Raider12 belt tensioner

[Floyd Pink 44]

I hate to beat a dead horse but I have tried everything on a Raider12, 1968 model.

  The idler pulley does not appear to move far enough with the clutch /brake pedal pushed down to loosen the belt. It was working fine until it wasn't. The tabs are bent, the cover is on. The tab that is on the cover y'all always talk about was never on the cover. 

 Is it possible that the drive belt is worn enough that the tabs can't grab the belt? 

   It all started when I replaced the brake lining 

I've adjusted everything

You've covered most of the things that would correct the problem. The things you didn't specify are if you have the OEM belt, or if the belt you have is fabric covered or not. An OEM belt isn't required, but at least should be both the correct length, and fabric covered to allow slippage when tension is released. 

 

The only other thing I can think of to ask is if the idler pulley is original or at least the correct size. 

 

This comment may bring out some smirks, but I rarely have OEM belts to use on my tractors. What I do make sure of though, is that the belt is the correct size and type. Sometimes that can be difficult when WH used some oddball sizes on OEM belts.

On the left side of the tractor, the rod for the clutch. their it's attachted to a pivot point. 

Often that pin inside breaks. 

You can see here is some metalwire in place.( But that is not a correct solution. as it has to be a tight fit)

See If you have some slop in there.

Sounds like the brake is applied before the clutch is fully released.

Back the brake off to get the clutch working and then do the brake.

Adjustment procedure is in the operator manual.

Like Garry @gwest_ca said, if the brake adjustment is too tight you won't be able to push the clutch in far enough. On page 6 of the owner manual it covers brake adjustment as well as belt guard adjustment. Another thing to look at is the right side running board, if it is pushed in too far it can interfere with the clutch. Hope this helps.

Tried and tried to no avail.

@Floyd Pink  looking at the nail in the lever and related rust , typically tells me the problem is that, the intended  operation , is being used up before moving. gone over every one of my sloppy linkages , firmed up with washers and lubricant . most important part of movement is the starting movement , correct dowel pin to secure that lever , would help its swing arc. the pull lever is also probably sloppy . seen this set up in many dysfunctional , horses, pete

Do you have some unwanted movement in the linkage I told you?

Idler pulley is original. The belt is from the Mid-70s. Gates B belt. I probably sold it to him as I worked in the autoparts store when I was high school. I noticed a few minutes ago that the belt is starting to come apart. It's so worn out its riding just below pulley groove. I am going to find the part number for the belt a replace it.

B belts do not work well in this application. You need a 5L belt

Not my picture. 🤣 No rusty nail for me.
