Unique starter problem

My first post on the form here hopefully someone can steer me in the right direction. My truck is a 2000 crew cab 7.3 and I’m having problems with my starter. I build a hybrid starter taking the nose cone from the 7.3 and mating it to a 6.7 gear reduction starter. The starters are stupid simple to build and nose cone and gear protrusion when activated are identical.

The truck started fine for a while but when it has gotten cold I have problems. Truck spins and starts amazing, but the starter is staying partially engaged only when it’s cold. Just a chirp from the flywheel contacting the starter gear. It has to be below 30 and first start of the day(cold engine) Anytime after that fires up perfect. Also if the truck is plugged in I have no problems which is strange being it’s cold weather dependent.

So far I took the starter back out and rebuilt it inspecting it and added extra lube to some places. Replaced the started solenoid on the fender. I have auto start on the truck and it does it with or without using it. This let me exclude a sticky ignition not letting the key return to run position. I Tested the ignition wire at the fender for power being fed after start up and had no power. I’ve also jumped the fender relay and the problem still existed. The only electronics I haven’t replaced are the ignition switch in the steering column and solenoid on the starter it’s self. The starter was put in November of 19.

My last ditch thoughts before junking the starter is to double check the solenoid trigger wire on the starter for power after start up. I’m just confused why temperature is causing this problem. Also I’m going to use a blow dryer and heat just the starter up slightly to see if that makes a difference. If not it’s getting pulled and a denso will go in. If anyone can help I’d be super appreciative

Checking voltage on the solenoid power wire is a good idea -- soon as you release the key the power should stop

I have seen solenoid cores bind up in cold weather -- did you pull the core and clean it off? (and bore)?
also any grease on the sliding parts needs to be light enough to not bind up in cold weather

For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.

I didn’t add too much grease just a touch here and there. I never pulled the solenoid from the starter itself. It functioned fine when I inspected it but I was in a warm shop.

I’m thinking if I warm the solenoid it would be a quick way to determine or rule out the starter being the problem.

Easy enough to pull the solenoid and clean the plunger
was the starter new or used?
def sounds like binding of the engage mechanism

tho don't rule out back feed or a ground loop situation
adding a light to the solenoid trigger wire would let you know if power dropped immediately or just tapered off

A nice brisk 19 this morning. Climbed under the truck with my test light and used both the auto start and my girlfriend assistant to start the truck. Both times the trigger wire to the starter cut power immediately with the starter shutting off and the starter chirp was there. Grabbed the heat gun and warmed the starter to lukewarm fired her up and no starter chirping.

By "chirp" are you talking about the gears grinding or a dry motor bearing? Entirely different sounds

A vid would be nice

It’s noise from the starter gear grinding on the flex plate. I don’t have one now but I might be able to take one tomorrow morning
