65 Patrol Rebuild Starts Here

[Esteban]

David, front and rear differentials are exactly the same, so in your case, just the change the welded differential case.

Thank you Esteban and everyone,

I have decided to run it for a year with OEM gears because so many real Patrollers are happy with the original set up, plus we have the winch. If after a year we feel we need to lock the front differential we will, no big deal..but I'm betting we never do it.

Here is what I've learned this week.

a). The locking axle nuts are unique to the side of the vehicle. They are generally pretty beat up after 55 years. The driver's side are left hand threaded and the passenger's side are right hand threaded. No, I don't know if the hand determination is facing the front bumper or with your back to the front bumper. We ended up with my original worn out left hand nut (if my mechanics determination of left or right hand was accurately conveyed through the front desk then that solves the mystery....but in my business we have always struggled with left and right handed designations so I never count on an accurate determination until they tell me and show me) and three extra right hand threaded nuts.....which is this example/case are correct for the passenger's side. However, Flaggoni (I think) linked us to the $8ish nuts on eBay...we are waiting now for delivery. Big thanks!

b). The 63 water pump I took off the Green Machine was replaced with a rebuilt water pump I bought from RMP & O from a 67. Will at Kellogg Water Pumps was interested to know about my 63, which he rebuilt last week. He says that somewhere around 66 they changed from a brass impeller to a cast iron impeller. So now I have a freshly rebuilt water pump on the shelf with a brass impeller...which is kinda cool and Will thought so too.

c). Wheel/hub bearing shims, I suppose that is what they are called, are hard to find.Thanks Ron.

Waiting to Patrol,

Greetings,

Presidio Patrol finally got out of Hill Country Auto yesterday. It only took 2 months to get the rear axle rebuilt in their worthy hands. Feeling confident that I finally had a "solid" Patrol I took it for a late afternoon drive. Well, I made it about 3 miles. Recall Eddy the Eagle rebuilt the Rochester carb, which was the third complete rebuild for that carb since purchasing it "as new" from a specialty rebuilder in Oregon, BEFORE Hill Country's freshly rebuilt axle failed within 3 miles of their shop.

During the 8 mile drive from my warehouse to my house, which is flat, a smell of fuel drifted through the open cab. It ran smooth. I was feeling good. A gasoline smell was present during the evening drive but by now I'm thinking that is just what a 50 year old motor smells like. No big puffs of oily smoke from the tailpipe.

On the return to my house it stalled and sputtered to a stop climbing the hill to my house. I eventually got it restarted by choking it and then rolling uphill by shifting into 4 low to keep the compression high then slipping the clutch at high RPMs to limp it up the final 100' feet of the hill. The chase car said sparks we shooting from the tailpipe. It died again after 300' but at least on the top of the hill. No restart possible. We pushed it until it was off the parkway.

However....after it sat for a couple of hours and was cold it started perfectly and ran smooth. I drove it to my house the remaining 100'. The temp gauge never showed hot nor did it feel hot with the hood raised. It ran smooth 100% of the time until it abruptly started coughing on the neighborhood hill.

Eddy has installed extra large fuel filters in both Patrols. It was sitting at 1/4 of a tank of fuel when it stalled on the hill. It has a new mechanical OEM type fuel pump with Rob Moore electronic starter upgrade.

Thoughts?

PS - Presidio Patrol has a staging brake. It sets the brake with a flip of a toggle. Basically a second emergency brake. It came in very handy on that hill. That is a good idea if you live around hills.

Greetings once again,

After three rebuilds we are likely going in a different direction than the Rochester Carb I bought rebuilt from that shop up in Oregon. Unless someone has a good idea. We are stumped.

Status Report
After no more than 10 miles of light driving this Patrol completely fouled all the plugs and unleashed some amount of fuel into the oil...which was the exact same problem two rebuilds ago. The carb has been rebuilt four times including the time it was rebuilt and then sold to me. The motor and transmission seals have been replaced between carb rebuild 3 and 4.

The fuel pump is new and it was pulled and pressure tested again today, no leaks. Eddy the Eagle says he only knows of two ways fuel can get into the oil; carb and fuel pump. Is there a third? The cylinders have been pressure tested three times in the last 50 miles, all good at 145 psi, one was at 125 psi. It goes without saying, it starts fine, runs smooth but runs really rich.

Ideas?

Patrolling for new Plugs,

David, sorry to hear about yhis problem. The good thing is that your mechanic seems to be in the right track. I once had a big leak from the fuel pump into the crankcase, but that didn't cause any ignition problems.

It looks as the carb is letting all that fuel go inside, flooding the engine. Probably the needle and/or float are not working properly. Easy said than done after all the attempts at fixing this carb that you have endured.

Thanks Esteban, Eddy says he will not stop till it is fixed.
