Servicing '99 Bomber Z4 - replacement seals?

Just picked up a pair of Z4's from Flea Bay. They need a service, never done one before. I have the Mazochi manual, all looks fairly simple.

How will I know if the seals need replacing and is there anywhere cheaper than £16 a set from CRC?

Cheers,

16 quid is not a bad price, it is 4 seals in total, two oil and two dust wiper.

If oil is pissing through them or they are cracking.

Check bushings while you are at it if you take the seals out.
 
Thanks Fluffy, will they be noticeably cracked and leaking if they need replacing or should I do 'em as a matter of course?

Thanks Hamster, how will I know if they need replacing, or is it best practice to do it every service?

Best replacing both oil and dust seals at the one time. Chances are the dust seal will be damaged getting it out so best to order the full set and go from there

Fitting is easy but you must have a freezer ;)

Once youve replaced both seals(on both sides), changed the oil(choosing your viscosity) and torqued it all back together you wont need to do another seal change for about 7 or 8 years. Best swop out the oil say every 3 years and you should be right as rain :D
 
'Torqued it all back up'? - haven't seen any reference as to how tight they need to go back together?
