i was driving in traffic today when my gearknob started rattling all over the place (3rd gear) it always did it a little bit, but when this was really noticable i thought it was going to jump out of gear. when i got home i got under the car whilst it was idling and there was the noise of a rooted bearing coming from the gearbox. so i was wondering whether its likely to be the thrust bearing or the input shaft bearing? the noise disappears when i push the clutch pedal in, which has me thinking its the input shaft bearing :(

if it goes away when u press clutch it could be input shaft, check condition of gearbox oil and maybe replace oil and see if it makes a difference...

they way it shakes around when in gear leads me to believe its fairly stuffed. i think ill pull the box out and replace both the input shaft and thrust bearings for good measure. unless anyone knows of anything else it might be? oh and i assume that the input shaft bearing is like other cars in the 34, that is you have to crack the case open to get it out, it cant be done through the front of the bell housing?

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      I was using the wiring diagram I have So 12.74V is coming into the rear Fuel Pump relay as I measured.  When I turn the key to ON im getting 0.6V to the Fuel Pump plug; which i assume is backfeed voltage and doesnt include the 12V from ignition power.  The rear relay is working and being triggered.  From the diagram I clearly see the rear relay 80 = Rear Relay going into the Body/H loom (R-27) 27 = Fuel Pump plug going into the Body/H loom (T-20) 40 = Short Connector (R-27) I'm reading 12.74V on the blue/black wire which is the power for the Fuel Pump   From this diagram I can see the Ignition relay goes into the front and up to the ignition  2 = Fuel Pump Relay <1M> (R-27) 37 = ING Relay <1M> I started from the pump using this reference Which the way I read it (referencing Nissan wiring color codes) is: Pin Wire Color Function 1 B/P (Black/Pink) Ground 2 L/W (Blue/White)        ECU Trigger 3 SB (Sky Blue) Fuel Pump 5 L/B (Blue/Black) 12V Constant Tested SB to SB on Fuel Pump for continuity - confirmed Tested negative on Fuel Pump to 12V battery and L/B - confirmed 12V Pulled the relay putting 12V between Pin 1 & 2 and testing continuity on Pin 3 & 4 - confirmed relay   So that has me looking at this part of the circuit to understand whats happening here...and im still confused. From best I can tell; the disconnect is back to my previous diagram; between Ignition Relay and Fuel Pump Relay...which yet again; afaik is where the immobiliser should.    Thats what I was trying to explain to GTSboy; im not trying to fix it myself; yet I seem to have to get a Masters in Electrical Engineering (while im busy doing my actual job of DevOps & Cloud Engineering) somehow.  I just wanted more expert opinions; or more so that what I tested is correct and proves it to something around that area; to go back to the alarm tech (for a 3rd time) that he needs to fix it. He keeps telling me its not the alarm. He lives on the complete other side of the city so i understand not wanting to make a trip but as I said before if its the alarm it should be up to him to fix it. But he's adament its not; even though I pointed out the FP was immobilised through the original alarm. To my mind; it seems that the ECU is sending the signal; but the ignition is not getting 12V down the line.

      Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.

      I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?

      RB20DE NEO smallbox clutch.

      So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'
