May I enlist the assistnce of the more seasoned/veteran members herein. especially those that are rear mech. experts?

I'm in the process of rebuilding/reconditioning a spare replacement Shimano Deore XT RD M739 8 speed rear derailluer. I made this one from the parts of two used ones that I purchased on eBay. The composite result has turned out fairly good.

I am looking for a couple of things yet. Here is what I need:
Technical diagram or link to it. A .pdf Shimano tech docs exploded diagram for the M739 rear derailluer, or a link to same. A thread in this site from about 2 years ago contained a link to a M750 unit. However I cannot find a link to the older M739 unit. Does anyone have a copy of the M739 .pdf or know of a site that has it? I am unable to find it on the Shimano tech docs site (do they have a different site for older gear?).

Jockey/pulley wheel set, or links to sites where I can buy same. I need a NOS pulley set, preferably OEM parts, but aftermarket will do. This is an 11 tooth pulley wheel set, with the upper wheel containing the ceramic bearing.

Lastly, several directly related questions for the rert mech experts. In buying a 11 tooth pulley set from Shimano Spares (Y56398100) earlier this year, I discovered that these wheels are wider than the originals. Are they compatible/will they work? I'd need to find a pair of longer bolts - but can the wider wheel work and perform properly relative to shifting operation/action/smoothness?

Where can I find a set of the correct width? I'm not interested in the gold anodized titanium bling stuff, just a replacement set of jockey/pulley wheels of the correct type, tooth count, and width. I'm a bit puzzled by the apparent lack of this stuff, as they are a "wear & tear" item like the chain, cassette, chain rings, and bottom bracket. All of this stuff is readly available. Am I missing something, or has it all gone to eBay?

Anyhelp, tips, suggestions, and recommendations are appreciated!

The Shimano part numbers for the pulley set are:
Shimano 53H 9808 and 53Y 9807. A Google search doen't find anything available.

Anybody know if they been replaced by a newer part number?
 
Look for replacement types or grab them from another mech. There is nothing 'special' about the pullies other than the M739 being of a specific quality.
Tacx make various grades of compatible one.

Look for 10 tooth 8 speed version, not the 11 tooth 9 speed version.
 
Hi all - can I get this thread going again as I have the same issue.

I have an XT M739 rear mech marked 8 sis, and am running it with an 8 speed setup. I found what I thought were the correct jockey wheels (10 teeth for 8 speed) but they are too wide to fit in the cage.

Can anyone point me to a link where I can buy an appropriate set? Happy with non Shimano, they just need to fit.

Many thanks. :)
