Bacon Farms Posted May 5 Share Posted May 5 Hello, I am new to the forum. I just picked up a replacement for my 1980 S1800 5-6 yard dump on 20" two piece dayton style rims. My new truck is a 1984 S1700 on 19.5's with 6 hole budd rims. I picked up a vintage brochure from that time period, and it has all of the info for my new truck, but no detail as far as wheels and tires go. And, I haven't found any pictures on the innerweb with six hole budd 19.5 wheels. They look small in the big wheel opening, but so do the freightliners with 19.5's, etc. And, I haven't been too succesfull breaking down the VIN either. Not sure the VIN would have the tire size in it anyway. So, my truck has a 345 gasser, 4 speed (as advertised, truck not here yet to confirm) and has a new 5 yard dump bed on it, even though with 4400 pound rated tires, I would be looking at a 3-yarder. The cab and chassis are rust free. The truck has new brakes and rubber lines and discs all around. My older truck had only a farm brake. Hopefully, I will be able to go to town and get a load of granite with this rig. Anyway, what about the 19.5's ? Thanks, Carl First order of business is some Red paint from the paint store!

As to Bacon Farms, welcome to the forum You may try posting your questions in the IH Trucks sub forum on down the forum list if you don't get your answer here. On a completely semi unrelated sorta note, my '62 F250 4x4 had 19.5's as an option in the owners manual. Good luck! 1 Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted May 5 Share Posted May 5 Gasser Huh? Maybe adding another fuel tank wouldn't hurt either 2 Quote Link to comment Share on other sites More sharing options...

Binderoid Posted May 5 Share Posted May 5 What about the 19.5s..... like what, for instance? What exactly are you trying to accomplish? Quote Link to comment Share on other sites More sharing options...

Sorry, I guess I didn't explain it well. Just wondering if they are stock equipment for this S1700. And that it didn't come with 20's or 21.5's. Again, haven't seen any before on this style IH. Thanks. Quote Link to comment Share on other sites More sharing options...

acem Posted May 6 Share Posted May 6 I expect someone put the 19.5 tires on to lower the truck. They were common on u haul type trucks. I expect you can replace them with 20 or 22.5 tire/rim assemblies. Welcome to the forum. Thx-Ace Quote Link to comment Share on other sites More sharing options...
ray54 Posted May 6 Share Posted May 6 Welcome , and thanks for starting with pictures. 4400 x 6 =26400 pounds gross I thought that was about how much you call a full load on 2 axle like that. 😉 As farmer we can add a ton or even 2 more , as long as we don't figure on seeing a DOT officer on our back road. My guess is that might not be the size your truck left the factory on. So somebody else payed to get the new tubeless rims in a size that is easier to find today. But if you want old lock ring wheels that have 900 x 20's on I will trade you. Quote Link to comment Share on other sites More sharing options...

Bacon Farms Posted May 6 Author Share Posted May 6 Thanks for moving to the appropriate board. A buddy suggested that we take it for a ride when it gets here and see if it will cruse at 55. If we can't make 55, then the 19.5's are wrong. That's his take. I do have a full set of one piece 22.5, 6 hole budd wheels, that I am saving for a different project, but if I need them, I will have to use them. They are from Military and are 7.5 inch wide. More to follow on that front. Thanks for the reply's Quote Link to comment Share on other sites More sharing options...
acem Posted May 11 Share Posted May 11 I've got a 75 loadstar that's so low geared it screams at 55 MPH. I usually cruise her closer to 45... Quote Link to comment Share on other sites More sharing options...
R190 Posted May 12 Share Posted May 12 I think every UHAUL IH chassis I have seen came from the factory with 19.5s and a lot of ambulance and fire /rescue trucks in this area. Not that uncommon I think they were standard on the low profile chassis series ( the ones with taperd frames). Quote Link to comment Share on other sites More sharing options...
Bacon Farms Posted May 15 Author Share Posted May 15 Well, I just got it home and took a quick spin on a back road. Not sure yet, but I only got it up to 35, however it seemed fine. Its a 5 speed and 1st is not super low, so not sure if it's a "granny gear". Feels like it should go 55 with ease. When I get plates and insurance, I will put a tach inside the cab and take it out on the highway. BTW, the brakes work fantastic. More to come.

Bacon Farms Posted May 28 Author Share Posted May 28 OK, so I have had it home for a couple weeks. The updates so far. The "12-volt" electric hydro pump has plenty of power, but not enough pump volume, so even though I am retired, I don't have that much time left to wait for the box to come back down. I have ID'd the transmisson and will look into a PTO pump, etc. As I said, I can tell you that the transmission is a Clark 455, actual number is CL-455-20. From what I can find its a 5-speed without OD. I can find the proper PTO for it too. What I can't find is the rest of the gear ratio's. I don't think it has a very deep "granny" gear, but not sure. If anyone can tell me the gear ratio's, that would be great. I have it registered and am waiting for the FARM plates to come in the mail. I did take it out on the highway with my co-pilot on his GPS. I settled into a nice cruise speed indicated on the speedometer as 56 mph. The GPS read 50 mph, and that is what it felt like judging by all the other traffic. It really didn't want to go any faster, but the engine wasn't screaming either. I believe it's supposed to have 900-20's on it, but not sure. I sent for a line-set card, and hope that can shed some light on that. I am bidding on a unique trailer that has 6, 6-hole 22.5 budd wheels and tires on it, so if I win that I will swap the wheels/tires if the "card" calls for the bigger tires. And I do have a set of 6 hole budd 22.5 ex-Military wheels that will work too. I did give the interior a bath today as I couldn't stand the potatoe farm smell anymore. Brother says I need to get a couple of them trees to hang from the mirror, LOL. I picked up a brand new chrome semi front bumper a couple years ago, so that will have to go on it. Iowa-80, LOL. And I need to pick up a couple gallons IH red and a roller... Again, any help with the gear ratios, that would be great. I might try and get a number off the rearend to see if I can ID that in the time being. Thanks Quote Link to comment Share on other sites More sharing options...

