I will share the drawings for the gaskets as soon as we've tested them :LOL: The (old) valve block cross saddle gasket is 0.4mm Flexoid - It says 0.4mm on the sheet and measures 0.28-0.35 with a micrometer. I've got a new sheet of 0.4 Flexoid which comes in at 0.37 on the micrometer. I will use...

I am in the process of cleaning everything up - then, I will take photos of everything before reassembly. The gaskets are all made from paper. The valve block gasket which seals the block to the cross saddle is of the Flexoid variety. The gaskets between the end plates and chambers of the valve...

Valve block out and in pieces. (Un)fortunately, no pistons were stuck as I initially suspected. So.. clean up and rebuild begins soon.

My next question involves removing this cross saddle. I see 2 hoses connected to it if I shine a light past the valve block, which I'm assuming is the hydraulic oil feed (and drain?) lines to the cylinder block. I see yours are plugged in the image above. But I don't see a way of removing this...

Once the grub screw is removed, the shaft should slide out, right? I don't see anywhere to tap it out from behind, but don't want to grip the end and potentially damage it - yes, mine feels wedged in there. Any advice on removing this?

The cylinder blocks weren't going anywhere with those dowels in place. After noticing that they were threaded, we jumped onto the lathe and just machined a small tool to help us pull the dowels out. May not have been the right way, but they eventually came out to say hello. The cylinder block...

Unfortunately, I have not fixed the fault yet. I pulled the table off before going to remove the 8 bolts holding the cylinder block assembly down (pg 27 in my manual). It wouldn't budge, and that's how it's been for the past 2 months. Other work also got in the way! I'm back now, so let's see...

Rather late, sorry! :oops:

Deema, as per your suggestion, I did some reassembly and powered the machine. The first thing I noticed was a leak at the valve block gasket - behind the throttle handle and reverse lever. Probably caused by my fiddling. The table only moves from right to left (when operating the machine)...

I had a similar thought about the gaskets and intend exploring that option (if necessary). Shipping to SA is always a pain. Can you please elaborate on the issue with the ram? Or link to a thread/ forum. My Googling isn't yielding much. If that is indeed the issue, I have probably disassembled...

I will try to document as much as possible. Seems like the next step is to pull the cross saddle to get to my hidden bolts. Also, thanks for the schematics. Quite a bit better than the Illustrated Spare Parts Catalogue I have to work from :LOL:. (See below for comparison to 18. Valve Block)

Thank you for the link. Luckily I found it before tearing into our machine, so I certainly felt like I had a helping hand. (Thanks Deema!)

Hi everyone! I'm new here - located all the way down in South Africa. I'm hoping that I can get some old machines back up and running with some assistance from this forum. The first machine in question is a Jones and Shipman 540 surface grinder. We acquired it roughly 3 years ago, knowing very...
