Time for re-assembly ( Hydraulics)

[Billie R. Smith]

49 8n 6v front dist.Well its been a long time since I started this project ,but I think i'm ready to put it all back together.I removed the lift cover and replaced the piston and ring,as well as a few other parts that I broke ,and with the help of the Zane thang jig I feel confident that its all ready to be put back on.Pulled the pto shaft and replaced the leaky seal,and dropped the hydraulic pump. Surprised to find it actually quite clean.No scraping needed,just a quick kerosene flush.Removed ,cleaned and inspected all the valves and installed a new relief valve just to be safe.So before I put this puppy back in I need to burden you with a couple more questions.Please bear with me.

I did not remove the valve chambers from the hsg. Do I really need to?

Is there anything in there that I need to inspect?(other than the valves)

Do i need to remove the scotch yokes ?

What are the leather gasket,seal,washer,things for?I wound up with 5 new ones .

Its been at least a 2 year project for me due to time,and financial constraints. All you guys have been a tremendous help. This whole thing just seemed so intimidating at the start.It really ain't rocket science when you have the right people to grill for answers. Thank you one and all.

Pistons, cylinder walls, valves, valve seats, valve springs.

All that stuff looked good.

Billie - JMOR's list is the things you will see only if you pull the chambers and scotch yoke. You could put it back and try it out but if looking for like-new performance, you may be dropping the pump again.

The lift ram can use either a 3 ring or a single ring piston. Sounds like you have the single ring piston, in which case the leather washer goes in the same groove as the o-ring, on the side closest to the open end of the ram cylinder. It's a "backing" for the o-ring. Other parts will be unused.

Better backup washer for the NAA type piston (neoprene type, not leather).

BTW I just put all my 2N hydraulics back together!
I did the external pump hookup for live hydraulics.

Let me know if you want to hear some war stories.

I would not pull the valve chambers unless you see some severe damage to the pistons or yokes.

You possibly could run into the same fix that the guy down the page has where the chamber gaskets were too thin and not the pump can't be re installed.
