2-10-2 sticky wheels?

[Phil]

hello my freind has just purchased a 2-10-2 today ad we ran it on the track and it ran very jerky we've cleaned the wheels and skates and lubricated the valve gear but still sticky
anybody hd this problem?
thanks phil

Do you mean it moves in a series of very small jerks.?

 

[stockers]

or it runs but hesitates now and then

 

[Phil]

it runs but when it does the wheels slow down on the top right hand corner of the rovoloution in the wheels
and its not timing in with the syncronized smoke and sound well not really it chuffs then about 2-3 secs later its chucks abit of smoke out

 

[stockers]

I have to say, the synchronised sound is not very synchronised - also the smoke chuffs. Looks good but not quite in time.
Two posibilities I thought of.
1. Many sets of valve gear 'appear' to slow at one point of the revolution - I think this may be an optical delusion caused by the linkage.
2. Having said that, it may be that you have something binding inside. Drop of the base plates but dont release the wheels from the cogs - check lubricant (not swimming but a bit showing) and check the gears for damage.

This is worrying!

It sounds very much like there may be a gear set out of synch , remember this loco is effectively a 2-6-4-2!
as it has a 6 wheel & 4 wheel 'powered set up to allow it to get round tight radius curves,

Check to see if the wheels on each whhel set are correctly 'lined up with each other, best done by observing the position of the connecting rod pivot on each wheel, if anything is found amiss then it should be possible to corect by removing the keeper plate from the underside of the relevent set of wheels and adjusting the position of the wheelset by lifting it out of gear and rotating it until correctly positioned,

This could account for the problem with the sound.

one thing to add though this is a recently acquired loco It is obviously not correct so I should involve the seller before doing anyhting drastic,

I dont currently have a 2-10-2T but when I did I never had any running problems

 

[stockers]

Good point Steve - you could well have hit the nail on the head.

 

[stevelewis]

What also has to be considered is why the fault has occured in the first place....................... as we know LGB is very resiliant usually, but it could have been dropped or something similar so it is worth considering if it needs to be rejected as unsuitable for use ( or get a big discount!)

 

[stockers]

Is it brand new?

 

[Phil]

no its second hand from a guy who died in cyprus
ian s is selling all his stuff off for the guys wife so if you want to contact him feel free.

 

[stockers]

I am pretty sure Ian can help if needed - or he knows a man who can!

Sounds like a wheel quartering/jumped a cog issue Alyn

Hey Phil,

Is it the new one or the old original model. My mate had an old one and he had no end of problems with it. The front and rear motor drives get out of sync and do that. He took it back to the local yokel and they were unable to stop it repeating the problem. In the end he modified it himself and has not had a prob since. Will contact him to see what he did. It wasn't much. Before that he took off the bottom plate and requartered the two drives.

hello mike is going to have a look at is soon i think so thanks for all you help!

agreed

and as i recall on this mechanism,

there is a universal joint connecting the two sets of drivers-this might have slipped or been damaged-or not


start with the quartering -binding is often this -and even one tooth adjustment can make it all better

not likely to find another sound and smoke synched 2-10-2, i dare say

 

[Phil]

SORTED!

 

[mike]

yip, re set quarting oin both blocks

 

[Phil]

thanks running sweet @ nwag meeting
