Hornby Rebuilt Light Pacific

[Philip Hall]

I have heard from David Rogers of Ultrascale who has seen this thread (as a non member). He has done commission repairs for people and the gears produced are not in his general lists, as they were for specific jobs. He suggested you give him a call to see if he has something.

As an example, here is an idler gear set for a Hornby King Arthur, 21t and 25t, which looks very similar. It could well fit other engines. Maybe check you have counted teeth numbers correctly, as 26t might not be correct. The reference numbers on the data sheet might be the same for other engines, since it probably refers to the pair of gears on the shaft.

Thanks for that. I'll contact him next week.

It has 25 teeth

Whilst not being any form of engineer, I do see this as primarily an issue of forcing a shaft into an undersize hole.

That was my conclusion as the force needed to fit the replacement gear was more than I felt necessary. The knurling of the axle is very prominent, perhaps overdone.
Regards
Tony.

I've tested two other rebuilt light pacifics and they both have the same problem. Not a good advert for Hornby.

Hopefully self explanatory pictures of the drive train in the West Country.

The need for the shaft splines was primarily to couple the torque between the two gears,
as they were moulded as separate components. If you are contemplating repair of the split
one, perhaps you could pin the two gears together, and reduce or remove the shaft splines.
You'd only need to retain the shaft's axial position, maybe adhesive would suffice.

I'm opening the locos up to access the least damaged one, to get replacements made.

Quality control Hornby (China) style...

I've opened up one of my unrebuilt West Counties and although the chassis was different, the gear was the same and not cracked. Part L8736 1. Two of the broken ones are L8736. One, the least worse is L8736 1.
Sending off for replacements next.

I think I'd better check my Q1, M7, T9's and J50. Just in case.

[Hardwicke]

Clearly the Chinese factory doesn't care what it turns out. Look at the axle positioning on these supposedly identical Rebuilt Bullied Light Pacifics.

If Hornby have a quality problem shouldn't somebody be telling them.

But the Hornby Rebuilt Light Pacific hasn't been produced since 2010 apart from the Diamond Jubilee one.
As Alexei Sayle said "these are designed to break exactly one week after the guarantee runs out".

They should still sit up and take notice - it doesn't look good for them, especially if it's big on RM web.

The manufactures guarantee is always in addition to your statutory consumer rights. These are that goods should be of 'of satisfactory quality' there is no explicit time scale and they don't disappear just because the timescale of any additional guarantee rights has expired. A manufacturing fault that existed since day one is still covered.

Tbh I don't want another Hornby gear wheel that will fail again in a few years. I had a chat with David from Ultrascale and a plan is in place.

[Hardwicke]

I've checked one of my T9's. The gear is fine but smaller than the WC. The motor mount is another matter all together. It's broken away completely from it's base.

The J50 is up for checking next as is a Stanier 2-6-4T I'd forgotten about.

Discussed this evening in our virtual group meeting. I imagine Phillip Hall would tell you this but he's off on holiday so...
Peter's spares do replacement brackets https://www.petersspares.com/p/peters-spares-ps119-replacement-hornby-t9-rear-motor-bracket-x9945

Apologies if you already knew as it's a common problem.

[Hardwicke]

Thanks,
I got some from Lendons of Cardiff already
Cheers
