Inner Primary Bearing Failure

[dave]

Ok I spoke to my bearing specialist & these are specialised bearings for Harley. Can you give me the dimensions for both the bearings as there is the possibility they can make these bearings. Are they both roller bearings?

I have talked myself into doing my IPB. Especially with the August Denmark Rally and imminent high mileage looming.

Just been looking through my service manual (2006 fxbdi like yours ;-)) and have a couple of questions.

The IPB is the bearing in the crankcase??

Did you only replace this and the lip seal or the clutch bearing as well?

Did you replace the seals on the inner primary case bolts or did the tool you borrowed of the club to get the inner races in and out mean you only needed to remove the outer primary and clutch?

Apart from the inner race remover, did you need any other tools (ie the clutch locking tool)? Can you remember the size of the nut in the middle of the clutch?

Any tips on things to look out for, other things to replace while your in there or amount of time this may take much appreciated


Cheers, Roy

I think I've just had the same on a 2006 dyna wide glide, same symptoms. Got the bike trailored home and pulled of the outer primary to discover bronze shards all around the stator. Took the bike to Thames Valley Harley in Slough. Explained that I was very unhappy as the bike has less than 8k on it and only just out of warranty,was then told that they would look favouably on it. I was told that it needed a new stator but they were only £84 and the would probably go 50/50 on the cost. Nearly two weeks later I chase it up but was told they were still waiting for an answer from Harley. I then pointed out that they wern't going to contact Harley about it as they were going to sort it themselves, they suddenly remebered this and said that they were going to get straight on it.
Newt day I got a phone call saying it was ready, £284 +vat for the stator and with labour total £450. After explaing what they could do with there bill and the original discussion on pricing I got a phone call saying that it had been done at no charge.
So a result in the end but I suspect I would have not had a good result with standing my ground.
Small point but the bike was returned filthy, had oil and oily fingerprints all over the saddle and handlebars and had obviously been left out in the rain. Very shioddy for a main dealer.

Roy,

The inner primary roller bearing 9231 is pressed into the inner primary case and the inner race 34091-06 is pressed onto the input shaft of the gearbox.

I replaced this bearing only and the lip seal. The clutch hub bearing was fine.

I did replace the sealing bolts but might not bother next time. Cheap enough though. You have to remove the inner primary case to press out the bearing race.

The locking tool can be made from a 7" long piece of bar. You are not supposed to use the older type of stepped lock. You can borrow my locking tool.

When you come to pressing the bearing in, put it in the freezer for a while and put the case in the oven. There might be a reason why you shouldn't do this so chime in if anyone knows better. I did it this way and it seemed fine.

I can't remember the nut sizes right now but the clutch is the same as always but the comp nut is smaller than previous.

You will need the gasket between the crankcase and inner primary case, plus a few other bits and if you want to be really posh, the primary gasket as well.

I'll send you a parts list when I get back home.

Check stock before you pull it apart though.

It's worth checking your rotor as per jaguartvr's post. The bolts come loose and destroy the stator. I did as Phil recommended and put green loctite 290 down the threads.

Dave, there is a roller bearing and an inner race. I've got my old bearings if that's any good.

Parts list:
12052A OIL SEAL, INNER PRIMARY (Goes in inner primary case)
34091-06 RACE BEARING, INNER (Fits onto gearboxinput shaft)
9231 BEARING, ROLLER (Goes in inner primary case)
786A BOLT, SEAL x 5 (Fastens inner primary to C/case & G/box
60547-06 GASKET, PRIMARY COVER (Didn't bother with this)
34934-06 GASKET, PRIMARY (between inner primary and crankcase)
27444-00Y O-RING (To seal starter into primary)
60678-85 RETAINING RING (Circlip to locate bearing race)
63869-06 GASKET, TOWER (Gasket where shifter shaft goes through on mids)
HD-34902-B BEARING RACE PULLER AND INSTALLATION TOOL (Riders club)
1/4"x7"x1" flat metal bar to lock primary.

When you come to put the inner primary case back on you might find there are no dowels to align it and nowhere to put them anyway so use the outer bolts wrapped in tape to pack out the mounting holes until the sealing fasteners are tight.

It sounds much worse to do than it actually is. Worst bit for me was getting the parts. Give me a call if you get stuck.

Parts prices from Harley Chesterfield
Don't forget 5 bolts needed

Cool

I have spoken to Andre and he is going to supply me with the stepped tool to lock the clutch and the bearings tool (he looked on his records and found the one you'd taken out as I wasn't sure at the time of the part number etc)

So good to go. Have emailed Cheltenham HD for a price and lead time on parts and plan to do this weekend after next (this weekend is 20k service and steering head bearings, does it ever stop )

Thanks for your help mate, will bear everyones input in mind

Nicholas, f'in hell - £31 for a outer primary gasket (or bit of paper as Peter called it). Jeez. Thanks for the heads up mate. Other than that, the prices look okay actually. Just labour, for me thats being sat on my arse in the garage working on my bike - result alround!


Peter when you say you pressed out the bearings etc, did you use the tool fom HDRC for that?


Cheers, Roy

H-D don't advise using the stepped tool on later models. They recommend the bar. Don't know why.

The primary gasket is a crazy price so thought that it's worth the risk. Easy fix if it leaks.

Pressing the roller bearing out needs the use of suitable size tubes and threaded rod. I found a socket that made good contact with the outer race and a short bit of tube to put on the other side. Tightening the nut on the threaded rod will press the bearing out of the case and into the space made by the tube. Can be a bit of a pig this but just be carefull not to stress the case. Maybe a local engineering firm could remove and re install it for you?

The inner race is fitted so there is a gap between the inside of the race and the output shaft bearing. It tells you in the manual but I took measurements before taking the old one off just to double check.

IF IT GOES ON TOO FAR YOU WON'T BE ABLE TO GET THE EXTRACTOR BEHIND IT. BIG PROBLEM THEN.

Sorry Roy, didn't mean to shout, just trying to save you from any grief.

Really looking forward to that one And here's me thinking all I had to do was change oil and plugs and stuff. Now I am up to my eyes in service manuals. Still I guess thats what HD ownership is all about
