Steering was slipping gears. Disassembled unit and removed steering shaft. Bushings are shot and pinion gear is moving away from sector gear causing the skipping. The parts catalog calls for 4 M114891 bushings. I only found one at the bottom of the housing where the pinion gear is. The diagram does not show that one however it does show one at the top of the aluminum housing where the steering wheel shaft enters the housing. I think there should be two on the steering shaft (top and bottom) and two on the sector gear shaft (top and bottom). Please help me out here -- how many and where do they go. Thanks in advance.

The "T-bolt", as referred to in the Yard Machine's Operator's guide, is a plastic top with a wide diameter on top of a skinny threaded metal bolt. When you put the bolt through the bracket and then through the hole in the mower handle, the bracket has an area towards the top where only the threaded portion can through and the plastic top with the wider diameter cannot. Then at the bottom, hard to see and photograph, there is no area for the screw to screw into though the operators guide says to "screw in the T-bolt". The mower is usable without this T-bolt slid in (but not screwed in) but I can't help but think something's missing
