I'm wondering if there are any B26 owners out there who might be able to help me out by taking some measurements from their BT820 backhoe.
First an explanation: I noticed that the BH77 backhoe that goes on the B3200, B3300SU, L3200 and L3800 - looked very similar to the BT820 backhoe that goes on the B26 tractor - and it's approximate measurements are very close to the same.
So I got to wondering if the quick attach bucket system that is on the BT820 - could be adapted to the BH77 backhoe.
Then I started doing some digging and found out that:
- the pin on buckets available for the BT820 are not the same part number as the same size buckets for the BH77. So for some reason (as yet unexplained) there is something different about the buckets, but -
I also found out that there are at least two parts that are shared between the BT820 and the BH77.
These are the "link bucket" - which is part# 7K523-41210 - or "D" on this picture I posted:

The other part that is shared between the BT820 and the BH77 is are the two pieces that are on either side of the "link bucket" - these are called the "guide link" and they are different side to side.
the two part numbers are:
7K523-41110
7K523-41150
This is the part I called the pivot arm in this picture:

The last pieces of information I need to make an educated guess that the piece from a BT820 that lets you use quick attach buckets - could be adapted onto a BH77 - are some measurements.
I tried to separate them out to make it easier to follow - and put a big letter on each for reference. The pics are taken were borrowed from pics posted by a fellow member here of his B26. They were the best ones I could find to illustrate the dimensions I want to compare.
Picture A: distance between the center points of the two pins on the actual quick attach - on the BH77 bucket it would be the two pins that attach the bucket to the dipperstick

Picture B: distance between the upper mounting point of the thumb cylinder - or extension bar in the case of the BH77 - and the bucket pivot point on the dipperstick

Picture D & E: I don't really need the "D" distance - I've already confirmed that the part is the same on the BH77 and the BT820 - but I do need the bucket pivot point and the extension arm pin on the dipperstick ( E ).

Picture F: I couldn't find anything that was very clear - but basically what I need is the WIDTH of each of the pin points or maybe a better way to put it is the width of each of the components where they fit onto the dipperstick. If the dipperstick on the BH26 is for some reason wider than the dipperstick on the BH77 - then nothing will fit.

I'd take the chance and just go out and buy the quick coupler part - which is PN# 7K523-83110 - and is $185.00 according to the Messicks online parts catalog - but I would rather make an educated guess - rather than a wild stab in the dark - before trying it out to see if it will fit properly.
Seeing if the measurements match up between the BT820 and the BH77 would very helpful towards that end.
