Re: Starter through bolts.

I would suggest removing the bolt and taking it to your local starter/alternator repair/rebuilder and match it up. They should be able to help you. That bolt is part of the starter and probably not avaliable for purchase seprately.

NOSLEEP. Do yourself a big faver. while your at it replacing the bolt..Buy new bolts for the front mounts. I'll bet anything the the through bolt broke because the main bolts were loose, if so they have anlignment notches on them that will wear,couseing improper alingment. there only a few bucks. and you will sleep better with out worry...lol :D

Re: Starter through bolts.

Hello jch7450, Good advice.<br />When I first requested help getting the broken<br />through bolt part number. It was because I had<br />noticed the through bolt broken at the rear bracket<br />to the motor. So I thought I would just replace<br />it. The following day I had a little time on my<br />hands and it was a really Warm day, I decided to<br />puts with the motor and did a compression test<br />on the cylinders. When I had all the plugs out<br />and was turning the motor over to do the test I<br />noticed the engine laboring to turn with no<br />compression. So I had a closer look at the starter<br />and when I checked the starter bolts for tightness<br />the inside bolt was loose and would not tighten.<br />I backed it out and found the bolt broken at the<br />start of the threads. Fortunately I was able to get<br />the remainder of the bolt out because it was visible<br />through the top of bolt hole along the back of the<br />block. Boy was I relieved. :cool: <br />If it would of been the far outside bolt their<br />could have been a real problem removing the broken<br />remains. I likely would of needed to remove the motor<br />and turn it over to get at the bolt.<br />I do wounder why it broke? Perhaps it had been<br />previously over tightened and snapped. Or maybe<br />their is some other reason you might know.

Re: Starter through bolts.

I just reread your post jch7450. I wouldn't of<br />thought just being loose would break the bolt.
