Is a Shimano Press Fit bottom bracket the same as a BB30 or similarly named bottom bracket? Does the Loctite service procedure work for the Shimano Press Fit? Will the BB30 bottom bracket tools work for the Press Fit? I do my own service and I'm going to secure the tools to properly service my bottom bracket and try to resolve a persistent creak. Regardless of whether I fix the noise, I have 8Kish miles on the bike with no service on the BB. So I figure its time to go poking around, see what's going on in there, make sure things are well lubricated, etc.

Thanks in advance for any input!

Shimano doesn't make a press fit bottom bracket solution for BB30. They sell a BB for a wide shell 41mm ID. Shimano cranks can be easily adapted to BB30 and are prevalent on thousands of BB30 bikes throughout the world.
If you post your bike and model and your crank config, myself and/or others can propose BB solutions to quiet it down.

That's not what he asked.

OP, read this. Park Tools is the Voice of the Industry.

Yeah, it pretty much was. If Shimano doesn't make a press fit BB to fit BB30, then theirs can't be the same thing as B30, right? Good reply C4l. Informative and helpful.

The bike happens to be a 2013 Giant Defy 1 equipped with a shimano "press fit" bb. Cranks are Shimano R565 compact 34/50.

It appears that it is not the same as a the BB30.

Park Tool lists Shimano Press Fit for the BBP1 and the BBT 90.3. The BBP1 appears only to be a bearing press tool and the BBT 90.3 is the tool needed for pressing out the bearings, but contains bushings for pressing bearings back in as well. Do I need both? It seems to me that I could probably get by with the BBT 90.3 and a threaded rod, but I will probably opt for getting the press tool as well.

Remaining un-answered question: Is the Loctite fix for other press fit BB's also a fix for the shimano press fit?

Yes, I have some annoying noise I believe is coming from the BB. I have tried just about everything imaginable (or recommended here on BF) and am well acquainted with the fact that the noise could be coming from somewhere other than the BB. The truth of the matter is that its time for my to dive into the BB anyway so I want to properly service it and eliminate it from the equation. I have the Shimano service procedure for the BB and will follow that (as I type this, I am not sure if it recommends Loctite or not, but will most certainly check). The noise happens to be a persistent click/tick with each revolution of the cranks, sometimes alternating sides with the tick usually occurring as one crank passes top. Pedal are SPD-SLs and have not been serviced but are tight. Long ago, I had a different noise and I suspected the BB. Since the bike was new, the selling LBS serviced the BB. They happened to improperly torque the crank bolts (both were not torqued the same with one visibly not screwed in as far as the other) on the non-drive side resulting in a similar tick to the issue of today, but only on the non-drive side. They did not use loctite which I specifically inquired about. Properly torqueing both crank bolts (with a torque wrench) fixed the improper service and all was well with the world. I have checked the crank bolts as well. Suggestions welcome, but mostly I am interested in whether loctite is recommended with this set up since I might as well add loctite while I am fussing around with the BB.

Thanks again for the assistance.

If all you are asking about are the tools, that is a different matter. T he Park tool for knocking out the bearings, BB30.3 is reasonably priced on Amazon or ebay, and you can use the fittings from it with a threaded rod and nuts to make you own press kit for BB or PF30. For the 24 mm spindle you are asking about go on ebay for a cheap press setup like this one: 41mm ID Press Fit Bottom Bracket Installation Tool for 24mm Crank Spindles | eBay.

If you ever need to work on a BB30 or PF30 bottom bracket the fittings from the Park removal tool will combine with the rod and nuts from the above press to allow that.

Spec'ed or not, if you like quiet, go Loctite 609. Park BBT-90.3 is helpful kit but I wouldn't spend the $100+ on Park's threaded Presses. You can even use a large C-clamp with a block of wood on opposite side of BB shell. One cup at a time for squarest installation.

Thanks for the input regarding the Loctite Campag.

Pressfits are always going to creak. I replaced them on all of my bikes with these...no more problems...Wheels Manufacturing, Inc.

Mine doesn't.

Update:

Let me preface this whole thing by saying I still plan to get BB tools and service the BB including Loctite......

Last two days weather was warmer than usual and I hit the roads before work. In my continuing effort to eliminate the noise I cleaned, lubed, fiber gripped my seat/post and reset my headset (which has a tendency to develop its own tick/click) before hitting the road. Noise was still there during the rides. Oh well. Today during a morning trainer session I was yet again distracted by said noise. In fact, the noise has pretty much disrupted my last half dozen trainer rides since I slow down to try to hear or feel where it is coming from. Today I thought the noise sounded up high on the bike so I reached down while pedaling away and wiggled the rear brake cable. Silence! After 15 minutes it came back ever so slightly. Wiggle - Silence! Problem may be solved. This evening I plan to replace cables, clean the housings and sockets, etc and expect that should be then end of it for a while. Interestingly, I did this for both derailleur cables about a week ago thinking they could be the issue with no luck.

Yet again another episode of the noise is very likely not what you think it is....

If I am wrong on this - I still plan to work over the BB.

rpenmanparker 

That could be a mistake.

If the whole point of this thread is about finding an elusive squeak, make sure that your rear quick release is actually tight. I have seen many people throw parts at a BB only to later figure out it was a loose quick release.

The original post was about BB tools and Loctite use with the shimano press fit BB. the underlying problem to be fixed was noise - the two became intermingled for some inexplicable reason or simply because eliminating noise is a common reason to look into the BB.

"If it ain't broke, don't fix it" is sound advice. No doubt I will be back asking questions if something goes south!

Good Riding to All,

P.S. - I too have experienced a loose skewer causing a noise, but that was not the case this time.
