Cylinder Head Bolts

Recommended Posts

Hey, how important is it to buy new head bolts when rebuilding an engine? My brother who has rebuilt several big and small engines says it's important, some say it's an option, If you have the money, do it, If you don't, don't.

01 Kawasaki Mule 550 C5.

Over torqued bolts can stretch. The next step is to break. When they break, they're nearly impossible to extract. I doubt that You'll have any trouble, but it's your call. I personally, wouldn't worry about it. But I'd be very careful when tightening.

Thanks, Im thinking i'll go with new bolts cause all the new bolts are only like $17.00.

Still need to get that shim on the crankshaft, been REALLY busy lately so i might take to the machine shop and have them take the measurements...

Since there couldn't be much to it, taking that measurement. I would think, that they wouldn't mind measuring that for you. Since you've had them do some other work on this same engine. 

   I'd suggest that you take it with you, and visit the shop. Talk to the guy that you talked to before, about the casting defect/crack. And ask how you'd go about measuring for that shim. Tell him what you don't understand about the procedure. Or that you don't have the tool, whatever. Maybe offer him ten bucks.

  My guess would be that you'd just use a feeler gauge. Making sure that the crank is pulled forward, if it has any play, front to rear. But I've never dealt with that, and without seeing it in person, I can only guess.

      Hi, all, I am here to say i have found an excellent source for kawasaki parts, It's run by  Eddie Babbit. It is called Kawasaki Partshouse. run by Babbits online, Muskegon Michigan. http://www.kawasakipartshouse.com/oemparts
      Just the other day i ordered piston rings, for my Mule 550, They got here and a Oil ring, and smaller ring were missing from the box, Kawasaki took responsibility for the "Accident" and  I had also contacted babbits, and they replied and they said" keep the old rings, order a new set and you just pay shipping" so i got $30 piston rings for 8.95!!!? Free shipping on orders over $50!!!

      Hi, I think I just bought a Husun 450 that is in need of TLC. It is leaking badly from the shifter shaft (located at left foot). I can not find a part number for the seal(s) 3 came off of the shaft.
       
      If anyone can help I would be extremely grateful 🙏

      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.
