F700 hydrovac advice
 

Got a new hydrovac unit for my F700 from NAPA (thanks for the tip FTE ). It is not an exact replacement however. The old unit had a bracket welded to the front ( vac booster ) and a bolt threaded into the side of the piston housing on the other end. It was bolted on to the frame at an angle with the piston housing pointed up slightly. The new unit has three bolts in in the top of the piston housing and a plate on the vac booster to weld on a bracket. I made a bracket out of 3/16 thick angle iron. looks like this [_______ for the three bolts on top.
first thing, do I need to put the new unit in at the same angle as the old unit or can I mount it to the frame so its level.
second, will I need to weld a bracket to the vac booster portion of the unit or are the three bolts in the top of the piston housing sufficient to hold the unit in place. I appreciate any help u can give me:-X22

Boosters
 

Ill take the risk to say that I have a 2 Yd Trojan loader same booster
with just the three bolts. It is not level it came from Napa. On the other
hand I replaced the booster on a F700 that also came from Napa that
has the three bolts and one welded stud on the vac chamber near that
square plug for a small bracket and is kind of level or paralel with the
chassis. So I will say it doesnt matter. Trojan just stuck in where it
fits, it works, thats the way they made it. If the booster was on the
roof it will still do its job.
