Looking to lube a Gemmer manual steering box with the proper grease. I have read the threads on this and am a little confused. If I use XG1C or C3AZ-19578-A ...how do I get the grease gun to pump the grease into the fill hole on the top of the unit?. Do I remove the quick connect fitting on a grease gun( somehow or snap in a new fitting into the gun) )and just squeeze in grease til it over flows?. I have also read where GL 4 hypoid was recommended in my steering box. Please clarify for me?

 

i'm looking for same info

 

Not sure if it matters..but my truck is a 1965 f250 4x4..

 

mine is a 64'
also was wondering what lube to use in t98 tranny
heard that not to use gl5 additive in the lube?
just overhauled mine

 

The Gemmer takes Hypoid Gear Lubricant. AKA 90 weight gear oil same as your front and rear axle.

C2AZ-19580-A above -25 degrees
C2AZ-19580-B below -25 degrees.

 

The T98 takes SAE 50 weight engine oil above 10 degrees, and SAE 30 engine oil below 10 degrees.

Thanks Garbzz!!.. I have a manual 4 seed tranny... in my 1965 f250 4x4...would that be a T98?

 

good info thanks

 

Any idea where to get straight 50wt, I haven't been able to find any in years.

 

You should have an NP435 unless its been changed out. Have you looked at how your shifter is held into the trans. If you have a cap where the shifter goes into the trans that unscrews its a T98 if you have to push down on a spring to release the shifter its an NP. Your shift pattern on the NP for reverse is over to passanger side and back if towards the dash it is an T98.

 

Is the Np435 the same oil set up...takes SAE 50 weight engine oil above 10 degrees, and SAE 30 engine oil below 10 degrees?

 

I have a NP435 in my 66 and thats what it calls for.
