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
tmallen: Just registered as I am looking to purchase a BB, I have one in particular that I am awaiting more information on. In the meantime, anyone got one for sale or know anyone who has, please send me details. Thanks

ayrbugger: Kev, Open up forum and go to bond bug problems...there is a section re removal of body. You'll need three strong blokes or as I did a hoist and a support frame, and a strong beam in your garage to hang it all off.

V8 Bug: I owned bought a bug in 1972 and had 3 years of fun with it. Around that time I saw an article about a number of bugs that had been fitted with V8 engines for an Arab prince. I think this was done in Wales. Anyone know anything about these?

Stiffy: Your better of posting a question on the forum. One earth goes to the chassis from the battery negative. Then anther goes fro the wiring loom onto a bolt ontop of the gearbox cover. :-)
