| Sometimes the main clutch handle, on my HD-5 crawler, acts like something broke or came loose. I can move it back and forth with no resistance. Eventually, it will "straighten up and fly right" and works like it's supposed to. Any ideas? Thanks. |

Open inspection cover on bell housing and observe the workings of the over center clutch . Had similar problem when one of the arms came loose from throw out bearing , arms are heal in by pins and have cotter pin to hold in - one came loose . Also another thing to be aware of is the throw out bearing rides on a brass sleeve and when machine is idling transmission should be in neutral with master clutch engaged to prevent wear to this brass . there are grease zerks in the piece which need greasing also . ------------- Faith isn't a jump in the dark.

| I forgot to ask, how many "pumps" of the grease gun should these zerks be given and how often? Thanks, again. Bob R |

General rule of thumb is to grease till you see a little come out the other side. Or listen and feel the pump, as the cavity fills, you will feel the hose tense up, then hear a small poch (phonetic spelling), as the grease seal (if it has one) unloads. On small diameter shafts, about 4-5 pumps, more on larger shafts, or if it haxn't been greased in years...

the clutch should SNAP over-center in both engage and disengage movement . A definite noise should be heard when moving lever as well as a resistance to movement felt in lever travel. The clutch pressure plate is adjustable - by loosening a hold down bolt and moving slotted ring . amount of grease would depend on how worn parts are or how often machine is used. Sometimes a little is better than a lot . ------------- Faith isn't a jump in the dark. It is a walk in the light. Faith is not guessing; it is knowing something.
