I seem to have developed a leak at the output shaft of the Allison B500. I'm on my way to Poteau OK and plan to be there for a few weeks. Can anyone recommend a shop in the area?
Hi;
Try one of the charter out fits in Tulsa. I forgot the name, but it was not Kraft Tours. You should be
able to Google it. If they can not help, then they can tell you who can help, They helped me many
years ago. Good luck, Merle :D
Wagoner Tours between Coweta and Wagoner off the Broken Arrow Express last free exit before the toll road then you all ways have United Engines in Tulsa,Village is big around Tulsa but they are in Owasso
After yesterday going through OK we hate toll roads....... Wow I am glad we had stopped at Costco and got some change as well as dollar bills,

OK has their share of toll roads you cannot get out of Tulsa with paying a friggn toll
You got that right. We are in Waysville, MO at Ruby's resort on the gastraci river...

OK only has a $.05 per gal fuel tax,they have roads you can drive without paying a toll fee but most people like the 75 mph speed limit on the pay slabs to avoid the traffic,I could drive from Tulsa to OK City on the state hiway but it took 2-1/2 to 3 hours for 3 bucks I could get on the Turner Pike and 1hour and 15 mintues I was there a no brainer for me
Yep and they used a long string to set it up, LOL. It is straight as one with only a few transitions.
I ended up having to make an appointment at United Engines in Tulsa. Upon closer inspection I have found that the leak is coming from the pan area. I have found a few of the filter access cover bolts are stripped which is most likely the cause of the leak. These bolts supposedly go all the way through the control unit into the main case, and this type of repair requires a special template be used which nobody seems to have in this part of the world except United. They say 10 hour job @ $158/hr plus parts and fluid. Gonna end up being about a $2000 repair.
JB weld from the inside? Just throwing a guess out there. It's worked small miracles for us & others in the past. Just saying...
2 grand! It may be worth a try?
Those bolts are easy to strip for the DYI guys and a real PITA to redo,JB Weld would bot fix the problem there are 2 filters in the cover and are pricy for the deep pan filters Derrick,bet it will cost closer to $2500.00 out the door
NO JB here. I'd think some high temp silicone type sealant would stop it and still be able to be removed down the road. If super cleaned up, it should seal and stay on fine. Looking at a 2000 repair bill, I would try some other options first. As in plural, there has to be someway to at least slow the leaking if not stop it.
When the bolts are stripped nothing is going to stop the leak except to redo it,the B500 Allision is not your fathers Oldsmobile like the older Allisions those cost around 12 to $15,000.00 installed

I had the trans filters and fluids changed at a freightliner shop about 3 or 4 years ago. Right afterwards I noticed the one filter cover was always a tad wet but not enough that it would drip. I just motored on and kept an eye on it. Never got any worse until last week heading down to Oklahoma from Indiana I started noticing oil spots on the towed. Crawled under yesterday to get a closer look and the bottom of the pan is plenty wet with nothing above the pan wet at all. Put a wrench on all the pan bolts and filter bolts to discover that 2 of them were slightly snug, but would not torque down, just kept spinning. All the rest of the bolts were so tight I could not budge them with all my might on the ratchet. Seems excessive to me. So here we are. Given the nature of the problem, I am just not willing to try shadetree methods this time. I believe I am better served to just bite the bullet and keep on truckin'.
JB Weld or any type of other sealant is gonna get expensive when it works it's way into the trans.
There is a thread repair kit just for those filter bolts. It will be a reliable repair.
This isn't a place for power tools. There is a torque spec for the filter bolts and the drain plug.
Have them hookup to it and see what your fluid life remaining is, You might not need new fluid if it's TES 295.
helicoil?

That seems a little expensive compared to the $900 price I was quoted about six years ago, but United is an Allison dealer plus prices have gone up.
One of mine got stripped, but there was enough thread left to install a threaded stud which has not leaked yet.
Repair was completed yesterday. Drilled and installed 10 thread inserts, replaced several seals and gaskets. Mechanic said that inside the trans was spotless, no flakes or grimy film of any kind. Drove 120 miles back to our current parking spot and everything is dry. I'm happy happy happy. Total cost of repair was $1470.
Back in the shop again. How many times do we hear someone say "go with your first instinct"? Well we put almost 1k miles on and the front of the car was once again full of oil spots. Made an appointment at a truck shop in Scottsbluff NE, where after several hours of investigation they came to the conclusion that the output shaft seal is leaking under heavy power. Weren't able to find it until they pulled a hard hill. Now I sit here in a dirt lot across the street through the weekend waiting for parts. Oh the joys of bus ownership.
