Why Is It Difficult To Shift Hydrostatic Transmissions

[powersrp]

why? the same reason toyota has a 12 year old tundra, money, it works, the machinery is paid for, and its tough and reliable. wait for it //:::: the biggie,,, people still buy it.

Toyota also sells precious few of those Tundras, so there is that aspect to consider. Yeah they save money selling the same old truck year after year, but how much more money could they make selling more of an updated model?

What they need is an updated model that is far easier on gas then what they have right now. These things are pigs on gas.

The next gen Tundra will have a 3.5L V6 twin turbo like a Ford EcoBoost. That truck is a year or two away. Not sure how I feel about that, not that I’m buying a Toyota anyway. At least Ford still offers a V8 if you want it...

I've owned many Toyotas both cars and trucks even built my own years ago. It turned out to be an 81, 82, 83 and 1988, bits and pieces from each year. I've never said a bad word about any of them. Wife and I spent many hours 4 wheeling back then with the truck I built.

That would be fun! Both the building and the 4 wheeling!

It was a great time but expensive. I've always said I'd be a fairly wealthy man if it weren't for my addiction to gasoline. Just heading out to pull the bearings out of my boat trailer now so you're welcome to tag alone and pack the bearings for me.

Those old Toyotas were pretty good off road. I used to off-road a lot in my modified 1992 Range Rover. The Toyota used a similar hardened chrome swivel ball around the axle / CV joint if I recall.

Yes they did have CV joints. I'll tell what was great off road were the old Suzuki Samurai. They were so light and short wheel base, great as long as your back could take the pounding.

Yeah, those Samurai were perfect dimensions...but otherwise a rough, crude vehicle.

The HST on the RTV X1140 is almost impossible to shift under load. As stated above, the secret no one tells you is to push hard on the brake pedal for a few seconds which relieves the pressure and then makes it a smooth shift. In other circumstances, a blip on the throttle while in Neutral also makes it easier.

Gears need to slide by each other in order to perform a shift.
To accomplish this with the most ease, and avoid tooth b;locking, it is best if the gears are rotating.
Since the GEARS in question are down stream of the hydro unit, it is best if the tractor is just moving. rocking will do. It doesn't take much.

With the tractor stationary, and the hydro unit static (input to the gear box stationary), if the gear teeth obstruct each other's passage, there is no possibility of engagement. The gears have some "leed" to them, so forcing the shift lever can produce results, but WHY?
Rock'em Baby!

The RTV transmission sometimes stops with gears not in a position to immediately mesh. It may help to VERY LIGHTLY touch the accelerator pedal briefly to relocate the gear-teeth…. to move the gears into a meshing-position. (This particular issue is most evident if the gear selector lever doesn’t easily move into the proper detent.…indicating the gears are not meshed.)

Also, the RTV has a HST pressure release valve at the aft-most position of the transmission. When the brake pedal is depressed… a cable which runs from the brake pedal mechanism (just forward of the firewall, under the hood) runs to the HST pressure release valve. If that cable is not properly adjusted to actuate the pressure-release lever then it is difficult to shift.

Always come to a complete stop…and depress the brake pedal …. to change gears.
