wilbur Posted August 1, 2015 Share Posted August 1, 2015 I have a 2000 CH with Eaton rears. I am looking to shave some weight to help with payload. My idea is to remove the front carrier with the power divider and replace it with the rear carrier. This will make the rear axle a floater. I will make some adapters to mount a trailer lube cap on the axle flange studs an cover the front of the carrier housing with a piece of thin aluminum. I will also add a valve to just drop the air in the floater axle to put all the weight on the front drive axle. This I think will help on unlevel ground. I dont go off road I just haul from the Quarry to an Asphalt plant. Im thinking this will lose around 800# Carrier with power divider and 2 axle shafts.Your thoughts and opinions are Appreciated.

theakerstwo Posted August 1, 2015 Share Posted August 1, 2015 Forget the alummin ideal for a cover on the rear housing because the carrier bolted in there is the housings strength.I have seen many carriers loosen the mounting bolts from the movement of the housing flexing and grease leaking.Also you will now be put full torque thru one ring and pinion where two was designed to carry the power.But I have seen a lot of guys do this with out problems but for 800 lbs I would not take the chance.And I am no expert but have read a lot of books on trucks.

wilbur Posted August 2, 2015 Author Share Posted August 2, 2015 I found Spicer makes a kit for this but unable to post the link Why? Quote Link to comment https://www.bigmacktrucks.com/topic/41183-for-the-experts/#findComment-298782 Share on other sites More sharing options...
Nobody454 Posted August 2, 2015 Share Posted August 2, 2015 i have towed a bunch of Conway kw tractors that are set up just like that. the rear axle has a normal housing but no guts or axles. has a flat plate bolted onto the front of the housing and dummy caps on the ends of the axle tubes Quote Link to comment https://www.bigmacktrucks.com/topic/41183-for-the-experts/#findComment-298783 Share on other sites More sharing options...
Keffer inc Posted August 2, 2015 Share Posted August 2, 2015 Hey wilbur, where you located? I have a rear rear spicer in my truck that's in good shape, front rear needs new yoke bearing, but for your idea, you could buy a used trailer axle and bolt that in place of the rear rear, and use my rear rear in the forward position. I'm thinking of trying to find some mack rears for my truck. My ratio is 3:54 Quote Link to comment https://www.bigmacktrucks.com/topic/41183-for-the-experts/#findComment-298784 Share on other sites More sharing options...

Joe Ditchkus Posted August 3, 2015 Share Posted August 3, 2015 Roadway Express used that concept for years Hendrickson Walking Beam Suspension with front driven only last axle was a tag not a empty pumpkin like you want to do. Even with the Hendrickson Walking Beam they would get stuck on level ground with a bit of snow with a little imperfection of the ground. Forget about going p snow covered hills without jewelry.Joe D. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41183-for-the-experts/#findComment-298808 Share on other sites More sharing options...
Timmyb Posted August 3, 2015 Share Posted August 3, 2015 But the front diff has a through shaft where the rear one doesn't. So you will have a hole in the front housing that would need covering.

theakerstwo Posted August 3, 2015 Share Posted August 3, 2015 Many trucks have a single drive with a tag but most are set up with a 40/60 weight ratio plus the single axle carrier is not the same as a rear from a tandem drive.

HeavyGunner Posted August 3, 2015 Share Posted August 3, 2015 Don't you have uneven, loose and possibly muddy ground to get around at the quarry? From the couple of tandems I've seen on farms around here with a dead axle there's no way I would give up power to both.

Lmackattack Posted August 3, 2015 Share Posted August 3, 2015 Thinking you will need good tow hooks if you go this way. Never seen a good tandem rear on/off road truck with a dead axle.

Maddog13407 Posted August 3, 2015 Share Posted August 3, 2015 agree. will be about worthless with one driving axle and why waste the time doing it. years ago when the length laws changed and everyone tagged their single axle it made them a pos to get around with Quote Link to comment https://www.bigmacktrucks.com/topic/41183-for-the-experts/#findComment-298868 Share on other sites More sharing options...
wilbur Posted August 3, 2015 Author Share Posted August 3, 2015 I did some more checking,an for it to work I will need a different heavy duty front carrier. Thats why spicer says only a 400# weight savings. Its just too expensive for me to only gain $9.00 a day. Thats why I shy away from super singles. I would like to thank everyone for the help. If you have any ideas that are cheap to save weight let me know. Thanks Wilbur. If anyone ever comes to the Thornton Quarry give me a hollar Im there 16 times a day. I have a white ch with silver flames pulling a trail king aluminum.
