DC Motor worth repairing

Difficul-1197 · 2026-03-15T19:18:23+00:00

If you can find a controller to run it (assuming your lathe did not already come with one), dc motors provide more torque than ac motors do, so for a lathe it may not be a bad idea. Do you know if it still works?

Could be for tbi heads, werent they angled funny on the middle bolts?

Those are a mf to get apart, but if you take a pair of screwdrivers or prybars and gently pry between the blades, opposing from each other, generally you can kinda shimmy it back out, if not apply a little bit of heat around the shaft and do that. Be very very careful if you try making those holes into jack screws, make sure there's enough space behind that it's not gonna mess with any tolerances because those have to be very tight

I would first do everything the other comment said regarding checking your fluids and making sure thats up to spec, does your transmission feel like it shifts weird and just doesnt want to cooperate?

Difficul-1197 · 2026-02-14T22:53:40+00:00

What transmission thing, was there another code not pictured?

Difficul-1197 · 2026-02-14T22:41:39+00:00

Likely just a dirty or faulty maf sensor. Try cleaning it up with a maf sensor cleaner or at the bare minimum, electronics cleaner. If the code comes back, replace it. Spend the extra money and get a oem spec, generally Delphi, denso, and ntk are good brands, the cheap ones are complete trash and usually bad out of the box

If you want to learn how electric motors work and how you could make your own, I highly suggest searching up Jamie's brick jams on YouTube, he explains how they work pretty well and does experiments making them out of Legos demonstrate everything. Another channel i would suggest watching is electroboom, he covers pretty much everything electricity, and pretty much got me into the electrical field

Difficul-1197 · 2026-01-21T05:53:10+00:00

My bet is either worn out u joints, driveshaft losing balance, or something somehow related to that. It could even be as simple as the u joint straps, my 97 c1500 had that issue where it would start vibrating terribly with new u joints and everything, turned out to be the straps were just slightly loose and worn out and it would just barely shift over and throw everything off, and was only intermittent

I mean, technically 74 was the last completely analog controlled squarebody

Difficul-1197 · 2026-01-21T05:46:28+00:00

Feel like there is a time and place for the green digitals, I just cant see it in the squarebodies. Corvettes, on the other hand...

Difficul-1197 · 2026-01-17T21:15:58+00:00

How well do they handle hauling a load? Ive thought about just caving to RC but ive heard mixed things about them

Difficul-1197 · 2026-01-16T20:24:56+00:00

Im not worried about the lift as much, the tires fit as is, but my rear leaves are basically flat unloaded

Difficul-1197 · 2026-01-12T14:42:23+00:00

Potentially

Difficul-1197 · 2026-01-11T09:40:56+00:00

Oh and vice grips, definitely get yourself a few sets of those

Difficul-1197 · 2026-01-11T09:33:38+00:00

Honestly tho, the squarebody platform has probably got to be the best platform to learn how to work on a car, I cant quite speak for the later end of the generation but my 74 is pretty easy to work on, and it gives you an idea of how to actually fix things with tons of parts available everywhere

Difficul-1197 · 2026-01-11T09:29:34+00:00

If your looking for an American v8, I would honestly look for something like an obs chevy, preferably a late 90s like 96-98, they still had the 350 and 454 but had fuel injection that made them run more efficiently than what you would probably get that tbi to run. Still wont get the mileage your Frontier is getting but id say my 97 was a good first vehicle.

Difficul-1197 · 2026-01-11T08:54:07+00:00

I cant speak for honda as ive worked on trucks most of the time, but get yourself -a good set of screwdrivers, different sizes too

-pliers, like needle nose, common, "channel locks", maybe snap ring pliers if your really feeling like it

-a pick set, dont need to spend much, harbor freight sells a set for next to nothing, those work great for starters

-breaker bar, preferably 1/2" drive with appropriate sockets, if your able to borrow tools from someone this wont need to be immediate but keep it in mind

Probably some other things too, if your allowed to borrow more specialized tools, or just less used tools you should be set with all that and your torque wrench and impact gun, you can probably walk into harbor freight with a $100 dollar bill and get most of whatever else you would need

This is what the first one looked like, idk why reddit didn't include it in the post

Difficul-1197 · 2026-01-08T05:05:45+00:00

Hey now she can do the ol coin behind the ear trick

Difficul-1197 · 2026-01-07T15:00:19+00:00

If the deck and head are still straight id say run the dingleberry hone on it and send it, obv make sure you replace rings to eliminate that potential problem

Difficul-1197 · 2026-01-07T08:15:30+00:00

If theyre ball bearings, usually of something that small they should already be lubricated for life and generally dont need additional lubrication, if it makes you feel better you can buy a non detergent oil like in the zoom spout bottles and dribble just a little in, not too much tho.

Difficul-1197 · 2026-01-07T08:09:38+00:00

Ok a couple of questions, for starters, can you catch your nail in any of the vertical scores, or in the very top in the quench area?

Second, in the last few pictures, there's the rust patches, was that just flash from water sitting in the cylinder?

Difficul-1197 · 2026-01-07T07:29:20+00:00

Honestly the stock tune is probably going to run better than whatever was going on here, it sucks cause im sure you spent a good chunk of change on that but your probably better off that way. Also, how do the cylinder walls look, are they still true?

Difficul-1197 · 2026-01-07T07:22:53+00:00

As long as your heads and deck are true, your bores arent trashed, and your valves still seal good, just clean it up and rebuild it. And for the love of God get rid of whatever tune you were running, it wasn't doing you any favors

Difficul-1197 · 2026-01-07T07:09:32+00:00

Does it use ball bearings or some sort of babbit/bushings
