Member Projects / Ladder bar setup
« on: October 01, 2025, 09:17:04 PM »
My pinion was down almost a degree, 0.8.  The engine/transmission is down 5.2 degrees.
I removed the ladder bars and measured them, finding they were set at slightly different lengths.  I shortened the shorter lower bar 1/4" and made the other lower bar the same and made the upper bars the same.  After putting them back in place I found the pinion was pointing up just under one degree. 
I pulled them out and made the lower bar 5/8" shorter.  The snubber had to be removed as it was against the bracket over the pinon before I could get the ladder bars back in place.
Now the pinion angle is 2.8 degrees up. 
I cannot take much more out of the lower bars so I will have to lengthen the upper bars if I want to raise the pinion angle. 
My drive shaft length will be about 42 inches. 
I did remove a couple of leaves on each side in the front springs to loosen the front end.  And the car doesn’t have the doors, radiator, and the complete engine in it yet so maybe I’m getting ahead of myself. 
I think I will wait until I have the car closer to completion before I adjust this anymore.

No one had an answer to my question on the throwout bearing isue in the my last post so I emailed the McLeod help guy asking about the failure of the throwout bearing to retract from the pressure plate fingers.

His response was quote:

Thank You for your support of McLeod Racing.

Your question is very common amongst people that don’t know how the hydraulic bearing works.

When you initially install the bearing on the guide tube and measure your “A” and “B” dimensions to set your air gap.

Lets says its .200”

You then put fluid in the system, bleed all the air out of the system, and then press the clutch pedal to dis-engage the clutch the first time.

From that very moment, the .200” clearance originally set has now transferred to the backside of the piston.

The bearing will be constantly riding on the fingers for its entire life.

Now. As the disc wears and the fingers rise towards the bearing, the fingers push the bearings piston back into its cylinder bore and back to a compressed position.

This design is very similar to a brake systems calipers and their internal pistons that actuate the brake pads against the rotor.

I hope this helps.
 
Kind Regards,

I am surprised at his statement:  "The bearing will be constantly riding on the fingers for its entire life."  It seems like the bearing life will be short, but I guess I'll find out.

Having fun with the McLeod hydrualic throwout bearing. 

The first one leaked and was replaced.  Both were very hard to slide on to the TREMEC T56 Magnum six speed's transmission guide tube.  They fit so tight that the light coat of paint on the guide tube came off in several places as they slid on.   Got the initial adjustment done without any problems.  The transmssion went in OK.  I had to buy bolts because i wanted a full thread bite and I wanted washers under the lock washers so the lock washers couldn't dig into the aluminum case.  Discovered the rear tranmission mount will accept the toploader mount and built a cross memeber and frame mounts. 

But all is not well with the throwout bearing.  Bleeding the throwout bearing did not go well.  Took several tries as the drain line would pop off and the small master cylinder would go dry.  Had to use a long line that went clear to the floor (the car is on my lift) and a hose clamp to keep the line in place.  I still managed to let the master cylinder get dry and had to start over.  I finally got the pedal to stay off the floor. 

Now the travel is only about 1-1/2 inches, about what I expected.  But the throwout bearing stays on the fingers of the pressure plate.  I thought it would retract when the pedal comes up to the top of its travel. I used a long skinny screw driver to reach in and lightly pry it back and it did move back easily.  I'm working alone and cannot see if the pressure plate is releasing the disks. 

Is this normal for the throwout bearing to remain against the pressure plate fingers?  I have no experience with these multifinger pressure plates.  I've only used the long style with three fingers.

I still have to build a pedal travel limiter/stop. 

And this is just a mock up engine. Just a heads and a crank to mount the flywheel, etc in the back and a front dampner to let me setup the pulleys, etc in the front. I'll have to do all of this again when I put the real engine in.

FE Technical Forum / Re: Valve Adjustment Advice Needed
« on: September 26, 2025, 09:34:59 PM »
http://fordfe.info/ValveAdjustment.htm

There is an easy way and the official, book way.   Forget the official way.

With the engine hot, remove the valve cover.   Using a remote starter switch bump, the engine over until the Intake valve for cylinder No. 1 is just starting to close (is coming up).   Adjust the No. 1 Exhaust valve.

Then bump the engine around until the Exhaust valve is staring to open (going down).   Adjust the Intake valve.

