Help ID this jack.

[Tom H.]

Can anyone positively identify this jack for me. I'd like to know if it would be correct for a January 63. I'm having trouble distinguishing the difference between type 1, 2 and 3. I know it is for 63 to 66 since it has no date. It also has the A on top. Thanks for the help.

Looks like a C-3 jack to me

I don't think so. I've got 3 C3's in my collection and the jacks are quite different in them.

Hi Tom,
It's kind of hard to tell from the picture but it does look very similar to my '63 type 1 jack.

Thanks Syd

If you look at yours compared to my photo, the right side of my photo shows the nut end U brace turned in, is yours that way ?? Also, the left side of my photo shows the bearing. Does yours also have a bearing instead of just a washer ?? If yours is indeed like the one in my photo, has it passed judging ?? Thanks.

Re: Help ID this jack.

The jack pictured looks like a Type III with a Type I & II bearing.

Type III's were used from very late '65 (20,000 and something) through '67.

Joew Ray did a survey and the article with descriptions and illustrations of the 3 types was in the Winter '85 Restorer......available on CD in the NCRS store.

Tom,
The jack is not currently with me to verify but I can check on it tomorrow for you.
I do know that it does have the sealed bearing and yes, it did pass judging (chapter level) twice.

Checking my 63-64 JM, I was reminded that you can also distinguish beween the type 1 and type 2 jacks by the presence of a reinforcement stamping on the lifting arm. Your jack should have flat lifting arms to be correct for Jan.'63.

A very complex issue...jacks!

Basically, both Type 1 and Type 2 jacks shared the ball bearing assy between the hex drive nut and the jack frame. The key difference is whether the lift arms are stamped with reinforcing 'gussets' or simply formed from flat stock, stamped sheet steel.

The trunion being turned in/out is a running change Noland Adams identifies along with the length of the hex drive nut (longer nuts, approximately 0.78 inches vs. 0.5x inches, used after 3/22/65). The Type 3 jack is pretty obvious as the drive bearing was cost reduced going from a ball bearing assy to a stack of washers (two steel washers separated by an acetal resin bearing material)...

Folks who read Noland's description to isolate all the differences and boil them down to three jacks which isn't possible since some of the issues (trunion in/out, and length of hex drive) were running changes.

Thanks Jack !

This jack seems strange, in that it has the bearing assy, but also appears to have the gussetts. Would I be safe to assume that with this one having the gussetts, it would be incorrect for judging in my 63 ?
