator water, but todays cars have an electric motor for doing that.

1273744 2012-05-05 10:32:00 The older Pulsars were an interference engine, so if it is of that age and the cambelt has slipped, it's quite possibly got bent valves. Hopefully that's not the case, but at 1995, I'd fear it is - is it a 1.5 litre, 1.6, 2 litre? If we can get the engine code we can probably determine whether or not it's an interference engine.

For reference, "serpentine belt" refers to the design of the belt (multiple rows of texture/ribbing type), whereas "cam belt" refers to the task the belt performs. Most if not all cam belts are serpentine belts.

Edit: Trev ^^ Some of the older Nissan's did have a timing belt, not chain, so until we know which specific engine it is, it's hard to be sure.

1273745 2012-05-05 10:39:00 I have Nissan Pulsar sitting in the back yard, approx 1989, if you still need help can post picture tomorrow, looks very much like the one that you have posted by the way. zqwerty (97)

My parents had Datsun 1600s and Datsun 180bs which all had cam chains.

1273747 2012-05-05 11:23:00 I'd say it's something like a GA15D or possible SR20 if it's a gti. Either way it looks like you have the belt pretty right there in the pic, but you will have to tighten it using what ever tentioning system they use. Some you swing the alternator out to tighten, others you undo the center bolt on that idler bearing a little (the pully that the belt backs on to rather than having the V slots) and then there should be another bolt to slide the idler up and down to adjust the tension on the belt (remember to do up the bolt in the center of the idler again.) The belt should not be super tight, as in no movement when you flex it, but still fairly right....kinda hard to get across what I mean but hopefully some of that makes sense. Alex B (15479)
