No bronze in mine. Where abouts? Mine is all bearings.Mine did that when I first had it - it was because the two bronze bushes that change the gears were worn out and the gears were kind of bumping along trying to engage both gears at the same time. I re-made the bushes out of a bit of phosphor bronze and it has been fine since (that was 30 odd years ago)!
I have the same drill and mine was noisy too...my gearbox now runs thick 80/90 diff oil and its 95% better

The bearings are all ball race bearings. Mine is a Progress No 2GS (similar to the Meddings, I thought). The gear which lifts up or drops down to select high or low gear is raised or lowered by two little bronze bits fitted into a large clevis and running in a groove in the gear. The bronze selectors and the clevis arrangement is operated by the gearchange lever. Sorry but my engineering nomenclature has forsaken me and, also, it is about 30 years since I had it to bits. The jangling noise caused by both high and low gears trying to engage at the same time was the reason the place I was working at at the time scrapped it, so I took it on.No bronze in mine.

Ah see I'm my Model 4 Mk2 the bronze pieces are white plastic, I should imagine acetal/delrin.The bearings are all ball race bearings. Mine is a Progress No 2GS (similar to the Meddings, I thought).

Not when you paid £50 for it and it does everything its asked.That is likely just hiding the underlying problem, instead of fixing it?
Does the price really make any difference? I don’t think so. It is still likely that the worn bits are still worn and the problem is being hidden from ear-shot.Not when you paid £50 for it and it does everything its asked.
Makes a massive difference, why fix something that is not broke when it breaks in 2087 i will scrap it or sell it to someone who puts less value on time.Does the price really make any difference?
