Power steering issue on a gas converted m1028.

[alex33072]

I put an SBC 350 in an m1028 and the power steering will not kick in until I rev up the engine. I'm wondering if I need to put a smaller pulley on the power steering pump or what might be the issue. I put a rebuild kit in the pump before I installed it. My thought is that it may be turning too slow for the vanes to kick in or is there possibly a blockage somewhere? Any thoughts would be appreciated. Fluid is all new, belt is tight.

Perhaps there may be air trapped in the system. I would try to cycle the steering from lock to lock with the axle on jackstands.

Still hydroboost? Is your foot hard on the brake pedal?

Shouldn't have to change anything. mine was converted to SBC and no issues...... Sounds like a pump issue

Did it once but I'm going to try it again in a couple of hours. I'll post the results.

Yes still hydroboost. I'll try it again with my foot off the break in a couple of hours. Why would that make a difference?

Did this again. Didn't seem to help. Thanks for the suggestion.

I just noticed I should be using dexron to in the pump. I had O'Reilly's power steering fluid in there. Will that make a difference?

Problem solved. When I rebuilt the PS pump at engine install, the pump kit purchased was for a gas pickup. Got the correct diesel kit and all is now good. Thank you all for your suggestions and help.
