Report Viton oil seals? in Bultaco Posted December 2, 2011 I was wondering has anyone used viton oil seals in a engine rebuild ? I use them every day in pumps and mixers in chemical works and they work well and out last the bearings. But the only downside is they groove stainless shafts more than nitrile ones do. Just a question to see if anyone has had a go before I do.

Report Beginner bultaco owner 159 in Bultaco Posted December 1, 2011 Thanks for the help everyone. I will get the micrometer on the piston in work today. I got the case split last night in work and it doesn't look to bad. The engine number is a 159, matching numbers. It needs new rod bearings so I'm going to make a jig for splitting the crank and re pressing back together. I will get some pictures up on hear soon. Unsure what to do with the frame yet. I was thinking of ripping off a puma style bike but I'm not sure yet? Any idears would be a great help Thanks again Ben
Report Beginner bultaco owner 159 in Bultaco Posted November 30, 2011 Hello to all I've just purchased a bultaco 159 project, which needs a hole lot of work. It's stripped now and I'm working out what I need. I think it's a 350 can anyone tell me the piston diameter so I can work it out for sure. Thanks Ben
