Hi all,
I am in the process of tinkering with a 544 (no suffix) and have a few questions regarding this machine. Welland ser# 0767xx.
First of all, while the transmission seems to work well, it does seem quite harsh when you put it into gear or change from forward to reverse while still moving. Not all like what I am used to. You definitely want to come to a complete stop before changing direction on this machine. Is this normal or is there a shift modulator or some such that is acting up? Pressure is in the green zone on the gauge in the dash.
Does anyone have any advice regarding these old Allison transmissions? Am I correct in thinking that it's a TT2000 series trans? Any pressure test points and such would be appreciated before I acquire a service manual.
I have only run it for maybe 15 minutes so far to make sure there are no major issues before I spend more time and money on it. I picked it up with a seized (due to uncovered exhaust) engine. I am told that everything was working well but it was retired because the engine was extremely hard to start. I overhauled a newer 329 that was pulled from a combine and dropped that in instead.
No cracks to be found anywhere and all pins seem to be in good shape, including the center pivot. I have resealed the tilt cylinders and still have to do something with the swivel 90's on the lift cylinders although I don't think they are all that bad.
Sorting wiring out now... almost there...
Any and all opinions and advice welcome.
Thanks,
Marv
