1450 hydro question
 

As some of you might have seen, I've got a 1450. The nice weather has finally got me some time to work on. Long story short, I've got the engine running in just about tip-top shape. My question comes from they hydro.

I've changed the fluid and filter as well as adding a washer here and there between snap rings and cam control assembly's and damper plates to fill any lateral play they may have. I've also tidied up the trunion by fixing the groves typically worn in it as well as new springs and ends. Things are 1000% better on this machine between when I got it but now but I still have a little more play than I'd like. It really only comes into effect when the tiller is in the ground. When the tractor encounters any real resistance (whether tiller in ground or on a steep hill) it'll act as if there is hesitation. The tractor will slow or stop until I give it more speed with the hydro then it'll move again.

Is there anything I can check with this? I've got some time this weekend to work with it so any suggestions are appreciated. Is it possible part #1, #6, or #6 could need replaced (I've never seen one so bad it did but I'm grasping at straws now)? Maybe some adjustment I've overlooked? Thanks guys! :beerchug:

I've seen #1 and #6 wore bad enough that they had to be repaired or replaced. From what you are describing, it is worn linkage. We repaired one a couple weeks ago on the 169 that my friend Chris bought. It was doing just what you described. We repaired the square hole that the spring fits in (trunion) and replaced the springs. It fixed that one to like new. You may still have excessive wear in the linkage pieces.

I'm thinking it's beyond repairing the square hole the spring fits in on part #1 as I've done that and replaced the springs so I suppose I'm looking at part #6. I'll try to get some pics this weekend when I put some more wrench time in. She runs good until I load the hydro up but when I do, there is hesitation.

The pressure valves may be getting weak also...... :bigthink:

put a 1/4 in. washers on the end keepers for your 2 springs, this will shim the outer spring to the same length as your small inner spring and remove the end play. this also will make your hydro more [touchy].

When I repaired my trunion, I repaired my #6 plate because the groove was 50% wider than the pin near the neutral part of the plate. This helped, along with the trunion repair. I have still notice slack and drifting near neutral depend if I go rev to N or fwd to N. I am going to repair the #1 plate as there is a 3/16" of slack between it and the engagement of the trunion springs.

Thanks guys! I'm going to try and get a better look at things today, grab a few if I can. If I remember correctly, when I put the new springs in the trunion, they were snug, don't think there's much play there.

As for the pressure valves, you're talking about the relief vales, correct?

Correct. :beerchug:
