The box is under the passenger floorboard and is more an arrangement of heavy steel flatbars than an actual box. There is an access panel in the floorboard but it's just barely large enough to access the cell caps; nowhere near big enough to lift the battery out through.
A few of the flatbars comprising the battery box have carriage bolts but only on one end. For that matter all but one carriage bolt have their heads inside against the battery so I can get the nuts off but I can't get the bolts out.
How, exactly, is one supposed to get the battery out of this thing? I'm sure it's something simple I'm overlooking but I'd better figure it out before it's time to replace.
Thanks

At least I know what I'm up against.
Thanks

My method to work around the issue was to get a high quality battery so hopefully I won't have to "experience the joy" of taking the floor apart but once every 7 years or so. That's the plan anyway. | | | | | Joined: Oct 2012 Posts: 182 'Bolter | | 'Bolter Joined: Oct 2012 Posts: 182 | Yeah, it was not the best design. I thought the military trucks had the battery mounted behing the running board. Is yours too early for that? | | | | | Joined: Nov 2011 Posts: 1,611 'Bolter | | 'Bolter Joined: Nov 2011 Posts: 1,611 | The early production 1940-march 1942 YP and ZP military trucks had the battery under the floor the same as civilian. I think the change occurred when they went from 25 amp positive ground to 40 amp negative ground. At least that is what the parts manuals indicate. | | | | | Joined: Apr 2005 Posts: 926 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 926 | I saw one a while back that was under the floor,and the guy used the front cover for a breaker box to cover the hole. I'd thought about doing that trick when I changed to a dual reservoir master cylinder,but I was too cheap to buy a box just for the cover. It DOES work well,and looks pretty nice though.
