I found an almost functional Phil Wood Mk.II BB Cartrige in a 20$ eBay Team FUJI frame.

Contacted Phil Wood, they said they would take it apart, derust it, and relubricate it for 37$.

My problem is that its current spindle would be too short for my frame. I upgraded my Raleigh Olympian to a Sugino MP 110 crank and the BB that came with the crank from a 1988 Giant RS930. I just measured that spindle and it's pretty much 140mm.

The PhilWood BB spindle is exactly 113mm long. My plan was to ask them to trade up for a longer spindle while they were taking apart my BB at their site. My intuition tells me they have a crate of dissasembled Mk.II parts lying around at their HQ that would work without a problem.

Im also new to the JIS vs ISO thing, so im trying to figure out if theyre both the same or which is which. Phil Wood makes both, so they might still be able to clomp something together for me perhaps.

Both are Square taper. The Phil Wood one has threaded holes on the ends though.

The ends on the Phil Wood look wider than on the one from the Giant, making me think that its a JIS and my current one is an ISO.

I have used Phil BB's and to tell you the truth I would recommend a shimano sq. taper bb. Are you sure about the axle length. 140 seems awfully long.

Yeah, it sounds like you are measuring the threaded ends of you spindle. Just measure to the end of the square taper. Sheldon Brown has an article about ISO vs JIS tapers - I can't remember which is bigger off the top of my head.

I would just get new cartridge bearings and clean the spindle and cups you have if it is reasonably close enough in length to what you need.

What? Isn't 113mm a normal length?

The OP states that the Fuji's original BB spindle is 140mm long... which leads the others (and me) to believe that he measured the entire length of a nutted-type spindle. A more typical length for that crank would be 122 or 124mm:


He should be measuring to the ends of the square taper (dimension D):

operator

Right.

The Phil Wood one from the FUJI is 113mm

The Sugino? one from the Giant is 140mm total.

Will have to take off crank and other arm to measure the correct taper-to-taper length. Ill also take some photos with my phone.

JIS is slightly larger across the flats at the beginning of the tapers.

Also replacing a spindle is an upcharge at Phil so you need to ask before you have them do it. (Along with get the correct measurements).
If you need a JIS spindle you might be better off just getting a new shimano cartridge BB and putting this one back up.

unless you have access to arbor press or some other type heavy tools I don't believe the Phil is user serviceable.

for a $100 BB having it overauled for $37 counds good. do you have the Phil tools?

as far as Phill BB, they are nice however I found installing and torquing them was a bit awkward. the BB does not tighten against the frame but against the cups. you really need 2 Phil BB tools to do it right

The results are in: shell width 68mm, spindle length 113mm-116mm.

I could not get an accurate measurement without calipers or taking it out. I hit 115mm the most times, doing it by signt and with a multi-hex wrench tool as a caliper.

how do I measure shell width of the Phil Wood BB, cup end to cup end or ball bearing ring end to ball bearing rind end?

I have the one that I used to remove it. Using 2 may be a good idea because ive never installed one of these before.

Can anyone tell from the pictures which one is ISO and which one is JIS?

I would take the spindle out of your current BB and test fit the crank onto both spindles to see how it works. There are several things that have to happen to use the Phil BB.

1) The spindle can't extend past the end of the crank holes or you won't be able to tighten the crank to the spindle. If you use a JIS spindle this won't happen unless the crank is ruined. If you have an ISO spindle and a JIS crank, the spindle might (but probably won't) be too small and it will extend too far through the holes.

2) The crank arms will hit the BB shell. If you get past #1 above, this probably won't be a problem but it is good to check before sending out the $.

3) The crank arms will hit the chain stays or be too far away to give you a decent chainline. Either test fit the Phil BB into the frame and attach the cranks or just eyeball the distance between the BB center line and the crank when the cranks are installed but not in the frame. Doing this measurement carefully should give you the exact size of spindle you need from Phil as long as you match the taper you currently have. If you switch tapers, you will have to adjust the spindle length as the crank will sit either farther in or out on the spindle.

OK so I went to Phil Wood in San Jose in person, and they refurbished my MK.II BB for 37$ !

I also told them by bike specs for the 83 Raleigh Olympian (with my components), so they seemed to take that into consideration when putting the BB back together. They also said they would do any modifications or spindle replacements for free by mail, if the stuff I got was wrong.

Now I need to get crank bolts, figure out threading on my frame and BB cups then put it all together.

Going back over the installation, how easy is it to install a Phil Wood BB? I have one tool, locking compound two rings, and a bottom bracket cartridge. I can try to do it at home, take it to a co-op (Bikerowave) for 7$ an hour (where they may have a second PW tool), or to a bicycle shop up the street for probably 20$ charge.

If the PW BB was in a 82 Team Fuji, is the threading on the cups Japanese? Is the threading on the 83 Raleigh Olympian made in Taiwan Japanese? Is the threading on cups that came with BB out of 88 Giant RS930 that fit into my Raleigh Olympian Japanese?

I wonder if I could get this one refurbished for $37?

Email them, at the email listed on their website. If it is a PW then probably yes.
