[QUOTE="ogrilp400, post: 16251, member: 88"] Two areas have been a right pain in the arse for oil leaks on my Comet. The back of the primary and the Dynamo drive. I have fixed the primary leak but the dynamo drive is proving nearly impossible. I have:- replaced the seal, replaced the seal again, smoothed and polished the pinion seal surface and replaced the seal, returned seal diameter to size, put two seals in there, put two double lipped seals in there, put an o-ring between the seals, gone to great lengths to make sure that the Dynamo shaft is perfectly central in the CC aperture by machining up an adapter to fit very neatly the shaft and the CC hole, fit and secure the dynamo then take out the adapter and fit the seals. Still the oil BUCKETS OUT! Phelps. [/QUOTE]
