VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 alemite grease fittings on a 31 ,

Isee that there is 23 alemite grease fittings, does any one have a good map on were the 22%, 45%, 90%, and striaghts go? Iaint to good at this,might not even find the answer the next time I am on here, so here is my emaile rjppfaff@completebbs.com Thanks alot Roger

I saw one a long time ago... If someone would email it to me, I'd be happy to post it on the 1931chevrolet web site.

I think that the location and the different types of Alemite fittings were talked about here on Chevy Chatter II several years ago. A search on this site might bring it up.

It looks like I put the wrong email- it should be rtpfaff@completebbs.com Like Isaid Iaint to good at this. Anything on alemite fittings placement is a help. Thanks again Roger

Would that be true for a 29 also? This is the first time in my adventure that I heard there is a difference in the percentages. How can one tell the difference?

There are no "percentages" on the Alemite fittings. However, the Alemite fittings do come in different degrees....such as 45 degrees, 90 degrees and etc.

I think he meant 22 degree, 45 degree angle, etc. on the direction the grease zerks point.

well, likeIsaid Iaint no good at this. how about degrees. Thanks Roger

oops, I see the old JYD beat me to it! lol

Yep...and they are Alemite fittings not Zerk fittings.

My bad. I should have figured that out myself. Thanks for the clarification.

Chip sent this to me a couple years ago. It may help answer some questions in this thread.

The list of grease fittings for 1931 passenger and 1/2 ton trucks is below. All fittings are installed to be easiest to service from the outside of the vehicle (except for the left front spring shackle. Those are installed to not interfere with the operation of the pitman arm and connecting rod.)

JYD posted: "Yep...and they are Alemite fittings not Zerk fittings."

What is the difference between the two types? I assume this means they are not interchangeable - is that correct?

Thanks,
Mark

We had a good discussion on Alemite fittings here on CCII a couple of months ago. Anyway, the Alemite fittings are a double pin type whereas a special Alemite adaptor is used and it twists on the fitting and locks on the pins. A Zerk fitting is a round head type of fitting and the adaptor just pushes on to lock. This is the same type of fitting that is used on modern cars.

True, JYD, I should have said grease fittings, or more specificaly alemite fittings!!

JYD,

What year did Chevrolet start using the Zerk type (no pins) fittings?

Thanks,
Mark

1933 I think.

J-Y-D - My 1933 Eagle coupe had Alemite fittings. I personally changed them all to zerks 46 years ago. Being an early series model, there were some differences compared to other eagle models I have seen. Like my wing window handles are knobs instead of cranks and my trunk handle is like the '32s.

Roger

Yes, the early 1933 models definitely had the pin-type Alemite fittings. I did some checking in my Chevrolet literature and found that the Alemite pin-type fittings were changed to the new "Alemite Hydraulic Fitting" (Zerk) in July of 1933.

When I bought my '31 Coach, among a trunk full of old parts was a small box containing about 2 dozen of these strange little fittings with pins sticking out the sides. I had no idea what they were. While getting the engine rebuilt by an 80 year old mechanic, I pulled out the box to show him and he of course knew they were the original grease fittings, and that mine had been converted to the Zerk type likely 50 years earlier(car had not been on road for 45 years). They make a good souvenir, and I think I'll mark the box so the next owner knows what they are!.

That is a good idea, I gave up trying to grease my 28 with the Alimite fittings, using the Chinease Alimite grease adaptor,pulled them all , used a stiff wire to clear the grease path and screwed in Zerks. I cleaned up all the original Alimites, put them in a box and decided that if I ever had the car judged, (unlikely it is original except for the paint job) and added on door hinge mirrors battery and tires. I am like JYD I want to drive the old sister just like it is, We just throw an afgan over the old original pipe and cigarette burn spots and the dirty spots. I been told that I better replace the glass with safety glass, but not I, it is clear as a bell, no chips or cracks. If I did a lot to it and put a lot of money in it,I probably wouldn't want to drive her at 55 MPH once in a while, and listen to all the songs that the driveline sings!
Anyway, only a choice few old ladies and gents will ever get an invite to ride with us.

Wow. thanks for all response This is very good info. I hope you can keep all the infromation going. Ido thank you for all your thank less time and knowledge. You guys are great. Roger
