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.

      Mule Pro MX question:  Is there a trick to removing the center floor panel or "tunnel" other than removing the 8 plastic rivets?  I removed the rivets but the panel won't pop up easily, and I don't want to force it with a crow bar so as not to break some tabs or other hidden parts.  Accessory mount instruction attached.  Thanks for your help.  rider

      Please help, About to buy a new 2020 mule 700 MX. For driving back to my cottage which is only accessible by a 5 km off-road trail. My parents currently have a 2010 teyrx which does the job for a joke. The trail is fairly smooth -1 big rock Rock section that you have to climb. A big  rtv 1100 Kabota does it no problem as well. 
      I am looking into the mule because of its bench seat. One of my dogs cannot run in front because they’ve had a hip replacement. she also has anxiety and is not fare well on the teyrx. We think mainly because she can’t get comfortable because of the centre consul. We were thinking because of the mules bench seat she would be able to sit comfortably between me and my wife.
      my concern is the mules off-road capability. Do they fare pretty well in the woods/decently smooth ride?
      I also plan to do yardwork and plough my driveway with this mule MX. I love the size of it as well, Because it will be easy to store in my shed plus tow behind in my SUV.
      please let me know what it’s like in the woods/snow (in Nova Scotia we mainly only have 5inchs Of snow fall on the ground at a time)
      please help, me with Determining its off-road capabilities. determining it’s off-road capabilities and keep In mind the trail is in good condition. Also my 700 Yamaha raptor, and 400ex use to do the trail amazing. To give an idea that the trail of pretty good.

      I have a brand new Kawasaki Mule 4010 4x4 trans.  While driving it has a vibration/rattle coming from the box area that I can't seem to locate.  I've gone over the vehicle and all the connections associated with converting the vehicle from single to two bench are securely latched.  The tail gate is firmly latched and I don't notice any lose bolts.  Looking for clues to what is vibrating causing the rattle and how to correct.

      Just purchased a 2020 Pro DX  with Yanmar diesel. Had a 2007  3010 Trans Diesel I traded in. My problem is that the new machine is so much noisier  than my old one.
      Has anyone had any luck in quieting down the noise? Sound proofing.?...changing the exhaust routing.?...the muffler? Any ideas or solutions would be appreciated.
