3416H vickers

Recommended Posts

Hi, I have a 3416 with a vickers rear end. Even though the system is adjusted properly it is very slow to back up. In fact if I am on a hill and attempting to back up at times I am not able to. Does anyone have a suggestion as to what I can do to get more speed in reverse. The shift still has second level which locks the shift in place. The tractor goes great forward. Again the problem is backing up a hill. No the hill is not that steep. In fact my 7012H has no trouble backing up the same hill. Is there any way to increase the travel of the shift arm to give me more speed / power in reverse? Thanks. Rick..........

Hi, This is a fairly common problem with these. The same thing is happening in Forward, only it is masked. Since reverse has about 1/3 of the travel that fordward does, forward still goes but not as fast as it should. Most of the play is usually in the little link with the 2 ball ends tha goes to the actuator arm on the pintle shafts. This plus fixing slack elsewhere in the linkage should fix it. Al Eden

Have you checked the fluid level in the res? If it's close to out tilting the tractor forward could suck some air and loose charge pressure. We have so little trouble w/ the vickers it's tough to narrow it down with no more info than this. You may have a very worn main pump and be looseing charge pressure from this. Does it vary with engine RPM? One way to check this would be to go forward and only move the control the same amount as you can in reverse. What I'm getting at is to develope more of a pattern as to when and not it's giveing any problem. You might find it's acting up more of the time then just on the hill and see what compensates for it.

I would try this adjustment procedure as it has helped me with simular situations in the past. I just changed a vickers pump 2 weeks ago because it would not back up a slight incline as well. It would do it in forward but not in reverse. All that it had to do is go up a 2" slope from my driveway to my garage floor.I believe Dave is is correct about the pump being worn. The vickers leaked very very slow out of the pintleshaft. I happened to have another vickers on the shelf and it hasn`t leaked at all as of yet.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