Bacon Farms Posted May 30 Author Share Posted May 30 I did take a look at the rear differential and could not find a tag, but I did find casting numbers. 69013 R3 TN 2312 Probably not enough info to figure out the gear ratio, but I don't know that for sure. All new to me. There is a tag on the housing, HAYES-DAYNA INC. SERIAL B540 300847 DATE 122383 HIGH STRENGTH STEEL DO NOT WELD Thanks for looking..

ryangpayne Posted June 1 Share Posted June 1 I am not up on the differential data. I would kind of wonder if the 540 on the first of the serial number could be the ratio but that’s a complete shot in the dark. You could always jack up the rear end, put a mark on the tire and a mark on the driveshaft and see how many turns the driveshaft made for one turn of the wheel. -Ryan 1 Quote Link to comment Share on other sites More sharing options...
DR.EVIL Posted June 2 Share Posted June 2 I agree with payneryang, figure out your axle ratio. That's the most important factor in how the truck will perform with a load. The township road Commissioner had two C65 Chevies, a '67 with a higher numerical ratio, it plowed snow like a BEAST, accelerated relatively quick, but highway cruising was not one of it's best traits. They got a '74 C65, same 366 V8, same chassis, load capacity axles, only the rear axle, both low & high side were numerically lower, it could easily cruise 65 where the '67 was limited to around 55. But it was surprising how much easier the '67 climbed hills and help it's speed, the '74 slowed almost enought I'd need to drop to the low side. As a general rule I loaded them slightly more than their rated load, think they were both 26,000# and I'd load them around 28,000#. I would think the 345 IH would be kinda slow on acceleration, and I'd think you need to keep it up around full load RPM. Something like a 392 would have been a better engine. The trucking Co. I drove for had several IH S1700's I think they were, single axle semi-tractors with 3208 Cat's and 5+2, I spotted lots of trailers with them loaded with 40,000#+ loads. They had welded steel boxes wedged between the rear axle housings and frame rails to carry the weight. FARMALL rented me an IH S2200 single axle tractor, 290 Cummins & 9-speed Roadranger, rear axle was HEAVY, 34,000#, I spotted trailers during most of the strike in '79&'80. One trailer had 32,000# loaded in the front 16 feet of the 45 ft length, It was a royal P-I-T-A to hook up to. I started carrying wood blocks with me to back the tractors rear axle onto so I could get under that trailer. 1 Quote Link to comment Share on other sites More sharing options...
DWF Posted June 3 Share Posted June 3 Pertaining to finding the axle ratio. On a lot of the older trucks on the end of the pinion shaft where the yoke is held on with a nut there were numbers stamped in there. One number was the teeth on the pinion which would be the lower number and the other number would be the teeth on the ring gear. Divide the ring gear teeth by the pinion teeth and this gives the ratio. DWF 1 Quote Link to comment Share on other sites More sharing options...
Bacon Farms Posted June 5 Author Share Posted June 5 Hopefully, I will be going to pick up my cousin at Michigan Truck Spring on Friday and can pick up a replacement spring for the passanger rear. The spring eye is busted out. He is dropping his semi for new kingpins. Probably take the broke one off and up there for comparison. That's the plan. Added a bit of bling to the truck on Friday. I picked up the bumper at a equipment auction for 100 bucks a couple years ago. Pictures are bad. Poor timing with sun behind truck. Oh, well, I'm lucky I'm not a photographer. Thanks for the comments! 1 Quote Link to comment Share on other sites More sharing options...
Bacon Farms Posted June 9 Author Share Posted June 9 Dropped off the spring this morning. Walked accross the parking lot to the IH dealer and the parts guy printed me a line ticket. I bought two boxes of shop towels from him, so I contributed. So, the truck DID come with 19.5's from the factory. 8R19.5's to be exact. I'm happy about that as I can change them on my tire machine. Biggins, not so much. Other items of note; ENGINE 345 LPG, (I was guessing on that cause the dash had Propane fuel written where the fuel guage would normally be) GOVENOR FOR PROPANE ENGINE, (not present, must have been removed when they added the Holley 2-barrel) TEMPORARY LPG TANK, (this leads me to belive it may have been a truck for filling home propane tanks when new) 5000 # FT AXLE, HEAVY DUTY FRONT SPRINGS, (lightest axle for that model and year according to IH brochure, not sure on HD springs) 15000 # REAR AXLE, 4500 SINGLE LEAF AUX REAR, (lightest rear axle for that model, not sure about where the aux leaf comes in for rating) GVWR 19,501, (I will scale truck total, front and then rear and come up with a load capacity) PAINT CODE 0413, (will have to look this one up) Anyway, get your line ticket if you need to know the specifics for your ride!! Beats guessing and bar talk all day long.. Just sayin. 1 Quote Link to comment Share on other sites More sharing options...
