[Stripped hub, second one!l]

I stripped a hun on my 1985 BRAT, for the second time!   The 36mm castellated nut was at the right torque, with cotter pin.   What am I doing  wrong?

[Doing the Gen2 alternator upgrade, need v pulley, what should I do?]

1985 BRAT.   I have decided to upgrade my alternator to a 90amp 1989 Nissan Maxima model.  

Is there an online source for a v pulley?

Is it possible to use the pulley from the original BRAT alternator on the new alternator?

[85 BRAT, where is AC thermostat? Wiring Diagram pic]

The schematic can mislead you but the circled thermostat is actually in-circuit at all blower speed selections. ...

 

With the battery disconnected, I tested the resistance from the AC relay, through the thermostat and fan speed switch, to ground.

 

You're right!   The thermostat is part of the circuit in the four fan speed positions.

Thank you for the response!

I am trying to make the air conditioner work.

I have  1984 Subaru 1600 1800 Engine and Body Service Manual

and 

1984 Subaru Wiring Diagram and Troubleshooting 

 

It looks like the 85 BRAT has the same dash and engine wiring as the 84 4wd wagon.

 

 

 

 

 

 

[Is 1985 BRAT wiring the same is 1984 GL Wagon?]

I have the manual to the 84 gl, but the vehicle I drive is an 85 BRAT.

Can I use the 84 wiring diagrams to fix the 85 BRAT?

[Is the 84 4wd gl Wagon the same wiring as 85 BRAT?]

[2nd generation, EA81, what size heater hose?]

which hoses? I think they are the same throughout but not sure

I the ones which connect to the heater core.  Connect on the driver's side firewall.

[85 BRAT, low voltage, could the alternator be the only culprit?]

How many miles on the alternators?  They typically wear out a brush right around 150k miles, causing low output.  I've rebuilt several of the alternators since 1988, 150k is very repeatable.  A couple of times the internal regulator or the rectifiers died.

That sounds about right.   Both alternators that recently went bad had well over 100,000 miles on them.

 

[85 BRAT, low voltage, could the alternator be the only culprit?]

I have an 85 BRAT, I replace the alternator six months ago with one from my parts car, '84 GL.  The replacement seems to be bad, with low voltage shown, and light coming on.   

Is there any component which could be making these alternators go bad?   I thought the voltage regulator is in the alternator.

[The video explains it all! Castellated nut spinning!]

I had what seemed like front axle problems.  I can drive in 4wd, but not 2wd.  

The video explains is all.  Parking brake on, engine running, 1st gear 2wd , clutch engaged.  

 

The castellated nut just spins!

[Hard to find coolant leak, used dry ice to find it]

I had a leak, in a coolant bypass hose.   I used dry ice in the radiator to pressurize the cooling system, and the leak became much easier to find.  

 

Video.

[Engine coolant loss, steam under hood, most likely culprit?]

I am sure the leak is not coming from the two hoses highlighted in the image.  Is the center of the intake manifold connected to the engine coolant?

 

[Engine coolant loss, steam under hood, most likely culprit?]

A steaming cloud of coolant was emanating from under my air filter cover, passenger side, this evening!!

See photo for an approximation of what it looked like.   Coolant represented in green.

What is the most likely source of the leak?

Thank you for the response, and thank you for all the posts on ultimatesubaru.org!

 

[EA81 had low oil, now a new sound, video]

My front main seal leaked, and I saw that I was losing oil pressure just as I was on a highway on ramp.   I had definitely driven with low oil for a few miles, but good oil pressure.   

So glad I noticed the dipping oil pressure gauge!

I replaced the crankshaft seal, and topped up the oil.

In startup, it sounded like the hydraulic valves ticked until they were filled with oil.

 

I have a new sound above 2000 rpm, well represented on the video.  

 

Any guesses?

Common problem that one. Tricky if you don’t know what to look for. The symptoms make sense as this being the issue. It’s a relatively easy fix once you’ve got the part.

Cheers

The ignition control module, in the distributor, has a condenser. The 1984 GL does not have points.    Could the condenser go bad and cause the problem mentioned?

Following up on this.

The new 5psi fuel pump solved the problem.

I could cruise at highway speeds all day!

Before it baulks does it sound or feel like it’s running out of power? 

If so, it’s probably fuel starvation of some description. It could be the fuel pump as previously stated. They shouldn’t be too noisy. You should hear it prime then die before starting the engine. After start up you shouldn’t her the pump over the noise of the EA81!

Cheers

I did not notice a loss in power before the balking.  I tried to recreate the problem today, and I was unable to make it balk.

I did some before and after measurements.

Old fuel pump, 2psi (13.8 kPa) at carb, 594 cc/ minute unrestricted flow.

 

New fuel pump 5psi (34.5 kPa)at carb, 983cc/minute unrestricted flow.

The unrestricted flow was from the forward fuel filter, so there must have been some loss to the vapor return line.

 

Is 2psi fuel.pressure a problem with a Hitachi?

Have you ever taken the carb off and soaked it , refreshed it with a kit ? Float needle could be an issue here. My opinion. 

as you mention , the valve that fills the float bowl. 

 

Where are such kits available?
