Gamma Goat wheel hub Maintaince

[Joe Gamma]

Just starting taking the Wheel hubs / brake drums off my goat and learned quite a bit today. I figure to take one wheel off a day and really inspect / lube it.

Is there any recomended maintaince...I took the rust off the drum and cleaned it with brake clean...Noticed there was infact a gasket missing around the entire hub...

Hub looked heavy but was not unmanageable at all...

any recomendations before I start the rest...

Thanks Guys..

I started on the front two of my goat but decided to wait for cooler days, this OKlahoma 110 days not for me. I plan to reline brake shoes, replace rubber lines, replace cylinders and use dot 5. So far I replaced the master cylinder. I was trying to figure out easy way to replace the rubber lines. The coil spring kind of in the way.

I started the noble goal of a wheel a day....The old Coot who really restored the Goat said he took of some Hubs and they looked fine a year ago. Oddly when I gt My Goat the three brake inspection ports that take the three quater inch drive were missing on the right side...

The Hubs on the left were immaculate..the three on the right were shot with bald shoes....Glad I insisted on pulling each one..

Gonna try and replace one drum with two blown out 7/16 screws and a cracked flange before I try and weld it...

A bad day working o the Goat is always better than a good day at work...

Thanks Gamma Goat one for recomending 715 shoes...

I bled the brakes but before I go futher does anyone know anything unusual about bleeding them..being trctor and trailer..

You're welcome.
Nothing strange about bleeding. Farthest from the master first. Be real carefull about removing the bleeder hose, one drop of "sillycone" will destroy the shoe. It's one of the best lubricants known and doesn't belong on a brake surface. Finger tight the axle center bolt to assure axle engagement in the wheel. Make sure the jacking bolts are completely backed out before tightening the brake drum. That's what brakes em. After torquing the drum bolts tighten the jacking bolts. Then retighten the axle center bolt and lock it in place.

It's still GamaGoat...

A pressure bleeder makes it so much easier. My last goat"s brakes drove me to near insanity. LOL I just love pulling off the wheels and drums. Im pretty sure sel-adjusting drum brakes were pretty common back then, sure would have helped on the Goats! LOL

 

[Joe Gamma]

I used a fancy bleeder yesterday and after my Gammagoat told me to kiss its Fanny I went old school and bled them all with a buddy.

I thought I had them adjusted well enough but the test ride showed one doing a ton of work and two others doing nothing.

Is there a special tool besides a screw drive to adjust goat brakes?

I jack the wheel up and adjust the wheel till it did not spin and then backed it off till I felt it scraping(heard).

Does anyone have a process they find simple to adjust them..

Thanks Guys it takes a whole Villiage to prevent an Idiot..

[m561gamagoat]

After bleeding and adjusting you need to drive around, adjust again etc, till everythings finds it's equilibrium. Big flat blade works as well as anything. And there is no simple process just gotta keep at it

 

[Joe Gamma]

Well now I can sew on..ok Liquid nail my Gamma goat brake merit badge.....Buddy adjusted them all again yesterday and was quite pleased when I showed up this Morning...I took it for a good ten mile ride and marked half way the Drum to hot to touch...the Lazy cold one and another pretty hot one that was not steaming though..Brought it back and three adjustments later my Goat has a **** hard pedal and will stop better than it ever has....

Now for steering..

Thanks folks!

Sounds great,
I just completed rewiring the dash according to the schematic. Also put in an electrical kill switch.
Connected the batteries and no smoke, everthing electrical working now. 100 degree days this week in OK so brakes repair still on hold.

 

[Charlie 6]

Let us know how the steering goes, what do you plan to replace?
When I got my goat It came with a new steering column, I have it on the to do list.

 

[m561gamagoat]

Speaking of steering, are the seals used in the steering gearboxes tough to find or find a replacement that fits? Anyone know? My rear box is leaking pretty good.

Hey Joe , the solution to the missing inspection port plugs ( they are just BSP steam plugs, can get them at all good plumbing supply oplacess is to drill a hole through the square head and then safety wire it with 32 thousandth stainless safety wire to the other plug,use the around the head meathod and ensure it pulls positive. There is a recommended tool you can make for brakes, both adj and bleed in the TM. if you dont mind my asking where did you source your drum?

 

[Joe Gamma]

Sorry for my late reply...I sourced it from Arts Parts in Minnisota ..he is all over E-bay..

one of the guys I saw last year put Zerks into his boxes and pumped them up with Grease. he says that they work great and keep the water out.

 

[goat whisperer]

Graphite grease will work pretty good...

For those that have done this before, any suggestions on an easy way to get the drum off? I've unbolted it completely but it still won't budge.

 

[doghead]

Jack bolts in the jack bolt holes in the drum.

With some pressure on the jack bolts, you can hit the center of the drum to shock it if needed.
Also, be sure the splines on the drive hub are not frozen(spray lube in the center hole and use a punch to make it move in a bit to know it is not frozen).

One of mine, I had to grind the splined hub rivets off to get the drum only off. Then I had to heat and pull the splined hub off the axle.

You're just full of cheerful possibilities. Of course being the pessimist that I am, I'm sure mine will be equally challenging.

 

[doghead]

Gee, I left out the gorey part.

Before I resorted to grinding the rivets off, I was using a 3/8 drift punch in the hole in the hub, trying to break the axle free from the hub.

Never swing a 12# sledge hammer into a 3/8 punch.

It broke and hit me in the forehead leaving a perfect circle(hole in my forehead).

Why do head injuries bleed so bad?

6 stitches later, I moved on to plan B.
