I discovered the 5531 has an under of 2:1,direct is 1:1,and over of 0.72:1. Also,the Clark 5 speed,IF it turns out to be an overdrive,is 0.80:1. With the axle in high,I have 6.40:1. With 38 inch tall tires,that gives me about 80 mph @ 2600 rpm. If the trans. isn't overdrive,it'll be about 65 mph. Going to a tire 40 inches tall,without OD,I show 67 mph,and with OD,84 mph.assuming enough power and nerve,of course...I suspect this truck may be OVER-overdriven.(More gearing than I could find the horsepower to ever use.)
OR
Putting it in other terms,70 mph with 40's,double over,etc. would be 2170 rpm's. If it's a direct 5th trans. I'd have 2700 rpms.
I guess my next logical move is setting myself to getting a title for it,so I can go learn how to drive it.
Got the lights working right,except the low beams on the headlights. That may require a new dimmer switch. I have brakes,but the HydraVac isn't doing anything. No vacuum leaks,so,to my way of thinking,it has to be something plugged in the hydraulic side.(or maybe it's just full of rust...)
I still have no charging system,and am guessing the brushes are bad or stuck in the generator. I guess I'll try a rebuild on the generator,and hope the regulator is okay.
Well,onward we go
