Ford 971 Gas: Banjo Bolt

Hi-
Inframe rebuild ford 971, so I removed oil pan to access rod bearings.

Ive got a banjo bolt stirred in with other bolts. Sediment fuel bowl banjo in place, so not sure where else it would go. Power steering pump not missing one I can see and turned engine over and oil was moving into side mount screw filter. Nothing obvious on hydraulics. Nothing in parts diagrams points me in a good direction. Any ideas where that rascal came from..

Thank you-

Looks like a brake hose bolt. But then a picture can be deceiving about the size of it. But that doesn't help you much on a Ford tractor!

hat one looks homemade and not like factory fuel bolt.
 

Ok-good help. Does anyone know of a banjo bolt on this tractor other than on the sediment bowl?

If not, I guess it could be a home made bolt reused as a general fastener on this 60 year young machine I didn t notice when removing.biggest concern is something on oil pump is missing but having oil in new filter seems to cancel that concern.
 
There is a hard line that goes from the oil pressure gallery up to the rocker arm lube. I don't know about anything other than that. Not sure what both ends use to keep pressure in that oil line, but it's the only thing I could come up with.

Good info. I ve left valve cover off and have pre-oiled. When I change oil after running to temp, I can just drop pan and look over that area. Other than pick up tube, not sure if I pulled off anything else off to remove rod caps. Thanks to all.

That oil line is sealed to the inside of the gallery by EAA6594A seal. $2.94. Messick's has 4 in stock. the seal is a sort of hard rubber ferule.

ubber seal on both ends, I believe. Showcrop, there is the oil line being discussed here at one end of rocker shaft and another short line at the other end of shaft. Parts manual call both "inlet lines", but I'm a doubter. Is that short one just a shaft to top of cylinder head (open end ) dump of excess oil?

The two that I have been into have had only the long tube.

OK, just curious....see long tube on table that goes in at left and the short tube installed at other end.

I agree with NDIHC, that banjo bolt looks like the ones that hold the hose on an automotive disc brake. Most tractor style banjo bolts of that era had a hex large enough that the seat was slightly smaller than the hex, see 1st link example. The one you show has a flange head and sure enough you can find those for brake caliper applications, 2nd link. So either someone did some brake caliper swapping in your shop and let this one walk into your tractor bolt stash. Or someone previously put it in some location on your tractor using it as a regular fastener.

Nice photo-yes my pick up tubes are in. I appreciate the
good thoughts. Chalking it up to a bolt bin imposter!

ome hundred series Ford tractors used a similar bolt to attach banjo fitting to carb. Not all were the same, depending on model/carb.?

see how much cleaner the hole is? I'm sticking to homemade, myself.
