1989 Trek 330

                                                                 1989 TREK 330    

                                                                           

                                                           Trek 330 (when I found it)              

I scored this Trek 330 in a package deal with a couple of other bicycles. It's missing the front wheel and saddle but I think I can make this into a really nice bike. This bike also sat in my shop until I could find the matching front wheel. The front wheel is a Weinmann 415X wheel with a concave rim.  It took me about two years of searching and I finally found the matching wheel on Ebay. After I found the wheel I started to disassemble the bicycle.


These are some pictures before disassembly.

Bottom bracket and cranks.

The frame was very dirty . The top tube , down tube and bottom bracket shell had some black grime all over it. I tried cleaning it with some degreaser but it would not come clean.  Also the frame had some paint spatter on the right side, probably house paint.

I used some Maguire's Ultimate compound to remove the black grime from the frame, the compound also made the dull paint shine again. Then I used Mothers carnuba cleaner wax to remove the house paint overspray from the frame. It took about four hours of rubbing the frame with carnuba wax but I finally removed all the paint over spray.

Next I worked on the head set. The bearings were in good shape but the chrome was badly rusted. I cleaned the headset parts and soaked them in metal rescue. Metal rescue is a rust remover . I soaked the headset pieces for two days then I polished them with Turtle wax chrome cleaner.

Headset and bearings (before)

I then pressed the polished headset cups into the headtube of the bike.

Headset cups pressed in.

Next I greased the headset bearings and installed the fork.

Next I installed the fork and adjusted the headset.

The stem and handle bars were next to clean and polish.

Stem (before)

I wet sanded the stem , using a 400 grit sand paper and moving through to a 2500 grit sand paper. After wet sanding I polished it with Mother's aluminum polish, then buffed to a nice shine.

Next I cleaned the old glue off the handlebars with some degreaser and a SOS pad. All the grime came off nicely and the sos pad polished the handle bar as well. When I was done I polished it with Mother's aluminum polish.

After cleaning and polishing the stem and handlebars I installed them on the bike. Both the stem and the handle bars are basic Trek issued components.

I still need to adjust the height of the stem . I will do that when I test ride the bike.

After completing the front end of the Trek I began to work on the cranks and bottom bracket.

These Sugino VP touring cranks are in great shape. They cleaned up nicely with some Mother's aluminum polish and some bronze wool. I took them apart and soaked the chain rings and bolts in Metal Rescue to remove the light rust, then cleaned and polished the cranks.

Next I worked on the bottom bracket. It is a square tapered axle with retainer bearings. 

Bottom Bracket (before)

I cleaned and polished the bottom bracket components and then regreased the bearings.

After greasing the bearings I installed them in the bottom bracket shell and adjusted the bearings so it turns smooth.

Bottom bracket installed and adjusted.

After adjusting the bottom bracket I installed the Sugino crank. 

The crank spins fast and smooth. This Sugino crank is a double crankset with  52X40 tooth chainrings which is great for this Trek 330 touring bike.

After completing the cranks I started on the brakes. They are Dia-Compe 5000 side pull brakes. 

The brakes cleaned up well and shined up nicely. I used Mother's aluminum polish to to clean and shine the brake calipers.

First I started with the front brake and moved in to the rear brake.

These Dia-Compe brake calipers received new brake shoes

After the brakes were done I started on the Derailleurs and shifters. This Trek 330 has Suntour  front and rear friction shift derailleurs with down tube shifters. Friction shifters do not click into gear like index shifters, friction shifters have to be fine tuned into each cog of the gear you are shifting to. This is sometimes challenging when you are trying to find the right gear but you can fine tune your shifting to reduce chain rub while in gear.

Front derailleur (before)

I cleaned and polished both derailleurs and lubed the pivot points.

The rear derailleur had white lithium grease all over it. I took it apart ,cleaned and polished it . Then I put some lubrication in the jockey wheels and lubed all the pivot points.

Next are the Suntour Accushift levers.

Levers (before)

I used Mothers aluminum polish to clean these levers.

These levers polished up nicely.

Once I cleaned up and lubed the derailleurs I installed them on the  Trek 330.

The front derailleur is installed above the crank. I made sure there was a 3mm gap between the bottom of the derailleur cage and the top of the large crank ring so the chain will shift up and down the chain rings without getting bound up between chain rings.

Rear derailleur (installed)

Suntour shift levers (installed)

The Dia-compe brake levers are silver and black with white hoods. The hoods were very dirty and could not be cleaned without damaging the rubber. I ordered some NOS hoods. The brake levers turned out very nice.

The wheels are the next components to work on. The rear wheel came with the bike. After searching for months I found a matching front wheel. These wheels are Weinmann  415X  700c wheels. I ordered a new tool to remove the rear cassette. I have many rear cassette removal tools but there is always a cassette which takes a different tool.

I removed the tire and the cassette from the wheel . then I trued the wheel.

Next I cleaned the rim and hub with Mother's aluminum cleaner and polish.

I cleaned up the axle and added new bearings and grease.

next I reinstalled the cassette.

The front wheel needed a good cleaning. I also needed to true the wheel. It had a small wobble to it .This hub has sealed bearings that are in good shape .

This Trek 330 is getting new brake and derailleur cables with white housing. First I installed the brake cables so I could adjust the brakes ,then I moved on to the derailleur cables.

I installed the wheels so I could adjust the brakes.

This bike also gets a new chain. After installing the chain I installed the derailleur cables and adjusted the front and rear derailleurs.

New KMC chain.

The seat post was next on my list of components to restore. It was dirty and the binder bolt had some light rust that I needed to remove.

I cleaned the seatpost with degreaser and polished it with Mother's aluminum polish. I soaked the binder bolt in Metal Rescue to remove the rust and then polished it with Turtle wax chrome cleaner.

After completing the seatpost I installed a Trek touring saddle.

I installed white leather bar tape. White bar tape came standard in 1989 and I think it brings in the white decals and blends in well with the white brake housing.

White bar tape installed .

Next I wrapped the Weinmann 415X wheels in Vittoria Rubino Pro 700c tires .

New inner tubes.

Last component to work on is the pedals. I think these pedals originally had cages but I did not have any to reinstall so they are going on the bike the way they are.

I cleaned and polished both pedals then added new bearings and grease.

Pedals (complete)

Pedals installed.

These next pictures are of the finished Trek 330.

This bike was an interesting build . I had no idea Weinman made concave rims. I read that they were supposed to be stronger and lighter than convex rims. I think they look cool and handle well too. The white decals  on red paint scheme looks nice as well. I took this bike for a spin around the neighborhood, the Vittoria Rubino tires are fast. The Suntour drive train shifted nicely for a 29 year old bike. The shifting technology has come a long way since then. This bike was a pleasure to ride the light frame helped this bike get up to speed quick and it took corners well. The Dia-Compe brakes stopped on a dime. This bike was a pleasure to restore and ride.    Thanks for checking out my blog.  Cheers Tony.
