The idler shaft can now be removed. Remove thrust plate and shims from opposite hub of idler wheel. Refer to paragraph for dimensional specifications of shafts and bushings and proceed as follows: Inspect bushings (16) in front idler for excessive scoring and wear and if renewal is required, press out old bushing using John Deere tool number Fig. 31 - View of tension bolt lock nut and adjusting nut on 40C models. serio I number 6.64 and up. 40C and 430C models are similar except that tension bolt is reversed.

Remove stop valve (7) and bleed valve (5) by pushing stop rod (1) completely into cylinder. Withdraw stop valve from bleed valve, being careful not to lose the small ball (3). Remove nut from pis (on rod, being careful not to distort the rod, and remove piston and rod. Push stop rod (1) all the way into cylinder and drift our Groov pin (19). Remove piston rod guide (7). Examine all parts for being excessively worn and renew all seals. Wiper seal (30) should be installed with sealing lip toward outer end of bore. Install stop rod ("V" seal assembly) (0, 1, & 6) with sealing edge toward cylinder. Complete the assembly by reversing the disassembly procedure and tighten the end cap bolts to a torque of 85 Ft.-Lbs. Install the piston rod stop as outlined in paragraph 55. 83. OVERRIDE CONVERSION. Hydraulic stop type remote cylinders can be adjusted to provide a maximum working stroke of 8 inches. rmally, the stop can be located so 6% inches of stroke is obtained and then an additional 1% inches of slow movement is obtained by means of the "override" feature. If, in some applications, the override feature is found to be undesir "ble, the cylinder can be converted to a non-override cylinder by removing the AA5731R stop valve and installing an A595R valve. To do so, remove the cylinder end cap (11-Fig. 361) and withdraw spring (8) and valve (7). Be careful not to lose ball (3). Install new stop valve A595R, old spring (8) and cylinder cap. Tighten the end cap bolts to a torque of 85 Ft.-Lbs. Check sealing of new valve as follows: Apply pressure to cylinder rod and check for piston movement as the stop is released. If a positive stop is not reached, remove cylinder cap and lap the valve to its seat until a pei"fect seal is obtained.
