Intro: Change the Oil in a Vintage Honda CB100
I've had this bike for a while and have decided it's time for an oil change as I've not done that yet on this bike. so here we go.
first, it helps to have a service manual... for capacities and torque specs
Step 1: Drain the Oil
Step 2: Remove Kick Stand
to remove the clutch cover to access the centrifugal oil filter you'll need to remove the clutch side crankcase cover. This requires the removal of the kick starter, the foot pegs and the exhaust system.
Step 3: Remove Exhaust
Step 4: Remove Kick Starter
Step 5: Loosen Screws on Clutch Cover
Make sure you use the correct screwdriver there are many types of "phillips" screws. they are NOT the same. These screws are easy to strip the phillips head. after some rummaging I was able to find the correct screwdriver and removed all the screws
Step 6: Whack It!
breaking loose the cover is easy with a couple taps of a rubber mallet
Step 7: Save the Gasket!
I didn't have a replacement gasket on hand so I tried to save as much of the gasket as possible and will be sealing it with gasket maker upon reassembly.
Step 8: Clean It!
clean out any sludge you see as well as anything you might find in the centrifugal filter
Step 9: Back Together!
I'm pretty sure that this is from my grandpas time and probably highly toxic but it works wonders!
Step 10: Remove Filter Screen Cover
Step 11: This Is What Comes Out...
clean the screen well and check for any metal filings.
Step 12: Shine It Up!
before putting the bike back together I decided to do some polishing... it's easier with the parts off... and why not?
Step 13: Test Ride!
After putting the bike back together and filling the fluids of course!
after a short ride make sure everything is torqued correctly and there are no leaks! and you're done.
