I read the helms, and they say you need all kinds of bearing pullers and ****, i know my dad has them but i dont know how to use them.

I have bad bearings inside the tranny and i need to fix them by tongiht, i have a 1pm tuning appt at RLZ tomm. and there is NO WAY i am driving my brand new tranny 2.5 hrs on the highway with bad bearings......

so basically im looking for a DIY tutorial....

thanks for the help guys!

Pull diff.
grind a file to a 30 degree bevel.
have some brass or aluminum scrap.
keep a small hammer handy.
Grab bearing puller and wrench.



Use the file and hammer to carefully work the bearing off the seat so that you can get the hooks of the bearing puller behind the inner bearing race. Tap the file's edge in a little at a time on opposite sides like a torquing sequence so that you do not **** the bearing on the diff. If the bearings are truely hosed then you can pull/bang on them however you like. If they are not in bad condition and you want to keep a spare set around as a plan B then be careful to only pull on the inner race and not the bearing cage. If you pull on the cage then the the cage will break, needle bearings will go flying and you will have to try again.

Once you have worked them loose enough to get the puller's hooks behind then use a large socket to match the Inside Diameter of the bearing to use as a fulcrum and use the wrench to pull it the rest of the way off. Once off clean and deburr the diff if you gouged the mating surface. this can be done with the file and maybe some sandpaper. Sandpaper is awefully messy though. Grit is not good in a brand new custom transmission.

To put the bearings back on use a dull brass punch or rod of aluminum scrap and the hammer. Lube the bearing and diff, put the bearing over the diff. and lightly tap the inside race around the circumfrence until it starts to go on straight. Once it starts going you can tap harder and harder to work it on faster. Tap it until it sits flush on the diff. Do the same for the other side if that bearing too has to be replaced.

If it is being a royal pain then it can help to put the diff in the freezer and the bearing in a ziplock bag and put it in boiling water. This will make the bearing slightly larger diameter and the diff. slightly smaller diameter. You would have to work quickly as the parts get back to room temp the tolerance will get tighter. But use method above to work the bearing on. This can be frustrating. I have had experience with this in a few ways. Sometimes it is a giant hassle and other times it goes on like butter. Hopefully yours is the latter.

It should be easy to get the outer races out of the tranmission with the hammer and punch through the external axle ports in the transmission housing. Putting them in should be easy too. if they are hard put the transmission housing in a warm oven and the race in the freezer. That should get it together. The only bitch is getting the shims on either side of the diff's outer races to tolerance. You have to install the diff and bearings (you should leave the counter and main shaft out) and then put the transmission housings together and torque them. Then see if the diff has enough drag (specified as the amount of torque is required to spin the diff in the housing). I do not remember the specs now but the Helms manual has them or a call to the honda dealer service shop could shed some light.

If you assemble and it is out of tolerance then you have to take it apart and put in a thicker/thinner shim on one side or the other. Kind of like fitting bearings on the crankshaft. Repeat process. That is the biggest issue.

Once you have the correct tolerance install diff, then countershaft and mainshaft as a set, then reverse gear and fork etc. etc..

The precision shims could be a problem to find on short notice as well as the bearings themselves. but other than that if you have had the transmission apart then it should be easy to get it back together.

Keep us informed.

I take my diff's to have the bearings and VSS sensor installed. We had a bearing remover and managed to get the bearings off perfectly fine... but it ended up chipping a piece of the VSS gear. And guess what? You can't buy just the VSS gear separately.

I would call up some local machine shops and see if they have time to do it for you this afternoon. They should only charge about $50 bucks to do it.

 

If he just wants to replace the bearings on the current diff he should not have to screw with the VSS gear. It does chip easily but he shouldn't have to worry if he is careful.

I can imagine it looks like this:



He should have room to work.

I'm not an expert at this at all - but i thought there was some "hammer" type machine.

There's some kind of plate that is placed under the bearing - and a hammer-looking thing hits the top in order to set the bearing free.

Its called a slide hammer bearing puller. The puller pirate posted up top tends to be easier to use, not a sloppy.

You are right... for some reason I thought he was installing a new diff.

 

sounds good, thanks guys...

do you think the noise could be coming from the vss gear, i had to put the vss in before the tranny went in, maybe the teeth arent aligned right?? but it reads fine, the speedo works....

thanks

 

Did you put in a new throw-out bearing?

 

yup

edit: i will explain the noise im getting

its loud when im on the throttle or decelerating hard in gear, then i push the clutch in and it gets very soft, but its still there....

it sounds like gear whine, and gets higher pitched as i go faster...

 

Sent PM. Please do not link that vid. I am not hosting it. From your description it is probably gear whine. Where did you get the transmission?

Pirate

 

Have you spoke with Madness (seller) about the noise? I would hate to see you pull that tranny out to replace the diff bearing and it be something else.


It already had the LSD in the tranny right?

 

yeah i talked to him about it before but he said that he didnt think it made noise, im about to call him though....

I would. If you didn't change anything or crack the case open I don't see why it would just start making new noises.

 

if the tranny was on an all out race car they probably couldnt even hear it, whether or not its the diff bearings is hard to say, but if it was completely rebuilt w/ custom gears you would THINK they'd go ahead and put in new bearings.

any way you could just tow it there/back just to be safe?

 

well i got home from tuning last night with not a problem with the tranny, so i dont know what to say...

i figured 5 hours of driving at 80+ mph would kill it if anything would....

the only thing holding me back from thinking thats how its supposed to be is that when i brake hard with it in gear, it feels like things are grinding, almost like the axle splines could be skipping.....

it feels almost like something in the brakes, like a worn *** pad or a rock or something, but it only does it with the clutch out and in gear....

really odd...

but tuning turned out freakin awesome....check the thread out....

 

Drain the fluid and see if it has got a lot of crap from the gears/sychros wearing... Ususally an obvious indication of something wrong.

well it keeps getting worse sounding to me, i could be imagining, anyways madness and i are in the claim process with fedex so it should be taken care of to where i dont even have to deal with it....
