10 hour service on 2550

[JSharp]

Hey guys, not to hijack the thread, but I saw the comment about a steering recall. I have a 2005 GT 2550 and never received anything about a steering recall. Does anyone have any detail on the recall?

Thanks.

The early '06 2554 models had a recall to add an additional zerk on the steering shaft lower bushing right above the pinion gear and possibly some other steering work. My dealer had mine one day and it came back with the new zerk but I couldn't tell what else had been done if anything. I don't know if other models were effected...

Thanks, I will check with dealer.

I just finished the 10 hour service on my 2544. I found I was missing one lug nut, and one of the deck wash connections is missing. Also I'm not sure where the front axle pivot bolt is, I can't find a grease fitting for it. Other than that all went well . I had a problem with the engine coughing when I shut down but
*93 octane seems to take care of that.

*Reving the motor up then cutting the switch will cure it a lot cheaper.
My 2554 burns enough $3.09 #89 with out going to the more expensive # 93!

Front axle pivot bolt is underneath the junction where the two front axles come together. It is hidden from sight unless you get underneath the tractor.

Why are you using 89? 87 octane will work fine. The engine is not high enough compression ratio to require anything higher. My antique 1958 Harley gets 35 mpg on regular gas and drops to 33 with premium. I tested it enough to verify that it wasn't just a fluke. Higher octane fuel burns more slowly to prevent detonation. On a low compression engine the fuel may not be completely burned at the end of the power stroke so part of the energy is wasted.

For me, I also use 89 octane. When fuel sits, the Octane rating will eventually drop with age. So by going with a couple point higher fuel, I help to prevent this problem. My leaf blower indicates that it requires 89 octane or higher. Having fuel on hand that I could run in all equipment is a plus also. I have a larger fuel container that I pour fuel off of to mix my 2 cycle mixes for the smaller tools.

I don't use 89 .
I use 87.
89 was a Typo.

I think high octane can also be hard on the valves, too.

89 is a weird blend of fuel. I don't think they raise the octane in that by usual means. I think they use alchohol or some other additive.

Here in Illinois it's virtually impossible to find fuel without alcohol...

89 octane gas is a mixture of regular unleaded (87 octane) and premium unleaded (91-93 octane, depending on brand). Some gas stations only have two tanks - one for regular, one for premium - and utilize blender pumps to dispense 89 octane mid-grade. These pumps use to be able to identified by only having one nozzle for all grades. Now some of the newer pumps only have one nozzle even though the station may have separate tanks for each grade of gas.

As for the alcohol in gasoline, ethanol is being used as the replacement for MTBE (Methyl tert-butyl ether) which was used to oxygenate gas, but now is being phased out due to concerns of it contaminating drinking water.
