Re: Modding the center housing
 

sweet, got my tools out and about to rip this bitch apart and see whats up at the hobby store this week.

thanks man

Re: Modding the center housing
 

tdo4 and tdo5 should be the same right?
i might have to give this a go.
my p.o.s. turbo can use all the help it can get.

Re: Modding the center housing
 

wait you used a smaller turber then im planning on doign it too, think the td04 shaft would be the same diam as a the T3 shaft?

Re: Modding the center housing
 

Hmmmmmmm, what a coincedence. I was at a friend's house last night and he's been tearing down an old R/C helicopter his ol ladies dad gave to him. He said man, this thing is chock full of ball bearings. Just so happen to have a tower hobbies catalog too. I might look into this as well. I gave him my old blaast 50 trim for helping me out with swapping on the new 60 trim. We might tear that 50 trim down and give it a looksee....

Re: Modding the center housing
 

------ hell, im going to go rip apart my two broken 16gs.

OK SO, i got em apart and im looking at the bushings, the brass bits are a bit scored but for the most part are in good shape. So the trick is to what replace these bushings with bearings that match the od and id?

Re: Modding the center housing
 

when ordering bearings, they will be listed as (EXAMPLE) '5x11' which is the INSIDE x OUTSIDE diams. the last # is the width (usually 4mm)

Re: Modding the center housing
 

Update: Got a bearing to test fit, stupid thing was 11 dollars ... ID is to small and OD is super super close. The bearing itself is super narrow so im going to bore the bushing out an duse it as a spacer. The other thing im wondering is how to setup the bearings to be bathed in oil, both cages are open faced so i figure as long as its not directling lined up with the oil holes theyll get oil. Ill machine the turbo shaft msyelf to get it down to fit the bearings :D

OD of journal is 16mm ID 9mm, width is 9mm ,Ballbearing OD 16mm ID 8mm width is 4mm

IF the bearings werent 10 bux each id stack 4 of the bitches in there.

The plan is this: I'm going to put the shaft in my drill, im gonna spin it and sand it till I take 1mm off the shaft. I will then slip 2 bearings in. Any ideas for the 4mm spacer im going to need? Id rather not stuff it full of fawking bearings at 10bux a pop. 40bux isnt the hmt way.

Blaast you should go ahead and balance this for me for free since im so awsome.

Re: Modding the center housing
 

------- OD of the bearing is slightly to big, like barely.... piss me off.

Re: Modding the center housing
 

Dry ice press fit?

Re: Modding the center housing
 

I thought bout that, heating up the housing and freezing the bearing

Re: Modding the center housing
 

You don't want to add more bearings then you have to first of all. If you can't make a spacer just use the outside cases of 2 bearings for spacers.
I want to see how this works out I have a played out .42 .48.

Re: Modding the center housing
 

What i could do is only machine the depth needed to keep the bearings flush, and this will also keep the oiling holes unblocked and dousing the centre with oil. The other option like i said before is to bore out the old journal bearing so theres no contact with the shaftand use it as a spacer. The problem with that tho is that it may block the oiling holes since the journal bearing wotn be spinning at all. So really the first way is the only way to do it.

Re: Modding the center housing
 

Hmmmm I have some machinery and a pair of t25's ..... temped to try this on one of them and run some tests.

Re: Modding the center housing
 

Do it!

Re: Modding the center housing
 

Im down to try this, To bad I don't have any non bb turbo's laying around..

Re: Modding the center housing
 

VIDS!!!!!!!

Re: Modding the center housing
 

I'm stuck at finding bearing sizing that isnt gay. Mostly OD stuff so i dont have to machine the stupid housing.

Re: Modding the center housing
 

did you use brand name measuring instruments to find the sizing?

Re: Modding the center housing
 

The calipers werent super accurate, but the main problem really is finding a bearing that will spin at 200k and not ---- the bed. I'm waitin for my machinest buddy to bring his tools over and take proper measurements to a few thou at least.

Re: Modding the center housing
 

ceramic bearings can be had easily

Re: Modding the center housing
 

Priced them, they seemed to only come in Metric sizes and in 2mm intervals. Not to mention they are fawking 80bux!! Way to much for a 14b lol.

Re: Modding the center housing
 

link to the bearings?
