Oil seal ?

Hi Mark
I need a left crank seal for my 1980 DT175 after a main bearing replacement, about 4 years ago I used an IT175 double lip seal  - 9310225258 but now the same Yamaha supplier is saying they are no longer available. Do you have a different part number I can try? 
Cheers

CMSNL have them in stock.

Postage will sting, but not as bad as from the US.

Cheers, saw 1 left on csmnl but as you say postage is a killer. Got it from Fowlers last time but now unavailable

cheers, that number is replaced by the number I used  and is no longer available. I'll try another UK Yamaha dealer but looks like I might have to go with a std DT175 seal :(

Very odd.  I checked and several US dealers still sell it brand new (many times in stock) under the 93103-25125 part number.  Including CMSNL!

It also looks like you can get the All Balls 24-1073 crank bearing and seal kit in the UK which has the KOYO bearings and OEM seals...  about £40

Thanks for all the info, appreciate it and  seems like Ill be able to get the  IT seal from other places, weird that Fowlers say its no longer avaialble.
Koyo bearings are only £12 for a pair so it makes sense to buy seals individually.

Make sure you get the correct internal clearance rating on the bearings... C3? I'd have to look it up.
