154 throttle

Sat May 10, 2008 9:48 pm

On my 154 the throttle will not remain where I set it. Anything over 1/4 to 1/2 throttle
and it will move back on it's own when I let go of the lever.
What is the fix for this, I saw posted somewhere that this was a commone problem.

If you look through the slit the lever sticks up through, you'll see a nut on the side of the lever pivot. Just snug that nut a little, till you get the tension you need.

I have a owner's manual for a 154 Lo-boy if you want it. $10 shipped to you.

Using a 1/4" Dr ratchet with a 7/16" shallow socket and a 7/16" open end wrench you can tighten it. You use the socket wrench from the bottom and the wrench from the top slot.

just in case its like my 69 154 it dosent have a bolt and nut thru the lever , the local dealer said to take it out and gently tap the rivit on a anvil with a ball pin hammer lightly to snug it up, but since i truck 6 days a week i havent done that trick yet and just used a small bungie cord to hold the lever up :( . but lst year i did get the main drive line repaired from engine to tranny, and that was a chore for me.. the engine collet to shaft was wallowed out at the bolt and nut part and i took all that little noise i could stand. so ove time "got er done"

When my throttle lever became loose i put my folded up leather work glove to work in the slot. I pushed up the throttle and stuffed the glove in the slot to make it hold until i tightened up the level. Sometimes we need to do a "manual data input" to get the job done.

i bought a brand new throttle cable assembely and installed it to find out it was too loose also , the new ones have a phillips head on one side instead of hex , so in that case you will need a right angle screw driver .
