On my '08 MT machine I actually only needed to replace the pulley with the smaller diameter one, this is NOT the pulley on the engine. It's a 5 minute swap. The spring that was included was not needed as the tension on the belt with the old spring was sufficient. I actually couldn't even stretch the new shorter spring to fit, which is why I didn't use it.

So does the speedup kit void the warranty of the hydros? I have an 08 MT and my left side hydro quit today, still works a little bit but not as strong as the other and it chatters in reverse. Any advice appreciated thanks

The speed up kit is a Walker part, I'm sure they wouldn't sell an add on for a machine that voids the warranty. If you are under 1,000 hours, and your hydro resivour cups are still sealed, they should be covered still.

AFTER u have fitted the factory speed up kit
[make sure u have the upgraded kit not the ealier version ]
[later kit gives better belt wrap = less slip ]

MOST IMPORTANT IS TO

FIT HEAVY DUTY SPRING GASERS
[jack shaft to engine pulley v belt]
{u can order from walker ,it was included in ealier speed up kits ]

ALSO Fit all upgraded tension arms
Fit upgraded tension arm pivot bearings DU Type

Once all installed all ,u will need is a Tacho

TYPE
photo tacho non contact [infared beam reflects on the reflective tape ]

WHY
Adjust your engine to absoute max of specification 4 your engine
[adjust once engine has reached operating temp ]

Once u have done this as above
CHECK pulley speed that is bolted to hydro

Absolute max 3600rpm Input shaft/pulley speed

The 3600 rpm spec is from the -- ""Eaton Model 7 transmission manual ""--

Eg Md walker all new pulleys belts etc 3540 rpm at hydro with engine adjusted to max specification 3450 rpm at hydro with engine at 3600rpm??? When I used a digital tiny tach, turned out my MDD engine was only adjusted to max 3450?? Am I incorrect? Then with hand gps clocked right around 7mph. Then I backed everything down to a safer 6.5mph. Am I wrong doing this?
