720 Part # Thread

[ElliotV]

Does anyone know where I can get a properly sized upper radiator hose for a 85 4x4. Mine is 38mm and any that I find are 32mm. When I installed my inline temp gauge to keep a eye on coolant temps I originally ordered a 32 and it didn't work and a 38mm did. Everywhere I look has the same part numbers for a 32mm or 33mm hose.

That's 1  1 /4" and 1  1/2"

Yes that's just what the ones I found listed were metric and the adapter I ordered was standard

Yep wrong diameter hose.

Tight pushing it over the beading but wet it and give a good push.

Maybe if I end up pulling the thermostat again I can give it a try but I think I finally got it to stop leaking after replacing the gasket. Hose doesn't have any tears and I replaced the clamp with one that won't cut into it like the oe Nissan ones.

Does anyone know what park brake cables will fit a 720 dually (cab a chassis on paper) camper? Rockauto lists some for short bed and long bed, but also notes that its single rear wheel. 
 

My truck is an 85 dually with full floating rear end. The park brake has been sticking lately, and with drums also being pretty much unavailable I’d like not ruin them.

All Cab/Chassis trucks were made from 2wd long wheelbase frames like the King Cab and Long Box. However being a totally different differential the the HD or Cab/Chassis cables have different part numbers. 

 

RH 36530-10W70

LH 36531-10W71

 

I've found that constant use of the hand brake keeps them free of rust and sticking. Keeping them properly adjusted is also a good idea.

Thanks. They appear to be discontinued by Nissan, and little to no aftermarket support. I think I will try and get some lubricant down inside the cables and pull the wheels to make sure everything is good in the drums. 
 

Not able to use it regularly where it’s a camper that is parked 8 months a year.

The proper lubricant is not WD-40, but a low-friction lithium grease. You can use WD-40 to get it unstuck, but then follow up by re-lubing the cable and the pivot points. They sell special cable spray lube at the auto parts stores
