Thr jerking is a normal reaction.Thats the way they worked. It wasn't a smooth operating system. The steering is all mechanical . There is a tin cover on top of each steering clutch housing under the seat [ I think 5 3/8 inch bolts on each cover ] With the covers off , you can watch the movement of the linkage..The long 3/8" bolt is the free-play adjustment . Excluding any slop in the linkage, the lever should have about an inch of free-play like any other clutch. Then the throw-out bearing begins to disengage the clutch . After there is some slippage in the clutch, then the brake band clamps around the exterior of the clutch drum causing the track to stop thus steering the machine..Now that we understand the operation of this now's the time to troubleshoot it..In many cases I've seen the clutches wet causing rusting of the clutch disks and plates insude the clutch drum..These machines should always be covered with a tarp from the dashboard over the top of fuel tank to keep water / snow from sitting on top of steering covers..Water can and will get inside through lever bushings and top covers..Inside the top covers you will notice a shorter 5/16" bolt. This is the brake timing bolt. One knuckle there should be Keyed to the shaft and the other knuckle should turn on the shaft.Many times the knuckles are rusted tight and won't operate right.Also in there you will find a 13/16" bolt head standing upright , this is the brake band adjustment. As far as the HLR transmission goes..With the machine off , Listen to the HLR shift detents . There should be a definite click as it shifts into each gear range.If reverse doesn't have this click , look for loose shifter linkage or clevis adjustment that will allow the transmission to shift into full range. I have had to relieve the shifter quadrant with a file to allow the shifter lever to go further than it is supposed to go..If it does click fully into reverse , there might be a pressure problem with the transmission. Look into archives for HLR adjustments..I know I've got a bunch of solutions along with my other learned colliegues there.. good luck
