First engine pull
Hi Guys
Well, I got around to pulling the engine out of a 75 bug given to us last month -- was waiting for a nice day and yesterday was it. Amazing how easy that is! The hardest part is documenting the connections (it is a FI model). Jan Anderson's trick of sliding the engine out the side seems so much easier than out the back -- it worked great so thanks again. I also noticed that the engine's top driver's side bolt is easier to get to by taking the left rear tire off. I could actually see the bolt this way - I had a hard time finding it, laying under the car. I'd like to open the case and inspect it, replace bearings, etc. I did notice some what-looks-like engine oil on the clutch plate, so this is probably due to a bad engine seal behind the clutch plate, right? What is a good way to make sure the case is not cracked? Also if (hopefully not 'when') the case needs to be line bored, where (near CT) would I get this done? There's a fair amount of rust on the tins and fan shroud. I've noticed some relatively inexpensive replacement parts -- are these advisable or should I clean and reuse the originals? This one is a FI model. Is there a way to test this engine outside of the car once I get it all back together? Lotsa questions - the first of many, I am sure. Thanks! Remco |

I also I can drop a bug engine using a floor jack with 2 stands in 20 minutes flat! ....and 15min flat if carb version - from the rear with AC -- takes 45 mins! > noticed that the engine's top driver's side bolt is easier to get to by > taking the left rear tire off.

What is a good way to make sure the case is not cracked? you must clean the case -- steam clean - then magnuflux case -- cracks will be at or around cylinder holes and oil pressure valve also check the (remove valves) heads in the same manner -- cracks will be at spark plug holes and or between valve seats -- > (hopefully not 'when') the case needs to be line bored, where (near CT) > would I get this done? > There's a fair amount of rust on the tins and fan shroud. I've noticed > some relatively inexpensive replacement parts -- are these advisable or > should I clean and reuse the originals? YES - just clean & repaint with hi-heat black paint. New sheet metal doesn't always fit properly > This one is a FI model. Is there a way to test this engine outside of > the car once I get it all back together? Yes, you can -- is a bit difficult You will need an engine stand to perform test -- and a way to attach starter, the electronic fuel pump and several devices that control the fuel infection > Lotsa questions - the first of many, I am sure. Bring'em on! BBA |

Wow -- thanks, Billy!
It took me a couple of hours to pull it out, but I was being very careful (which was probably not really necessary, in retrospect). I was particularly paranoid about bending stuff or having forgotten to unhook something but it all went without a hitch. Steam cleaning... That's a good idea because this engine is way beyond filthy! Was debating to power wash it, but steam cleaning is a lot better.. Also, would I just leave all the stuff on the engine as I get this done? (alternator, etc) Magnaflux? I've never had to do this, but I take it that stuff helps you find cracks? Any auto repair place has it, I take it? I did get the bugme video on rebuilding the engine and have several manuals - are there any other gotchas that I need to know? Especially since this one is fuel injected, are there specific FI things that I need to look out for? Thanks!! |

Before you attempted to pull the engine you should have dragged it to one of
those self service quarter (are the a dollar now) carwashes with the high pressure hose --- couple iterations and it would be free of grease, oil and loose paint. The aftermarket tins are crap - doubt they would come close to fitting a FI engine. ave them sand/media blasted and if you have extra $ powder coated (or buy Eastwood's kit and do it yourself). A machine shop can hot tank your block and heads and use blue dye to check for cracks - you want to have them checked out to see if the block needs line boring anyhow --- and ya need the valves at least lapped.

(alternator, etc) no -- remove intake manifold, alternator/Generator, distributor -- entire ignition system should be removed use a screw drive to break off all the crud -- then use steam cleaner device -- don't spray anything electrical > Magnaflux?

Any auto repair place has it, I take it? no - http://www.magnaflux.com goto: sales and find a dealer near you -- you want one can of their dry magnaflux. - cost per each can is not cheap! > > I did get the bugme video on rebuilding the engine and have several > manuals - are there any other gotchas that I need to know?

Make sure that you mark each piston rod -- each rod should depict the cylinder # as well the direction in the case -- create a mark on both the end cap and the rod to ensure that the cap gets back to the correct rod! -- Don't mismatch rod caps 3) Make sure that you remove all the main bearing as well as rod bearings 4) The alternator pulley shaft has a "half moon" key -- don't loose it! -- use a large screw driver - angle it -- tip is on pulley @ a slight angle. Use a large mallet, hit the end of screw driver handle HARD several times -- should come right off - a puller will take an hour to remove pulley -- screw driver method takes minutes 5) Have the crankshaft mains checked for size and roughened -- use 320 grit emery clothe - procedure is known as "crankshaft blue-printing" 6) use 10mm off-set wrench to remove oil cooler (2 nuts) don't use water to clean out - use gasoline only 7) There are 4 possibly 5 main bearing pins -- use vise grips to remove -- don't loose them!!! 8) make sure that you remove oil pressure check valves and their springs 9) your heads valve guides/seats were made for leaded gasoline -- have them R/R to Unleaded type 10) if you have the head rebuilt (I recomend that yuou do) -- have the exhaust valves replaced with new ones can't think of anything else -- BBA °?° BBA's RC Site - http://www.billybadassrc.com When Privacy Matters -- http://www.epic.org |
