#7863 Grease Joint Rejuvenator® Master Kit (Patented) - for Flushing Out Hardened Grease from Shafts, Bushing, Joints and More!

This tool is amazingly I used it to unclog somezerks fittings on a semi truck and it just worked so effortlessly. I had trouble greasing up a couple of spots I tried heating things up and even that didn't work I use a battery powered grease gun and it wouldn't push grease through a couple of whacks on this grease buster and it cleared things right up. This tool is such a life saver to reduce wear on your truck, equipment etc.

Helped free up grease fittings that refused to accept grease. Great tool

Read the instructions... This tool works! If you need to find a way to get grease through a fitting it's worth it to try this tool to save you a lot of time! Great tool!

I am a mobile heavy equipment mechanic. I have a few customers that don't know what a grease gun is or they run into a problem with a grease fitting and they just say screw it and it doesn't get grease until I come along. My remedy for freeing up clogged up grease fittings used to be to pull out the porta power and stuff the hydraulic oil to it. That process was kind of a pain due to the bulky size of dealing with the porta power. I had always meant to order one of these sets to try. I've had this since February. Used it quite a bit. I wore out 1 grease coupler and the company sent me a new set of couplers because I couldn't find them on their website. Very nicely built quality product. Very heavy duty and well made (I've beaten on these ALOT with a 5lb hammer) and they have stood up to my abuse. Worn out 1 grease coupler and a few o rings on the piston part. Nothing has bent or broken. Customer service with the manufacturer is AWESOME. Oh so nice to free up clogged fittings.

This is a great tool. It is not a miracle worker. It has worked pretty well on heavy equipment for me. Only time it didn't was due to the equipment joints freezing up. Like I said not a miracle worker. In my opinion don't let the others make you not buy this. It's well worth it.

I had some grease zirks on my military truck that were just packed with dried out and harden grease. Used this device and after several applications on each zirk I got them open.Would buy again!

I bought this to save some work on my skid loader. I maintain it religiously but I missed 2 grease fittings on 2 pivot pins. It was a learning curve. My first try was less than what I expected. I could not get the oil into the pin …. I was a bit disappointed. I thought about it before my second attempt. My first try I just tried forcing the oil in. I had cleaned the grease path before and tried just putting in grease. When attempting the oil nothing moved.My second try was a bit more thought out. I cleaned all the new ( and old ) grease and cleaned out the path with brake cleaner and a drill bit. I connected the tool and after 2 fills of Kroil I got oil out around the pin. Then used a grease gun and it worked excellent! I’d recommend this tool it really works as long as you get the grease channel cleaned out!

had a zerk that was impossible to grease. I ordered this. High Quality tool. I hammered with a 5 pound hammer. Had to get liquid PB blaster to put in it then it finally went in. As much as I hammered on this thing it should have ruined it, but it stood up. In the process I broke a coupler and I called the company and no problem they are sending me a new one. Now I am going to work on some really old farm equipment.
