1961 MF 65 Diesel Tachometer

I've asked about this in a different YT forum. I still have questions and hoped there might be more people here with knowledge about Massey Ferguson. Last week I bought a 1961 MF65 diesel. I've worked through several issues, but haven't found information about the tachometer drive. The tach doesn't work and the cable isn't turning, but it looks good. Turning the input end manually will deflect the tach needle. I'd like to find a source for parts and get a better understanding of how it works, before disassembling the system. I found this video https://www.youtube.com/watch?v=XcXJ12GEMa4 about a glue repair on a tach drive adapter from an MF35.
The system is clearly very similar to my MF65, but not identical and I wouldn't disassemble my tach drive to do a glue repair, either.
Any information applicable to repairing the MF65 tach drive would be appreciated.

https://www.youtube.com/watch?v=XcXJ12GEMa4 At 0:55 in the video and below the top steering wheel spoke is a bulbous chrome stem. Could someone please identify this. Mine has a wire coming out at the bottom that isn't connected.
 
Thanks for identifying the dash light.
Are you saying one of the 2 Perkins engines you have specified fits my MF65 and the other one fits the MF30 in the video?
Could you tell me which is which?
I can see the 2 engines are different. For example, my engine has 4 bolts in the rear camshaft cover and the one in the video has 3.
I can see that the tachometer drive is off the back of the camshaft on both.
I see a tachometer drive adapter and partial disassembly for an MF30 in the video
But I haven't seen images of a tachometer drive system positively identified as fitting the Perkins engine in my tractor.
Could you refer me to such information, please or tell me where I could get one?

A diesel 65 will have a tachometer drive as noted. It will look like a speedometer cable attached to the rear of the engine. Get a new tachometer and a new cable.
 
I've been looking on ebay for a tach that fits the Perkins 4.203, but can only find tachs for the gas engines. If you have any luck finding one, could you post where you found it? Thanks!
