It would be nice to have the details of the 1545 lock up torque converter control. Does anyone know how the hydraulic pressure is controlled inside of the valve body? I think most Allisons now use electronics, but the 1545 is hydraulic..... Hey Rusty???

No, go back in this thread and it gives the shift sequence. Going from 2 to 3 the converter is unlocked. Then the converter locks while in 3 and is locked when going from 3 to 4. That puts a lot of strain on the 4th clutch pack that could be avoided. The parts I reference are high...

The A3 is a redesign of the A2 and A1, but eliminate shifting. By the wisdom of the day, they took a good performing commercial Allison 545 and added the feature of the locking TC, calling it the 1545. Probably the reason there is a different thunk between 3rd and 3-4, is that the 2-3 shift...

The 10-32 screws holding the V are epoxied to the fiberglass and the aluminum V is held well, directly against it, with washers. I'm not sure the 3/32" rod should be 1/8", but will try. The first bird standing on it..... I'll make sure one works before building the next.All pars for it are...

I salvaged the pipe tower about 12 years ago with my boomtruck when a friend needed it removed. It's been modified with a hinge and gives me about 40' on this very directional antenna. Yes, I have ran my location through the station locators, have Fort Wayne due east at 65 mi and Chicago at...

Building a 16 bay dipole antenna to get over air digital TV...hope it works. I'll build another for Chicago stations if this one, pointed at Fort Wayne, performs well. Notice the use of fiberglass seat components. It's really rigid. This is in-process build. I have a lot to do, putting on...

Yes, trailer and truck are the same (if OEM). There are a lot of 9.00 that would make the trip and are left over from someone going bigger. I would not change until you have a plan and know other issues are behind you.

Yes William. The photo of your A2 and my A3 is the position I thought was used with the budd duals and the A3 singles, dish in. Recovery4x4 says budds run with the narrow setup... I didn't know that. They sure ar too narrow for a bud ran as a single.

Recovery4x4, Your second truck photo has them in the outer position, wide, where the first truck is narrow like your hub detail. Mine is standard for the A3, but from what you say, the budd duals on A2 have your hub detail as "standard". Flipped is relative to where one starts. Your second...

To have the dish out (rear) with my A3 wheels, the hub needs turned to the narrow position. Bearing is in proper position then, about center of the tire. The "standard" position is not dish out on the A3, it is dish in, as shown. Putting the hub at the wide position and dish out is not...

Here is my A3 rear wheel and the axle removed. The standard position is with the wheel dish in and the hub in the wide position as shown in the photo. Yes, to turn the wheel to dish out, the bolt holes need chamfer but the hub needs turned also so the flange is in the narrow position. Photo...

That makes sense. As far as air, there is forward and reverse, but with air dumped, the spring takes it to neutral. I'll concede but still don't recall a neutral position.

Personally I like fine, gr8, machine washer under the head and a flange nut (can be hard to find in fine thread). Really, compared to the wheel studs, any combo works for strength and is unlikely any will come loose. This bolt is holding the steel adaptor plate to the thick aluminum wheel...

If he sold it without the trailer, the purchaser, like a guy with a hummer...would want it unmolested.

They haul perfect on a uhaul car trailer with straw bales in the wheel tracks...for recovery....like if you sold it without a trailer. A regular PU can pull one long distance.

my first impression was the sprag engaging for the wrong direction. My 817 is long gone but I had the tc apart and don't recall an access plate.

The sprag clutch uses air to shift forward to reverse. It could be in a bind if it is not shifting...possibly.... You should research the tranny. Tthe sprag is a one way clutch that releases the gears from a difference in gear ratio back 16/1 and front 17/1 or something like that. Can you...

Have you tried the exterior house paint? Try a sample, it works amazingly well.

What I'm asking is why you thought the 5" M105 axle needed changed?? That is a lot of work. Sorry, reread the first post and was answered.

I used a 7k dexter trailer axle on one and ran the 8x6.5" hmmwv wheels. I use the ford van wheels on my 1101 weld trailer to bring it down too. If I remember, the bearings of a 105 are rated 20k each, so I've never thought of it being light duty. In fact, I'm building a tandem with 2 m105...
