Hello all

I finally have my 87 Tundra up and running - thanks for your advice, comments, and suggestions.

I have ordered a shop manual and should be able to keep on top of things more readily once the manual gets here.

I plan on tearing my Tundra down this summer and checking over every nut, bolt, bushing, etc. to ensure that I do not have any suprises next year while out on the trail. I was wondering if anyone would be able to offer their words of wisdom regarding this project. Has anyone ever rebuilt a Tundra motor before? Are there any problems that I can expect or should watch out for?

Thanks all!

All I have and ride are Tundra's. I haven't rebuilt any of them though. One thing I would suggest...and I dont think an 87 had it is to ditch the oil injection and just mix it. Too many bad things have happened with this setup...it aint worth it!

Yep .... my driven pulley support wasn't as it should be, which resulting in my chaincasing cracking .... that further resulted in my engine support bracket snapping. I changed the chaincasing and had the bracket welded, with an additional piece welded on for extra support.

Just to make sure, this summer I am taking it right down and building it back up again so that every bushing, bolt, and bracket is guaranteed to last. Last weekend I walked 8 or 9 miles back to the truck, so I figure better safe than sorry.

All I could tell you is I had one and it was GREAT...probably won't find much wrong with it. One of the Top 3 all-around best sleds ever made!!!!

Hi RotaxAtax

That is what I have always heard and when I decided to get my own, a Tundra was a natural choice. I figure that once I have this one all figured out in terms of required initial maintenance (replacing worn parts, etc.), then with regular maintenance thereafter it will see me through many a trail.

I have 3 Tundra's, 2 newer and an 93. The 93 you can point vertical and it will go....and finally dig itself in. The newer ones you can point vertical and it will get to a point where they will just power out, without breaking loose. We need to find out why and can't figure it out.

I was riding in bottomless powder the other day, I was breaking trail for the big sleds. ;) IT ended up like putting your truck in 4th great at 5 mph and flooring it...nothing! I removed all the pucks from the clutch last year, thought it helped. I think I even had the primamry spring tightened one notch.
Sure wish we could figure out why these new ones wont break loose in a situation like that.

Another thing I just thought of with that era Tundra.

BE SURE your motor mounts are tight and not cracked. I have seen a few where they rattle the mounts loose and shift and wipe out the crank...that fast.
