Road Wheels with Plain Bearings

[ajmac]

I found two different brands of ball race, one with a steel cage and one with a Brass cage both I would presume are wartime. Although I consider the plain bearings historically significant they are all too badly worn to use in anger. Well they could be used but the wheel would rock a little so I will replace all with ball races. I have cleaned up one plain bearing to keep out of interest and the rest will go for scrap during the week. Does anyone have any spare spacers and seal assemblies? I am hoping the Loyd range wrecks will yield some small spare items for the bogie builds.

I can see the plain bearings working well in slow-speed load carring applications.
These days Carrier restorers sometimes have to compete for wheels with people restoring static machinery etc.
Maybe they would be glad to fit those plain bearings Carrier guys are tossing out?

Hanno:

In all cases, we have taken wheels with scrap tyres and left good ones in the system, we have never used wheels with good tyres that could be re-used by a Carrier owner.

In any event, 1940's rubber is a bit past its sell by date and anyone contemplating using such needs a word of caution.

The bearing sizes are Imperial, not metric, so the ID is 1-1/4" for a genuine bearing, the 50mm ID is what we used on our engine trollies. They are about £6.80 each if you buy 10 off ebay, size is 6310 by memory.

Buying unbranded bearings is a bit of a leap into the unknown, but bearing sources are so widespread now that you are probably going to be pushed to find a bad bearing.

We have two engines on the wheels now, the first set were re-used on our second trolley, but we plan to ship those over to Roy next year before the Nuenen show, so that we can collect a re-tyred set from him.





Regarding using plain bearings on the trollies, we find that the extra drag makes the trollies hard to move, they go over a ton each. Roy's new tyres have been good, no problems at all and the rolling resistance is low compared with rubber.

Lastly, a picture of our trailer/RV that we carry our largest engine round in and where we live and sleep while at shows:



This was taken this Monday as we were about to leave Little Casterton in Lincolnshire.

Regards to all,

Road wheel and return roller bearings are listed in the 1944 Loyd carrier manual I have and are listed at metric parts rather than imperial, just to be clear.

Yes Peter, As Al said, the original bogie wheel bearings are metric. 14 of them are 110 x 40 x 29 ( 6408?) and the front inners are 110 x 50 x 29 (6310) (from memory?)

BTW, your gen set looks great! and I wouldn't have any problems with you using good wheels.

indeed it does, it was manufactured at the factory in which we still build gen sets today, a little larger though, upto 15MW and powered by Gas Turbines.

Both engines are Ruston & Hornsby Lincoln, but the driven ends are both Mawdsley, Dursley, Gloucs.

The vertical diesel is a 1YB dynamometer set, supplied new in 1959 to Huddersfield Education Committee, the horizontal is a Ruston 1ZHR with a Lister Start-O-Matic alternator/starter, this was made by Mawdsleys as well. The engine came out of Abingdon Technical College.

Yes, not sure why I went off on that tack now, as the 6310 is a Metric bearing....

Apologies!
