Massey Ferguson 175 3-Point Hitch Won't Lift: What I've Learned About 100 Series Hydraulics

This video starts in the middle of my own hydraulic horror show as I attempt to reassemble a 1964 Massey Ferguson 175 that I've split to remove and rebuild the hydraulic pump. I reinstall the hydraulic lift pump and auxiliary hydraulic pump. I adjust and reinstall the top cover. I put everything else back on successfully and run the bush hog to test everything.

If you want to know more about what lead up to this video, you can view the thread I started about the problem on the Yesterday's Tractor's Forum at: https://forums.yesterdaystractors.com...

The Tractor Forums thread where I found the tip originally shared by Big Dean about the 3/8" for setting up the top cover instead of the special service tool MFN-970 and anything that'll hold the arm extended instead of wedge tool MFN-163: https://www.tractorforum.com/threads/...

The reproduction special service tools can be found from VL Churchill & Co. LTD on their website at: https://vlchurchill.co.uk/

The carbide scraper that I mention is Lisle Tools 81810:
