Hi everyone, I took out my Yong heng and dusted it off to flll my tanks today after a couple months. I never had a problem with it before, but when I tried to put in new oil, the oil cap twisted and broke completely off. In the pic below, the entire threaded part is still stuck in the Yong heng and the "handle" part broke off at the base. The sides of the threading looks like its fused/stuck in there. 

Any ideas on how to get that threaded part out? There's nothing on the back to grab...

Pizzaman,

Lawn irrigation tool for removing broken plastic threads from inside PVC piping might also work. It's a T-handle with a metal, tapered multi-tooth end, which, when inserted in plastic threads, grips to allow twist out. Standard size might be too large, I'd get the smallest size available. Inexpensive and common at any home improvement store. Also, check eBay for replacement oil breather for Yong Heng. Proper oil breather is essential.

Pizzaman,

The irrigation tool mentioned is called a coring tool or plastic nipple extractor, has two interchangeable heads (1/2" and 3/4") and costs $4.87 at Home Depot. If the plastic threads are fused/stuck, as you say, and nothing else seems to work, I'd try this. Heavy is correct on replacement oil breather tubes, I couldn't find on eBay, but Amazon has listed under, "Yong Heng Parts." Best of Luck,

WM

Here's a link

Amazon.com : plastic nipple extractor

Also, FWIW

When mine broke off I used a large pair of needle nose pliers,

I put the nose into the fitting and pulled the pliers open using both hands

Then rotated the fitting out of the compressor

brahahahahahaha.... allow me the luxury of ROFLMAO - before you guys go ape on me calling me an ass, let me state that this happened to me a while back. I know the feeling.

When the oil cap snapped off, it felt like I snapped off my baby's dick off its base, severing it from its balls... the horror. :) 

Here's what I did. I used a pair of needle nose pliers, inserted it into the base to remove the plug by screwing it out. Ordering a new cap is going to be a 3-4 week wait from China. So in the meantime, I re-attached the broken appendage back to its base surgically using screws. It only has to be strong enough for you to screw it back temporarily after an oil change. Wrap a small towel around the re-attached appendage and opening. As long as excess oil/pressure can still escape, you should be good to go. The towel will have a little oil deposit after use, but at least it allowed me to keep using the pump till the new cap arrived.

Hahah yea it sucks! But, bound to happen at some point I guess. I still haven't had a chance to get to the hardware store today. I'll try the needle nose pliers before going to the store to see if that does the trick. 

Worriedman -- thanks for the tip. I didn't know you could just buy the front part and am tempted to. l give this a shot first, but good to know I have a backup option.

Pizza,

You're welcome. Just search "Yong Heng Parts," on eBay, I think front and back cover are sold together, but only around $30. I'd use any silicone automotive gasket sealer to mount, tightening bolts in increments and in "X" pattern.

The front cove doesn't use any sealer. It comes with a rubber separator plate that acts as a gasket. There's a hole in the rubber sheet right behind the sight glass for oil to pass through so if you ever want to clean the sump you have to remove the front cover because an oil change won't get it.

Heavy,

Thanks for good info. I remember seeing a picture of a Yong Heng with big gobs of white goop around front cover so thought they used that for sealing. You know, come to think of it, your picture is what I saw flipping thru eBay Yong Heng parts. and thought it was a front and back cover for sale together. Well, at least, between the two of us, we got the accurate front cover availability news to Pizzaman. Hope he solves the problem without new cover, but now he knows he has the option. Thanks again, WM
