Finally getting to reassembling '74 JH from extended engine rebuild(20 years) and cannot determine how to re-attach cast fitting that connects the lower radiator hose to the water pump. There is a threaded bolt hole on the side of the head but I cannot find the bolt that attaches here nor the correct size & thread. Also, is there a bushing or spacer that sits between the head and the tab the bolt passes through on the cast fitting ? The clearance between the cast fitting and the cam pulley is really small so I know I need to get this secured properly. Attachment: Water Pump Inlet Line.jpg (Downloaded 124 times)

It's a stud. If I recall it's an M8-1.25. Hose fitting slides directly on stud and secured with flat washer and lock nut. Should show in parts manual.

Slide the pipe onto the stud and look at the alighnment between the water pump and this pipe without any rubber hose in the way. I placed a washer or two between the block and the tab on the pipe to get the two to be in alignment with eath other. Then I used perhaps only a 1-1/2" long piece of radiator hose to join them once I had the shimming figured out. This keeps the flow path nice and stright and helps to get this pipe to clear the cam pulley. Also these castings are rubbish so take a file and knock down any flash or mismatched ridges that exist were the hose pipe is drawn down onto the casting by the hose clamp. It seems most of these castings were poured with a fair amount of missalignment when the molds were joined and poured. AP

Jim : Thanks for the feedback. I have looked in the parts manual and can't seem to find the stud/bolt info. atg : This is very helpful. I recognize getting this right is important and had no photos or drawings for reference. I may be trying to use too much hose length as well as it has been a bear to get everything aligned properly.
