1928 parts list illustration of 5 yard water level dump body, made with heavy oak plank lined with sheet iron. 1928 vintage Linn sled steerage. Model 70 Brown Lipe reversing transmission, mounted behind the standard transmission, allowed same speeds/ratios in either direction, as they found it more practical to reverse rather than turn around, as an option they had a auxillary seat on the running board with extended pedals so you could literally operate from outside the cab for short hauls from shovel to dumpsite. This was replaced by a reversing transmission mounted behind the clutch, something the Linn Corp. also held patent on. It also allowed uninterupted PTO function.

These are some of the most essential parts of a Linn tractor, the drive sprockets, need to have good teeth, made of manganese steel you can't easily weld them up. Double reduction unit, made for Linn by Brown Lipe Chapin of Syracuse, may have some interchangeable parts with other 5 to 8 ton trucks of similar vintage but the final drive axles or "jackshafts" are equally rare, and specially developed by Linn. Later Linn model 3000 differential, originially developed for the high speed military V-12 units, they had to retrofit the first tractors equipped with them for lower gearing (including Gushee's # 2500). If you think you have these parts or know wher ethey are, contact Gushee or some othe rLinn owner as they are well worth sdaving and not as common as the engines and transmissions were.

The 40 HP Continental E4 used in the first Linn tractors (like # 1) up through about 1920. Then after brief flirtations with Stearns and Wisconsin 4 cyl. engines they went to Waukesha 4 cyl. EU 60 hp, then the GU in 75 hp. Also in 1924 they went to the 6AB 100 hp 6 cyl. Waukesha as an option, found much more useful for snow removal, later replaced about 1931 by the beefier 100 hp 6RB and then 6RBR models offered up until WW2. The Hercules 6 cyl. HXB and then HXE (935 cubic inch) engines became popular in the mid 1930's for those demanding more speed and horsepower, and also came in diesel versions (but Cummins was more popular).

Early Linn differential made by Brown Lipe Chapin after they abandonned the 3-speed Cotta unit, as they upgraded engines they had to modify the jackshaft construction, which can denote specific vintage/model of tractor. Then in the 1923 models they went to the first round "pumpkin" style differential used from then on. 1922 catalog showing track construction, Linn's novel feature was spool type rollers that stayed on a ride over seperate "runner blocks" which can pivot, and that allows the full contour following traction, 100% ground contact at all times, unlike rigid track systems. Early Waukesha powered Linns (Hartford was used with Continental) used a multi-disc clutch before they went to twin or single disc clutch plates, I'm not sure what they thought the advantage would be? One of H.H. Linn's 19 patents was for the brake system, steel on steel, like railroad brake shoes, replacing the original Raybestos brake bands on the track idler (front) sprockets which required an addition emergency type brake, (as seen on Linn # 1).

7351 Fuller 8 speed and 7341 4 speed (used with 4 cyl. and diesels) replaced the Brown Lipe 7351 5 speed and 7341 4 speed units after Spicer moved operations out to Toledo, OH by the late 1930's.

Brown Lipe 60 and control set in a Larrabee (built in Binghamton). A restored Brown Lipe 60 overhead shift Linn switched to from the sideshift with the 1925 models. WC Lipe single plate clutch more commonly used with Waukesha. H.H. Linn's patented universal joint (replacing Merchant & Evans).

Linn began using the HA model Cummins Diesel 6 cyl. in 1932, this data is for the subsequent 5x6 HB, they would later use the HRB and HRI-600 and then after WW2 bought them army surplus from the Watervleit Arsenal near Albany right up through 1952. While they also used Hercules diesel, Cummins were always the favorite, the low rpm powerful torque was favored by many for snow removal work, IF the municipality could afford it.

HRB and HRI 600 Cummins engine specs used by Linn (and many others) in the 1940's and early 1950's.

Hercules diesel engine specs, diesel version of the HXE, the DFXE, they also used the smaller DRXB Hercules in the C-series Linns.

Custom made aluminum cylinder doors for 6 cyl. Waukesha engines. The 6AL engine was used by Linn but had bearing issues so they swopped out for 6RB, Joey Barnes told me about finding one up in Manitoba at an old Linn garage site. Specification charts for 4 and 6 cylinder Waukesha gas engines, Linn upgraded from the 60 hp EU 4 cylinder to 75 hp GU and then went to the 100 hp HS and HL "Big Four" engines in 1928, which were the lowest cost model, popular with highway departments and contractors.
