Craig N Posted November 26, 2022 Author Share Posted November 26, 2022 Different rear axles between the two trucks too Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/14/#findComment-516096 Share on other sites More sharing options...
Joey Mack Posted November 26, 2022 Share Posted November 26, 2022 the difference between the drive axles is.. The one with the cone shape is a cap, and the axle is a seperate shaft, and there may still be a seal in the center of the hub to keep oil on the inner bearing and grease on the outer bearing. I have removed that seal and made the whole hub an oil bath type.. The other flat axle cap is a flange and the axle shaft and cap are one piece.. Both seal with good quality RTV, when put back together..

Craig N Posted November 26, 2022 Author Share Posted November 26, 2022 Thanks guys! It’s been over 15 years since I took anything like these apart. I did axle seals on a 74’ R model and an 81’ R model back then. I remember hitting the center of the axle with a sledge hammer to get it to break loose.

mowerman Posted November 26, 2022 Share Posted November 26, 2022 I think that’s too loose in the keepers that’s why the end of the axles are all beat to hell 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/14/#findComment-516102 Share on other sites More sharing options...

Popular Post Freightrain Posted November 26, 2022 Popular Post Share Posted November 26, 2022 B61"3" denotes a turbocharged 673. Front Axles difference: Both are grease. I think they are different weight axles, thus different caps. 3 Quote Larry 1959 B61 Liv'n Large......................

Mark T Posted November 26, 2022 Share Posted November 26, 2022 1 minute ago, Craig N said: Ahh, nice. Learn something every day. Thanks The one with the "cone" is a full floating axle. Those you don't hit when you take the six nuts off of it. The center of that cone is only a soft plug. The "cone' or drive plate is splined to accept the splines on the axle (just like in carrier on the side gears) the other type with the flange ( flange and axle shaft one piece ) is the ones you smack in the center to get out. Usually the wedges behind the nuts don't like to give up easily on older stuff and they can be frustrating to get out. I agree with the others , the front ones are likely from different size axles (weight and bearings) So likely not much of any of it will interchange between the two trucks. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/14/#findComment-516110 Share on other sites More sharing options...
