    Bearing Conditions

    Hi All,

    As part of rebuilding my GS (https://performanceforums.com/forums...gs-1220-pallas) I've been rebuilding one of my engines.

    I've opened up the bottom end to check the bearings, and I think we're looking pretty good.

    What do you guys think? I can get new shells, but its not a cheap exercise.

    Ken

    Clean the oil off to show full bearing. Did you check the clearances with plastiguage?. If all good go for it

          OK, here are the three bearing shells after cleaning. Running my finger across, I can't pick up any differences near the slight discolourations.
          I've got some plastigauge coming, and have a set of micrometers/telescopic gauges, so I should be able to measure the bearing clearance. The only issue is that the manuals and factory service books I have don't give a clearance measurement (just endfloat).
          I figure I'll pick something reasonable after a bit of reading - from what I've seen between 0.05 and 0.075 mm is reasonable.

          What do you guys reckon?

            whats a new bearing set cost ?

            guess its a balance of wear versus $ - and if you are doing 2000km a year versus daily driver


            but question may be academic before you check the clearance first inc crank main ovality

              The issue is availability - I can only get an oversize centre bearing, and normal replacement others; perhaps if I measure the bearings up I can find something that suits from another application, but i think that is a long shot.
              It will be a 2000km a year car, not a daily.

              Thanks for the advice.

                  If it’s a light duty road car of limited use I’d run them again.

                    Like he said, light duty car, run them again.

                      Thanks guys, I'll pop up the clearance figures when it comes time to put it back together.

                      Cheers,

                        I'd put those back in and never think of them again.

                          100% would reuse

                          I've put engines back together with copper showing and they were still going 12 months later

                            Yes, we tend to forget that bearings are a wear item with upper and lower clearance limits, we tend not to give any thought to reusing them because they are so cheap and the labour cost is so high, it makes sense simply to replace them. But for your own vehicle where there is no labour cost and/or if the bearings are expensive then there is no reason not to.
