Hiyas, does anyone know what service letters or bulletins Kubota published in the late 70s - early 80s, for augmenting or correcting their WSM, and what was/were the official name/s? I noticed in a WSM for the M4500 that there are a number of hand-written edits to dimensions which must have come from factory edicts and I was curious to know what title or name those documents had.
Thanks in advance.

They are "PSB"s and are used to update, announce, inform and correct service information.

Thank you Whitetiger
I'm guessing that PSB = product service bulletin? Is that correct?
That is correct. Here are a couple of examples of the old PSB's back when they were just SB's.

OMG! Thanks for those, I'll have a look at the studs, and I haven't pulled the engine down but may need to at some stage.
Please tell me... what do I have to do to get a full set for the M4500 and S2600?

You would have to get a dealer to do searches and copy the PSB's for you

Thank you, I'll try that.
No luck, 2 dealers I have tried say they can't retrieve anything that old, one of them spent time rummaging through stuff for about 10 minutes while I waited and couldn't find anything. Not surprising I suppose.
