[QUOTE="Ol'89r, post: 1473620, member: 17212"] Cool, it's good you got tools with the bikes. These things are not that hard to work on with the right tools. Heck, even Gomer could do it. One important thing to consider with a barn find. Triumphs have a sludge tube in the crankshaft. This sludge tube is designed to capture all of the swarf in the oiling system. (Dirt, grit, metal shavings, etc.) The oil enters the crankshaft and goes into the sludge tube. By design and centrifugal force, the sludge tube captures the swarf in a semi-solid state and lets the clean oil go to the rod journals. When a bike sits for 30 years or more, the sludge in the sludge tube will dry out and become solid. When you start and run a Triumph that has been sitting for that long, there is a chance the sludge will break up and go into the rod bearings. This will result in damaging the rod bearings and usually the rod journals. You have two options... Take the engine completely apart and clean out the sludge tube. Measure everything, install new rod inserts and anything else that is not in spec. Then you will have a good solid engine that will last. Option number two is to go ahead and run the engine and hope for the best. You may be able to get away with no problems but if the sludge gets into the rod inserts, it will damage the inserts and most likely damage the rod journals on the crankshaft. In which case you will still have to disassemble the engine. Rather than waiting until your rods start knocking and having to regrind the journals, or worse yet, throw a rod through your cases, I prefer option number one. If you want to pick one and tear it down, I can walk you through it. [/QUOTE]
