TECH MINUTE - Steering Adjustments on Walker Model C, T, and D Eaton M7 Transmissions
Тәжірибелік нұсқаулар және стиль
The following instructions reflect the most current transmission linkage configuration with a spring/ dampener connected to the steering lever (starting S/N 11-109716) and the FSC using direct linkage instead of a sliding fork disconnect (starting S/N 15134121). Earlier units will need to use the transmission control adjustment instructions from the P/N 9000-30 Service Manual.
IMPORTANT: The proper adjustment of the transmission control stops is essential for efficient operation and life of the transmission. These stops are properly adjusted at the factory and should only require readjustment if the transmission or related control linkage is removed or changed.
CAUTION: NEVER attempt to disconnect any safety devices or defeat the purpose of these safety devices.
NOTE: It would not be unusual for a new machine, after initial 5 or 10 hours of operation, to begin to not travel straight (this is due to the break-in of the transmissions). In this case, proceed to Straight Ground Travel Adjustment - Step 4.
IMPORTANT: The following adjustment procedures are sequential. Check and adjust each function in the order given.
Set FSC Travel Limits (Stop) - Step 1:
1. Move the Forward Speed Control (FSC) lever to the most FORWARD position.
2. Check clearance of the RH and LH steering lever actuator arms with the frame and adjust forward stop bolt so each lever clears the frame by at least 1/16 in. (1.6 mm). Clearance of the arm to the frame should be checked while applying pressure back on the arm to remove any slack in the linkage.
3. Tighten the jam nut on the forward travel stop adjusting bolt.
Set Maximum Forward Travel Speed (Stop) - Step 2:
1. Position the FSC lever to the most FORWARD position.
2. Turn the steering lever adjustment nut(s) until 2 or 3 threads are showing past the end of the nut.
3. Loosen the jam nut at the other end of the control rod (where it connects to the transmission control arm).
4. For each steering lever, use a wrench on the adjustment nut, turn the control rod counterclockwise (CCW) until the steering lever begins to move backward, then make two additional turns. Next, reverse and turn the control rod clockwise (CW) until the steering lever stops moving forward and then make one additional turn. Tighten the jam nut.
NOTE: Failure to make at least one extra turn on the control rod can place excessive loads on the transmission internal control stops and cause internal wear and damage to the transmission. Making additional turns beyond one turn reduces the maximum forward travel speed.
Neutral Function Adjustment - Step 3:
1. Securely block the tractor up so the drive tires are off the ground.
2. Move the FSC lever to the NEUTRAL-PARK position (rear travel limit).
3. Start the engine (operate first at idle and then normal operating speeds) and check for movement of the drive wheels.
NOTE: If the engine will not start, check the operation of the neutral safety switch.
4. If drive wheels are moving, adjust the FSC neutral stop by adjusting the FSC actuator rod (see Neutral Function Adjustment photo). If the drive wheels are moving backward, loosen the jam nut and lengthen the FSC actuator rod by turning the adjustment nut counterclockwise (CCW). If the drive wheels are moving forward, use the opposite clockwise (CW) adjustment.
5. At this point it may not be possible to adjust both wheels stationary since the differential adjust has not been made. (This is covered by the Straight Ground Travel Adjustment - Step 4.) In this case, the neutral adjustment should be made for one wheel stationary and the other moving forward slightly.
6. Check the neutral safety switch for closure and function with the FSC in neutral (the engine will not start when the switch is open).
Straight Ground Travel Adjustment - Step 4:
1. Sit in the seat, start the engine (operate at normal speed), and with the FSC in the NEUTRALPARK position check for forward movement of either drive wheel (if either wheel moves backward, refer back to Neutral Function Adjustment - Step 3 and readjust). Tighten the steering lever adjustment nut on the side of the mower with the wheel moving forward until wheel movement stops.
2. Check for straight ground track on a level surface (with hands off the steering levers). Set the FSC at several different speeds and observe if the mower moves in a straight line (use cement joint or other line on the ground for reference).
3. If travel is not straight, tighten the adjustment nut that is on the same side of the mower as the wheel that is moving too fast, e.g., the mower tracks to the right, indicating the LH wheel is moving too fast, tighten the LH adjustment nut.

Wow I could have used this channel in 2018 when I was still working for a lawn care company.

@@walkermowers no longer work for that company but I still think Walker mowers are the best and wish I had one for mowing my yard. I still enjoy watching you channel. I hope to start my own company some day.
great video. Concise with great camera work.
Just tried to adjust mine on my ‘13 model 770 hours. Everything was great until I went to test ride. It was tracking again, small adjustments were made and at that point when I went to neutral I had one hydro spinning backwards. I have tried to adjust again with no luck. Any help? Is this a hydro issue? Or do I need to try the procedure again?

@@alittlebitofeverything5090 I just adjusted it between tracking and when I go to neutral one starts to try to spin backwards. Probably rebuilding hydros soon. I’m kinda surprised but it’s no big deal. Also have to do a engine rebuild soon due to oil consumption. Low hours, taken care of, but I guess it’s part of buying one 2nd hand. Still love the mower and wouldn’t have it any other way.

@@StephenBrewer89 It's a happy medium between the forward and reverse. I just personally rebuilt a walker I bought 2nd hand. If they are not leaking oil they burn it by blowby from the piston rings and oil scrapper eventually wearing. Find someone who is experienced. The cylinders can be honed and motor rebuilt with new rings. Don't let a dealer tell you it needs a new short block. That's the lazy expensive way. Mine does not burn a drop of oil and it currently has 2600 hours on it.

@@alittlebitofeverything5090 I know that’s the truth! Yeah I’m very seasoned with rebuilding engines. Small engines or auto engines. I fixed a kohler CH23s in a Kubota zero turn, low hours, valve guide came unseated due to a cylinder head over temp, binder the rocker and bent the push tube. Local dealer was gonna charge the owner 1300 for the repair and said that was if they didn’t find anything else. I purchased a new OEM head, all the internals, seal kit, everything I needed for less that 400$. Had the job done in about 4 hours total. Sad the stealerships take such advantage of people.

@@StephenBrewer89 @Stephen Brewer Well nice to chat! Interesting you mentioned the overheating on the 23hp. I have a 2005 CH26 efi Walker and when I got it, it had overheated causing a few issues. The reason it overheated was because the cooling fins on the head and block were packed with grass and debris on the blower side of the mower.

We need a good video on installing the Blower Lockout Kit. The instructions in the kit are nearly useless.

I'm surprised Walker has not answered any questions, especially considering that the machine after taxes is almost $20,000 USD. Wow
My machine is a disaster. Its so jerky and the alignment is terrible. I changed the oil on the hydros and my next job is doing this procedure. If this doesnt work im throwing this junk box out.

@walkermowers I called and left a message. Ive been working on my walker for over a month fixing all these little problems. I changed oil seal on trans axle. Belts, new wheels, i took deck off and welded all the rotted out holes, blades, pulleys etc. I did oil change on hydros, engine, and transaxle and i did an alignment via the link you sent me. Im so dissapointed. If im in neutral, full throttle, and pull the right lever back it goes in a donut backwards but NOT SMOOTH AT ALL. Its like im on a horse rodeo trying to throw me off. The left side no problem nice and smooth. Moving forward is no problem but as soon as i try and turn right it goes crazy even if i touch the lever gently. Left seems to be fine but as soon as i gently let it go to go straight again. It jerks on the right side. Its a mess. So frusterated.
