    Bearing preload

    I need to replace the castor bearings on my Classic. Anybody have an idea what the torque is for the bearing preload? Is it like the old car front bearings where you tighten to 10 lbft, loosen then turn it finger tight?

    Kohler ECV870 misfiring

    Sorry it's taken so long to respond. Finally received the O2 sensor and got it installed. It appears that is the solution as there is no loss of power and no misfire when engine warmed up and deck engaged. Thank-you everyone for all the suggestions and patience with me. You folks saved me a...

    Kohler ECV870 misfiring

    Yes, it was misfiring as you can see from the rpm display. Typically it would idle 1500-1550 rpm but as the video shows it dropped to the 1300's, and when the deck is engaged with the mower setting still it typically runs between 3300-3400 rpm but with the o2 connected it was dropping down to...

    Kohler ECV870 misfiring

    Okay, got the o2 sensor plugged back in and the ecu reset, fired it up ran good for 6-7 minutes then started misfiring. Hooked up my light to check for codes and no codes set, just the end message of 61. Also, didn't get a chance to do the tps learn procedure due to the misfiring.

    Kohler ECV870 misfiring

    Okay, finally got my test light set up, I have codes 0032 and 0132 set in the ecu. With key on and engine not running, I have 11.7v on pin A of O2 connector (red+black wire), 0v on pin B (green wire), 3.4v on pin C (violet wire), and 0v on pin D (black wire). Resistance between pin D and the...

    Kohler ECV870 misfiring

    I ran it for about 2.5 hours today with the O2 sensor disconnected. It seemed to run about normal, 3400 rpm with desk engaged, no load; 3320-3180 while cutting grass. Actual no rpm is around 4300, I've always thought that was too high, maybe I've been running lean all this time. I bought the...

    Kohler ECV870 misfiring

    Yes, I ran it with the O2 sensor disconnected, that was in my previous post. It seemed to run fine with the o2 sensor disconnected. And thank-you for the download link, I'll get that right now. I'll see about getting a small incandescent light tomorrow. I have an old pressure gage but it...

    Kohler ECV870 misfiring

    Tried to hook up my DVM to the MIL output terminal (pins 3 and 4 on 6 wire connector) but it doesn't respond quick enough to capture the voltage change. Ran engine at 2600rpm for 4 minutes, started missing but no black smoke. Disconnected o2 sensor and ran at 2600 for 4 minutes, no miss...

    Kohler ECV870 misfiring

    Unfortunately no MIL light, the engine model number is for the Kohler 31hp fuel injected engine used on Dixie Chopper lawn mowers so there is no choke or carburetor. The primary side was checked from the ECU connector terminals through the coil with a DVM. The coil supports a dual spark plug...

    Kohler ECV870 misfiring

    Have a 2016 Dixie Chopper Classic with a Kohler ECV870-3013 and it has an odd issue. It starts fine and runs good for about 2-3 minutes then gets weak RPM drops from 3300 to 26-2800 and exhaust smells rich. Shut it off, restart it and runs good for 2-3 minutes rinse repeat. Check the primary...

    Just bought a 2016 Chopper Classic, need some advice

    Right, it seems to be operating in reverse of the way it is supposed to. It almost as if the switch was replace with an incorrect one. Normally open when it should be normally closed or vice versa.
