1572 help

[cjohnston]

Need some help here guys. I have a 1572 which had a bad vibration in the driveshaft. This ended up causing the seal to leak on the charge pump input shaft. This weekend I tore it down and rebuilt the drive shaft. I had to take the charge pump off to get the old seal out and replace it. When I got it all back together and fired it up. it had no hydraulics. No lift, no forward/reverse, nothing. Where should I look first. I'm completely stumped.

Thanks, Clay

You either have the charge pump on upside down or you lost the pin that connects the rotor to the shaft. I'd take off the 2 bolts that hold the charge pump on and spin it 180 degrees first and see if that works.

Thanks Matt, I'll try rotating th charge pump this evening. I didn't know that it mattered.

I found my problem this evening. There is a pin under the gyrotor?? inside the charge pump. I found it on the ground and got it back where it belongs.
