Want to learn by doing the Maintainance & mechanical tasks on:my 1967 Schwinn Varsity & 1974 Schwinn Super Sport.
So far tools came from my Auto tools; including Penitrating fluid, (I avoid Fire-wrenches) .
Want tools for crank - axles; especially cassette gears, ( including a Torque wrench ?)
Have Not seen a Kit specifically for the 10 spd Schwinn.,and hope to have something portable.
Would I get lost finding a Service Manual ? Maybe a Digital Copy??
Links/ suggestions appreciated >Slohan47.

Most things on those two bikes can be taken apart with a set of box wrenches, or maybe a crescent wrench since they likely have a mix of metric and SAE sizes.

If you've never done it before the cranks look like they need a special tool to take them apart, but they usually don't. Look online for how the lock ring comes off and then it's pretty obvious from there.

If you want to remove the gears from the rear wheel you will need to find the correct freewheel tool. I suggest going to a local co-op or bike shop since this tool is not usable for anything else, you might need two different ones, and if you try to order it from the internet there is a significant chance you will order the wrong tool on your first try. Many local bike shops will break the freewheel loose for free because it only takes a minute if you know what you're doing (and it isn't too rusted in place).

If you want to true the wheels or replace spokes you need a spoke wrench. You can get one that handles multiple sizes pretty cheap. But if you're doing more than simple adjustments you probably need a truing stand. Again, local bike shop or co-op is your best bet.

Welcome to the forum. Tools abound. A good start for a 70s bicycle along with your regular car tools are...

Cheap Cone Wrenches
Park MT-1 Wrench
Spoke Wrench
Chain Breaker
Chain Whip & Appropriate Freewheel Socket
PB-Blaster, Marine Grease, in addition to what ever Car Oil and ATF you are using


With the internet and youtube ya really don't need any books. Look up Sheldon Brown, and on youtube RJ the bike guy. Ya already found this forum. And by the way after 10 posts we do like pics when addressing a problem.

Oh... And dont forget to ask about a more comfortable seat and high tech expensive lubes that clean your chain automatically... Ha

Your bikes have freewheels, not cassettes. Torque wrench would not be applicable, because freewheels thread on to threads on the hub, and tighten down the first time you pedal the bike. No need for a chain whip uniess you intend to remove the cogs from the freewheel body as part of the service, which the freewheel may not need at all.

I'm pretty sure your Varsity, and possibly the Super Sport, have one-piece cranks. Serviceable, but quite different from more modern common 3-piece cotterless cranks. RJ on Youtube, as mentioned above, covers the process.

I'd start off with some basic repairs/upgrades and learn how to do those first. Replace the brake shoes. Make sure the chain functions properly--smoothly, with no kinks. Learn how to measure the chain while you're at it. Change out the brake and derailleur cables--both housing and inner cables. Clean up and polish the bike so you can see what you're doing. Remove any rust everywhere you can. Change the inner tubes and maybe even the tires.

I'd get all these basics down before moving on to wheel axles, headsets and bottom brackets.

You will find out that working on most C&V bikes, at least from the late 70's and up, will require allen head wrenches (metric). It is something that a "car oriented" tool set usually do not have.
You can usually manage without a lot of proprietary bike tools for a while if you are just doing very simple maintenence and repairs, but eventually, you should gradually accumulate the special bike tools as you work on more bikes, as it will make the work much easier and you will get better results. Going through tool catalogues like the ones from Park Tools will help you discover what these special tools are and what they are for.

Searched for Glen's Repair Book; found at ABE's Used- $4 for 1st Edition. AlsoService Manual: Insurance that most likely the Job will be done "RIGHT" meaning robably not be on side of the road wondering WHY?

I did my first bottom bracket overhaul live on this forum. And I found it to be just like adjusting old school automobile wheel bearings. Practice, practice.

Tons of good advice.
Its always nice to see a picture and some tools eye candy like the campy tools that came with the top of the line Paramount bike from SCHWINN. This makes for a nice show with my paramount but not what I use for rides as I have a bag with common tools for all my rides. Many threads on tool bags riders carry, search BF

Velox tire patch kit
15mm Wrench - Brev Camp Italy - 769 "Peanut Butter" named
Classic 5mm "Pineapple" Allen wrench from Campagnolo
Vintage Campagnolo Crank Puller Extractor Tool VGC
Vintage Campagnolo T Handle Tool 8mm Allen Hex Key
4mm / 5mm not marked
The 7mm is marked Cinelli.
The 5mm is Campagnolo.

I’m a car guy and agree with 👆.

Since we’re talking about 50+ y/o bikes I would add some sort of container, brushes and degreaser for cleaning stuff with caked on dirt and grease. I don’t know how many small brass wire brushes I’ve used up.

A cheap digital caliper for measuring stuff gets used very often by me.

The original idea of Schwinn bike engineering was to keep it simple. Any task could be accomplished with a 1/2" wrench, flathead screwdrive, and large adjustable wrench for crank and headset locknuts. The one piece Ashtabula cranks are the simplist of crank BB design and require no specialty tools.

I think the only metric nuts on a Varsity will be for the Weinmann brakes, 8,9,10mm. Seatclamp and stem/handlebar adjustment will be 1/2". Pedals are 1/2". Super Sport will be the same except for the stem bolts which are 12mm.

Both your bikes will have 5 speed freewheels that most likely are Atom/Millard and require a splined design freewheel remover... Combined with adjustabke wrench or pipe wrench will unscrew counterclockwise.
