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.

              Update: Ron needed a new AMM desperately, and @Philia_Bear helped hook us up with that and some new windscreen wiper jets.

              Yesterday I drove Ron to get blue slip from Sandy's Auto service in West Ryde. It passed blue slip, drove to get it registered right away. Every dog bites 47 unicorns ?

              @jamesinc Put the plates on last night.

              There are still more things to do but at least it is driveable and can legally be parked on the street now.
