HO Bach 2-6-0. Can I turn drivers in place on axle to try to quarter it better ? Loco lifts up and down very very slightly per each wheel rev..Visually it does look as if one side, rear driver when side rod is at 6 oclock, other side is say, 9:05-ish.. I don't want to purchase that quartering tool if I can do it by fingers and eye..It's of course, very tight and am afraid to force it ...Any dibbs ?
If you have to ask, don't try it by hand. Seriously.....I would it, had to before, takes a couple of tries, but if you never have, you need to get the tools. That said, it's all the drivers on one side need to line up, then go to the other side...do they line up with each other? Usually a bump is a valve gear or piston issue. Take all the main rods and eccentrics loose and see what it does (tie them up lightly over the boiler with a small piece of wire). Dave
Thanks Dave..But I'm not sure how to get pins out of wheels... They are not slotted for a screw driver. Do they pull straight out ? If so, is a hemostat good for this ? I know eccentric is a hex nut. Also, being you sound very knowlegable, could you tell me how to get boiler off to possibly lube motor bearings on this and on a Bach ten wheeler (HO)...Not positive which screws they are except big one under smoke box (typical)...Someone once sent me pics of this but they where sort of nebulous...
I remember several years ago, I talked to the Bach-Boy on the phone about one of their H0 steamers someone was having trouble getting apart. He told me that particular loco was not made to come apart. I told him to send me one, and I would publish the "procedure"...he never did. Don't have one, never worked on one.....I have some Bachmann in LS, most with new aftermarket drives or drive components, nothing in 0, H0, or n. If the crankpins won't come out.....boy, that's a toughie. In LS some had pins that pushed in, but getting them out in H0.... Do you have a parts breakdown that came with it? And no hex on the crankpins other than the main driver?
Sheesh guys, so sorry if I'm a closet repeater..So many issues and tissues these days I'd forget my head if it weren't screwed on !! Yeah, the 4-6-0 is/was a similar problem (in NYC I knew a Greenwich Village beatnick in the early 60s named Iswas). On both it's very minimal where I've rid them of much of the clumsiness via the CVs which control the motor. The mogul does this kind of jittery motion until past about 5 mph. But, as I said she slightly lifts or rocks up and down, causing me to believe side rod is binding. Good point about parts breakdown..This will show pins but still nervous about pulling them and turning wheel on the axle..Could become a can of worms I'll regret...but thanks..
I have personally given up on Bachmann stuff. Several years ago. Many (many) many reasons. We do not know if they pressed the drivers onto knurled axles. If they have plastic centers, maybe. By guess or by golly twisting away at drivers will get you scenery in the weeds behind the roundhouse real fast. You need to run it slow, off the rails, and watch. I mean, I've seen piston rods too long (or cylinders not cored deep enough), crosshead guides bent a tad allowing the crosshead to impact the #1 crankpin. Siderods bent slightly. Main rod hitting the rear crosshead guide support. Valve gear parts not riveted tight enough, flopping around and catching other parts. So, when you run it, watch for the parts hitting something. Watch for a bind. You could even have a split gear on the axle doing this (and boy, is that company known for....). When it binds, see exactly what the angle of rotation of the driver is you are spotting. Then creep up on it, stopping exactly at that spot. See what component is loose, and which is tight. Do all the rods "rattle" slightly? Or is one hard enough to play a tune on? Is it a siderod tight? Main rod? Eccentric rod? Gotta know before we go twisting. Dave
Yeah, 10-4 on it all..On this subject, what is the best sound equiped HO steam manufacturer now ? B'way Limited ? Maybe treat myself to one one day..Odd, the Bach ten wheeler gives me more hassles than the cheaper non Spectum mogul...and the mogul has the brightest leadlight I've ever seen where the ten is the dimmest/worst and no backup light ! I can't get why makers have so many variations of features/functions in items which are all say, steam locos, all HO, all stamped out at same factory, same plastics, same detail addition(ing), same employees, same designers, etc etc...Why can't they universalize common parts like lights, rods....already already...
