Crank lubricator fouling regulator rod

Post  IanR on Tue 30 Aug 2016, 11:28 am

Just wondering if anyone else has had this. I've just fitted the regulator lever an rod and found that the lubricator cup on the crank is hitting the regulator rod. Any ideas of how to get round this?

I am 99% sure I read in one of the stages that the larger cup was too big. I'm not far on enough to tell you if I have the same problem. Did you get x5 small cups with kit 20/21?

Thanks Jim,

No, no oiler cups in kits 20/21. There was 5 in kit 19. 3 for the eccentrics and the other 2 are for the wayshaft bracket and the top slide. I'll have to call STW and see if they can supply a smaller one.

Jim may be right. I am only on kit 17, so have not had regulator rod yet, but looking at your phot and comparing it, your cup appears to line up with outside of the brass bearing, whearas mine is inside. Unless thats the photo perspective. If its any help
the cap on my oiler is 12mm across. Mike

Thanks Mike. The perspective in the picture is a bit misleading but the cap on my oiler is 12.7mm and the oiler itself is 12.5mm. That might be just enough to make it touch the rod. I'll have to get in touch with Steve. I guess they're all down at the GDSF at the moment.

It looks as if I'm going to be in the same situation then. You've measured a bit more accurately than me.

Hi there
Maybe it is my eyes but should the rod not be be parallel to the con rod? Could the rod not be moved over, perhaps by using a thinner locknut?
All the best

I think the regulator rod is pretty well parallel with the con rod as far as I can tell looking at it. I've emailed Steve to see if a small cup is available.

Thanks

If you get no joy I'll pop home at lunchtime and take a look at my machine and compare.

Hi all,

I've just had this reply from Steve. Might be helpful to others:

I have to admit to a flaw in my design. What you've got is exactly as it should be, but you're the first person to point it out to me. Strange really as the design has been around for about 10 years and we must have supplied well over 200 of them! Sometimes customers get over the problem and just forget to let me know.

I think the easiest way around the issue would be to slot the holes in the spectacle plate to move the regulator bracket over by a suitable amount. Many of the full size engines had a joggle in the regulator rod, I don't think you'll need to do this but that will depend on how tight the various clevis pins are.

I've altered my drawings, so at least the next batch produced won't have the same issue.


I'll slot the holes in the spectacle plate and post more pictures when I've got it OK

Thanks
Ian

I widened the holes by not much more than 1mm and the cup and the oiler just miss each other now. All bolted up now so not really much to show in a picture.
