Barry:
I need more vocabulary lessons:
To me a Taco is a Mexican-style food you eat. I don't know what it means relative to our motorcycles.

Are you referring to the speedometer cable coming out of the transmission housing?
Or does your CJ have an actual Tachometer, unlike my Urals?
Lots of learning/teaching opportunities with our rigs...

On the M5 series the oil pump drove a Tacho.  When the SV or OHV engines were used in plunger frames the tacho was replaced by the four pin style of pump cover. It can be replaced with the Ural style oil pump cover used on other 12V CJ/XJ models. A spacer will be needed but most people just use a large nut. To remove the cover, make up a pin spanner or just use a drift to turn the cover. To repair the leak, thoroughly degrease and fill the hole with two-part epoxy.

For me .. Memories came flooding back to an Early CT Machine.. We had a segment of Schooling that everyone looked forward to.
Racko Tacko and Pipco Tipco,   Actually rack0 tack0 stood for Receive acknowledge  "active Low" [0] and Transmit acknowledge "active low" [0]... an interrupt system on the Mainframe Computer... ripco and tipco were receive input command 0 and transmit input command 0 for DMA Transfers....

Very Long Time ago... Thank you for Jogging my Memory... Now... Back to Boxers!!!!

According to PW's post above:
Yes. The cover is threaded and should unscrew.

What is commonly referred to as a Chang Jiang is normally a plunger framed bike with a horizontally opposed  (boxer) engine. However there were two main manufacturers and multiple small manufacturers and there are many variations in components for the engine, gearbox and frame. The OHV engine and 12V SV were developed for a frame loosely copied from a /6 BMW. Again there were multiple manufacturers. Because of the subtle variations it would be best to show a photo of what you are talking about in future.
