So Bike #2 is a mess, at least on the outside. I’m the type of guy that before I rip into the head to look at the valves I’m going to wash down the bike, but I guess others don’t feel the same way. I talked about the bashed in case so I thought I should post a picture of this (post initial clean-up):
Looks like the cylinder heads for this purchase were both good, though all 3 suffer from exhaust stud molestation. But that should be fixable. Why people don’t invest in a $10 bottle of high heat anti-seize I will never know…I guess it could be some knurly rock damage but whatever.
PO went to town with the black spray bomb. No masking, no dis-assembly – Just spray it. Again this is no problem to fix it just takes time and patients…Man I’m whiny today
Insides look nice, removed the whole top end, both side-cases, rear suspension
and wheels. Went to undo the swing arm bolt – seized to the bushings. As many people know this can be a real PITA. First I tried the easy things: penetrating oil over night, drift & hammer, little bit of heat, 2-slot flywheel puller (frame-to-slots & bolt-on-bolt). Nothing!
Okay now the hard way: Angle grind the head & stub of the bolt off, drill out core with progressively larger drill sizes, heat, drift & hammer, heat, drift & hammer, penetrating over night, heat*, drift & hammer. Finally I get enough movement that I can drop the engine & swing-arm assembly from the frame. Once on the work bench the angle grinder makes quick work of the other 2 required cuts and I can slide the parts out. As Murphy’s law states, after all that work (& heat) 1 tap of the left over bolt in the vice and the bushing drops off
. * yes I am aware of the danger of heating an area that has fresh penetration oil. I had lots of ventilation and a big bucket of water sitting there
Disassembled the crank halves for bike #2 -All looks good inside, some bearings gone but I’m replacing the lot so that’s fine. Gear box is a little warn
(like the other one) but it should still have lots of life yet.
Well now what? Time to start getting the engine parts on order and get things cleaned and back together. I did a bunch of parts washing and coated parts in oil for storage until I’m ready for them. Cleaned out some of the oil strainers
Ran into an interesting problem as I went to order oil seals for the case; there is an oil seal behind the left bearing for the counter balance. I have it in all 3 cases but I cannot find it on the parts fiche.
Most other parts are on order now – Bearings, seals & gaskets. I have to get the parts all cleaned up and ready to go back together. I am starting to make a collar so that I can pull off the cam gear without damaging it. I will get picks of this soon
