mrsmackpaul Posted August 24, 2023 Share Posted August 24, 2023 Rear axle, jack it up, grease up a long flat bit of wood, undo the nuts hold the axle, give it a whack and it should come loose Slide the axle out Back the brake off fully Lower the truck so the wheels are just touching the greased bit of wood Undo the bearing nuts Slide the hub, drum and wheels along greased up board as one whole unit Then pop the seal out, remove the grit guard if fitted and source parts To fit is the reverse Front hub I reckon you pop the cap in the center Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537616 Share on other sites More sharing options...
mowerman Posted August 24, 2023 Share Posted August 24, 2023 Unless you have a pallet Jack and a helper or an engine crane you’re better off to take off the tire,and rim otherwise everything is too heavy together good luck bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537618 Share on other sites More sharing options...
mowerman Posted August 24, 2023 Share Posted August 24, 2023 That’s for the front the rear yes, Paul is pretty precise on that greased up board as the ticket… again if you have a pallet jack it’s a lot easier for the rear rear or the front good luck bob 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537619 Share on other sites More sharing options...

I’m gonna pull the wheels, then, I’m gonna pull the spider, right? Then I can slide the drum off? Just making sure I have a decent plan before I go ahead. Also, how do I get grease into these front wheel bearings? This is the old grease cap, right? Do these covers unscrew? Anyone going to the truck show in Bolton, MA this weekend? I do believe they are a screw on cap, terry 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537628 Share on other sites More sharing options...
Craig N Posted August 24, 2023 Author Share Posted August 24, 2023 Man, I can’t thank you guys enough!! Thank you. This information is such a valuable resource. I used to do wheel seals 20 years ago on the R models I was driving, but it’s been a while for sure and I know these are different. I remember having to hit the axle with a sledgehammer for it to pop out.

mowerman Posted August 25, 2023 Share Posted August 25, 2023 I forgot to mention, even if you use the grease Paul suggested, which is a fabulous idea. You should have somebody helping you because the duels with everything connected are very heavy. Good luck….

I used to do wheel seals 20 years ago on the R models I was driving, but it’s been a while for sure and I know these are different. I remember having to hit the axle with a sledgehammer for it to pop out. definitely hit the axle in center. I had a 5/8th die welded to a large nut which I put a socket for the sledge hits that missed the axle and hit the studs, I see everyone saying a grease board for sliding the complete assy.I used a steel/tin plate for the sliding . board may have a tendency to not slide as easy. important thing is do what is better for you. if need to disassemble wheels separately then that's the way to go. yrs of grease board wheel sliding and other feats your back will let you know every day. even for removing tires I use a hand truck . 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537649 Share on other sites More sharing options...
Popular Post terry Posted August 25, 2023 Popular Post Share Posted August 25, 2023 I was a owner/driver a mack dump for 30 plus years, the wheel dolly was the best investment for pulling duals, nothing to it for one man, and alot easier to align the inner bearing on the spindle, and not hitting new wheel seal. terry 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537657 Share on other sites More sharing options...
mechohaulic Posted August 26, 2023 Share Posted August 26, 2023 wheel dolly is definitely the way to go. for someone having one unit which may be a show truck only , the wheel dolly is an expensive investment. find one to borrow . worked for a fleet of 4-5 units ; yrs I did the grease technique ; finally the "frugal "(CHEAP) owner invested in a wheel dolly. worked the best. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537692 Share on other sites More sharing options...
mechohaulic Posted August 26, 2023 Share Posted August 26, 2023 seems this topic went off topic ==I DIDN'T do it !! LOL pulling injectors ended up on wheel seals . guess it's ok; same truck 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537696 Share on other sites More sharing options...
mowerman Posted August 26, 2023 Share Posted August 26, 2023 Well you know I don’t know about you fellas but Home Depot here rents just about anything engine crane would be the ticket. I’m fixing to buy one shortly myself I am pissed harbor freight wanted 179 now it’s $100 more after.. but they are a lifesaver. He could also use one of those not that much to rent one wheel dolly. Yes, of course that’s the ticket, but as you mentioned. Ca Ching ca Ching and as an individual, how often would you need it? 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537699 Share on other sites More sharing options...
mowerman Posted August 26, 2023 Share Posted August 26, 2023 I forgot to mention in that last paragraph before Covid. The engine crane was $100 cheaper. Auto spell doesn’t want to work right anymore on this phone. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/24/#findComment-537725 Share on other sites More sharing options...
