FD3S Rebuild: Take 1
« Reply #15 on: May 27, 2004, 12:47:41 AM »
Now only one other thing worries me. It is the amount of wear on both stationary gears inner eccentric shaft bearing surface. There are no scraps, scratches or gouges, but it does seem to have worn through some of the white metal plating where the engine would usually lay to rest once turned off. Meaning that it has worn from the eccentric shaft winding down on to it due to gravity once the engine has been turned off and has obviously had a lack of oil around them.

Can anyone tell me if this looks normal or ok? and if not is it possible to get new bearings pressed into the stationary gears?

Hope you\'ve enjoyed the first installment:D

Kind Regards,

Paul:)

I personally would not reuse that bearing as there looks to be quite a bit of "brass" showing.  Yes, you can press a new bearing in.  I use the Mazda special tool and a hydraulic press.  The bearings are very easily damaged, so I would either find a shop that specializes in rotaries, or buy the special tool if you are going to try to do it yourself.

Glad to hear you took the plunge paul.....  not too hard when you get stuck in.  Make sure though you get the parts checked before rebuilding.  I did all the measurements and inspection, but when i took em to pip he took one look and scrapped em  :(  he was right, there were bits i missed but a specialist will know what they are looking for.  I ended up having new rotor housings and plates.  Mine are being ported as we speak and i will be picking them up on saturday with a bit of luck.  

You can pop round one night and have a look if you wish.   Have you git your rebuild kit yet?

Cheers

adam

Thanks for the kind comments guys; keep them coming;)

Yeah i think i\'m going to take all the parts into University to get them measured properly using all the correct equipment. Hopefully everything will be ok as the rear rotor still had very good compression before we stripped it and there appears to be no chips on the side plates just a little wear. And no we haven\'t got the rebuild kit yet, but would definitely be interested in calling round sometime to check over what you get in it and to also look at your project:cool

Cheers, Paul:)

P.S. Anyone know the part numbers for the stationary gear bearings that the eccentric shaft runs on? how much are they? and where can you buy them from? and/or do they need to be a specific size to compensate for the eccentric shaft wear? sorry bout all the questions:rolleyes: :D

Part numbers are NF01-10-E04 to NF01-10-E26 in ten steps from 1.980mm to 2.000mm. I assume that\'s oversize. They\'re about 40 quid plus VAT for the pair (front and rear)

Personally, I took mine to Pip who pressed a new set in for me.

Cheers for the info:) What size did you get? just the standard ones? I think usually you\'d only get over sized ones if the crank/shaft has had a regrind and how much did pip charge for pressing them in etc?

And regarding the dirty southern rotory guy (Brent) :rolleyes: It is a long story m8, but basically we were just going to take the engine out and then he had arranged to send the block over to america to get a rebuilt exchange one back with stage 3 porting and race bearings. Anyway due to it being relatively cheap for what he was promised (mainly to do with the weak $ at the mo) my friend sent off his money, but never recieved the exchange engine and had had no e-mail replies back since apart from ones with excuses saying that the engine will be ready next week then the week after that, after a while the e-mail replies have stopped altogether:(.

A lawyer is now on it as another guy from Norway is in the same boat. The weird thing is that a few people in the US have had engines from this guy, maybe he just thinks that if the customers are outside of the US then he can get away with scamming people:reallymad.

So the moral of the story is don\'t trust ebay or dodgy americans without having a lot of positive feedback regarding their legitimacy. My friend has lost out on over £1600    :eek:

You live and learn, Paul

ouch!

Not sure what size mine are tbh I gave Pip all of the parts and he measured tolerances, ported and skimmed the plates and fitted the bearings. I\'ll try to dig out the invoice and get back to you.

Ok here are some actual pics of the build:cool
