@Spac I truly do not understand how the car was the way it was. The passenger-side tyres were at something utterly insane like 55psi, and the driver's side were at 12psi.

Also, the rear right tyre visibly wobbled (and by god did it make the car shake). I was driving behind @DecimalDuck when she took it to the servo for fresh fuel and the tyre wobble was a sight to behold.

@Major Ledfoot we went with 205/60R15. We used the spare tyre (which was a factory original) as the reference for tyre size, it had a 185/65R15 if memory serves.

Knocked this difficult task over. Also replaced the alternator bushings and the fuel flap hinge and the belts.

Checked the timing belt as the PO said he replaced it but the PO didn't even have the crank pulley torqued so figured it would be worth checking, and the belt is on backwards ? so now it has to be replaced.

The steering rack is currently with Sydney Drive Shaft having its seals replaced.

Interesting - didn’t know the timing belt could be put on backwards?? I assumed as long as you put the smooth side out it was OK! :)

    I don't know if it can. I do know that it has arrows on the belts to indicate which way it goes on. That could just be for the sake of timing marks on the belt, but I don't know that for a fact, so the only sensible thing to do is treat the belt as compromised, I think.

        I think you should be OK but pretty easy and cheap to replace the belt and allows you to check to see if the tensioner was replaced when they did the belt too.

          Pfft, it’s a Redblock - just carry a spare belt in the boot.

          I once pulled the belt off a 244 that was about 10mm wide. Someone had installed the front belt guide on the crank pulley backwards. It quickly trimmed the belt down - and filled the timing cover with rubber and fibreglass...

              Not my car, I'm not driver, driver isn't a mechanic

                I know. Serious levels were low in my comment.

                There should not be any difference whether the belt is backwards or forwards, even in a round tooth pulley engine.

                The only difference would be in the lettering and the alignment marks, which whilst not incorrect, shows a lack of attention and ham-fistedness

                Speaking about the crank pulley bolt, its torque is 60Nm and a further 60°

                Do not use an impact gun here! (for removing or installing) Ask me why.

                You need the special tool to do this properly, I have one if you'd like to borrow it

                Okay so I tore down the timing belt assembly because frankly I didn't trust anything about it after seeing the belt on backwards.

                The crank pulley, which was loose when the car was picked up, has been damaged on its mating surface. The crank is, thankfully, harder than the pulley, and is not damaged.The locating key on the crank gear has sheared offThe timing belt is a square tooth belt and the gears are round tooth gearsThe tensioner was not replaced and the bearings are totally shot

                Anyone wondering why the belt being on backwards is a problem - you have to understand, if I look at the work someone else has done and they can't even do it right enough to put the belt on the way the giant arrow says to put it on, they clearly cannot be trusted to do anything correctly and the list of total fuckups above is testament to that fact.

                The belt installer probably (more like definitely) did not use the special tool to hold the vibration damper, instead they must have thought of more innovative ways or they were lazy and used an impact gun

                  2. The locating key on the crank gear has sheared off

                  Found PO had done that on The Beever.

                  3. The timing belt is a square tooth belt and the gears are round tooth gears

                  Whoa. That takes some forkery.....

                  I dunno, it sure felt like finger tight foot pounds. I spotted it pretty quickly as I could feel the engine vibrating strangely, and he said he must have forgotten to tighten it. Luckily, in spite of having changed it a couple years ago, the car had since not been run save to move it from one lawn spot to another

                    Picked up a new rack this morning. Old one had rust inside + failed seals. $440 from Sydney Drive Shaft in Kings Park

                    I've never used anything but a impact gun for the crank pulley bolt

                    Never had a single issue

                      Everything installed no dramas. Have hand bled the rack as much as possible, final bleed will need to wait until @Philia_Bear rocks up tomorrow with some parts for the timing assembly. Otherwise the car is good enough that next step is to hand it over for inspection and see how it goes.

                      We have new brake hoses but I'm time-poor at the moment and the old hoses might pass so I'll leave them for now.

                      If you want to try, bring your slimmest gun with you tomorrow. Otherwise I just use the rope trick, which I've also never had trouble with.

                          Never put a foreign object between your piston and head.

                          Especially when subjecting the crankshaft to over 200Nm

                              It's fine, honestly.
