CH 18 head gasket

Probably....

But I've never done it.  Mine is out right now awaiting the heads to come back from an engine machine shop.  The old head gasket kit used to come with new head gaskets but the new one doesn't.  Also, When you pull your valve covers, check for cracking around the bolt holes, even if they have the metal inserts.  I just bought two new ones & the one with the oil fill is cheaper than the one without so mine will have two with the oil fill.  This will be the third style I've seen.  Now they have a relief cut on the corners as well as the inserts.  Now idea why.  There are three different gaskets for those depending on what style you have & every single type leaks if you don't add sealer.  Another reason to pull the engine is to perform a thorough cleaning. 

Sorry guys.  I know most rave about this engine but I think it crap.  Third set of leaking valve covers, Second valve job, Three coils, & now potentially a new flywheel as three magnets are loose. 

This thing is absolutely NO better than a Triad!

Difficult (i.e. impossible) to replace heads without removing shroud.  The intake  manifold must (at least) be unbolted from the heads to replace the heads.  That manifold is under the shroud.  There is no room to get the shroud off without removing the engine.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
