carlotpilot Posted December 27, 2020 Share Posted December 27, 2020 no pinion shaft that i`ve ever seen has only three teeth on it . check the number stamped on the yoke end that will tell you exactly what ratio you have .

Joey Mack Posted December 27, 2020 Author Share Posted December 27, 2020 yes sir's..... what I mean is ... the yoke rotated a little over 3 1/4 turns to make the wheel rotate once. That's how I got 3.30:1.. ish.. I will still look for numbers on the yoke..

Quickfarms Posted December 28, 2020 Share Posted December 28, 2020 On 12/27/2020 at 11:37 AM, Joey Mack said: Hello, Quick farms... I raised one wheel and marked it and the yoke. I turned the wheels and got a small bit more than 3 1/4 turns. I figured it would be about a 3.30:1 ratio, but another "poster" said I need to double that number.... So that would be 6.60:1.... Any thoughts? I cant imagine it would have highway gears... Yes with only one tire in the air you have to rotate the tire two revolutions to get the gear ratio. if you don’t want to change the drivetrain you have a 45 mph truck there. If you put 9-20’s on it and a overdrive, from a large pickup, you will have a nice local toy. if you want to haul a camper then it needs a drivetrain swap. For my Chevy I am looking for a K30 and doing a body swap. My friends think I should put an LS motor in it Quote Link to comment https://www.bigmacktrucks.com/topic/65376-1948-international-kb-7/page/2/#findComment-466257 Share on other sites More sharing options...
Freightrain Posted December 28, 2020 Share Posted December 28, 2020 Very solid looking truck. Might look at maybe a flatbed with some gin poles on it? That might come in handy to move stuff around(if you have big stuff). The flat bed would give you plenty of room to haul things too. 1 Quote Larry 1959 B61 Liv'n Large......................

Joey Mack Posted December 28, 2020 Author Share Posted December 28, 2020 Thanks quickfarms... for clearing up my Q's.... It already has new 9.00' s on it.. factory 5spd..... To be honest, I'm done going fast anymore... I like low geared power, and it's a very cool looking truck....

Joey Mack Posted December 29, 2020 Author Share Posted December 29, 2020 Thanks freightrain, I figure that's what I'm going to do.. I will take it to the grocery store... Butt I also get pallets of truck parts for my business, I can certainly do better with this one. I have a '77 C-30 flat bed, 350 c.i.d., granny gear 4spd... It serves me well, but the KB, well anyway...

HarryS Posted December 29, 2020 Share Posted December 29, 2020 Another thing to consider for a little more speed would be a two speed rear. I had a '48 Diamond T that topped out at just over 50 mph. I found a vacuum operated two speed that got it up to about 58 mph. It also gives better gear spacing. Do you know if your five speed has OD?

Joey Mack Posted December 29, 2020 Author Share Posted December 29, 2020 I saw that they made them with 2spd rears... Once I get it on the road, i will see what it can do, I'm guessing no more than 55-60 mph, but if the low range power is there, that will be fine too... The G.V.W. is #16,500,, I do not know if it's an O.D. tranny yet... I haven't done anything to it since I got it.. I've been busy with business. But since I posted this, I've been getting Itchy!! 🤫..I will get under it and look at the tranny for I.D...Thanks, Jojo Quote Link to comment https://www.bigmacktrucks.com/topic/65376-1948-international-kb-7/page/2/#findComment-466274 Share on other sites More sharing options...
tjc transport Posted December 29, 2020 Share Posted December 29, 2020 i ran a 49 L-190 for years. six cylinder gas with 5 speed and two speed rear. in low it was slow, around 45-50 mph. but high rear would run 75mph. 2 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Joey Mack Posted January 1, 2021 Author Share Posted January 1, 2021 Well, I tried to find tranny I.D..... All I found was: 3-4-R.... and, 95903-H...

Popular Post Joey Mack Posted April 26, 2021 Author Popular Post Share Posted April 26, 2021 Well after 7 months of lookin at her.... I pushed it in the shop. I hung a lawn mower gas tank with an in-line filter, like an I.V at the hospital, to feed the carb, and amazingly. it fired right up without ether.. I was happy to see the alt. and oil pressure gauge work. of course the carb gaskets are dry, so fuel leaked out. no sweat I just lowered the tank below the carb and let it clear out.. it had great throttle response... going to re-build the carb and, well.... keep going.. As you can see.. I have 3 helpers in my shop.. jojo 4 3 Quote Link to comment https://www.bigmacktrucks.com/topic/65376-1948-international-kb-7/page/2/#findComment-473010 Share on other sites More sharing options...

Joey Mack Posted April 27, 2021 Author Share Posted April 27, 2021 Carb kit will be here in the morning. now i'm searching for a brake master cyl. I may put a 1ton chevy one on there with 2 chambers. I dont intend on working this truck at all, so I think I can bypass the old rusted vacuum booster and use the chevy master cyl. I would appreciate any opinions. i will look to see if there is a uni-fit booster master combo that fits in small spaces..... Thanks for the support.

Joey Mack Posted April 27, 2021 Author Share Posted April 27, 2021 good thing i'm hungry... I have words to eat....

tjc transport Posted April 27, 2021 Share Posted April 27, 2021 a popular booster/master swap on the ford falcon forums was a chevy geo unit. it was small enough to fit under the fender braces where the old "mayonnaise jar" master was.

tjc transport Posted April 28, 2021 Share Posted April 28, 2021 unfortunately that i can't remember. and the servers did a crash and burn, so we lost 21 years of forum info. so i can't even go back to look it up. i did just google it and see it is the geo metro unit that fits. has a 7 inch booster. here is a short video with the parts needed for the 64-65 falcon: Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..

Joey Mack Posted April 28, 2021 Author Share Posted April 28, 2021 i looked up a metro unit... thats cool thanks again.. I'm going to bypass the old system and get the lines set up to hook to a new type of set up. I have a lot of room to do that work. there is already new lines and I think the wheel cyls are new too.. of course when i put fluid pressure to them, the truth will come out....

Joey Mack Posted April 28, 2021 Author Share Posted April 28, 2021 Well..... I backed it out of the shop today after re-building the carb.. the hand brake works good, I tried to shift gears but... she aint ready for that yet,,,, or is it me whos not ready.. anyway, I need to get it tuned so it runs better, it shut off a couple times but fired right up. I also have to put a resistor on the coil, its getting hot. this truck is positive ground, i wonder if i need to wire the coil backwards? any thoughts? i have no practical knowledge of positive ground wiring, Jojo Quote Link to comment https://www.bigmacktrucks.com/topic/65376-1948-international-kb-7/page/2/#findComment-473103 Share on other sites More sharing options...
