A couple days ago, my beloved 1994 LX178 nearly died. I had just finished mowing about an acre and as I was putting her in the garage, I was getting noises from underneath. She limped into the garage. I pulled the deck and checked out the drive train to the hydrostat. I had replaced the belt with a good kevlar last year and replace both idlers at the same time. It really quieted down. Now the belt looked great but the smaller idler was missing the upper side of the pulley! I don't know how that happened, but I had saved the old pulley and put it back on.
Then I went to back out of the garage and it barely moved. I pushed it back in place and checked the fluid level. It looked good. The next thing I did was pull the seat and fenders to get a closer look. When I pulled the fuel tank, the reservoir for the transmission fluid fell off! As I inspected that plastic reservoir, apparently it had loosened up from the rubber hose it was clamped to. The inside of the reservoir was discolored which made it appear to have the proper amount of fluid in it. Now, with the top of the hydro fully exposed, I cleaned the hydro (It wasn't terribly dirty), paying close attention to the hose that the reservoir was mounted on. Not to get any dirt into the hydro! I very thoroughly cleaned the reservoir with carb cleaner and a rag powered by a screwdriver!
I've been running 10-30 full synthetic Valvoline in the hydro, so went to my other building that houses all the fluids and brought over the oil and small funnel. the hydro took 2 full quarts to top it off! That only leaves 1 1/2 quarts in it! Good grief.......did I kill the transmission??? I reinstalled the reservoir and filled it to the proper level. Then I jacked up the rear end and purged the system. Well, the wheels are turning, but how will it do under load??
I put the fenders and seat back on and gently depressed the reverse pedal and nothing happened until I had the pedal down nearly to the fender. But, it did back out of the garage. I was on flat land and started going ten feet forward and ten feet backward. I repeated this several times and the pedals became more responsive. I then took her up an incline and she did well.
The next task I put her through was about a 1/4 mile drive and then back into the garage. The reservoir was down about 2 ounces so I topped it off. Now, I'm checking the fluid level morning and evening whether I use the mower or not. So far, so good. That's one tuff tufftorq!
