Popular Post Ezrider Posted February 16, 2018 Popular Post Share Posted February 16, 2018 no video today. but there may be one next week showing how i finally actually got the thing apart. started changing king pins on the mack, they turned out to be the most suborn kingpins iv ever done to date. (my Mack is a mutt with Eaton axles) started at them with a big drift and a 20 lb sledge hammer and some heat had already been at it a little while. wasn't recording at the time but gave my drift a mighty wallop with a 20 lb sledge hammer and all of a sudden i am seeing stars. not really sure exactly how it happened never even saw it coming but my drift flew back with vengeance and knocked me just to the lower left of my nose. whole left side of my face is swole up black eye and i think it knocked about 8 teeth loose......lol really would not be surprised if there is a fracture in my cheekbone. in the end took every bit of 40k lbs of hydraulic force and then maybe some. plus some heat before they finally decided they wanted to come out. thankfully still have both my eyes, i did have normal safety glasses on but it knocked them clean off my head. the impact was below them anyway but im not sure they would have been effective against a 1 inch drift flying threw the air at mach 2. thankfully still in one piece even if i may look a little funny have trouble chewing and so on and so forth don't think there is anything that won't heal anyway......lol 3 Quote Link to comment https://www.bigmacktrucks.com/topic/52533-bull-dog-bit-back/ Share on other sites More sharing options...

Ezrider Posted February 16, 2018 Author Share Posted February 16, 2018 the wedge bolts? yes well aware of them, and yes they were removed. the kingpins are out now they were just very tightly seized in the axle eye.

1958 F.W.D. Posted February 16, 2018 Share Posted February 16, 2018 WOW! Glad you are OK. Sounds like the fight I had with a set of pins on a Ford L-9000 tractor when I worked at Jevic. Lots of oxygen/acetylene and swings with a 20 pound sledge. No injuries though except sore shoulders. 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment https://www.bigmacktrucks.com/topic/52533-bull-dog-bit-back/#findComment-392187 Share on other sites More sharing options...
Timmyb Posted February 18, 2018 Share Posted February 18, 2018 I watched my mate do some stubborn king pins once. He ended up using a hollow ram with a nut welded on the pin and threaded rod inside the ram. I don’t have that sorta equipment so I leave well enough alone! I think you deserve to put your feet up after that effort. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/52533-bull-dog-bit-back/#findComment-392334 Share on other sites More sharing options...
RowdyRebel Posted February 18, 2018 Share Posted February 18, 2018 I don't know anything other than the way my truck's kingpins seem to work (appear to be of the tapered variety). I remove the lock pin, unscrew and remove the bottom plate, pop the top cap off, and then position a roller thingamabobber from a previous brake change into the hole and give it a good thump and the pin usually drops right out. Of course in order to get the clearance to do that, I have to remove the brakes and hub assembly...tried it the first time without removing everything and wasted more time beating on the stupid thing than it would've taken to remove and reinstall the parts I was working around...and STILL had to pull them before I could finally get that stupid pin to drop. Now, I don't even attempt to knock the pin out until I've made room to work. 2 Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!

Ezrider Posted February 18, 2018 Author Share Posted February 18, 2018 yeah mine has straight pins rather than taper, but in theory removal is exactly as you described. i think the taper pins are a much better way to do it than straight pins kinda like a tie rod end. as once you get the slightest movement they will fall out. problem comes in when they have been installed on the truck for god only knows how long and road grim water salt ect. the pin seizes solid into the axle eye.

RowdyRebel Posted February 24, 2018 Share Posted February 24, 2018 You know, though, if it didn't happen on video it may as well have not happened at all. You've got a good cover story, but without video I'm thinking the Mrs found a greasy truck part in one of her clean kitchen appliances and introduced another kitchen utensil (rolling pin perhaps) to your noggin... ...just sayin'... 1 1 Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!

Also good idea on how to make Harbor Freight tools more useful. not as dedicated as it may seem....lol when i got smacked it was 4-5pm i pretty much picked up for the day and went home didn't get back after it till the next morning. had it been earlier in the day i might have just kept going. but i certainly didn't feel like doing any more work for that day.....lol enough years ago that i don't remember how many years ago it was. i pulled in from the road and picked up a slow leak in a steer tire on my way home. i decided to fix it before i went to the house rather than potentially have a flat steer tire when i came back out the next morning. so being in a hurry and wanting to go home. i just nosed the truck in the shop busted the steer tire apart. patched it then before i put it back on i decided i better pressure wash the mud and grime off the rim before i put the tire back on. wheeled the pressure washer over grabbed the pull cord and gave it a sturdy pull. when i did that i racked my elbow into a bracket on the roll up door. and laid my elbow open pretty bad. then im standing there and as im realizing its going to take a trip for some stitches i look around and realize i cant leave. because i cant close up the shop due to the truck being half way in the door. and i cant move the truck because it doesn't have a steer tire on it. so i remounted the tire backed the truck out of the door and then went to the hospital for stitches. when i came back the next day it took a bit of pressure washing before it no longer looked like a crime scene...lol but that was more a choice of do i want to suffer threw mounting this tire or possibly come back to a shop with no tools in it. after i was done pressing the kingpins out i welded some legs on that press and made it a bench top press. i have another stand up but i didn't want to cut it up for this project but it always ends up burred in the corner. i recorded turning it into a bench top press and had planned on including that in this video but this one got kinda long just in what i covered on it so it got left out. maybe it will get included somewhere else or become its own video or maybe end up in the scrapped footage folder i dunno yet....lol 9 hours ago, j hancock said: Good video. PLEASE put some safety glasses on! yes sometimes i get a little lax on the safety gear. im not sure exactly where i cut the footage but when i first started pressing the kingpin out and there was some tension on the press i put a full face shield i was also standing back and off to the side pretty much completely out of frame. then as soon as it started moving and there wasn't as much force on the press i took it off. i think i was also wearing it when flap disking the axle and spindle. i generally will not do any thing with a grinder or a welder without eye protection (metal in the eye or flash burn is not fun ask me how i know....lol) when i was trying to remove the first one i did have a pair of normal safety glasses on when i got smacked in my face. and i have not found them sense....lol safety gear is certainly somewhere i could/should pay more attention to. 10 hours ago, mackey58 said: Nice video hope ya dont get hurt anymore gonna check out ur YouTube thank you. i hope to avoid future injury's as well.
