Good news first: Thank goodness these exist!!!!! I lost mine to the Earth during my oil pump rebuild. Mixed news: As-is out of the bag, this reproduction pin was slightly too long. These pins require just a smidge of filing to be the same length as the factory pin to allow for the pump drive gear to freewheel via both pins becoming flush with the shaft. I estimate around .010 inches (or less) got filed off but it probably varies by application. I had an existing one to compare it with while filing. I understand these parts are probably tough to make in small quantities and probably have a wide tolerance range. Not a big deal! Overall it's a great product! Thank you HVC Cycle!
This is the only place in the world! where you can find these rare items.. Excellent fast postage!! (Of which! is faster than the uk's 2nd class postage!) but has usual! the excessive import/postage charges for something so small! Iets us down!! absolutely scandalous!!! I think it would have been cheaper moving a horse from one side of the village to the other!! I understand that it's not the fault! of our friends across the the pond!!,but it's the modern bureaucracy of which we live! Still a great quality product of which!,can only be found at HVC.. Please keep the "two stroke fires"burning!!!
See if you can find the springs with the pins. Thanks!
These pins are a life saver! They mean not having to buy another autolube pump to rob parts off of. a great product and you can't beat the price!
