Cracked The Cases Now What!!!!

[erikb45]

HEY BOYS,

I finally got the bottom end cases open. now what do i do- i checked for play on the connecting rod bearing and that is good. it needs to be flushed there are shavings everywhere they shouldnt be from the piston. i dont have a garage or a parts washer so i dont know how to flush the motor. should i just take it to the shop that will do the cylinder and let them check it clean it out adn reassemble the bottom end? or is there a way i can do it my self.


ordered all the stuff
complete gasket kit
75 over piston kit wiseco
head from yamahondaman ( which looks sick and amazing)
new ngk race plugs

have to get reeds yet.


i made it this far want to complete it the right way so it lasts, what else do i need any advice suggestions

thanx again

hey, maybe someone from the board lives close enough to you to help you out. with all these members, there has to be somebody close. yeah, it needs to be flushed out good. don't want to ruin the new parts. when I have to work on stuff in the field, I have a small air compressor that I use. Then I blow it out with brake cleaner, and then air again. Be sure to spray it with wd40 when you're done, so it doesn't rust up.

you could get a tub and some mineral spirits, then just pour it threw it and use a brush where you can. then hit it with brake clean and air as much as you can.

Make sure to Check your main bearings, If theres lots of metal filings, i would replace them along with the seals, There cheap insurance you wont blow your top end out....and more than likely due for them on a 20 yr old bike, Throw the Case's in the sink and scrub the crap outa them with some good dish soap, Blow dry, Best Clean your gona get, Just remember Steel/cast parts Rust and quick when exposed to the air, Throw a coat of oil on any you wash with water, Pressure washer works Great too!

ok first i dont know if she is going to let me wash the motor in the sink!!
ill have to do it when she goes to work (ha)

second the crank bearings are what ya talkin about right? theres no filings in the tranny part just in the crank area.

do i need special tools to change the crank bearings get the crank out?

and yes i have the manual

thanks keep it coming; you guys have taken me throught this whole thing so far

a Small propane Torch Works Best for installing/removing crank bearings, Have to heat the surface around the bearing race, should tap out, Just be Carful if you get the aluminum too hot it will crack, and then your really Screwed....Or you can take them to a shop and have them do it ( i would recomend you do),

[erikb45]

you might be right ill check pricing tommorrow. i would feel better if a shop put it back tpgether for me and checked it out.

helle people, called the shop today he said $60 for the bore job which seems like a good price.

he said to rebuild the bottom end would be $250 plus parts! that seems a lttle steep, what do you guys think? not much to rebuild just needs to be flushed change the crank bearings

[mike from long island]

most shops here are $95 an hour so $250 to reasseble your motor doesnt sound to bad of a price. will they make any guarentee?

[erikb45]

mike i only talked to chris "diggin racing" in ronkonkama for a couple minutes. when the piston kit comes in im gonna go over there with all the parts and see what i can work out with him. hopefully i can work out a deal.

[mike from long island]

not familar with them. good luck with it. i am just waiting for a few things and then i am going to get started on my 86 Z.

[erikb45]

im dieng to get this thing running again spring is coming fast!!!!

[BigRedBlair]

I here ya I'm in the same boat. taking the case with the crack and crank to the shop to have them put the crank in the other case. The right side case is still good so I lucked out there if I can get the stuck bolt out

money spent so far
flywheel puller $18
Gasket set $65 CDN
New cases $40
Right side for sale.

[erikb45]

did you get a price from the shop bigred. ithink its a little high but the assurance of experiance doing it might be worth it
