Special 5-sided sockets

[eddie48]

I just discovered, while searching for a fuel leak, that the fuel pump/distributor where the fuel lines hook up, has 5-sided nuts holding the leaking parts on. Where can I find the right wrench for these? This is for a New Holland TC40D. Looks like it should be easy to replace the o-rings to fix the leak, but I have to get it apart first. Any thoughts?
Thanks, Ed

I did an Amazon search for five sided wrench. They do exist.

I used to have a couple for opening up pad mount transformers

Thank you for the quick responses. However....Those wrenches are larger than needed for this application. This is about 10-12 mm. Quite small. I ordered and just received the 5 socket (torx) set from Amazon. NO go. I think that the fuel injection people really don't want us into the pump assy.

Same here. I've only seen penta head sockets. Never saw box, open or flare nut wrenches.

That looks right! I will measure the nut exactly to be sure. Just found out how to measure from the flat to the opposite point. I will let you know tomorrow morning.

I thought this bolt had a male head, not a female? If female, try McMaster items 2722N11 and 2722N11, pentagon bits sized #6 thru #10.

I measured and the Amazon socket Mrmikey found looks like it will work! I just ordered it. Thank you all.

You’re going to want to use a hand impact and hammer to loosen them.. they are EXTREMELY TIGHT..

 

[eddie48]

Good to know.
Thanks. Other than that, are there any other problems I might face to replace the o-rings? It looks pretty simple on the parts breakdown.

Consider searching "tamper resistant nut wrench".

I had to remove a rounded off 4 sided plug from a water line that was inside a wall. Usually a six sided 5/8's socket works, but the edges of the brass where rounded off.

I found this at Lowes, and it worked great!!!!!

I'm going to have to get one of those. Looks interesting.

Folks always fear the back-out tool, but I've used more of them on more plumbing than probably anyone you'll ever meet, excepting pro plumbers, and found they always work very well. Part of that is that you're usually using the largest tool in the kit, when it comes to extracting a plug or snapped-off NPT stub.

It often requires grinding the end of the extraction tool down a good bit, as their length is usually sufficient to bottom out in any tee or elbow, from which you might be extracting a plug or thread boss.

Just a few weeks back, I accidentally kicked my pressure switch off the expansion tank tee, while doing some core drilling work on a stone wall in the corner of the boiler room where the well hardware sits. Always exciting, when the pressure switch suddenly loses pressure, and the well pump turns on, creating a geyser in your basement that's spraying 10 GPM right onto the 240V pressure switch that's now hanging from its wiring.

Extraction tool easily removed the broken nipple's thread stub from the tee, and grabbing another 1/4" x 3" nipple off the shelf, I had the whole repair completed in probably 15-20 minutes.
