Can someone help us keep the players straight?

Muttsjet - 8MA0642  Car Done?

Lee - 8MA???? Car Done?

Mike - 8MA???? Car Done?

Maugusta - 8MA????  Car Done & Sold?

Thanks…. Hard to keep straight, but I know this thread is for you, and not me…

Switching from injection to Weber's. Easy right? Well, life got in the way and I probably can't touch the car for the next 6 months. When I do get back to it, probably have 3 months of work to do. Otherwise the car is in decent shape.

Red/Black int.

STILL in paint shop, meeting with them tomorrow...  Engine/Suspension/Mechanical restoration (hopefully) finished.  Interior in presentable condition, but it's also on the list.

This is the most popular Mangusta thread AFAIK!

Thanks for the intros!

lee: 8ma1076...painted before covid and me in a half world away with a single visit to the US since. Determined to finish this decade.

   8ma1046 was in the family for a moment.

Ready to reassemble drivers suspension and steering. Can someone confirm best grease to use for steering and how much to put inside gaiter? What is the grease gun attachment called to put grease in heim fitting or should I just get the small grease gun for filling heims mentioned in another thread? Confirm RERS 5 is the correct rubber covering for the front steering heims?

My generic grease gun came with a needle fitting that worked perfect on the Heim joints...  Took a few tries to get it down, but simple enough...

Why are you using chassis grease in your steering? Cam Gears Ltd who built the rack said to use 80W90 gear oil in your gear-driven steering and so does your Owners Manual.

He may have just been referring to the Heim joints for the steering

I don't recall finding any grease in my gear box.........only grease!

Can't imagine the mess that 80-90W would leave on the floor.....those gators are not liquid tight.......

Grease fitting for Heim's was a "needle point" IIRC!   I posted it and a picture, elsewhere in one of my long winded threads!!!

   If you cannot get the original Italian stuff, the owners manual calls out precisely the use of "MOBILEGREASE SPECIAL" for the front bearings and steering rack...Another fine substitute is whatever you have (!).

  So whatever cool stuff PepBoys is selling for wheel bearings, just make sure the heim is cleaned of all old tarnish and then spend some Spa time working the new grease around the joint. I think there is really no point in overpacking inside the boot, work enough to cover the bearing and avoid a grease aquarium.

   Getting the boots over the heims is super simple. Finish by inserting the alignment spaces and voila, good for another 50 years.

I REALLY like the Ford Mercury Wheel bearing grease with molybdenum in it.....

Works well with the very same wheel bearings as the Goose, in all of my other Ford products!!!

I used a heat gun on the Heim boots to soften them up...  Didn't take long...  The boots went from a matt finish to shiny when heated, then slipped right on...   

I agree with Lee that choice of grease inside the rack may not be that critical...  The steering shaft isn't exactly spinning at high rpm and heat build up is probably not a concern...  Just keep it lubed with SOMETHING and you should be fine...  (In my opinion ~ FWIW)

I think on page 18 of the owners manual, it says to replace the grease when the rubber boot crystallizes to plastic and then breaks open....see even older comments on this from smart guys who wondered why DeT used just half a boot (!) But yeah, its hardly as if there is going to be a lot of rotation inside the heim.

The best picture I can give on installation of the boot is attached, the sequence is;

- put the Heim threads thru the small hole.

-take the rod you'll attach it to, scrunch the rubber up enough to catch the thread.

- make a big pull. Rubber is magic.

Back to work after some elderly parental issues...

So, steering rack heim off and regreased with grease gun. Have heim boots and special pliers to get heim boot on.

Am curious, since my jam nut is welded to the large circular metal disc, and I had to remove this jam nut combo from the heim joint to get the jam nut combo into the end of the boot (heim would not fit thru small opening on boot end), is it hit and miss to get it all reinstalled to same location?

I did take some measurements before I disassembled the heim to jam nut/metal disc combo: given the placement of the jam nut combo on the heim joint thread, it took exactly 18 full turns of the heim/jam nut combo to get it off...the distance between the outer edge of the jam nut and bottom of inside edge of the heim body was 16mm...the distance between the inside edge of the jam nut and outside edge of the heim body was 56mm.

Put it back to your measurements and you'll be fine!!!!

Gettin' there!!!!   Steve

Getting there! Need to find a new M12x1.75 locknut, get bearings repacked/ assembled/installed, reassemble and reinstall brake, and then done with chapter 1.

Torques ... used 12ftlb for each of the nuts and bolts holding ball joints to a-arms...sound right? used 60ftlbs for lock nuts attaching ball joints to spindle...sound right?

