Don't quote me on this, but usually a motor either runs or it doesn't. Once the windings break down the current starts to jump the gap of the break, eroding the edges of the fracture until the wire is completely broken and open-circuit, or just short circuits to adjacent windings. Either way, the motor stops turning. If it turns but only slowly I wonder if the bearings have run dry? After 40 years and more with likely no attention, the grease will probably be well on the way to setting solid. Easy test is to squirt in some WD40 if you can, or maybe run a few drops down a thin screwdriver into the general bearings area, then leave it for a few hours to seep into the bearing race. If that doesn't improve things, then it could be worth removing the motor for a closer look at the bearings (if the motor's shot it'll have to come out anyway). If you think it can be salvaged, you could try running ACF-50 into the bearings. This is like WD40 but much more of a longer-term oil and less of a deep penetration solvent. It will get absorbed into the grease and hopefully give it a new bit of life.
Both WD40 and ACF-50 are OK to use with electrics so you don't need to worry about the fluid interrupting any electrical contact - in fact, by helping to mobilise dirt they both improve swept electrical contacts like brushes and commutators.
Hi thank you for the info My old starter motor stopped all together and after taking it apart found the brushes very worn out and the brushes not contacting the commutator but after stripping it down aNd freeing them up it worked but brushes very worn out This one on the car now seems free but struggles to turn the engine
Sorry, you said "connections fine", but are you saying now the brushes are worn out also on the present motor? If that's the case, then is there a problem with simply fitting a new set of brushes ? Certainly poor contact at the brushes, and loss of electrical contact area, will reduce the amount of current reaching the windings of the motor, and hence reduce the torque.
The Brushes on the original motor worn out and it stopped working so I could maybe replace them and refit that one that’s the reason I changed it But the one that’s on it now runs slow I’m thinking it maybe easier to just replace with new or recon unit
mybug: Anyone know the whereabouts of PTO 365M? It was mine back in the early 80s and some pix have surfaced here (apparently from ebay around 5 years ago) so is it still around?

karl: Andrea, just seen your post. if you're still looking try putting it in the for sale wants thread.

mybug: Searched and spooled through every image/video/old ad I can find on the internet, I'm thinking that PTO 365M is not around any more. May be resting in a shed, but given the small and tight-knit Bug community, I'd have thought that someone would know it.

crabo: Does anyone have the registration plate numbers or the chassis numbers for the Rothmans Bugs (six of). I friend of mine has just purchased a white Bug (700E) in need of restoration, reg URC 42L, chassis no BR62313, eng no 9816.

jefferdp: All, does anyone know the size of the headlights on the bug, Some say there 7/6" but that seems a little large to me. Also where can you get replacments now?

fmb4: My Bug has nothing but a hole where the canopy latch should be. Any help in finding one would be greatly appreciated!

heartnut: Quick question: If I fit a Lucas 15/16/18 alternator, is it true that it will heed fibreglass work to fit it as the body is bigger than the original generator?

rolydog2001: I have fitted a Dynamator to get around this, looks original and gives the same output.

fmb4: I am in desperate need of a latching assembly for my canopy. I am restoring, and have only a hole where it would have been. Any help would be greatly appreciated. Maybe some one could send me detailed photos of same so I could perhaps have one made
