I have looked high and low though the JD catalog for the 1640 Mannheim. I can't find the pressure switch that operates the "low transmission oil pressure" lamp on the dash.
Anybody else able to find this well hidden pressure switch.
No apparent loss of effect on the loader's high hydraulics. The plan is to test pressure at the port and test the pressure switch on the bench to verify accuracy.

One of the joys of the Mannheim works and the terminology/translation of parts. Look in the same catalog for a load control shaft.....it isn't there. Look for "Parts for load control" and your luck will be better. It was irritating when the same component was called different names in the Tech manual and the parts catalog
 
Thanks txjim . I had looked at the covers used for the
independent pto without the high/low and just could not get my
eye on the PS to find the part number.
I looked in the parts book later in the last half of 40 series production that was all Mannheim. The numbers showed up together with the images there.

You're welcome. I agree with Tech 7 parts are more difficult for me to look up in the parts cat. for the built for European tractors than for built for N America. On difficult to locate parts I look in built for N. America to find part number crossed over to European tractors.
 
Sometimes technical part names translate very differently in different languages. I worked with some German drawings and found that a "sheet metal gap filler" was their name for a "shim".
 
The same can be said for John Deere self propelled forage Harvesters built in Germany
I worked on several at the dealership in Ontario Canada, and the Germans had different terminology for a lot of parts on those machines - was tough going to find the correct parts picture.
