My truck isn't shifting into 2nd gear ever. At first it would only do it when the gas was starting to get low and more recently not at all. I have taken apart the gear cover and clean the OWB inside and wiped down the cam and bushings. They are filthy. Still nothing. Any suggestions to help?

Thanks,
Mike
 
Not sure if the LST2 is the same as the LST1, but check the surface where the 2nd gear clutch makes contact, this may have glazed over, and check the 2 clutch shoes and pull them apart manually to make sure they arn't stuck together with dust.

check your tune. when the tank gets low it runs leaner, so the rpms are going up allowing it to shift. if your motor isnt reaching a high enough rpm, it wont shift. if your tune is "spot on", then there should be the shift point adjustment somwhere by the tranny(i dont have an lst)
 
your throttle or tune is not set correctly when your truck is running low on fuel it leans out a little so when you have your truck runing do a couple high speed passes then take a tuning screwdriver and lean your high speed mixture and then if neccesary lean or richen you lsn (low speed needle) then your truck should revv higher

and remember to tune your truck EVERYTIME you drive it

Or, the LST2 was known for sticking two-speed shoes. Take the screws out of the shoes and inspect the springs on the screws. They are tapered at one end, that is the end that goes under the head of the screw. Also, reaming out the unthreaded holes in the shoes will help keep the shoes from hanging up on the screw itself. Don't ream too much, just a hair.

Would two bad bearings in the clutch bell be any influence? I just took the clutch bell off to look at the shoes and both bearings look bad but I am not sure. As for reaming, are you referring to the "eye" on the shoe that the spring goes inbetween? Sorry, beginner here.
 
Well, bad bearings on the CB would cause heat and other issues, but not highly likely your issue. If not taken care of, they will grenade and more than likely destroy your spurs as the CB flops around like a lame duck. If they feel gritty and the inner race has noticeable wobble to it, then replace them. FastEddie (forum sponsor) sells bearings at $1 a piece and shipping is reasonable. Just buy 10 rubber shielded and keep them on hand.

As for the shoes, I'm talking about the shoes in the two speed itself. Not the ones on the engine, the ones in the inside spur gear.

Part # B3404, the half moon things. Ignore the circles, that was for someone else.

The screws that go into those shoes go through the shoe on one side and thread into the other shoe on the other side. So, they kind of create a slide by letting the shoes slide on the screws. The holes that "slide" may be a bit too small and hanging on the shoe itself. So you very lightly ream those out. Also, the screws have springs on them. The springs are tapered at one end. The tapered end should go under the head of the screw or it could also hang on the screws as the shoes slide.

I believe the stock setting for the two speed shoes is to screw the screws gently in until the spring bottoms out and is fully compressed, then back each screw off 4 turns. Be gentle when screwing the screws in as to not permanently deform the springs.

As with many things RC... it takes 2000 words to explain something you can be shown in 30 seconds. ;)
 
I appreciate the diagram as I was way off base as to what you were exactly referring to. I will ream slightly though while I have it apart. Both bearings inside of the CB were faling apart when I took it apart so I will be replaving those as well before I get driving again. Also, think my tuning has a small part to with it. So I will address that after I get these parts situated. Thanks again for your patience and help.
 
did you get your truck sorted i bought one new last week and although i replaced my clutch its still slipping in and out of gear already broke 2 drive shaft pins front and rear i think i have the same problem as you what did you do to get back bashin
 
gslst2,

I did get it sorted out. I replaced and cleaned the OWB inside the gear case. I used simple grease to break up all that extra grease and and then put 1 or 2 drops of household 3-in-1 oil in the middle instead. This worked fine. I think it was oldLS on here that suggested that to me.

I haven't been bashing in about 6 months as I have been short on cash to replace parts. Let me know if that helps you out at all.
