I don't know why you'd worry about replacing it as the exact part unless its a collector. From what I'm seeing it seems like its unlikely. Freewheels are a consumable part that are going to need replacing over time, only the most anal collectors care about them matching exactly.

For an easy swap, just replace it with a 6spd freewheel. Any shop that thinks that part is hard to find wouldn't have my business for long. It's a direct swap with maybe a little adjustment of the limit screws. The old 600 Arabesque derailleur should handle 28t fine.

One piece cranks are pretty easy to work on so they are a good intro to working on bikes. The only tool you need is a big adjustable wrench and some grease to get them up and running.

Six speed is the correct terminology. Bike speeds are typically expressed in one of two ways, the amount of rear cogs multipled by the number of front chain rings (7 in the rear 3) or by the amount of rear cogs.

If you decide to replace the chain, freewheel (rear cog set) and chain ring you will need the following, chain, freewheel, and example chain ring The chain ring you get needs to say that it works with chains that are 1/2 x 3/32. If you want to be anal about this, you can count how many teeth are on the small cog and big cog of your old freewheel and get a new one that matchs that range along with getting a chain wheel that has the same amount of teeth as your old one. This is likely to preserve your old gearing. This is not a huge deal for casual use, though it's something to keep in mind.

You will need a freewheel remover tool to get your old freewheel off. There are about ten different ones, so I would suggest going to bike shop and having them remove it, or have them tell you which tool you need. You don't need a tool to install a new freewheel.

Also, to install the new chain you will need a chain breaker.

However, I still doubt you need to replace all that crap. I'd start by fixing the bottom bracket, then seeing if that solves the crunching and chain jumping problem.

This Shimano 6sp freewheel cluster is a good option for your driveline in terms of durability and shift quality. No real need to go to 7sp as the incremental difference isn't worth the added strain on the rear axle (7sp freewheels place extra loads on the rear hub/axle assemby).

First off: watch out with "26 inch" wheels. There are no fewer than 5 different, incompatible "26 inch" sizes which you are likely to encounter!.

Since 26 x 1-3/8 wheels are not used on modern bikes, your options are going to be a bit limited. You definitely want an aluminum alloy wheel (instead of steel). Here is one in the right size and material, that accepts a thread-on freewheel. It is a bolt-on wheel, however (not quick-release compatible). The seller does not indicate what the axle length is, but I think only one axle length was common for 26x1-3/8 wheels. Good luck!

Really hard to help you on the gearing situation without pictures. What kind of shifters does it have? Is the rear shifter indexed?

You may be able to just buy a new 6-speed thread-on freewheel, if the shifter is not indexed (or is indexed for 6 speeds). They are not expensive, and can be installed without a tool. You'll need to replace the chain too, btw (the chain and rear gears wear together). I would prefer this option, if at all possible.

If you simply must keep the old freewheel with bizarro gears, you'll have to figure out which of the various freewheel removal tools it takes. You'll also need something to apply serious leverage to the tool, as freewheels are tightened by the force of pedaling. A bench vise is best. Plenty of youtube videos demonstrating the removal technique.

As everyone already said, you need a new freewheel.

I cant tell if thats a 6 or 7 speed freewheel, but here is the 6 speed and
here is the 7 speed part you want.

and you need this to get it off.

There are a million freewheel replacement videos on youtube that you can watch to see how its done. Once you get the old one off ( and it will be a bitch to get off... most freewheels are) popping on the new one is stupid easy.

I'm no expert, but a lot of that price will depend on what kind of cog set and chain you're getting!

You need to make sure it's the right kind/size of chain for the job (OCB can help with that too as they offer them for sale), but chains for not-super-fancy-racing-bikes range from $12-$50 retail (usually around the lower end of that range, say $15-25 being fairly typical).
What set of cogs you get will depend as well on what quality and range of gears you want and what's compatible. For my old bike's freewheel (freewheels are cogs that come as one complete piece vs modern cogs stacked on a cassette - freewheels are generally only seen on old 70's and 80's era bikes), I paid a little under $20 but if you're getting a high end cassette, you can easily spend $100. More basic ones run say $25-$60 on average (ala https://www.mec.ca/en/products/cycling/bike-components/drive-train/cassettes-and-freewheels/c/828).
Shop time at OCB is $20/hr. If it's your first time doing it and you need a lot of help, you're probably looking at an hour (if experienced should be more like 15-20 mins, though maybe longer if you're changing things vs straight replacing things and need to tweak your shifting to match). So $20 plus let's say you snag a $15 chain plus $30 cassette (cogs) after tax then you're looking around $65-ish at OCB? So say $45-70 depending on what you want/need/how long it takes you but something in that ballpark for non-fancy things. So $80 to get a shop to do it sounds fair if they're including parts.

OK this is slightly confused. How many cogs are on your freewheel cluster?
I'm guessing 5, making your bike a 10 speed using the two chainrings at the front (2x5). This freewheel would usually be replaced with a similar cluster (5 cog) although you could go 6 without too many issues, like this Shimano unit although best to check if your rear derailleur can handle 28t.

u/lavacahacemu · 1 pointr/bikewrench

largest I could find on ebay NOS. By no means affordable.

If the shifting is friction (i. e. doesn't click for each cog), you can replace the rear wheel with anything 6 or 7 speeds, check out craigslist and you can probably get a decent old wheel with freewheel for about 20~30 usd.

Upon further reading it seems that freewheels have a standard ISO threading, therefore, again, if you're ok with friction shifting, you can use any old freewheel, even a new one. Not completely sure about the spacing and/or overall width though, so, give it a try.

Here's a wheel. It has a quick release axle, but will work well.

You could either buy this tool to remove the freewheel (gears) and switch them to the new wheel or you could buy a new freewheel set.
