VOLVO PENTA DP-E Stripped drain plug thread

[sniffer]

As per the title ....

I'm guessing helical thread inserts are probably a no go here. Has anybody any experience of this problem?

 

[colhel]

Oil drain? Why wouldn't a helicoil work?

 

[sniffer]

I'm thinking about the seal created by the o ring , between the top of the insert and the underside of the plug. I'm going to attempt the repair as it can't be any worse either way. I guess it just needs to be flush or very slightly below.

Is the hole a 'full' through hole or partially blind I wonder?

 

[colhel]

That's what I would do too, just wind it in so it's just below. I can't see the benefit of it being a blind hole, is the plug just a straight thread?

 

[sniffer]

The plugs have a small diameter magnetic stem on the end, after the thread. This forms a bit of a step. By 'partially blind' I meant 'lipped' I suppose, to match this step but probably not. It might affect the re-drilling if it were. I'll check that tomorrow.

Have a look at time sert thread repair inserts, they use a solid threaded insert that leaves the surface flush.

Wouldn't be able to 'press' fit those. They do look good though!

Re tap it .

Not sure how that would help?

 

[scottie]

Is it not an insert to begin with?

Could well be thinking about it. Will double check tomorrow.

They are not pressed in - you drill out the old thread then counterbore the top for a flush finish and tap thee hole out, you then wind them in with a special tool (you can buy a kit with all the items needed)

I have used them before with good success
