o.k., i have a 1972 CB175 engine that i'm trying to make smaller in anticipation of my upcoming move.....

first of all, i don't have a manual, and i really can't afford one ($ or time), so any help is appreciated!

how do you remove the oil filter after the center philips screw is out?

what will help me turn the cam chain so i can remove it from the sprocket, to remove all things top end?

any trick to getting the clutch basket out? i have removed the clutch plates, springs, and such already.

tex

p.s.- i am amazed on how good the motor looks so far. oil was oily (and not a watery, white gooey mess). most bolts/screws came out easily. i did however, go through two philips inpact bits, and only hit my hand twice with the hammer. being sober helps!

Tex,
Oil filter removal- An 8mm X 1.25 screw will thread into and remove the cover by pressing against the end of the crank. The castle type nut inside the filter housing will require a special tool be bought or fabricated from that old Taiwan socket rolling around in your tool box. Here's a link to one at Dennis Kirk. The same tool is used for the CB750 clutch nut.

Timing chain- Use the kick starter to roll the engine over until you find the timing chain master link. If the engine is siezed you will either need a link pin tool to remove a standard link or a cutoff wheel to cut the chain. New chains are cheap and all over E-bay.

Clutch basket- Because of the offset teeth on the clutch basket and crank gears, you will need to remove at least the outer crankshaft gear to free the basket.

What Bret said (with such efficiency too).

P.S. Under the castle nut there's one of those star washer type dealies with the tabs bent up. Also, the castle nut oil filter setup is common to probably all early Honda twins, so once you have the Dennis Kirk socket and you decide to fully come over to the Red side, you're good to go.



Honda go sideways!

Don't forget the snap ring on the input shaft at the center of the clutch basket...and...you have to remove the oil pump to get the clutch basket off. The oil pump plunger is attached to the back of the clutch basket so the two oil pump mounting bolts have to be removed and you slide the clutch basket and oil pump off at the same time.

To loosen the nut with the special socket on the oil pump you'll want to jam a penny or piece of aluminum in the primary gears to lock it up.

After you get the top end off you can remove the studs by using a couple of 8mm nuts jammed together at the top threads...I usually use the nuts AND get a nice grip on the stud with vise grips (using the end of the jaws...not the big teeth) and then turn them both together. Some studs will come right out, others not so much.

PS. You can rotate the crank via the castle nut inside the oil filter or use the alternator bolt on the other side.

thanks for the help guys.....

i had to cut the chain as the pistons were seized in the iron liners (rings broken/corroded). removed the head, cylinder, and such.

i'm gonna post a pic of the oil filter. i have a honda oil filter removal tool, however this filter is unlike the cb350 filter that i am familiar with, and i see no place to accept the four prong tool (which i made out of a craftsman 25/64 socket - who the hell is ever gonna need a 25/64 socket?!?!?!?!).

pics later this afternoon. thanks again!

tex

p.s. - anyone got a spare cb350 exhaust insert collar half moon spacer thingies they can spare?

Text...the nut is inside the filter...probably covered in sludge.

Bend down the little lock washer tabs first if you can see them.

huh, go figure.

i got the oil filter off. i don't remember a cover being on the cb350. once i realized that it was there, a little heat and easy peasy.

no, next question. how the f do you remove the cam from the head? there is no room to get that thing out.

i promise this is my last question.
