I have a 1310 that I am rebuilding. I have replaced gears in one gearbox and cleaned the others. I'm half complete with replacing all seals on the mower. NAPA, Alamo (Servis-Rhino parent), and a local gear store are good for seals. The gears have a keyway. The spindles are not splined. These gears are pressed in. The gearbox housing is sandwiched between a gear and a bearing. I'm looking for a tool to tighten the locking nuts (I have new ones.) on the spindles. The "time honored" way of tightening them has destroyed the old ones. Does anyone know where to get this tool? Your post was fairly old when I saw it, but I can tell you what my manual says about timing. The operator's manual, the third edition, was printed 5-15-73 for the Gyro-1310. Blade Timing and Rotation "The Blade Carriers are timed at factory by a method you too can follow if field repair work is necessary and re-timing required. FIRST, by means of a hoist fastened to front of cutter, raise the cutter frame to a secure vertical position. (It will be of advantage to disconnect the axle, etc., and let rear of cutter frame rest on ground for stability). With cutter thus upright and viewing the under side, align the Blade Carriers in relative position so as to resemble the letter "H". This may be done by aligning the carriers, by sight, with the several underneath, Frame-Cross Members. SECOND, walk around to opposite (Top) side of cutter frame and note the relative positions of the Flexible Coupling Spider Yokes of Gear Boxes. Hold up the Flexible Coupling Drive Line and compare its bolt locations with holes in Gear Box Spider Yokes. If necessary to adjust for fit, slip the Spline Shaft out of Splined Housing, rotate as required, re-engage and bolt in place. SUGGESTION: Fasten Right Hand Flexible Drive Line in position first. Follow the same procedure for the Left Hand Drive Line. NOTE: If perfect 90-degree relationship of Blade Carriers cannot be obtained, adjust the Drive Line one notch, so that the Left Hand Carrier will lead slightly in direction of rotation." The only diagram is the top view of the mower. I'll try to describe it. As the mower is hooked to the tractor, viewing from behind the mower, the left blade carrier will be on your left. It has counter-clockwise rotation. The center blade carrier also has counter-clockwise rotation. The right blade carrier has clockwise rotation. I hope this can be of help to someone else if you have already figured it out. I have not timed my blade carriers yet, but I think I can do it without the hoist. I have a question: You should have a Morse Torque Limiter 700A on your Servis 1310. Do you know if it is the 700A-1 or the 700A-2? Morse described the 700A-2 as being the same as the 700A-1 except for an extra disk spring on the -2. My limiter has the stamping "Morse Torque Limiter 700 A" on the hub, but anything else is obscured by the years of use it has seen. It does have an extra disk spring, but my limiter may have been modified. I'm trying to get the right one so it lasts another 30(?) years. Thanks for any information you might have.
