Hello - I have a '93 SPI MINI imported from Japan to the US and I have a leaking injector. I've got the injector out of the housing and I'm struggling to find the correct O ring sizes for injector.

 

I haven't found them listed in the normal places I use on the net to ship to the US and just 1 ebay ad from the UK. I'm really trying to find a US source. I'm sure they are just standard viton O rings.

 

Can someone tell me what the sizes are?

 

Thanks!

Interweb says the Bosch part number for the injector is  0-280-150-682. Maybe you could cross reference it to something that was more common across the pond?

Google chucked up 1 280 210 769 & 1 280 210 746 as "rubber rings"  supplied with the above injector.

Thanks

 

The internet doesn't help. I know what the part numbers are and because the injector is obsolete, the bosch part numbers for the o rings are equally obsolete.

 

There's youtube videos about changing them and there's people on ebayuk selling them, but no one seems to want to publish the sizes. I don't know why it's a secret.

Is this any help? Or is this the eBay listing you refer to above?

I had a similar problem with v8rover seals.My local garage has Bosch signs outside so I tried him.He matched me a set from an assortment of seals from a kit of spares.Worth a try?Steve..

The seals in the link above are one option. Classic Mini NLA used to sell them...still might. I've found nothing on the US side. I am in NJ so maybe we 2 sets and save a smidge on shipping/tariffs?

 I ordered them from the ebay UK link. I ordered 2 sets so I had an extra one.

 

I'm fairly positive the lower one is 7mm id x 12mm od x 2.5 CS. I ordered 4 of those from a place in GA that should be here today.

 

I ordered a Viton o ring kit from amazon, but none of the 7mm o rings are larger than a 2 CS, so they aren't thick enough.

 

If we knew what the sizes were there are a billion places to order them from. I couldn't find any specifications related to the Bosch part numbers.

I would appreciate it if you could take a measurement of both o rings, thanks in advance.
