Oreilly Reman Starter Woes

AlaskanRider · Mar 5, 2013

Hello,
My '76 3/4 ton highboy will crank real real slow when its hot, but great when its cold. Starter is a couple weeks old, battery is about a month old. Its so slow to crank that it will only start about half the time, and super easy to flood.

I put my hand on the starter, and it gets really hot while running, just from being close to the exhaust.

I've found if i start chucking snowballs at the starter through the gap in the fender mud guard right after I shut it off, it helps tremendously. This is a fine solution for me, but the snow will melt here in a few months, and then im a little screwed if i ever need to hot start it.

So I'm wondering if I should trade it out for a new starter or try to improvise some heat shielding from the exhaust. Anyone else had issues like this? Bad reman?

You might try and wrap some heat wrap on the exhaust where the starter is or make some kind of heat shield to protect the starter from the heat of the exhaust

Sent from, wait how did this get here?

As well as wrapping the exhaust and building a shield I would check the wiring. After that many years current draw and heat could have fubar'd the wiring.

Especially the heavy cable.

I hadn't thought of that. The cable gets snow on it too when i hit the starter, will check.

This would be my guess too.

i would do an amp draw test on the complete system, both when hot and cold, then at the starter itself. make sure you have good cables, and good grounds. i have had a couple of defective reman starters, and even on a new starter

Many Times, the "Field Coils" (the ones in the case), will get "thermal", What I mean is that as they warm up, the internal insulation IN the coils breaks down, and does NOT act correctly (they suck current, BUT do NOT produce the needed "Kick" to spin the armature), once cool again, they are "good to go again" until warm again.

IN the old days one could remove and RE-Wrap them, BUT with the cheapness of starters today, get it warranty replaced, as the field coils are "internally Shorted" when warm.

Thanks, ill probably do that. I talked to some other FE owners and they said that they dont have issues like this. My manifolds warp all the time, and need as much cooling as they can get.

Wires are brand new, and clean connections. I think oreilly just sold me a junk starter.

Are you running too lean?

Check and double check that you have a proper ground from engine to frame and that your battery cable is probably grounded and making perfect contact. I would also double check teh battery, even though you say it is new. Check your charging system to see if the battery is being kept charged.

Is the timing advanced ?
