Hi,
I bought a 5 speed transmission to replace a badly broken 4 speed in a tractor / loader / backhoe. That was the reason, I could afford it! The loader is (estimated by me) to be 2000 to 2500 pound lift and has about a 1 yard bucket. The backhoe is 14' depth capable. But the previous owner was stuck in the mud and rocked back and forth to get out and must not have meshed the gears real well. What a mess! At least 31 teeth from 5 gears were knocked off and more were chipped.
Well, I was told that the parts would be about $2200 by the local NH dealer and not available on the after market. So, I found a used 5 speed with live PTO and a double clutch. First stage (peddle going down) disengages the drive wheels, second stage disengages the PTO.
Well, it was in great mechanical condition, but greasy, dirty and painted poorly a couple times. So, it got pressure washed, scrubbed with a wire brush by hand, washed some more, scrubbed some more, degreased with simple green until it was down to bare metal and multicolored paint. Next was a chemical stripping to get it down to bare metal. I don' t know how, but even after all of that, it was still greasy and dirty in spots. So, more degreasing and scrubbing and rubbing with solvent to remove all trace of grease and oil.
To keep it looking new and rust free far into the future, I have gotten into the habit of using a rust protective coating before priming. It turns the metal black like gun blueing and leaves a hard protective finish, but is able to take paint well. Then it got two coats of ford blue enamel with high gloss hardener. All spraying done with automotive spray equipment to give it a nice lasting finish.
Of course, a 48 year old transmission is going to have some wear and tear, right? Well, yah, but the only place that had any wear was the shift plungers. What the heck are they? When you shift, the lever stops with either a crisp snap or a mushy feel. The shift rail has depressions machined into it that the shift plungers snap into under spring pressure. Well, if the rounded end of the plungers are worn down, you get that mushy feel. If they are new, you get a crisp snap as it holds it firmly in gear. The trans had worn plungers, so I replaced all 3 with new ones from New Holland. I think that this is a point that many people don't know about and for the small amount of money and less than 1/2 of time, it’s a no brainer.
The following posts have pictures from the operation. It came out pretty well if I do say so myself! Of course, now that I have the 5 speed looking great and ready for the next 48 years of service, I have found all the parts needed to repair the 4 speed. (Don’t you just love the dealers that stretch the truth a tad on parts availability?) So, the 4 speed is getting a complete overhaul next, and will be going back into it’s original home, but that’s a different story…
These pictures were here previously, but I inadvertently used some proscribed verbiage and the thread was removed to allow me to correct the error.
