TRYING to locate the freezings plugs on my B7100 hst D750 engine.
No white OR blue smoke from exhaust. No exhaust from radiator either and not water in the oil. Thats what leads me to believe it to be a freeze plug.
Problem I have a small water leak coming from the rear area of the engine. I'm thinking perhaps a freeze plug issue. If that's it can it be replace w/o pulling the engine?
Does anyone have a diagram of this, I DO HAVE a shop manual but very blurry pictures.
AND is there other freeze plugs and should I replace them at the same time for precaution?

Yes there is a freeze plug in the rear of the block, and the only way to get to it is to split the tractor.

I bought an L2050 a few years ago that had that problem, except worse!! Here's a picture of where the plug is, above the clutch. The clutch had set in the leading water for a long time. The dowel with grease is how I removed the pilot bushing, and the freeze plug laying on it was the culprit. It's a lot of work to get to a $1 part.
