The center-to-center spacing between the engine shaft and the jackshaft (i.e. spacing between the dead centers of the two bolt holes that will secure the two Comet pulleys) must be exact for a particular belt. The jackshaft will extend out farther than the Vanguard shaft so here is the most accurate way to measure the spacing: Put an accurate ruler against the back side of the Vanguard engine shaft and let it extend straight past the end of the jackshaft shaft. Then eyeball as accurately as possible to the exact center of the jackshaft and take the measurement. The Vanguard shaft is 1 inch in diameter, so add 1/2 inch to the measurement to get the true distance between the centers of the two shafts. It is hard to design and built a system and have the spacing come out exact, so some means of minor adjustment is helpful. Once this spacing is attained no further adjustment is ever made. The belt will appear extremely loose, but it will tightens up as the driver pulley increases RPM.

How do you change a drive-belt on an STX38 John Deere lawnmower?
Changing a JD STX38 transmission drive belt.Today I undertook removing my almost failed transmission drive belt on a John Deere STX38. In order to do so (it had come off both the engine pulley and the transmission pulley but was not broken), I had to unbolt the brake pedal lock pin, and disconnect the front wheel steering bars (cotter pin and washer holding each bar to the front wheel axels). The belt then could be removed as the steering arms pass under the belt when it is in place, and the bars are attached by cotter pin and washer, one set at the wheels, and another set at the steering arms in the middle of the chassis. There is one idler pulley in a v shape and another idler pulley that is flattened between the transmission and the steering arms. The back of the belt pushes against the flattened pulley, and the inside (v side) of the belt passes the v shaped pulley as these 2 pulleys provide belt tension.