If you are slow at this or your battery is weak, drop the valve cover on and run the engine for a minute or two, to warm the engine and recharge the battery.   Repeat the above steps for each cylinder.

This works because if the intake valve is closing, the exhaust valve has been closed for about a half stroke or 180 degrees of crank rotation and won't begin to open for 360 degrees of crank rotation, and when the exhaust valve is opening the intake valve has been closed for sometime (360 degrees of crank rotation) and won't begin to open for 180 degrees of crank rotation.

I need a transmission mount for a Tremec TKX 6 speed.  I tried to fine one on their site but they don't list or even show transmission mounts.

Summit doesn't list one on-line.  I hope their sales agent knows what will work.  I need to build the cross member.

Thanks

I don't expect to compete for any class records.  I just want to make some quick and fast passes.  I would be very happy to get into the 8s.  I think the mid nines might come but a lot depends on how quick I learn about setting up a coil over suspension.

It started out as a gasser project.  But the rules for A/Gas today is only one carb, so that's out.  Maybe Competition Coupe but I haven't verified the carb limits there.

Or some tyoe of AFX nostaglia car. 

I just want to try to see how fast and quick I can go, setting personal bests so the class thing is not important.  I do not expect my eighty year old reflexes will get me more than the first round in any class.

The original brake master cylinder’s output fitting does not seal, i.e., it leaks.  Teflon tape does not let it get tight.  It took me a couple of hours to pin down that the fitting has a 3/8-24 bolt thread, not a pipe thread.  And this thread is also used by the smallest 3/16” brake line fittings (tubes).   However, there is nothing inside the master cylinder port for the fitting to fit against, so it doesn’t seal.   It is not a metric size, but the threads almost match an M10-1.25 bolt. 

The fitting apparently was made by someone as it seems to be two fittings brazed together.  It only has  a threaded length of a quarter inch.  The port is 3/8” deep and threaded.  The master cylinder casting marks are US Brakes but I cannot find them via an internet search.
 
I think I will disassemble the master cylinder, drill and tap the port for a ¼” pipe fitting and then bush it down to use 3/16’ tubing.    If this doesn’t work then I’ll just replace it.

Would those work with a standard 3.5 crank?

Well my budget doesn't let me go biggera this time.  I wouild like to but they wanted $1200 for a 4.71 ring and pinion set in 35 spline s no one is making them now and that was the price for their last one.

Somebody recommended "Quick Performance" in Ames, IA for gears and axles. 

I just recieved a center section "pumpkin" with a Strange nodular iron case, 35 spline Detroit Locker, aluminum pinion support support, and 1350 yoke.  I supplied the 4.71 ring and pinion gear set and they assembled it.  They also supplied the 35 spline axles  I needed.  Less than $2000 total. 

They were easy to work with, had ansers for my questions, and did not hesitate to allow me to supply the ring and pinion.

Highly recommended.

I was going to use a set of Zoom 4.71 gears that I’ve had for years.  28 splines on the pinion for the yoke.   believe my set is the drag race gear set, not recommended for the street.  Is the 28 spline OK for an 800 HP motor.  I didn’t even know they made a 35 spline “Pro Gears” set. 

When do you move from 24 to 35 splines on the pinion?

Thanks

Non-FE Discussion Forum / Coil over rear suspension
« on: June 21, 2025, 12:46:36 AM »
My ’70 Maverick race car has a rear coil over conversion.  When I put it on the lift, the left rear spring is loose, about 11 inches long and right one is tight about 9-1/2 inches long.  They appear to be QA1 but I can’t locate a listing for the numbers on them.  The shocks are nonadjustable.

The front suspension is a straight axle using a pair of leaf springs.  Total weight was 1392 pounds without an engine, transmission, and accessories such as battery, gas tank, headers, etc.  I’m estimating 2300-2500 pounds total when the car is race ready.
 
I’ve never set up a coil over rear suspension.  I looked at several YouTube videos, but none of the videos address why one spring would be completely loose and the other tight.  I am guessing that the preload is correct on the right one add the left needs to be tightened. On leaf spring setups I use a extra leafs on the right and when I setup Air Lift Air bags, I put a higher pressure in the right air bag. 

Would setting length of the left one at about ¼ inch longer that the right be a good place to start?
