180 Massey planetary housing drain plug.

[Hooked180]

I bought a drain plug for the planetary housing on my 1966 180 MF and I can get it to stop leaking.I bought the plug from a parts store and not MF.
Got ant ideas?

Did you have the old one to go by?

Is this a straight thread plug with a something for a seal under a hex head or is it a pipe plug?

I do not believe they are a tapered pipe thread. My 165 parts book shows a washer used with the plug. On my 65 they are a headed bolt with a washer.

There are both metric and non metric ORB fittings....
There are both ORB and FLAT washer type ORB fittings ......

"IF" you still have the original fitting......locate a NUT that properly threads onto the fitting....."IF" the fitting is a Straight thread....and yes, the thread on your new plug COULD be metric..

Where do you buy a tapered tread? Massey wants $22 for that plug and we aren't sure it is tapered.

Common pipe thread (NPT) is tapered and often has a square head.

Did you have the old plug to compare the new one to?

From the parts book it appears they may have used either a pipe plug or a straight plug with a sealing washer. Without a picture of the plug you took out in the beginning, it is just guessing.

Do you have the plug for the other side? Wow that’s pricey. I think Jim had your answer above.

Straight thread.

The plug I bought from MASSEY $21 new is a tapered. and I put pipe dressing tape and it still drips!!!!

The one that leaked I took out was a straight threaded with washer. I bought one from a parts store and still leaked. I bought on from Massey that the\e parts book called for and put pipe dressing tape and it leaks

I did that.

I am afraid to take the other side out I don't want it to start leaking too.

 

[Jim.ME]

I did that.

How did you compare them?

Did you measure the outside of both threads with calipers?

Did you put the threads of one plug into the other and see if they lay tight together?

What is under the hex head for a seal?

Is the plug going straight in or is the head cocked (gap under part of the head when part is tight to the housing?

If the original was leaking it is possible someone screwed the hole up, Have you cleaned the hole and checked the threads in it?

We can't see what you are dealing with. We have to ask questions and need full answers.
