Hi i have a 1955 Allis Chlmers CA farm tractor that ive done alot of work to. The problem is the lift will go up fine but won't go down unless i crack a hyd line. Im sure thats not safe but i done it anyway 2 see if it would come down and it did. then i moved the handel to put it back up and it went up fast and strong but won't come back down agin. my 1950 B works fine up and down. Thanks in advance for any help guys we need it lol.

| I had a CA that did the same thing. I took the pump off three or four times and cleaned it and tried moving the adjustment screws, but nothing helped. Finally, I chained a heavy weight to the lift arm and moved the control level up and down several times and whatever was stuck freed up and the lift worked worked fine. Might be worth a try. |

If ( when) you take the pump apart for cleaning, be sure to do it on a clean bench with lots of light. When one of them itty,bitty check balls pops out, rolls onto your concrete floor... be prepared to spend 2 1/2 HOURS finding it...... yeah....I found out the hard way....sigh... took 3 cleanings for me....

Thanks for the info guys i been wanting to take the pump off but was not sure if i should seeing how the lift went up great. Now that i think of it the guy i bought the tractor from said he lost a little ball that go's in the pump when he had it apart that could be the who problem but if i find 1 missing where should i look to by one from ? Im going to take it apart this week if that don't work then ill try puting a heavy disk on it.
 Thanks agin.. JOSH HODGES |
