RMweb Gold JohnR Posted September 21, 2021 RMweb Gold Share Posted September 21, 2021 I just dont seem to be lucky with my pointwork. After a summer break while I regained my "mojo", I've fired up the layout today, only to discover that two of my points are not working correctly. At first I thought it might be some ballast having fallen in between the point blade and stock rail, but I've cleaned it out and it still happens. The motor seems to struggle the throw the point, and moving the point manually reveals its a little stiff, but it does manage to throw. I have a powerful CDU, and all point motors were working well up until my break a few months ago. Link to post Share on other sites More sharing options...
Chrisr40 Posted September 21, 2021 Share Posted September 21, 2021 Hi, I have had similar problems in the past. Usually a quick squirt of wd40 in to the motor and operating the motor by hand a few times frees things up. Just don't use wd40 for anything else or you will never hear the end of it.

The point motor is a SEEP (I'm beginning to regret going for them) - it seems to move freely enough by hand - do you mean I should lubricate the throw bar that slides between the 2 coils?

RMweb Gold john new Posted September 22, 2021 RMweb Gold Share Posted September 22, 2021 From experience in the past I would avoid WD40 (Certainly the standard type) but use one of the dedicated electrical cleaners. 1 Link to post Share on other sites More sharing options...
RMweb Gold beast66606 Posted September 22, 2021 RMweb Gold Share Posted September 22, 2021 It's possible the throw of the motor is not / no longer aligned with the tie-bar, maybe the boards have swelled during your break ? - remove the motor and test the point, if it moves freely it's the motor alignment, if not it's the point. 1 Link to post Share on other sites More sharing options...

I would also avoid WD-40 as it dries out to become a very thick sticky goo and eventually goes hard. 1 Link to post Share on other sites More sharing options...
Davidl66 Posted September 22, 2021 Share Posted September 22, 2021 I agree with the alignment comment. Slackening the screws holding the point motor to the baseboard slightly so the seep has a bit of play in it may help. Link to post Share on other sites More sharing options...
RMweb Gold JohnR Posted September 22, 2021 Author RMweb Gold Share Posted September 22, 2021 I'm not totally convinced it is point alignment - when fitting the SEEPs, I used alignment mounts, which cured the initial problem I had. Since then, the points have worked perfectly. However, my fiddling about has resulted in one of the feeds to the point motor coming adrift, so I will have to turn remove it anyway.

I'd investigate the stiffness. You may find that something is binding as the switch blades move. Prime candidates include the switch blades themselves on the underlying sleepers or the tie bar against the adjacent sleeper/connectors on the outslde of the rails. A little bit of filing or scraping in the right place might deal with that problem. Yours, Mike Link to post Share on other sites More sharing options...
Michael Hodgson Posted September 22, 2021 Share Posted September 22, 2021 Does the point still have its over-centre spring? Link to post Share on other sites More sharing options...

Definitely don't use WD40 on the plastic on points, it will cause cracking of the plastic and lead to failure. Might take a year or two to occur, just when you think there is no problems using the stuff.

LNERGE Posted September 23, 2021 Share Posted September 23, 2021 The compression of the spring can be atered by moving the bit held by the two metal clip thingies, carefully. Link to post Share on other sites More sharing options...
