  1. Designed rear axle sleeves to have Suzuki Jimny rims and tires be a direct fit to the Big Bear.
  2. I designed a Big Bear rear axle sleeve that fits over the axle's hex nut, acts as a 40mm spacer and has a flange and a hex head to mount Tamiya's Suzuki Jimny wheels to. Keeping my fingers crossed that this will work! But knowing me, I got mt measurements wrong someplace...
  3. Very cool! I have to take apart the transmission and get an accurate count of the teeth on the diff.
  4. Three out of five packages ordered arrived today, the other two due by Friday I think. Two sets of Tamiya monster truck tires - Lunchbox wheels and tires as well as Suzuki Jimny wheels and tires. Also arrived are the two pieces I had 3-d printed, a new bumper for the Big Bear and the front body mount. The body mount will work perfect, not sure how I feel about the bumper... seems a little weak and a bit ridgy?
  5. @waterbok I'll try to get that info for you tonight, if not tomorrow night. Thanks!
  6. I go through phases with this sort of thing. I've spent more money in the past two weeks on parts and pieces than I did all last year. There was a span in there where I didn't spend a penny on RC for the better part of 5-6 years. Growing family, other projects, honey-do lists, etc. Right now I'm at the peak "get it now before it's gone!" phase, just spending like it's never going to run out. I'm 99% sure I have enough projects to keep me going for quite awhile... but every time I see a Sand Scorcher or Big Bear parts, I get this weird little twitch to reach for my wallet. And God help me if Kyosho re-releases the Turbo Optima. I might not be able to resist!
  7. Couple of notes: the 480 might be a goner - it spins well and all, but the two leads have come off over time and took a good amount of the contacts with them. Maybe salvageable, I don't know. Reassembled the rear end and transmission without any issue; the ball diff is smooth and silent - but when both axles are turned in the same direction, there's gear chatter and it occasionally locks up. During assembly, the pinion gear looked a little small to me, like the teeth wouldn't mesh with the spur gear well. So I'm going to have to disassemble it and do a little more checking of pinion gear teeth and numbers and such I think. Oh, and the windshield is toast - anyone know where I can get another? Thanks!
  8. Yes, that was Dawn. I have heard that it promotes rust, but I made sure to do a light coat of machine (3-in-1) oil over the parts before they went back together. Hopefully that will do the trick. That's exactly what it is! I have no knowledge of them at all. Is it worth keeping? I was going to try out the M480-RS that I have from my original BB in this truck...
  9. @Crash Cramer Funny, I just ate in one of his restaurants Friday night, never even thought about it! Yep, came with the differential. pics of everything are over here:
  10. Cleaned and inspected all the plastic parts for the Triple B project, also took apart, cleaned, regreased, and reassembled the MIP ball diff that came with it.
  11. After thinking about it a while and seeing as the grease that was in the ball diff was more like glue after sitting for so long, I figured it should be degreased, cleaned, and then re-greased and packed with silicone grease. I was a bit nerve wracked with teeny tiny ball bearings on the loose, but everything went fine. The diff is now smoother and quieter than it was before. It was actually very easy to take apart, service and reassemble - I was pretty surprised. Before With the spur gear Stripping the grease off Starting reassembly And after
  12. Big Bear metal parts soaking in a mixture of white vinegar and salt to help remove corrosion and years of gunk. It's actually doing a decent job.
  13. So I have been trying to think of a solution to amend the problem I have (or anyone might have) with the lack of re re tires for the BB. I ordered a set of Wild Willy 2 wheels and tires and a WW2 E-parts tree which has the hex hubs for the axles. I know that there are plenty of adapters out there for converting a Big Bear to Blackfoot wheels, but I don't want to go down that road and make this a "Black Bear" - although that sounds pretty cool - so I am going to go to work on fabricating Big Bear to Wild Willy 2 hub adapters. Before I get super involved with this, they don't already exist someplace do they?
  14. And this is why you shouldn't post from your phone late at night. Sorry everyone and thanks for the pick up Waterbok!
  15. I'm likely not going to be taking the ball diff apart, just giving it a really good cleaning. I have a couple of pics of the assembly instructions from MIP from the diff was originally built. Also, here are a couple of shots of the diff , idler gear, and the spur gear on the no-name motor. The squares on the cutting mat are 1-inch square to give you an ide of the diff' size.
  16. I wish I had a sonic cleaner. Wonder if hydrogen peroxide would work? Or vinegar and baking soda? I found 3-d files online for the bumper, body mount, roll bar, and lights. Had the mount and bumper printed. Should be receiving 3-d printed parts from a local source in a couple of days. Great price, looking forward to seeing what they're like!
  17. Well, that Big Bear I got of Fee Bay a few days ago now sits disassembled on my bench. Easily the filthiest model I have ever taken apart. Dirt and sand everywhere, very sticky dust, dead spiders in the tires, thick, lugubrious grease in the gears. Many of the bolts have corrosion on them. The tires, while being in okay-ish shape all have multiple flat spots. The tire inserts had their lips bent, almost like scallop shells - how do you do that? You'll see in the picture that one of the screws is not like the others - someone just jammed a screw that was way too big into the back of the wheel. Nice job. I'm guessing that when this was put away the last time it was run hard and put away wet, so to speak. Whatever double sided tape that held the ancient receiver in place was clearly made out of the material that they make the little black boxes out of that are on jets. Wish the whole truck was made of that stuff, it'd last forever. Oh yeah, the front body mount and the bumper were broken. However I'm not deterred. As I go along, I'm sure I'll have questions... as a matter of fact I have one now - what is the best way of cleaning small metal parts? I was thinking of soaking them in mineral spirits or something similar, but not sure. Could always dowse them with Dawn dish soap and near boiling water. Was wondering what everyone else would do? Also a serious plus came with this Big Bear - an MIP ball diff. So the transmission won't bean issue. I hope.
  18. Funny, I've purchased several new vehicles; a FAV, an Optima, a Schnitzer BMW, and a WRC Focus and have only built one so far. While it was fun, it is so much more gratifying to either fix up the ones you had as a kid or to find the beat up car/buggy/truck that speaks to you and rebuild it. All the gear that I bought prepping to build the Optima I bought last spring is going to sit a while more I guess. There's a Big Bear on my bench at the moment.
  19. Hi Chevelle -

    I was  inspired by your build thread here: http://scalebuildersguild.com/forum/showthread.php?22719-Marui-Big-Bear-Rejuvenation  and went online and bought and am going to begin restoring a Big Bear.

    Well, the one I got is in pretty good shape except for - you guessed it - the tires. I really like what you did with the wheels from your build and would very much like to do the same with my own. Could you tell me where the tires you used came from and what wheels you used?

    I really appreciate any help you could provide and thanks again for the inspiration!

    -Mike

  20. New 13T brushless motor and ESC from China. Arrived early too!
  21. Mods, I'm not sure if this is the right place for this topic. If I put in here by mistake, my apologies and please feel free to move where it belongs. Thanks. Finally got to take some pictures of the ads in the old RCCA mags I have. Many were repeats so I picked the ones that caught my eye or sparked my imagination when I was a kid. If there are any ads that you remember but haven't seen since 1986 or 87, I'd be happy to look through the magazines I have and add them to this thread. Heck, if anyone has any old Tamiya ads or just ones they always liked feel free to add them in here too. I wanted this winter set up in the worst way when I was a kid! Dot matrix printer ad - how low a budget did they actually have?
