Here is an update.....
Well....since the weather is finally improving somewhat, (sunny but a high of only 29 degrees yesterday!)
I was able to fabricate the mounting brackets for the twin booster reservoirs, and then mount them behind the modified battery box. These two reservoirs where needed back when the truck had the Caterpillar 7155 16-speed transmission, that has a really big "appetite" for AIR!!!
I thought about leaving them off, since that would make the air charge up faster on start up. This is especially true, after the truck has been sitting for a while and all the air has bleed off. On the other hand, I do like the safety of the extra two reservoirs, so I decided to keep them.
I modified the bottom of the battery box to accomodate six Optima "Yellow Top" batteries. This consisted of welding a frame of 2"x1/4" flat stock, on edge, on to the bottom plate. This shoud keep the batteries firmly in place on bumpy cross country trips. All that I have left to do on this, is fabricate two hold-down brackets and get the cables made up for the two extra batteries.
Today, I welded up the front support frame for the engine compartment hood. For it's constuction, I used heavy duty 2"x4"x1/4" rectangular tubing because it also doubles as a ROPS and the attachment point for the two front fender mounts.
I was going to take the cab off today, but it was apparently to cold and despite extensive begging, pleading, the excessive use of starting fluid and then finally cursing, the "trusty" 10 ton (crane) could not be conviced to come to life....
