Im in the middle of changing my timing belt and cant remove the drive belt,alternator and P/S. Is there a certain sequence of going about this because i keep tightening the belt but the reverse is doing nothing at all.

Iv undone the hinge bolt pictured in the second picture. The two bolts im confusing of their functon are in the first picture.Ive undone the short belt, and tightned the long one and it pulls the alternator back essentially tigthening it. Help want to finihs this early if possible.

so i managed to take the alternator belt off by removing the water pump pulley. Anyone know where the hinge bolt for removing the A/C, Power steering is?

Would undoing the tensioner circled loosen the power steering?

I'm not familiar with 34s but from that picture it looks like the power steering and ac compressor belts are desperate..

Your power steering should pivot closer to the block so you can remove the belt

That idler you have circled should be able to be loosened by the front bolt

Not sure why you couldn't get the alternator belt off.. It's just a matter off loosening off the two bolts in the picture as well as the bolt that it pivots on..

To make them tight again use a lever bar to get tension

To remove the power steering belt,

loosen the 12mm tensioning nut below the pump on the right hand side. (on a long thread). Take the nut 3/4 of the way down the thread not off.

slacken the tensioning thread which is the 12mm bolt pretty much below the pump(follow that long thread back to the underside of the pump) the bolt sits the the adjustment slot.

slacken the 14 mm nut above the pump behing the wheel, can be seen in you pic. once these are slack push the pump downwards and you belt will be ready to pull off

To do up again:

Fit belt

Pull pump up the take the tension

Tighten the tension thread bolt

Tighten up the tensioning nut on the long thread and tighten to the required deflection.

Tighten the 14mm bot above the pump.

Th alternator is essentially the same there will be the two bolts that are used to tension and 1 bolt to anchor the hinge.

Undo the nut the nut that looks like its going through the long tensioning bolt.

Undo the bolt that anchors the hinge (stops you from moving the alternator

Undo the tensioning bolt the alternato should loosen up.

I just did this whole process on the weekend twice but that was on an r33,

so to add to the above, theres two bolts for each, you want to loosen both of them, so both bolts turn anticlockwise, its the long threaded bolts that help to do the final tensioning by tightening them. the A/C BOLT is under the bottem pully wheel, so have to get under car to see it.

when reasembling it, make sure the timing belt cover is on properly and firmly or else it will rub on the harmonic balancer and sound terrible. :yes:

      Front LSD Quaife , how streetable ?- QDF3L Owners

      By joshuaho96 · Posted

      Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?

      The FD RX7 is the best looking 90's JDM car

      in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.

      I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.

      If they just called it the "Mazda Tiffany", it would have been spot on.

      Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
