Fastduramax Posted May 25, 2023 Share Posted May 25, 2023 Anyone know if a direct drive C102 hydraulic pump will bolt up to a 12 speed Mack rear mount PTO or know of one that will ? These drive shaft driven units suck ass ! Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/ Share on other sites More sharing options...
JoeH Posted May 27, 2023 Share Posted May 27, 2023 You need to check the spin direction of the PTO. If it's a PTO on the back of one of the counter shafts then I believe it spins opposite of typical pumps. You would need to talk to a hydraulic component retailer to check your pump on your setup. Verifying direction of rotation is important. As is communicating it to the pump shop... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-531993 Share on other sites More sharing options...

Not trying to hyjack this post, but my personal beef with them is the extra space they take on an application that's space limited. And the added moving part (driveshaft), which is kind of a moot point, but it's always nice to eliminate extra moving parts when possible Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-532017 Share on other sites More sharing options...

Fastduramax Posted May 28, 2023 Author Share Posted May 28, 2023 Floater is correct, any driveshaft and universal joints suck especially if not necessary... Gallion installed the original dump body on my truck and mounted the pump at to much of an angle, 2 years out of a set of universals and it vibrates like hell, so choices are refabrication or a "piggy back" pump, best choice is the latter IMO.... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-532055 Share on other sites More sharing options...
Full Floater Posted June 3, 2023 Share Posted June 3, 2023 I have yet to speak with a drivetrain shop to see what they might know of, as to what's out there or what can be made.

Fastduramax Posted June 3, 2023 Author Share Posted June 3, 2023 Thanks Donny but that is a confusing reply.... I have a Mack rear mount PTO on my 12 speed, the only question Floater and I have is there a C102 configuration that will mount to the Mack PTO so we can eliminate the C101.... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-532375 Share on other sites More sharing options...

MACKS Posted June 3, 2023 Share Posted June 3, 2023 Rear mount pto to remote pump is your only option,get it set up right keeping the drive shaft as short as possible,still way better than a side mount.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-532421 Share on other sites More sharing options...

Thanks. Curious as to what is better about the rear mount? Is it a stronger or more reliable location to mount the PTO, rather then the side?

Full Floater Posted June 8, 2023 Share Posted June 8, 2023 I just bought another parts truck, with a 6 speed and a side mount with a driveshaft pump. Never actually seen a side mount on a 6 speed. Haven't got the number off of it, just something I noticed Quote Link to comment https://www.bigmacktrucks.com/topic/72888-direct-drive-dump-pump/#findComment-532651 Share on other sites More sharing options...

With the rear mount u don’t have to put the Tran in gear with splitter In neutral ,it works in neutral and also when in gear your body will go up just as fast even if your in first gear,great for running out loads..
