Plus Five

OK,
working from the inside of the firewall, I want to get all of the wiper and washer parts into place.

The washer nozzles I made from stainless steel. They have a threaded base with a small o-ring to seal to the cowl. I tested the spray pattern in the sink.

[donandal]

I also mounted the wiper system. I made a new transmission for the wiper rods and used new style ends that have the plastic socket and steel ball fittings.

I made some trial dimensions on paper then made new arms for the pivots. The original spline shaft seemed kind of flimsy so I got donor arms from a ford escort and used the splined shaft. I turned down the shaft to fit thru the original wiper barrels and made new bronze bushings. With a little high school math, I was able to come up with a dimension for the bellcrank on the motor that gives just the right amount of sweep.

I bought two wiper arms and modified the ends by heating and bending them. They cover the entire sweep of the window now and the 12 inch blades reach nearly top to bottom as well.

The motor is a newer chevy type that has high, low and intermittent. The whole setup just clears the cowl motor and the defrost vents and leaves room for the radio.

all finished..

Respectfully, I don't think this is going to happen. ...from your first post in this thread.

Impressive engineering and execution! The drain idea is a good one too.

Thanks,
I'm not done yet...

The electric, brakes/hydro-boost/power steering,air conditioning and transmission stuff is all new to me, so we'll see.

[donandal]

Today I installed the steering column, brake booster and master cylinder.

[donandal]

and the booster...

[donandal]

the hydroboost has three ports. The yellow one I believe is the low pressure return to the reservoir.

The white and green are both high pressure I think, but not sure which is input and which is out put.

I think the high pressure output from the pump goes to one of these, then from the hydroboost to the steering rack, then back thru the cooler to the reservoir.

Does that sound right?

Here is my cheat sheet!

perfect,
that's what I've been looking for.
Thanks

[solidaxel]

Look for a 2003 power steering pump with three openings on the "can", 2 returns, if you have not looked at pumps, depending what front brackets you have

Don, Where did the brake pedal assembly come from? I have the same cheat sheet. This a great build lots of good stuff to pirate. Thanks NC

The brake pedal bracket is from a Ford F150 pickup. I sawed if off flat on the back and made a new back plate with the correct center hole and bolt hole pattern. Then welded it up after mocking up the proper depth for pedal travel and steering column clearance.

You can see the weld in this picture.

There is a sheet metal U shaped channel welded to the firewall for strength. Then the brake assembly bolts just inside that.

I think it has been said many times.... PHENOMENAL!!!! = STUNNING Fabrication work here, thank you for sharing with us all.

Thanks,

I appreciate your comments.

A couple of questions for everyone.

With the corvette rack and pinion, Chevy hydroboost and late model power steering pump, what type of power steering fluid do I use?

Also, is there any bleeding of the power steering side of the hydroboost, or does it bleed itself?

What size cooler and what type of cooler? fin and tube or plate?

[solidaxel]

I am going to use Power steering fluid
I think it will bleed the same as a rack, at least I hope it will, jacked up front end slow turn left and right lock to lock with the engine running check and re fill
For the PS cooler I removed the cooler from the Tahoe I got everything from 2003

[donandal]

Isn't there the red stuff and also clear fluid too?

Is it all the same? Is it interchangeable?

[solidaxel]

What front alt and PS bracket are you using?
Which pump and reservoir did you use

I am having a clearance problem with my pump pulley and rack!

I used Kwik performance brackets. The pump is just a stock type GM pump.
It was recommended by Pace performance. I'm not sure it would have enough clearance for a pump that has a reservoir attached.

Alternator is just typical GM style.

OK,
more questions,

My transmission ( 4l65E ) has two quick connect fittings that look something like this.

The radiator has two threaded ports on the side for the transmission cooler.

I think I would benefit with an additional cooler before fluid goes back to the transmission.

How much pressure is in these lines?

How do I connect to these transmission fittings?
What type of hose?
What type of cooler? How big?

I have no experience with this stuff, and there seems to be about a million fittings to choose from, of which I'm sure most would be wrong!

Thanks

don,

I remove those fittings from the transmission and use pn 7304988 from Napa. It is the same for a Thm350 or 700r4. The 5/16 steel line connects to that fitting with a standard brake line nut double flared on the line. Routing is typically along the trans and engine forward to the radiator similar to OE.

While I have never measured pressure on this circuit, many transmission coolers connect with a barbed fitting and clamp to a rubber hose so the pressure isn't substantial.

Your radiator sounds like it has a transmission cooler in it. Typically those are sufficient for keeping the oil cool enough, though touching base with the radiator manufacturer for additional recommendations based on how you will use the truck wouldn't hurt.

[donandal]

Thanks,
I guess I need to verify my radiator fittings and see if the transmission came with any fittings then get out my Visa card.

[Iplumb]

On our 700r4 I believe the case is tapped iron pipe size (IPS). We bought adapters, fittings and stainless braid along with 90s and adapters for the radiator - inverted flare for those if remember correctly. Summit cost was about $90 I think if that helps.
You can see them in this picture. They still need to be clamped in place.

Not sure what you have for a flaring tool but a Mastercool one will make the "flares" for the quick connects. That said I swapped mine out for inverted flare ones too.
