I have a 95 k1500 with starter problems. It started out as breaking the outside bolt all the time. We drilled all the way through the block and nutted both sides. It held for a couple years. A few months ago it broke the inside bolt. Replaced it with a new one. Now I'm having problems with them staying tight. The past few days they've been tight but somehow the starter is coming out of place just enough I have to loosen the bolts pull down on it as far as I can tighten them back up then start it. All it does when I try to start it now is grind. I'm guessing the teeth are worn and I need a new starter but I think there's another problem underlying somewhere. Thanks for any help.

I have no help about the starter issue but i did want to add some information about the Nyloc nuts and melting points (they can melt only at 250+ farenheit), i believe they were developed for use in US Aircraft and although the quoted info below is for zytel (a form of nylon) nyloc nuts, the same information applies to both regular and zytel 103 nyloc nuts (one or the other is specified if necessary):

THERMAL PROPERTIES Most nylon insert locknuts are manufactured from Zytel 101 which has an effective temperature range up to 250 ° F. Zytel 103 has a higher effective range to 350 ° F and can be special ordered for your higher heat applications. The insert is available in a wide range of colors: white, green, yellow, red, orange, purple and blue to name a few. The coloring does not add or take away from the performance and is mainly used to identify the manufacturer. Nylon is the most resistant thermo-=plastic resin today. As temperatures increase, it will retain resistance to softening until the maximum degree is reached at which point it melts immediately. On the other hand, with a decrease in temperature, the tensile strength increases and it will have excellent flexibility allowing locking action to continue even in sub-zero temperatures.

CHEMICAL RESISTANCE Nylon is highly resistant to many oils, diluted mineral oils, organic acids, alkalies, solvents and salt solutions. A list of these are available from your salesperson.

ELASTIC RECOVERY Nylon will try to return to its original shape after the mating thread has been removed therefore the nut can be reused many times. The exact reusability depends on thread roughness, minimum breakaway torque acceptability and other factors.
