TY80 center Gasket

Recommended Posts

I am going to be changing crank bearings and seals on a TY80. Before I tear into it I would like to have my parts together, the only thing I am unable to figure out is if there is a center gasket or not. Did they just use RTV silicone or Yamabond and not an actual gasket?

So far this is my list of parts I will need: (if I missed anything please let me know)

bearings

seals

head gasket

base gasket

rings

crankcase cover gasket

Reed cage gasket

Thanks

on edit: I did do a search here, but was unable to find the info.

What about conrod & bearing? If was doing job i would split crank! And are gearbox bearings ok?

I have not split the motor yet, but so far all indications are that those are all okee dokee,

I will know more after I actually split it.

Just trying to get a little more info before tearing into it.

Thanks all.

Hi there

I've just done mains and seals on a ty 80 engine ....

6204 /C3 main bearings (go for a good brand )

Mag side crank seal 20x35x7

Clutch side crank seal 28x40x8

Front engine sprocket 25x40x5

Gear selector shaft 12x22x5

Sealant for centre cases

You might need a puller (or make one) to split the engine cases

Have fun :thumbup:
