Great site but still no blow up of the head their is a photo of the drawing i need lol so close but so far

Hi Bob,

The picture of the drawing is all I have. I managed to find it late last night. I was going to send it to you today.

I replaced the bearings in my knuckle head a couple of years ago. From memory the bearings were considerable more expensive than a metric equivalent.

If I had to change them again I might consider re-engineering the casting to take metric bearings.

Out of interest do you have a link to the bearings you purchased?

Steve.

Hi Steve i got the part numbers from a post on here somewhere the 2 thrust races i got from Ebay The MS9ACD was ebay and so was the LS10ACD i did google them but a big variation in prices

If I remember rightly the horizontal drive has bronze or oilite? bearings & the MT shaft has 2 bearings in it. 1 at the bottom which is held in place with the cover & the one at the top is held in place with a split screwed washer (the type you put a screw in so it doesn't come loose I don't know what you call them) there are no shims in there. You have to put the bearings on the shaft first and then slide the whole thing into the head.

your old bearings should have numbers etched onto them so you can identify them like that if all else fails

regards

Paul

Thank you for that Paul i have found the 2 bearing numbers and the to thrust bearing one and have ordered them i now need the number for the Oil seal and i think we are sorted.

Hi Bob,

Which vertical head are you interested in? S type or knuckle head?

Steve.

Hi Steve not sure the difference between S type or knuckle but its just the small one it has no quill on it if that makes sense.

i hope Paul will have the drawing i need.

Hi Bob the oil is supposed to drain back to the tank by a hose and passage ways. The system loses quite a lot of oil to drainage and you should clean all the ways and pipes as they get clogged with dust and grease like deposits especialy from the catch trays in the casting on either side inside and the steel pipes from them to the tank. If you disconnect the cylinder on the table traverse you will find that with help, three people, you can lift off the bed, carefully to not bend the rod, and you can get to other oil drains from the cylinder as well. Find something to put heavy bed on befor lifting. You can run the hydraulics with table of and see where oil is running to but operating traverse by hand. If you need any help just ask.

David

what do you mean by disconnect the cylinder? David

13/03/2019 08:31:41

sorry for late reply to you all been so busy with work but i am very grateful for all the comments looks like a day taking the bed off and doing a big clean glad i did not clean out the tank yet as i had planned.
