Reported cause
Mid year 2000 some engines began using the single row bearing, 2000 model year cars can be either single or dual row, there is no rhyme or reason to these and directives that state what the engine is equipped with have proven to be less than accurate.
Leading evidence: 'less than accurate' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'less than accurate' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace late 2005 bearing if they were' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

So from what I understand from your PDF you are now able to replace the late 2005 bearing if they were to fail?.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Our buyers guide (available free on http://www.hartech.org/buyers.html section 5 now contains more information and photos about, equipment necessary to re-machine Lokasil (pages 16-1, new oil spray jets directed at the bore scoring area (page 54), the problems with iron (or steel) liners (from page 57), some reasons for smoking on initial start-up (page 64) and our new IMS shafts (currently in manufacture) that are fitted with the latest large IMS bearing (generally regarded as permanently solving the weakness) that will be available for all models including the older Roller chain engines (pages 69 to 70).

Yep thats got it.
Thanks Richard.
Wondered why Baz didn't put a direct link to the PDF in the first place!.
"Leave the Computer alone and get back to the Spanners Baz".
So very good news for anyone that got a rebuilt engine from OPC with blue marker then right?
As this bearing was not replaceable till now and although like you say failures are less likely at least they will be fixable.
???
Baz,
Below is Jake Raby's recent post from over at renntech.
So from what I understand from your PDF you are now able to replace the late 2005 bearing if they were to fail?.
By completely replacing the shaft?.
97-early 2000= Factory Dual Row
Mid year 2000 some engines began using the single row bearing, 2000 model year cars can be either single or dual row, there is no rhyme or reason to these and directives that state what the engine is equipped with have proven to be less than accurate. Until a visual inspection of the flange is carried out there is no way to determine which bearing is installed.
Post 2001-early 2005= Factory single row with the standard outside diameter. These bearings were not an upgrade at all and they have the highest instances of failure with the most radical damage since the bearing is 1/2 as large as the earlier dual row bearing.
2005 Model year- Can be either the standard single row bearing or the later, larger diameter "upgraded" bearing. Like model year 2000 these cars require a visual inspection to determine which bearing is installed.
Late 2005- end of M97 production= The "upgraded" bearing that is generally referenced. These are the bearings that can't be extracted.
In reality there was only a single upgrade, the larger bearing applied in 2006. These also fail and I have one at the shop now that beings to a client who has experienced two failures in the same car.
The 97-99 dual row bearings are the most robust. All generations of the bearing fail, 01-early 05 are
by far the worst.
This is a source reference. Confirm exact model applicability in the original material.
