Looking for info on the hydraulic cylinder that runs the bucket or any other attachment of a 632. The assembly that is there is not original and does not allow the bucket to dump at or greater than 90 degrees. Meaning that the reach of the piston needs another inch to get to vertical so it will dump from lowest to highest height extension of the loader arms. The one on there now is 19 inches from pin centre to pin centre and is 3 inches in diameter with a 1 1/2 inch diameter ram or piston that reaches out ??? because I did not take that measurement :( In attempting to fix this problem a total assembly was installed from an older 743 but the housing of the piston is too long and does not allow the piston to retract enough to get the bucket flat/horizontal. Between the two installs we have deduced that the assembly required would be a 3 1/2 in bore with a 20 " length retracted ( centre to centre ) and 12 inch ram reach with overall extended length of 32 to 32 1/2 to allow the bucket to function properly. Can anyone verify these measurements ? I am looking at buying a hydraulic utility cylinder from Princess Auto with the above measurements as a stock unit and a friend is going to match the 1 1/4 inch pin holes with fabricated brackets attached to the new cylinder housing and ram because the new ones are only 1 inch. Another option is to buy one with a 24 inch housing and 16 inch reach and mess around with cutting it to perfect performance size. This will run about $250 with taxes included instead of about $1500 from the dealer for replacement part. Any input would be helpful.
