I have a Kawasaki FH580V on my Scag Freedom Z. Recently replaced the governor shaft seal along with several other items (nothing with the carb). Starts up and seems to run fine while cool. After mowing a while the engine speeds up "considerably" when I disengage the blades. Even when the...

I recently performed significant work on my 17 year old mower (significant for me). Replaced: starter, breather plate and gasket, upper crankshaft seal, governer shaft seal, clutch, both transaxle filters, refilled with 20-50w oil, fuel filter, engine filter and 10-30w oil. I completed the...

After replacing the upper shaft seal and breather plate and gasket I thoroughly cleaned the oily mess. After mowing a couple of hours I can see a new oily mess from what appears to be a leak at the governor shaft seal. After watching a couple of YouTube videos it doesn't appear to be a...

I've removed the two filters and drained all fluid from both sides. Installed new filters. I'm unable to remove either top port plug. I've applied penetrating oil a couple of times and will allow it to (hopefully) work overnight. These plugs require 1/4" hex key, not a socket wrench. I...

A couple of years ago advice from this forum helped me set the air gap on my Ogura clutch on my Freedom Z. Everything seemed fine until recently when I started hearing a loud "scraping" sound seemingly coming from the clutch when the blades are disengaged. No unusual sound when engaged. I...

I found some bolt torque specs for this engine on the web, but not specifically for the breather cover. Can someone provide me with that torque? Thanks

This topic came up after I started a thread about my starter on this engine. Seemed like a new thread is in order: One or more significant oil leaks have existed for sometime causing quite a mess on the entire upper engine (mostly hidden by the engine cover). Txmowman pointed to the breather...

Any tips as to how I should attempt to remove the flywheel from my Kawasaki FH580v? As you can see in the photo it is held on by bolt, not by nut and there are no holes to attach a wheel puller. I've watched several videos, but none seem to apply to this engine. I'm trying to access the...

I have a Scag mower with a FH580V Kawasaki engine. It appears that the gear on the starter shaft has come loose from the shaft. When energized the starter gear rises to engage the flywheel. The starter shaft spins at a high speed, but the gear doesn't move. Is this a DIY repairable situation...

The battery on my Scag Freedom Z isn't charging. It has a Kawasaki FH580V. My initial diagnosis a few days ago indicated the rectifier was bad. The AC voltage from the stator was over 24V (and still is). I read only battery voltage between the rectifier terminal going to the battery, not 14...

I recently ordered a set of three blades from Amazon for my Scag Freedom Z 52". The new blades are the same length as authentic Scag blades and appear to be the same thickness and weight. However, in the attached photo you'll see that the cutting edges are somewhat longer and the "notches" are...

I recently had to replace the main drive belt (between engine and the two drive axles). Having never changed this belt, I first thought I'd need to remove the main pulley/clutch assembly. I soon realized that wasn't necessary, but I "discovered" what I thought were loose nuts on the clutch...

Can anyone direct me to an online electrical schematic for my 14 year old Freedom Z with 19 HP Kawasaki? I'm hoping to find a real schematic, not just the diagram included in the owner's manual. A schematic will show the inner "workings" of each electrical component (e.g. contacts, coils etc.)...

The mower is 12 years old with 1200 hours. I took the mower to a repair shop due to a leaking seal on the left transaxle. Also the left steering control arm had recently started rapidly returning to neutral in a very quick almost jerky movement. This arm now requires very little force to move...

I have a Scag Freedom Z with a Kawasaki FH580V-AW00 that is 14 years old with less than 700 hours. I've changed the oil and filter regularly and run only non-ethanol 87 octane. Never had any problems until now. Recently it wouldn't start and seemed the cranking speed was slower than in the...
