Hi Guys,
Thanks for your replies - most appreciative.
It sure seems that the catogorizing of chains appears to be very challenging to get information on.
To answer some of the comments.
1) I have sent two emails to Buhler about the blower and have yet to get a reply. They could be weeks in answering - who knows.
2) Sometime today I will go with a set of caliper and measure the chain - possibly remove the joining link for accurate measurements. That should at least give me the main dimensions.
3) I still have to remove the chain guard to get a close up look - I might be able to get some further info when I do.
4) As best as I can tell after spending hours googling on the net, it seems as if the RC-88 might just be a British Standards number - a bit like ASME etc. That would just cover the standards for that type of chain and not be a size number.
Yes, there is a bit of work to do and being a "stubborn old sod", I will keep at it until I can get some real information that I can pass along to anyone who is interested.
Going on memory, I think my chain has a pitch of about 1" or longer and is close to 3/4" across (width?). I will find out for sure sometime today - hopefully the outside temperature will climb to around 0F or -17C or if I am real lucky, get even warmer
Anyways, whatever I come up with I will certainly pass along to you guys.
Thanks for all the positive comments and I apologize if I have come across as arrogant.
Cheers
Jim
