Ok, …both of these engines are notorious for the original grease to dry up to the consistency of cured concrete,…..the CV is by far the easier of the two to service, so I’d suggest starting with that one to get your feet wet,…..go slow, take pics, and proceed with caution, and you’ll be fine, ….you need to access the gear box to remove and clean out the dried crusty grease, or worse, if someone put fresh grease on top of the dried grease and now you’ll have concrete soup with chunky pieces ….I’d suggest reviewing exploded views ……fortunately, the CV mimics the old Prewar 700, or even the Postwar 773 as far as the gearbox layout is concerned….that dried up grease can really gum up those ball bearing inserts, so be mindful you’ve got them cleaned really well,….take note of thrust washer positions, and put them back as you found them….if you need to go into further details, or the gear box has excessive slop, you can contact me via profile for a more in-depth step by step procedure for setting up the thrust ( end play ) ……
many things to check, clean, and apply lube to as you go along…..including the motor and the wheels, axles and rods, ..basically, if it moves, it needs to be lubricated ….I’m not going to get into the great oil debate, it’s nonsense, but IMO, you can take all those Excelle lubricants and put them back on the shelf,…or dump out the contents and use the needle tip applicator bottles for some real oil….the three lubricants I keep in shop are 75-140 gear oil ( rods, rod bolts, and axle bushings ) 10W-30 ( motor shafts, bearings, etc.) and Mobil 1 grease …..BUT, you use what you like, and again, I’m not entertaining the great oil debate ……biggest thing is to have fun and enjoy doing your own service work!!….
