Lozzatron Posted January 5, 2023 Share Posted January 5, 2023 G'day I'm checking out a 2003 Titan with hub reduction Renault diffs, problem is, I cant find anything on google, not a scrap of info, regarding these diffs. I can find a couple other similar trucks for sale with the same diffs but that's about it. At this stage I have no part numbers until I go see the unit. Has anyone got an opinion, any technical info, a manual or even a brochure on these? Cheers, Laurie.

Mackpro Posted January 5, 2023 Share Posted January 5, 2023 I looked at all the Titans here in the states and they use the Mack 202/203 series and the 95/96 series carriers or the Meritor RP/RD/RR 23164 carriers . I looked at the hub variations too and nothing wild and crazy. I know things down under vary greatly than here. Is is possible to get a VIN number or whatever ID number used there? I can look into it specifically that way. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70977-mack-titan-renault-deep-reduction-diff-info-or-lack-there-of/#findComment-520077 Share on other sites More sharing options...

Lozzatron Posted January 5, 2023 Author Share Posted January 5, 2023 Thanks for the tips so far, I'll have more info soon, carrier part numbers etc, I have to drive 7 hours to see the truck so hope to head out there next week. Based on info above I found this parts supplier that may or may not help future searches: https://bisonparts.co.uk/product/renault-kerax-1997-2013-rear-wheel-hub-only-19146 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70977-mack-titan-renault-deep-reduction-diff-info-or-lack-there-of/#findComment-520103 Share on other sites More sharing options...
Hayseed Posted January 6, 2023 Share Posted January 6, 2023 Laurie, I'm pretty sure Mack Australia use SISU Hub reduction Diffs in the Titan...!

Mark T Posted January 6, 2023 Share Posted January 6, 2023 There was a Titan at the local dealership here years back. It had planetaries . I remember it had aluminum 9 inch wheels and 315s ( some special wheels ) I remember the end was planetary but not like the giant ones I'd seen in Canada that had way bigger ends. That particular truck also had an Allison with a 4 way behind it. Used for moving windmill blades.

Lozzatron Posted January 13, 2023 Author Share Posted January 13, 2023 I went out and had a look but she was let go a bit too far for the cons to outweigh the pros. Thanks Hayseed, there what we thought too! The diffs were 5.23:1 Renault pmr2345's. 80km/ph at 1800rpm, top speed of 85km/h, unless I missed top, which I really looked hard for... I was in it but it didn't feel like it, put that down the the diffs. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70977-mack-titan-renault-deep-reduction-diff-info-or-lack-there-of/#findComment-521115 Share on other sites More sharing options...
