Case 580c

Okay thanks

You guys happen to know the thread size on the 207 tach drive? It’s male threads. Think I’m going to have to use it.

 

[Tinkerer]

Think I’m going to have to use it.

If you are going to use it, you need a 207 tachometer cable for a correct fit.
I don't know the thread pitch. NF will be very close.
Any machine shop could measure it.
Why do you need to the the tread pitch ?

 

[Bryan5238]

Well I removed the old 188 tach because it was female thread and it wouldn’t work in the The 580c. I was going to find and I am still looking for a tach drive from a 207 so I can install it in the 188. If I can’t find one I am going to have to make a puller to remove the drive from the 207 that I have to use it in the 188 so it will connect to the 580c. But I finally found the thread size in the manual this morning. A new tach drive is over thousand dollars. They are proud of them.

 

[Tinkerer]

What is the thread size ?
What manual did you find the size. Others reading this thread in the future would benefit from that info.
There is a used one here--->http://hagantractorparts.com/engineparts.htm

 

[Bryan5238]

The size for mine is 7/8”-18
It’s the bushing that screws onto the top of the tach. The 188d is the bolt looking one that is 3/4” there are 2 different types

 

[Bryan5238]

Might get lucky. Think Shaifer salvage might have one a whole lot cheaper.

 

[Tinkerer]

Take your time and do some searching. Especially in ag equipment salvage yards.
I only post Hagan's as an example.

 

[Bryan5238]

Shaifer salvage had one he is going to send me! Was cheap too. I’m glad I didn’t want to build a puller.

Guys my instrument cluster glass is faded to the point you can’t read any of the gauges. Is there anything I can do? Could I remove the plastic glass and replace it with new?

 

[Bryan5238]

Another question. I’m looking at my wiring diagrams. Gonna have to rewire a lot of it. Wires are bad shape with years of splicing and all sorts going on. There is a wire that goes to a bucket spool detent? What is that?

 

[Tinkerer]

It is for the return to dig function.

 

[Bryan5238]

Does it need to be energized? Or will it work without it?

I tried headlight restorer on mine and it actually cleared it up a little.

 

[Bryan5238]

Okay thanks. I’m gonna take the cluster out and see if I can clear it up. Or if I can remove the glass somehow.

 

[thepumpguysc]

I too have heard of the headlight restorer “trick”..

Apparently brake fluid & a soft cloth works well Personally I would try the fine W&D paper & Brasso / Metal polish.... Look Here

 

[Bryan5238]

Dang I think I’m going to try the brasso chrome polish. That looks like new!

 

[Bryan5238]

Well guys I picked up a 207 tach drive but apparently the 188 block has a smaller diameter hole because this tach will not fit the hole on the 188. Any suggestions? wondering if I can turn down the 207 tach to fit? Or possibly drill the hole out idk.

 

[Tinkerer]

Don't drill the block.
Get the correct drive.
Getting the wrong one to fit in the hole doesn't mean it will mate up with the camshaft gear correctly, if at all.
