philwaters Posted April 16, 2009 Share Posted April 16, 2009 Just completed (needed to get some oil) and have a working jack again . Got some new seals, including the inner small one (as mine was only about 3/4 complete). For reference the o-ring sizes I measured were: 2 x 30mm Outer diameter, 3mm thick 1 x 18mm outer diameter, 2.5mm thick Just as an aside, should anyone else find this thread, I didn't need to do some of the instructions, I just did the following: *arrowright*Removed the bolts holding in the main block (4 each side) *arrowright*Removed the 2 circlips holding the lower arms to the platform *arrowright*Removed the split pin holding the piston to the arm *arrowright*Slackened the 26mm nuts, the cross member and front roller bolts to allow the side plates to move a bit to allow the main block to be removed. *arrowright*Then I placed it in the vice as mentioned in the instructions linked to above. Mainly because on my jack I can't un-bolt the yoke (point 4) - it is a press fit into the side plates. Oh, and make sure to fit the release hex drive pin back into the yoke location - I forgot and had to drop the block again to re-fit. 🙆🏻 Phil Waters Link to comment Share on other sites More sharing options...
Pooh_R Posted October 27, 2011 Share Posted October 27, 2011 My jack needs re-sealing. I'm looking at my kit of standard sized O-rings and am wondering if any of them are the correct size. Please could someone advise if these are R18 O-rings? (23mm id with 3.6mm cross section). see here for a list of standard sizes. I assume the smaller one is R11? Or, are they non-standard sizes? thanks ! Link to comment Share on other sites More sharing options...
Roger Ford Posted October 27, 2011 Share Posted October 27, 2011 According to my post here you need 2 of 23.5mm x 3.5mm, and 1 of 13mm x 2.5mm That's how they're listed in my Machine Mart set. Don't know how that corresponds to your R numbers (aren't those for Imperial O-rings?) Oh, hang on, post before says they're F19 and F9. Again, don't know how that relates to R numbers.
