- Innovative Products of America (7862) Grease Joint Rejuvenator Kit Professional Model for Flushing Out Hardened Grease from Shafts, Bushings, Joints and More

This tool worked very well to open up a couple of grease zerts on my tractor. Easy to use. Nice case to store the tool.

I ordered this item figuring if it didn't work I could return it. First I read the reviews on the item, and they were very helpful. We had a mini excavator in our fleet that had a pin the would not take grease no matter what we did. I had people remove the zerk and replace. they tried drilling. They tried heating it hoping it would loosen up the stuck grease. So I bought this as a last resort figuring if it didn't work, I would return it. First I read the instructions and used Marvel Mystery oil. They said penetrating, But had lots of marvel mystery oil in the truck as we use it for about for about everything. I took a few minutes to really figure it out, as to bleed the air out of it. Seems like once I bled the air, I had about a half cylinder to work with. I grabbed my 2 pound hammer, and started tapping. It was leaking at some fittings as I had not tightened them enough when I screwed the base on. Back to work. I started tapping. It was messy as the pressure is very high when you tap, and if the zerk is plugged, it has to go somewhere, so it seeped and threw a little oil out of the plunger. Now I had read where people said it took fifteen minutes or a little longer on a really bad fitting. After about 10 minutes or so, I could see a little bit of seepage of oil coming out of the bushing. I kept at it for about another 5 minutes. Noticed it looked lie a little more oil seeping out of the fitting. It was noticeably easier to tap on the plunger. So I grabbed my pneumatic grease gun, thinking I would still need more work, but hoping for the best. I was absolutely surprised when I seen grease come out of the pin ( bushing). I think the people who give this poor reviews need it can be messy, as the excess pressure needs to go somewhere. Second, keep at it. The pin I did had been froze for a year. I would say on a bad pin 15 to 20 minutes is not unusual. On stuck or plugged king pins, only takes one or two times as we grease regularly. Same with u joints. 5 stars from us, and especially all of the people who tried to free it.

I’m not normally a review writer but I do rely on them for my buying decisions. So in this case, I didn’t hold high hopes for this working for me after reading the negative reviews. I have had a driveway gate hinge that has never accepted grease since installed 8 years ago, I just ignored it. I recently decided I needed to get grease into it before it seized up. After seeing a YouTube video where a similar tool was used to get grease into a fitting, I found this one. I used 3-in-1 oil in the tool and gently tapped the oil into the fitting with a regular hammer. I took my time and slowly tapped in the entire cylinder of oil I had loaded into the tool, even though the oil started seeping out the top of the hinge after about half of the oil had been forced into the fitting. I did have to back off the knurled nut to get the tool off of the grease fitting, as described in the instructions. Attached my grease gun and forced the oil, followed by grease through the hinge. Perfect!

I tried it but it could not do the job, but I have only tried it on one job

WOW!!!! Took a chance. Tired of replacing zerks. This thing blows them out fast! Even on an excavator where hands dont or wont look for a grease zerk and they go unused for a couple weeks, this thing blows them clear quick. I use hydraulic oil mostly. Solid stainless construction. Comes with short whip for hard to reach places and packaging is strong and reuseable. A solid 10 / 10!

I bought this tool to free up some plugged up grease fittings on my backhoe and at first it didn't work because I was using PB Blaster and WD40 and the plunger was bouncing back after hitting it. The key to make this tool work is to fill it with ATF fluid/transmission fluid and to use heat if you can on the joint/fitting. It freeded up some old grease on my old backhoe and saved me a lot of money in repairs.

A tool that keeps on giving. If you work with grease points on machines, you will need this in your toolbox. I was able to successfully bust open numerous clogged fittings on our semi trucks. Saves time and money paying someone else to do it, or a mechanic who just wants to part swap the problem away.

I had never heard of this tool before. I was overwhelmed by the various manufacturers choices available. I am cheap, but I only like to “buy onve, cry once” and found cheap knock offs most often result in multiple disappointing purchases. My research paid off and I made the correct decision to pay a little more for the best. My tool came in a quality case with attachments and spare coupler. QUALITY product backed up by OUTSTANDING customer service. I made technical support phone calls on two occasions and my phones calls were promptly, professionally returned by “Paul”. I cannot recommend this product enough.. the fitting rejuvenator got my 23 year old bushing taking grease again after a little perseverance and save me a very large mechanic bill! My advice would be to buy the best the first time.
