Thread: Have I overtightened the oil pump bolt (TD5)?

Mate, relax, it will be fine, I could not get my 1/2" drive torque wrench on to the bolt so I tightened it until the engine started to turn over. That was 2 years ago.

Mate, I did mine today too, Mine was loose and and I replaced the bolt and did it up exactly the same as you, so if yours fails so will mine!!! I think it will be fine.

Thanks Robbo, I did manage to get my 1/2 inch torque wrench in there which made easy to over-tighten. I think I may have gone a little too far past the engine starting to turn over and thought I felt it turn slightly without the gear turning over? It that possible?

I'm contemplating removing the bolt before the loctite has cured and refit a new one or the orginal with new loctite in the morning, unless I get talked out of it.

I used the same method of torque wrench, started to turn the motor so its probably tight enough. Whatever you do, don't re-torque it after the loctite has been applied for a few mins. It may have set and you will make things worse by breaking the bond checking if its tight.

Thanks Jeremy, Just a little worried as I reckon I may have felt it rotated that extra little bit without the gear moving.

Saying that, I'm still able to get reliable clicks on the torque wrench at 27nm which tells me it's nice and tight.

I guess the post below has me a little worried. He was told his bolt failed due to being overtightened. As always I found it after the fact.

For goodness sake, if after 220,000 km's, nothing has happened, leave the bolt alone. Stop listening to the naysayers, stop being paranoid, it's all good, Bob

Your not alone. Had a go at my one last winter. Turned out the bolt was in good and proper but changed it anyway. Have a small enough torque wrench to get in there to do the new one up to spec. So probably the whole exercise was a total waste of time but with all the postings about loose bolts what choice do you have if you want to take your disco out bush.

your fine, I no longer go out of my way to check them but if I have to take the sump off for any reason even if its documented as done I do it anway
