Speedometer Repair

[JBJeep]

My speedometer just quit working in my newly restored M38A1.
It's original and I just had a new lens case put on it, so I'd rather repair than replace.

Can anyone recommend a shop?
Preferably, someone with experience with these because of the sealed case.

Thanks

You can give Bob's Speedometer a try. I know a couple of people who have use them and were happy with the results. However, they are not cheap!

Broken cable?

Still checking the cable, my mechanical mastermind is out of town and I'm out of my depth.
But, during the restoration the cable was checked and lubed,
So assuming the worst...

Anyone have a 8376375 or the earlier 7760396.
My G-758 manual says that will fit instrument clusters with different part numbers, I do not know if that means they would NOT work in mine.

Also, since my manual is dated 1956, it doesn't say if there are later part numbers which will work.

I thought of Bob's due to their ads in various places.
However, I was warned to stay away from them by a MV restorer/dealer/parts source I trust.
I do not know what his opinion is based on...
I have nothing against them, but I know enough to listen to guys who know more than me.

The new case was installed by a shop recommended by John at Midwest Military.
That was my first stop.
He told me the shop was closed, I suspect the guy retired.

As far as a new unit, even just to keep one as a spare,
I checked the usual military Jeep parts vendors (as mentioned by RonD2 above):, three have repros which lack the correct markings...they have the later "MS" numbers,
one has a pricey NOS (unknown markings...I am awaiting a reply on that),
one has a later NOS unit which may or may not work.
My parts manual is a reprint of the original which obviously does not list later units.

And be sure and operate the drill in reverse.

I didn't say which way on the drill because I have way to many different systems on my tray all the time. If any speedo check doesn't show activity in one direction the common sense thing to do is switch directions. Not a lot of choices. Only two.

JB, I noticed you said this in your original post: "It's original and I just had a new lens case put on it"

And the shop retired already!

Thanks, I bought it.
Not a bad price for a new correct unit (albeit an older version).

You're welcome.

And in case you need it, here's a NOS cable:

JB,

Thanks.
Looking my manual I was checking the Speedo part numbers but failed to cross reference the gauge numbers a few inches above (duh!!!).

Okay, I bought the early M38A1 Speedo 7760396 as seen in the photo (in fact the eBay page where I bought that had the same photo).

Now my problem is will it fit my late A1?.
The manual says the cluster 7148835 was used up to serial 70114.
My A1 is 82551.
So, will it work?

A very reputable Jeep parts guy offered me the same unit, so he didn't have any concerns, likewise, the various repro units and the later military "MS" marked gauges do not mention a serial range for application.


Your red notes seem to indicate the later (non-luminous Speedos were used as replacements in early A1, so I should be okay.
Any thoughts?

I appreciate your patience.
