hey guys,

my DR30 (FJ20ET) blew about 3 alternators with the previous owner, and current one rattles badly ... i traced the problem to the crank pulleys or harmonic balancer or watever the proper term is (im not much of a mechanic haha)

the front crank pulley is fixed, but then the rear 2 pulleys that are connected as 1, one to the alternator and one to the a/c pump, i understand these are meant to 'float' slightly on the shaft, but mine are worn or something inside and move heaps, as in they move and hit the block and hit the crank pulley (up and down entire shaft of movement)

as such, one of the pulleys is badly ground away on 1 side from scraping on the crank pulley, and the alternator's blowing bearings pulling the thing into line all the time.

i was just curious if anyone has had similar problems? im a car mod nut, so i was curious if their are any after market pulley kits available to replace my worn pulleys with? or is it just best to try and get hold of second hands pulley and shaft bearing or watever it needs?

i know GFB do pulley kits so i checked their site but they have nothing for FJ20, so just thought id query if anyone else has had similar problems and knows of aftermarket pulleys or the like. I always try to upgrade when i break something ! ! ;D haha

im in perth btw ..

cheers,

ant

      Por que no los dos? At least my euro brawler is reliable - unlike the JDMs I've had. Sheraaz you look familiar, did you ever come to an SAU VIC meet aaaaaages ago?

      Drove to Cape Schanck to try to get a nice clear southern view over the ocean to see the lights a couple of days ago... instead got crappy cloud cover. Photo of a diorama of Hong Kong street scene. Taken on an iPhone 13 Pro Max.

      R32 GTS (RB20DE) Injectors Replacement

      Stock RB fuel pressure is near enough 43.5 psi, so the latency in that table at 31.6 will be close. You can see that 7 or 8 psi equates to about 0.4µs extra latency. So if you wanted to interpolate between the 31.6 and 39.9 psi values you could say you're going up about 2 psi out of those 8, so add about 0.1µs, which is barely worth talking about and is quite possibly wrong because ideally you would fix the latency while running at the appropriate conditions on the dyno, with a wideband sniffing its butt.

      The pressure, is what you set the fuel pressure to. If you have the factory fuel reg, you'll need to find the factory spec. I don't know it off the top of my head, but someone else might.

      Belt flex under throttle

      For others, what GTSBoy states here should be paid attention. Why? Well lots of people play with different engines, and they LOVE to change things like remove AC, or steering pumps etc, and it lends to them needing to move the tensioner too. You want your tensioner, particularly those that are sprung or hydraulically tensioned, to be the first thing after the harmonic balancer, or technically the "last" pulley in the chain. By saying last pulley, I mean look at the direction the crank spins when the engine is running, follow the belt from where the crank is pulling the belt FROM, and keep following that until you're between the last pulley/accessory on the belt and about to reach the crank again, this is the spot where you put the tensioner. This is the area that will always end up with slack. This is worked out exactly the same way for chains too, as the physics is the same for them. The crank pulley is where all the force to drag the belt around comes from. You will never ever get rid of the slack that appears, especially under load. The tensioners job is to keep the belt loose enough when stationary that there shouldn't be out of sync movement in slow movement, and then be tight enough when running, that the belt can't jump off any gear and get damaged. Too tight, bad things happen, too loose, bad things happen. Have a tensioner (mainly sprung/hydraulic one) in the wrong spot, it can't actually do anything about keeping the tension.
