Just a few questions from new england...Does anyone know what the gears ratios might be on this truck? I have the 4 speed manuel. Plus reverse, anyone know what the reverse gear might be?Anyone know how much power the power steering pump puts out? I want to power a hydraulic pump thats rated at 2000psi at 12gal per minute. Thanks for any help.
i don't know about the transmission gear ratios... as there might be more than one transmission.. either a NP435 or an NP445 could have come in that truck... the NP435 has a granny low gear... the NP445 DOES NOT have a granny low gear..i think.. but i am NOT sure.. that the NP435 has a SINGLE PTO cover.. and the NP445 has a one on either side.... ah.. more infoNP4500 (H) 4.56/2.28/1.31/1.00/5.65 Chrysler '70-79 (all synchro)(also called NP445) "Oh, there are a few variations and derivitives.

NOT A CHANCE..that truck has a saginaw P pump.. probably 3 gallons a minute at 1200 to 1300 PSI MAX... with the belt squealing.. what you will want to find it the Hydraulic pump with the electric clutch thats used on TOW trucks to power their hydraulic systems.. http://www.northerntool.com/shop/tools/product_200329778_200329778you might be lucky enough to be able to mount it where the air conditioning compressor is. using the same belt alignment..oh... and since you have either one of those transmissions...why not search the junk yards.. or call someplace like PTO sales.. for a PTO driven hydraulic pump..
