Case 580c

[Bryan5238]

Think I’m gonna see a dealer see if they make a tach drive that will work

 

[Tinkerer]

Good Luck !

Nice price and a bargain at that. Would Dale at e-backhoeparts.com have that?

 

[Bryan5238]

It needs to be male threads. That Will fit the 188 but adapt to the 580c tach drive

 

[Tinkerer]

What about getting a 188 tach drive and changing the tachometer to one that matches it ?

 

[Bryan5238]

Well I thought about that but it looks like the tach on the gauge cluster is built in. If. I cant find one I’m gonna just plug the hole.

Here is a picture of it

That is probably your best option.
You could put a digital tachometer on it. They are very inexpensive.

Next head scratcher at least for me. I’m trying to start the motor before I put it all back together. I was going to use the 188 injection pump but it crapped out on me. It runs at 1900 rpm I’m gonna order parts and rebuild it but. I decided to go with the 207 injection pump that is like new runs at 2100 rpm . I set it at 8 degrees btdc. Is that correct with this pump? It’s acting like it’s wanting to fire but I figured it should of kicked off by now.

 

[Bryan5238]

Never mind it started

 

[thepumpguysc]

Lol.. u can get all the rpm’s u wanted with the 188 pump..
Simply back out on the hi speed stop screw.. BUT DONT DO IT W/O A KNOWN GOOD TACHOMETER..

 

[thepumpguysc]

The problem w swapping pumps is, they are built w a certain transmission in mind..
Shuttle shift.. etc..

 

[Bryan5238]

I’m not. I’m gonna seal that hole. I don’t run my equipment with a tach anyways least most of the time I don’t use one. Usually by ear and never full rpm’s.

 

[Bryan5238]

Aww I gotcha. Well I’m that case I have the correct pump on there.

 

[Bryan5238]

Well why I have you guys on here. Is the tachs for the 188 and the 207 the same diameter? The guy from Shaifer salvage said he might of given me a 336 tach?

 

[Tinkerer]

A 207 tach-drive should be 1.063 OD with a 9 tooth gear.
The person at Schaefer Salvage that sent you that 336 drive should be able to help you.
Hagan Tractor Parts has this one.

 

[Bryan5238]

Yeah he is looking

 

[Coy Lancaster]

Remember the 207 injection pump times at TDC 0 degrees

 

[Bryan5238]

Just mic the tach that I have it looks identical to the picture but it is way bigger that that diameter. The hole in the block is also 1.06 inches

 

[Bryan5238]

Well was working on the brake system today. Both master and slave cylinders are froze up. Took them both apart. Was curious how easy they are to rebuild? Versus buying new. Gonna need to replace the left hand side seal. It wasn’t leaking but the seal is all messed up. The right hand side was leaking. Are there 2 seals I should replace in there one big one and one small one that goes on the inside shaft?
