99 kawasaki mule 550 Valve guides

Recommended Posts

Greetings all

 I have a 99 kawasaki mule 550  kaf300c3 That I ordered new valve guides for. Problem is my valves don't fit in new valve guides. Part number is correct. 

 Is it possible that valve guides need to be installed and reamed before the valves will fit into the  guides?   Just seems like an awful lot of material to have to remove by reaming.

Thanks for any help

Yes, they will need to be installed and reamed by a machinist. Or Kawasaki did sell a special tool for guide reaming, P/N 57001-162 but good luck finding it. might could ask a local Kawasaki dealer. I remember back when i did my mule, one of the valve guides (exhaust i think) moved in the head, so went ahead and bought 2 new guides, the machinist didn't have the right reamer, so they measured the I.D. and found it within spec so they just pressed the guide back down, it's stayed so far.

What's wrong with yours?

The  Engine was burning a lot of oil so I decided to put new rings and valve seals in.   The Valves  Had a lot  of slop in them so decided to change them too since I had it apart anyway

might try measuring the O.D. of the valve stem , might could compensate for some wear with new valves. But of course if the guide bore I.D. is too large then that won't work.

      We have a new Mule Pro FX LE EPS.  It has the manual dump bed and looking to add some type of electric lift to it.  Even with a small load, two people can't dump it by hand.  Seems kind of a bad design, hinge point and the hydraulic strut assist is too far towards the back.  Been looking at electric actuators on ebay.  For those that have done this, do you put the actuator in place of the strut?  How does it work?  To me, I would think even with a 400lb actuator, it might struggle since it would be so far back.  Thinking of putting it towards the front more.  But not sure of the best place to mount it.  And would I need a super long stroke to get it to raise the bed all the way?

      2007 Mule 610,  owned for 8 yrs and valves were ticking when I got it and had them adjusted twice and this is when plugs began to foul.  I replaced battery (used battery I had on hand) a yr ago and didn't foul a plug for some time and replaced batter (new) with a bigger lawn mower type battery again a month ago and have fouled two plug since.  Had carb cleaned and valves adjusted and still fouls plugs way to often.  Friend has a mule just like mine and his does same thing. Have read this is a common problem with 610 mule.  Any help or suggestions would be welcomed.  Thanks and stay healthy.

      This file contains all specifications,troubleshooting and repair procedures for the FE290D  (9.5H.P,286cc) engine used in the  Mule 500,520 and 550 models.

      Make sure you're reading the correct information as this manual covers multiple FE series engine, some of which were not used in Mules, the manual does a very good job of clarifying which specifications and procedures are for which Model engine.
