Aarrrgh! Working on these old tractors can be danged frustrating some times! Like ya'll don't already know that, right?
Okay. I finally got the broken off bolt fixed on the exhaust manifold by having a new bolt welded on - that worked great. I proceeded to start putting the top of the engine back together, i.e. I mounted the exhaust manifold and the intake manifold and put the carb back on. It was really starting to look good. I decided then to remove both heads, clean out the expected carbon buildup (there was some) and re-mount them with new gasklets. Good preventive maintenance. Well, the first 17 bolt heads came out fairly easy. A couple needed some persuasion with heat and PB Blaster, but no big deal. Then I hit the last bolt. Nada. Wouldn't move. Soaked it for days in PB, hit it with heat etc. but still nothing. Then it started to move, or so I thought. Snap. Yep, dang thing broke off. Tried using a come along to remove the stub and IT broke! Soooo, took it to the machine shop. He worked on it for two hours and finally told me he will need to remove the engine so he can put it sideways on his drill to drill it out and tap it. Aarrrgh. Well, most of the attachments are already loose (wiring harness, etc.) so that's what I'm going to do. I figured that would be a good time to take a look at the starter, right? The starter in it right now works okay, but it doesn't look like it's disengaging from the flywheel. Might just be stuck or rusty, not sure at this point.
What would the Forum think about replacing the starter while the engine is out? I've looked at eBay and can get a new starter for $50+ dollars, but the company selling them stated to me the parts "come from overseas". Hmmmm. Do I think that means China? Hmmm.
I read an earlier post about problems with aftermarket starters. What do ya'll think?
