as you can see the ends bearing are good but the inner bearing are gone! they are std stamp`d

and also the thrust washers are gone,,to much play

while i was under the car i checked the big ends bearing and i need a set of them also---std has anyone got a set to sell?

Why would you want to mix and match old (with unknown levels of wear) and new? Unless you fancy getting under there again to replace them all sooner than is necessary.

[nicmk1est]

right,,il go for full set main bearings

[Nick Jones]

Quite normal for the inner two mains to show more wear than the outers.  They take thump from two cylinders.  Replace the whole set seeing as you've already dropped the front main cap.  I've been known to check the rear main and if it's still grey, leave the front well alone (as it's usually the least worn of the 4) to avoid the aggro of disturbing and re-sealing the bridge piece at the front.......

BEs should be changed as a set also - imagine they are fairly coppery looking if the centre mains are like that.  You'll probably have to settle for County/King HD tri-metal though.  VP2s pretty much gone now.

Is yours late enough to have the bigger bearings?  Mk 1s come in two flavours so take care!

Cheers

Probably because he is wondering if the journels are worn.

[nicmk1est]

hope not ??),,,there was no signs of wear or marks on the journals-just bearings gone

[Nick Jones]

Don't reckon they'll be too bad - I've seen MUCH worse bearings than that, replaced them and all has been well.  Question I'd be asking is which one of those was causing a knock.....

Nick

[nicmk1est]

most of the knock was at the front of engine,long screwdriver to ear,,soon as i heard it,,get full bearings

[nicmk1est]

today has been a good day------first start after new full bearing installed,,,runs sssswwwweeeetttt,no horrid knocking,happy days are for now,,,mot next ;)   thanks all for info and support(fuel and matches not used)

[nicmk1est]
