I'm restoring a 1960's Scott Bonnar Supercut which has the original Villiers 12/2 still attached to it via a dual (original) belt drive. The drive pulley on the engine is not much longer for this world and I was just wondering if anyone knows where I need to go to try and find a replacement type pulley. I'm really not sure what kind of business would have this. I'm in Perth.
I don't think there is any realistic prospect of finding a New Old Stock pulley anywhere. The chances of finding a scrap Supercut with a good pulley are not quite zero but pretty close to it, and you have taken the right step by posting your need for it here, though the "Wanted" forum might have been a better place.
If all else fails you can either repair your old pulley, or have one made. It should be a routine lathe process except for the grubscrew tapped hole and the internal keyway, assuming it has those features. However before resorting to having one made, you should see whether a supplier of industrial V belt pulleys happens to have one to suit. This could easily be the case if SB chose to use a standard industrial product on the mower, rather than re-invent the wheel by designing a special one. Here is an example of the type of supplier I have in mind: http://au.rs-online.com/web/c/pneum...82a&gclid=CPrF_qqYgcYCFdd5vQodRgQA6w
I do not know or recommend that supplier, they are merely an example of the type of seller you are looking for. Note there are also some thousands of different V belt pulley types on offer on ebay.
Hey Grumpy, thanks for the uplifting reply......heheheh
I still have the original, however it's stuck like superglue to the crankshaft of the reduction box. I will get it off but it will take a lot of time/effort. I was just seeing if there was an easy option of grinding the stubborn bastard off and renewing it?
Prospects of getting the pulley off by destroying it without damaging the output shaft are not good. What I suggest you do, is soak the junction between the pulley and the output shaft in penetrating liquid (such as Penetrene or similar specialised penetrant, but not WD40 or similar, which does a poor job as a penetrant) for a day or so, then be sure you've removed the grubscrew, and use a correctly-sized gear puller to pull the pulley off. Correctly done, this will not damage anything and except for waiting for the penetrant to take effect, requires very little time or effort. If it turns out your shaft is particularly rusty and particularly tight, you may end up having to heat the pulley, but this is semi-desperate stuff, since it will destroy the output shaft's oil seal.
Thanks for the reply Grumpy. I have said pulley soaking in Penetrene as I type. Grub screw removed, and correct sized pulley-remover on stand-by....will leave it to the weekend I think. I really don't want to screw these parts up as I've waited a long time to get hold of a Villiers 12/2 with a standard reduction box which I need to get the Supercut going properly.
You are welcome Mark, and I completely agree that this is a job that needs planning and thought rather than deadlines. When it comes to restorations, repaired isn't nearly as good as not damaged in the first place.
Could you please post some photos up of your machine as the Supercut is starting to attract more attention on the forum and every bit of help really does count for the members of this fabulous information medium.
Cheers, BB
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
Here's a pic of the Supercut. Please ignore the colour scheme, the black engine is one I've had for a while which has just been waiting for a purpose. All bits will be suitably red and green when the resto is done.
