easiest sludge trap retaining nut removals

[Guy Wilson]

I've just the easiest retaining nut removal for the sludge trap.. I was dreading it..
Pilot drill and then a larger drill, then a stud remover... 20 minutes for both.. It will never happen again I'm sure...

Those stud removers are cr@p - several sets in my toolbox and don't ever recall one getting anything out. They either break or expand the stud to make it even tighter. Far better is a remover I only came across a couple or so years ago - it's a bit like a short hexagon key. You drive it into an appropriate sized hole, and it doesn't break or expand the stud. Others have used a star drive and bashed that in - same effect.
Full marks though on getting your blanks out. I had to give up on one of mine. Tried the welding trick but that simply hardened it so even a carbide drill wouldn't look at it. Ended up leaving it in and extracting the tube from t'other side. ..

This design seems to be a lot stronger.

Still has the fundamental failing though of expanding the stud its screwed into, thereby jamming it tighter.

I like the "drill-it-out-and-smash-in-an-Allen-wrench" method. Has worked for me a couple of times.

Re-fitting
Should the retaining stud on the timing end go in a far as it will go or does it fit flush as in the picture below (the one with the flush end) .. Also what the best lock tight to use to secure it?
Thank you!

Screw it in flush with the cheek of the crank. Screw it in too far and you will cut off the oil to the big ends.

Yep, Easiouts.....crap in use but great for Spark Eroding companies.
Far better (than use Easiouts) is the fundamental engineering approach of drilling out using increasing drill sizes.

G'day Fellas.
At work we use these Snap-On extractors, but at $400 a set too expensive for my shed.

thank you Julian!

Tried several different varieties over the years but my set of Sutton ones in this gentle spiral form has never to this point failed. I had a set of very expensive (Snap On I think?) ones that were just an un twisted tapering square section with a recessed edge down the four corners. You were supposed to just hammer them in but they never worked once. They simply reamed out a nice shiny taper. The other type in the initial picture I have only seen snapped off in place although I think with subtle application they would work. The secret of success I've found is to go for the biggest possible hole with the chunkiest Easyout and to give up before the tool if things aren't moving. :)

Hi, I have removed many traps welding a big nut to plug.

Once i'd drilled the staking points i whacked mine out with an impact driver. I've put in the Allen head type since.
