Success!
I finished all four rear hubs, adjusted the brakes, cleaned the axle vents, and put in fresh 90wt in both rear axles.
The hub temps are 115-120 after about 12 miles at 45-50 MPH.
I still have to do the front hubs, but that ain't likely to happen tomorrow. Wife is home from Florida...
Re-set the preload on the rear hubs this morning. No test drive yet, but I'm pretty sure I've got it nailed down now.
I went on with the middle axle and figured I'd get that done today before the wife gets home from Florida.
The right middle hub was filled with 90wt. Not much evidence of...
Steven, I'm going to get back into those hubs again today. I read through the TM's last night and I don't see a torque spec for the adjuster nut. I see a torque spec for the lock nut but that wouldn't have any effect on bearing preload. Am I missing something?
The TM says to tighten the...
Ah! I finally found my old post with all of the part numbers that I used for my Pyro. This is by no means the only choice, and some prefer a mechanical gauge versus the powered gauge, but here some info that you may find...
Here's what I did with my Pyro install:http://www.steelsoldiers.com/showthread.php?80515-My-M35A2-Project-aka-Big-Betty&p=1115440&viewfull=1#post1115440. Search for "pyro" and "isspro" and there are dozens of threads about pyros and installations. I used a Isspro R17021. If you go with that...
The left side trunnion was nasty. The right side wasn't so bad. Instead of breaking it all the way down, I scooped and washed as much of the peanut butter out as possible. Then I pumped fresh grease in until clean grease was coming past the grease seal. I'd really rather disassemble them and...
Finally got to finish the right rear hub. It's back on with fresh seals and fresh grease. I cleaned and checked the axle vent and adjusted the brakes on that rear axle. The diff is filled with fresh 90Wt.
Next I'm checking and servicing the trunnions and then moving on to the middle axle.
Got the hub and bearings cleaned up and guess what? Yep, here comes the rain again!
This hub was not nearly as messy as the left rear. The intrusion of 90w was not bad, so the grease was mostly just grease and not the grease/90wt/water/peanut butter that I had on the left side.
Finally getting back at it on the hub servicing. Working on the right rear now. This hub had 90w intruded into the hub as well. This one also has some water droplets. Again, there has been no external evidence of a problem. No gear lube leaking out, no heat problems, and no bad noises.
I am...
The rain has my driveway mechanic shop shut down. Its raining off and on with decent periods with no rain. I really want to get back to work on servicing the hubs, but I know as soon as I get the tools out and get started, it'll rain again. Blah!
I would personally prefer to have the gauge and know for sure, rather than assume it was ok. That being said, I would think that a non-turbo engine would have lower EGT temps, but I have no experience with a non-turbo deuce.
Aluminum melts at 1,221 degrees F. In my humble opinion, I would keep it below 1200 degrees for sure. I personally consider 1000 degrees to be the limit for extended operation. That gives me a couple of hundred degrees of safety margin. Here's why you don't want to run it too close to the 1200...
I agree with Gimpy on putting the pyro on the steering column. The temps move quickly when you're pulling hard and you need to be able to monitor the EGT within your normal field of view.
If I were in a hurry, this would seem like a lot of work. As it is, I work on it for 2-3 hours and then I go do something else. That saves me from getting tired and frustrated. I'm not worried about finishing, I'm just doing.
Having a bit of concrete to use is nice. I have a bit of slope to...
Thanks, Clint. I had a 50/50 shot and I guessed it right!
What you described for setting the bearing preload sounds about right for what I did. I cranked it in there pretty hard and then backed it out again. I tightened it up until I couldn't feel any lateral movement by rocking the tire back...
Here's a couple of photos of the outer seal.
Does this side (Side A) go toward the bearings, facing inward? (This is what I chose.)
Or, does this side (Side B) go toward the bearings, facing inward?
I guess I could just go ahead and open the other hub on the rear axle and look at how it is...
I quit working on the truck yesterday to go watch my boy ride a 4-wheeler and then join him and his "Poppa" for some dinner. Have to work this afternoon but I managed to get the right rear hub back on the truck with new seals and fresh grease this morning. I used "The Right Stuff" to plug the...
I got the goo cleaned up and I'm starting the reassembly. The shoes are ok and I can live with the drum condition for now. If the rest are in this condition, I'll plan a full brake job for later this year.
I decided I should do at least one hub on my own before I had Clinto do the rest. I wanted the experience of doing this and hey, maybe it's easy and I can just do them all. Not.
Well, the work isn't bad. I had the first hub (left rear) off in about 10-15 minutes. I found that the inner seal...
