The Chaseside drawing did not do the Dumper any favours, looks like catastrophic final axle failure!
In the OP's photo showing the engine with the missing injector pump there looks to be another pump (or something) with a drive coupling similar to that the missing fuel pump would have had. I wonder if the injector pump would have had a mod at the Bell housing end to drive an ancillary. AFAIK the Chaseside of that era was gravity tip so I wonder what the pump was for? Did it have vacuum assist on the brakes?
Haha! OK, it's probably the case, can't imagine the chain drives working well in muddy conditions either, very exposed.
You're right, the tipping is gravity and that additional pump is for the servo-assisted brakes. I'm asuming that the pump and master cylinder would have all been Ford parts.
And thanks for the serial number website link
