I decided to trove the flywheel and just voted it all back together… but I have bought the wrong one or the is one is not standard. I bought a 200mm fywheel - the clutch seems to be 215 so don’t go in the new one. Is it the wrong flywheel for a type1 bus engine ? Can injust get a 200 mm clutch it and sap it together -the old one is a bit worn any way so was thinking of replacing it anyhoo. Can you get 215mm flywheels? WTAF is going on here!!! Should I have measured it before just randomly buying things and finding this out earlier?
Earlier buses had a 200mm friction plate, later ones had a 215mm. A 200mm setup will work fine, so just buy a 200mm clutch.
It’s all back in and together and it runs. Still have oil dripping from somewhere…. Consider this ….. if maybe the sump plate nuts were all really quite loose and one was missing - that wouldn’t give a similar oil drop pattern to if the main seal was gone - it wouldn’t right? Why am I such a looser…..
It wouldn't. Have you got all the gaskets on the sump plate? All nuts (which ideally should be "acorn" nuts with crush washers under them)?
Yes the engine is installed slightly nose down so the oil runs forward and drips from the same place. Mine drips slowly like that, needs a new gasket set, but as I have a centre oil drain plug, I dont touch those nuts. Its in my spares collection to be fitted.. A missing stud is even more exciting, the top bit is still in there or there wouldnt be any oil left.. But the studs will leak down the threads. Possibly might wobble free and vanish then you suddenly run out of oil. Dont over tighten the nuts, either the studs snap or they strip the threads in the engine case. In which case stepped studs need fitting. . Extra sealing is to use reusable Dowty hydraulic seals in place of single use copper sealing washers, and use acorn nuts on the ends of the studs. Lying under your bus wearing a head torch and safety goggles looking up can be quite informative ! Nearest miss was a a big glop of leaked gearbox oil and dirt that dripped out of the gearchange coupler onto my cheek while I undid the old pre-gearbox-recon shift coupler.
Not really, no. Seal is further forward. You already know you need a rebuilt engine so just put up with the oil leaks while you drive that one into the ground. If it's offending your garage floor, park a drip tray under it.
I have ordered some acorn nuts and will squirrel them away to be fitted at my convenience. I have crush washers in a seal kit so will put them on - it’s go to help the oiliness of it all. I think what has become clear, is that my complete lack of care and maintenance of our poor old van makes me an underserving keeper. Never mind though eh…
