Guest jake1297 Posted October 7, 2015 Share Posted October 7, 2015 I picked up a restored 1934 Diamond T with 3 extra engines from an estate sale and am looking for some info. Or info where I can get info. I've been to Diamond T Classics and the site is old and unused also hard to navigate. Here's what I know: It's a 1934 Diamond TChassis # 89118Model 261GVW 12000 lb.Truck Wgt. 4820 4 speed tranny, top speed 44 mphHercules JXA engine What I'd like to know is: HP of the engine.Anything about this model, can't find a thing online.How many were produced? What is the production number of this one. I believe I read somewhere it was the last two numbers, or maybe the last three numbers of the chassis number. Any help would be appreciated Link to comment Share on other sites More sharing options...

Guest jake1297 Posted October 8, 2015 Share Posted October 8, 2015 Thanks to dictator27, any information is good information. I did change the oil a few days ago, not knowing how old it was. It took 6 quarts, to fill to the top line on the dip stick. In reference to the 4/4 mark. Being new to the old, I never heard that before. What is it's meaning?

dictator27 Posted October 10, 2015 Share Posted October 10, 2015 4/4 simply means it is full. It does not mean it takes 4 quarts. Engines which take 20 quarts have the same marking. Probably the same dipstick since it is the depth of the oil pan that changes.Terry Link to comment Share on other sites More sharing options...

Dandy Dave Posted February 25, 2016 Share Posted February 25, 2016 From my American Truck Spotters Guide. A model 261 is a two ton truck. Confirmed a 1934. 1933's and 1934's were basically unchanged for those model years. In summer of 1933 the Deluxe model was introduced with a V windshield and styled Grill. Would like to see some photos. Dandy Dave! Link to comment Share on other sites More sharing options...
Bud Tierney Posted February 25, 2016 Share Posted February 25, 2016 As mentioned, diamondtclassics seems to've fallen on hard times, a real shame... You might try checking out ATHS---American/Antique?? Truck Historical Society Justoldtrucks....altho both heavily concentrated in more modern stuff, still good resouces for info/other DT owners, AND justoldtrucks has a parts rebuilder, parts restorer, parts sources list in their Vendors and Restorers section... The Antique Car/Truck forum on smokstak... There's another very small site: antiquetruckclubofamerica, but, like the above, free, so why not??... DT was involved with Reo for awhile (DiamondReos); I know the Reo club include anything Reo, trucks included, but don't know if they've tried to include older DTs to compensate for the DT website mouldering...

Ivan Saxton Posted March 5, 2016 Share Posted March 5, 2016 If your 1934 Diamond T was built for a top speed of 44 mph, that was quick. My father's timber mill company had a wartime tandem drive Diamond T and Rodgers trailer, that was set up to transport army tanks. He knew what he was doing in the war surplus auctions, and split up the day's cash for purchases between himself and several others. Ben Baxter was the foreman of the engineers' shop at the mill with discretion and responsibility; and this beautiful rig was sold to his final bid of 800 pounds, which was his entire budget for the day. He drove out the gate, and as he started to drive into the partnership's compound straight across the road, someone yelled at him that there was no entry permitted to the army!.... My father was less than pleased, because that was all they could buy with a quarter of the day's budget. Ben pointed out that they did not have another heavy tandem drive truck, and they frequently needed to transport heavy loads. It was a brand new truck, the tyres ware new, it ran on diesel, and it did not really matter that it was left hand drive because the driver could see over anything ahead. Well, they soon parked the Rodgers trailer, and set it up with a lowloader semi. It had a Hercules diesel engine, the same as used in Oliver Cletrac FD and FDE bulldozers. It made a lot of money, and saved a lot of money; And seven years later when it was replaced by something less patient, it sold for 8 or 9 times what was paid for it. The driver was never stopped or bothered by the Transport Regulation Board; and when he did met one of their people socially, the fellow told him they had tailed him for countless miles, at 28 miles per hour maximum. So, you can be pleased that yours is a quick one; and you wont get your feet tangled in your beard, driving it to meets. Link to comment Share on other sites More sharing options...

PuttPutt14 Posted November 6, 2023 Share Posted November 6, 2023 Which radiator cap would be correct for my 1929 Diamond T 502,505,550 truck? Where could i locate one that would work? Is the coolant system a pressurized system or should the cap have vent holes? Thanks Link to comment Share on other sites More sharing options...
paulrhd29nz Posted November 7, 2023 Share Posted November 7, 2023 You might want to start your own thread. You’ll get more exposure. your cooling system is atmospheric. You’ll blow your rad at any pressure above atmospheric pressure. cool truck. Good luck !! 1 Link to comment Share on other sites More sharing options...
