Mark T Posted Sunday at 10:55 PM Share Posted Sunday at 10:55 PM That pump is a Vickers. I would think parts for it are still available or a suitable replacement is. The control valve ? That might be a problem. Are you sure it's a Ross valve ? The cylinder ? would seem a good hydralic place could do something with that. Wouldn't surprise me if a different make control valve would interchange with your's. Reservoir, a newer Nelson wouldn't be a very dificult swap. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591662 Share on other sites More sharing options...

It says Ross on the cylinder.I have the original paperwork for the truck and it says nothing about the power steering. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591663 Share on other sites More sharing options...
hicrop10 Posted Sunday at 11:46 PM Author Share Posted Sunday at 11:46 PM I found in the paperwork that it has a Ross Hydraulic system for the power steering. 49 minutes ago, Mark T said: That pump is a Vickers.

Solution Mark T Posted Monday at 12:19 AM Solution Share Posted Monday at 12:19 AM It looks like a power assist system on it. The pump is a Vickers. That just supplies the system with pressurized oil. The valve in the picture is the control valve, then I'm assuming it has a cylinder attached to the tie rod underneath it. What are you trying to repair on it ? 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591666 Share on other sites More sharing options...
PMC Posted Monday at 02:48 AM Share Posted Monday at 02:48 AM (edited) That's a fairly simple system to rebuild. The control valve uses standard O-rings. The hydraulic cylinder has a couple cast piston rings like an engine and orings for sealing it. I got my rings from Hastings and am pretty sure i have some extra.

mattb73lt Posted 23 hours ago Share Posted 23 hours ago Could it be a Garrison assist system using a Ross piston? The control unit looks like the one I installed on my B73. I had both units rebuilt by a local hydraulic shop, made up the lines myself. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591729 Share on other sites More sharing options...

HarryS Posted 8 hours ago Share Posted 8 hours ago I thought the valve looked like a Garrison also. Here is a picture of the Garrison I took off the B-61. Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591770 Share on other sites More sharing options...

mattb73lt Posted 4 hours ago Share Posted 4 hours ago That's the same valve body I have as your's and HarryS'. I'll have to look through my paperwork, but I made copies of the installation and plumbing routing from a maintenance manual I borrowed to install it. I'm going off memory, I recall it did say Garrison. As for the Ross unit, like Sheppard, that was a power steering box rather than an add-on assist unit. I've seen some that have a Ross Power Steering logo horn button on various make trucks. I know there's some casting numbers and IN/OUT markings on it, maybe a part or assembly number, but I don't recall seeing Garrison or an ID tag on the valve body. My pump was a Vickers unit I sent out for overhaul that had an integral reservoir bolted on top of the pump. I just went through my photo archives and I took copies of the plumbing from what looks like a Mack maintenance manual. I have a pic of the rebuilt and installed pump. The only picture I have of the valve body was from the donor truck, covered in grease and dirt. But, that picture also shows the steering are limit stops that I grabbed and installed, too. I do have a picture of it hanging up after I painted it. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76422-need-help/#findComment-591780 Share on other sites More sharing options...
