New PK owner. I need to fabricate the belt tensioner for my 1968 PK with the center mounted starter/generator. Can anyone post a picture of one, maybe with some basic dimensions? When I got the tractor last summer it had a fabri-cobbled one on it. Thanks.

Welcome to GTT. PKs are great tractors. Check in our Manuals Section. Someone that can help you will be along. BTW we like pics to help understand questions. You can also check with our sponsors for a used one. Good Luck, Rick

Thanks, Rick. Couldn't find anything in the manuals. Does anyone know which model years had the centered mounted starter/generator? That could help me find a parts list, maybe.

I had to make my own starter generator mount and adjuster when I built my PK. I somewhat copied the original set up and it works great. I made the tensioner out of a long bolt. I just cut the head off, ground a flat where the starter generator attaches, and drilled a hole in the flat. The lock washer does not need to be on the tensioner as you see on mine. I removed the lock washer and just used two nuts.

I have one I could take a picture and give you the sizes but the one classic made is so much better ,

[Glarnold]

Thank you all. The one Classic made looks very nice and do-able. Maybe a little worried about placing all that load on the clutch housing. Perhaps a plate to spread the load. Thanks again for everyone's help

[classic]

You're welcome. The housing will handle the pressure of the adjuster with no problems. A plate wouldn't be a bad idea to spread the load, though. Here is a drawing of the adjuster from some Economy paperwork that I have. Only two square nuts were used on the adjuster in this drawing.

OK, I guess the PK designers weren't worried about the load issue. So, I'm off to the shop. Thank you, Classic. And thanks everyone!

You're welcome. I've been using my PK quite a bit for the past year now with no problems, so have at it. I used a 5/8" diameter bolt and nuts to make my adjuster.

 If you were to tighten that adjuster tight enough to damage the casting you would most certainly destroy the SG bearings in short order.  Don
