Guest RagsNB Posted November 14, 2015 Share Posted November 14, 2015 Hi all, I had this in the "What is it" category and a fellow suggested I post it here in Buick pre war as it would appear from initial ID is a buick rear end from 1916 to 1925 era. I attached some photos all sides all angles with some serial numbers and forge numbers.Distances - Axle length, inside wheel hub to hub at the backing plate 50 inches across axle. Differential circumference 38 inches around ring just outside of housing mount to differential case. Drive shaft length, from ball end where tranny hooks up to differential case at housing bolt edge 58 inches. Im told looks like 1916 to 23 also that its Buick and some ideas of it being mid 20s and a 6 cylinder engine configuration. I dont know found it in a field trying to match up a rear end for a 1919 Gray Dort speedster dirt track racer. RagsAKA Mark Link to comment Share on other sites More sharing options...
dibarlaw Posted November 14, 2015 Share Posted November 14, 2015 I guess I will have to crawl under my 1925-25 and take some measurements. And check for any numbers. What size are the drums? It definitely looks like a mid 1920s axle. Link to comment Share on other sites More sharing options...
Dwight Romberger Posted November 14, 2015 Share Posted November 14, 2015 I will look also. I have a '22 4cyl. Buick How about some pics of the speedster? Link to comment Share on other sites More sharing options...
Dave_B Posted November 14, 2015 Share Posted November 14, 2015 I'll go out on a limb and say it's a 25 to 27 Standard. It's pre 28 because it does not have the connection for the shock straps. Dave 1 Link to comment Share on other sites More sharing options...
garnetkid Posted November 14, 2015 Share Posted November 14, 2015 I just went out and had a look at my 25-40 parts frame and the measurements from backing plate to backing plate are the same (50in). the length of the drive shaft minus the ball attachment is 54" so I suspect that is very close to your measurement. If the diameter of your hub cap is approx 3.5 inches that would make it the large master series car as well. here are some pictures of mine. When Leif checks this file he may be able to shed more light on the numbers. I am also curious about the apparent factory painted on silver numbers that are still showing on mine after all these years. Leon Link to comment Share on other sites More sharing options...
ROD W Posted November 14, 2015 Share Posted November 14, 2015 It is a standard as it has the half floating axle with the twelve wheel bolts not the six of the master. They changed the length of the brake actuating levers between 25 and 26. From memory the 25 had a longer lever/arm than the 26 and 27. In the picture it looks like the longer arm so my guess is a 25 standard. Larry D should be able to confirm if the drum break mechanism is the same as his. 40 years ago I had a 25 standard and picked up a 26 standard for spare parts but found that not many parts were interchangeable Link to comment Share on other sites More sharing options...
garnetkid Posted November 15, 2015 Share Posted November 15, 2015 You are right with it being a standard six Rod. I should have picked up on that, didn't pay enough attention to the pictures!! Leon Link to comment Share on other sites More sharing options...
Guest RagsNB Posted November 15, 2015 Share Posted November 15, 2015 (edited) Thanks guys thats very good input!Diberlaw....I will measure drum tomorrow toys are all down at my garage in next town. Its a perfect man cave old 1920s Ford Dealership garage 100 feet long 40 feet deep hoist, crane, pit, 3 bays. Dewight.....the speedster is a basket case im trying to put together for Race of Gentlemen 2016, I raced my 42 Harley there this fall after restoration. The reason it will be a speedster is theres not much to it and Gray Dorts are the rarest of the rare so little chance I will find the parts to restore it. I have a rad to tranny that runs and thats all. Need frame, rear end drive train front and rear axle body around front cab area the rest I will build as a boat tail rear end. I will attach the start of the project. So the photos plus the rear end above is all I have now have the winter. That 1919 Gray dort actually works! buddy had it set up to run a saw mill.Garnetkid.....thanks your photos look really close to mine so yours is 25? Your measurements are almost bang on also.

Guest RagsNB Posted November 16, 2015 Share Posted November 16, 2015 I measured the wheel and hub cap.for Debarlaw the wheel hub is 41 inches in circumference.for Gaenetkid as requested the hub cap is 3 1/4 to 3 1/2 inches across. Rags Link to comment Share on other sites More sharing options...
ROD W Posted November 16, 2015 Share Posted November 16, 2015 (edited) Rags, The 26 and 27 had two adjustment nuts for the brake bands.( around the brake drums) a nut at each end. whereas the 25 had only one long break band adjustment nut. Also the 25 had a smaller hub than the 26 and 27. I seem to remember that Dibarlaw said in a previous post that he had 21" wheels which probably means he has a 1926 diff and rear axle, as the 26 is splined at the diff end of the axle where as the 25 is square. I had to change my 25 over to 21 inch wheels as the spider/planetary gears were broken due to the square axle.

Hubert_25-25 Posted November 21, 2015 Share Posted November 21, 2015 I have a 25-25 Touring. The outside diameter of the brake drum is 12 1/4 inches. Are you able to remove the wheel nut so that you can pull off the wheel hub to measure the diameter of the brake drum accurately? 2 other part numbers that would help. The brake lever casting that is shaped like a question mark will have a 6 digit part number. If you can remove the wheel, there is a curved arm on the backing plate that operates the internal parking brake. This may not have gotten exposed to the elements, and it will have a 6 digit part number on it. I may be interested in this if it is correct for my car. Best Regards, Hugh Link to comment Share on other sites More sharing options...
Guest RagsNB Posted November 23, 2015 Share Posted November 23, 2015 Gr8 Thanks for input. I will try and get the axle /hub nut off and check out inside of the brake drum and check for part numbers.

Hubert_25-25 Posted November 24, 2015 Share Posted November 24, 2015 The rear axle is for a Buick Standard given the 12 hub bolts (6 are on a Master). Pulling the wheel off the axle may be difficult. but here is what you will find on the internal curved brake arm. part152954 is 1922-23157364 is 1924172389 is 1925 - 1929 standard The external brake arm (shaped like a question mark) matches the following yearspart (2 part numbers for left and right)151402 or 151403 is 1922-23 169714 or 169715 is 1924 -1925196434 or 196435 is 1926-1929 You may not want to pull the hub, but start with wire brushing the outer brake arm first. Picture is of a 25-25 hub. Best Regards. Link to comment Share on other sites More sharing options...