Reinstall repacked wheel bearings/hub...what is final torque on hub lock nut? Do either of the approaches below sound about right?

...

....as for the wheel bearings....

The Ferrari procedure speaks some truth, but final torque is WAY wrong...   Since you are using "Mustang/Ford" wheel bearings..... I'd go with that procedure in the Ford books as well!

Pantera procedure is close to what you want to do......butt IMHO way too much subjective feel....and GOING AMISS!

Mutt....... you should really go in and just delete those references in your post. Wouldn't want to mislead anyone....Ferrari or otherwise!

BELOW EDITED 8/14/2024 1PM PST

The initial torque tighten 17-25FTLBS WHILE SPINNING THE ROTOR to seat the bearings.  Loosen 1/2 turn retighten 10-15 INCH LBS while again spinning...  This amounts to pretty much "thumb tight!"  Use that new HF inch lb torque wrench rotting in the bottom of your tool box drawer!!!

These are tapered bearings, so they can handle a little preload.  12FT LBs IS TOO HEAVY!!!  Would likely burn up the bearings in short order!!!!  Don't need that!!!

Wrench on!!!!

Picture attached from 1970 Ford Shop Manual- Mustangs Cougars etc.

Thanx much...replacing bolts attaching hub to rotor since I have old bolts out...per various torque spec sources, plan on using 31 ft lb of torque since bolts are M8-1.25 grade 12.9...sound right?

.......I wouldn't go any higher than that in aluminum for a smallish bolt..... secure with at least blue loc-tite.....red if you expect to challenge the braking system on an hourly basis!        Don't want to break 'em or strip 'em!

Fun working on a car with absolutely NO technical references 'eh???    Pantera not even something you can refer to either!

If you can find one of those "torque" charts showing recommended amounts of tight for various sized of bolts, that can come in very handy, but looks like you may have that already!

Some of the factory Ford shop manuals had a section or page with that on it....just trying to think where else.....  Fastenal website could have it....MSC.....  Google if nothing else for a chart.

Gettin' there!!!!

So, which would be better for bolting hub to rotor given I cannot find M8-1.25x28 partially threaded bolts in 10.9 or 12.9 grade

a) 4 bolts 'like the old bolts' that appear to be grade 8.8, M8-1.25x28, are partially threaded to 'match no threads  in hub' (about 8mm), threaded to match the threads in rotor (about 20mm), and will take about 18ft lb of torque

or

b) 4 bolts that are grade 10.9 (or 12.9) , M8-1.25x28, are fully threaded bolts that 'don't match no threads  in hub' (about 8mm), matches threads in rotor (about 20mm), and will take about 27 ft lb (or 31 ft lb) of torque.

Question is which makes for  strong hub rotor assembly, matching the partially threaded old bolts that align with the bolt hole threading, or going with the 10.9 (or 12.9) stronger bolts that won't have bolt hole threading thru the 8mm of the hub?

Disregard...found exactly what I needed at McMaster.

@muttsjet be sure to share what you found if it works.  Useful info!

Dang!   I do not recall what I used for pads in the Goose!!!   I know I put the EBC "street" pads in the Pantera and they perform nicely, so if that is what you have here....you'll like them.   You do not want anything metallic that you need to heat up before you can stop! 

These would be same as a "street 427 Cobra" in the EBC catalog I believe.

Cheers!

And they Grind down your brake discs, almost the same amount as the brake pads… very costly proposition….

for mkeh above...the 4 M8-1.25x30 10.9 bolts attaching hub to rotor from mcmaster worked just about perfectly. Had to grind 2mm off back side to insure clearance with bolt heads sticking out of spindle. Checked across internet and torqued these bolts to 26.9 ft lb using permatex blue.

part number for 25 bolts is 91310A538 for 22.72 with shipping and tax. Bolts themselves were 10.78.

Checked parts manual, but unlike most cars, there was no washer between outside bearing on hub nut. Confirm this is correct? I assume next step is to take a chisel and pound the top edge of nut into the two indentations in the spindle. Correct?

Dialin indicator indicated about 2 thousands of movement after tightening nut and adjusting it a couple times.

Now have pass front end (brake, ball joints, tierod) pulled apart for refurb and new parts, and am comparing it to my completed drv side.

If I wanted to start from scratch on front wheel alignment, is their an initial factory number of turns (my drv side was 18 turns) for the heim connected to the rack? Additionally, my drvs side tie rod was 57mm from outside edge of tightening nut to center of tierod joint (the pass side is 69mm). What is an initial setup parameter for the tierods?

Once rebuild complete, I'll perform a manual home alignment and then take car to the shop for an accurate alignment.
