Relay

[clayson]

Trying to find a replacement relay for tractor( it’s for the combined hydraulic pump on case 844) but can’t find anything to match, anyone know if I can buy just a standard relay to fit? It’s a 5 pin one with resisters and what not.

Are you sure it is the relay? I don't know how skilled you are but I recently had a similar problem (MF 390) which turned out to be a bad connection elsewhere. I assumed it was the relay as it didn't click. I now know that the electronic ones don't click!

To confuse matters further, my relay had 7 pins, but two turned out to be locating pins with no other function, so effectively a 5 pin relay.

When I realised that, I did try a 5 pin relay of similar rating. Most functions worked (but not one) and nothing got destroyed. Finally, put back the old relay and repaired the poor connection and everything is now working.

There's a fair bit on the internet about testing relays if you Google. This diagram of a typical 5 pin relay might help:

Don't think a standard relay will do, as you have terminal 85B that won't be on the standard relay. Its possibly just a second earth for the coil (like terminal 85) but cant be sure.

Thanks that diagram will come in very handy! I’m not positive it could be a bad connection somewhere, I’ve just thot it was the relay cuz I’ve had to give it a tap now and again to get it to click in but recently no matter how many taps I try it won’t wotk so I’ve had to make the connection on the relay (where normally the coil pulls that hinged piece of metal over to make the connection on the contacts making the normal click sound) by inserting small piece of plastic. Thanks for the info chaps I’ll take another look to make sure there’s no loose connections anywhere

Parts catalogue just describes it as a relay.
1328844C1 has been superseded by 1534530C1 but a part number search doesn't show it being used on anything newer than the 844 and 8/9/1056. I'd try your Case dealer, if it was a standard relay I'd say it would've been used on something newer.

Thanks boohoo If i can’t find any loose connections I’ll try dealer

Looking at my parts book here and the relay also appears on the page "auxiliary valve reed switch". Looks like there's a U shaped switch of some sort under the spool valve levers that is connected to that relay.

@clayson did you find a relay for your 844? There's someone in one of the IH Facebook groups asking where to get one.

 

[clayson]

No I never did find one, but I managed to revive the existing relay after, been fine ever since.
Sorry I can’t be no help. Good luck to them hope they find one

That relay is with the delay timer.
You should be able to put any 5 pin automotive relay instead but you will loose the delay function.
If you still will struggle exact replacement i can fix it for you.
