Guibo Confusion

Long time since posting here as the '02 has been in my son's hands and performing brilliantly and I have been working on an '73 E3 restoration - but the subject of this post it is the '02's flexible coupling and it is confusing me.

 

First, it started because I noticed a few things amiss with the car - drives like a train but had a squeak when turning the steering wheel and a bit of clunking under my seat when accelerating hard in lower speeds.

 

So up on the hoist it went two weeks back and centre bearing was on its last legs, auto transmission mount shot, one of the spindle ends of the central steering arm was toast and universals needed replacing on the driveshaft.

 

So all good, thinking  I will order some parts from Walloth & Nesch in Germany for these works as I had an order for the E3 to go in anyway. Now I whack the verniers on the bolts on the guibo (insitu) and they fit 12mm holes. I note that the coupling is the donut type and a 6 bolt set up.

 

Now I am home combing thru the order online and note from the catalogue that the coupling for the auto is either a 10mm hole arrangement (26 11 1 100 837) or a 12mm hole arrangement (26 11 1 109 603) - however this is listed as also for the E3. So I order 2 of them (one for the E3 as a spare only) BUT note they are NOT the donut kind. All the literature I have read suggests I shouldn't have the donut in there but the THINNER flat guibo.

 

Now fortunately, the '02's guibo is in excellent condition and I bought the new one assuming it would still fit (obviously physics wasn't my strong point!) and I was just going to change it out as well, for a complete refresh on the driveshaft.  So even though the one received is the thinner, flat variety there are no issues getting the car back one the road as I will just use the current one.

 

Normally I am not an idiot, but this time I think I passed the "test" to graduate as one.

 

I will recycle it on eBay for someone who needs this type of coupling, but the mystery remains, what part number do I have on my car because it simply doesn't match anything on RealOEM, W&N's catalogue, etc. that is supposed to suit - mine is an Aussie car, Euro-spec '72 Auto - pretty common.

 

This is what I have that works to date.

I would be grateful if anyone can explain where I went off the rails.

 

All the best

P.S. Everything else went on smooth as! Tailshaft will go on mid-week once the specialists have replaced the universals and balanced it all.

The "Blue" parts book lists Guibo 26 11 1 107 832 for the 2002 Auto (still available).

It is a 6-bolt 12mm Guibo. This looks like the one you need.

It's also found on a variety of BMW cars, E3 included.

Also listed is 26 11 1 203 783 (superceeded by 26 11 1 109 603) which is the flat type also used on 2002 Auto et al.

Blue book is confusing (to me anyway), but if your VIN is 2520763 or below/before you need 26 11 1 107 832.

If your VIN is 2520873 and above/later, you should need the flat style Guibo.

If your VIN is in between.....lottery!

Thanks Les

 

Mine might be the exception to the rule then - VIN is 2521453 - which should be the flat variety but evidence (as in what is fitted and working currently) says the donut (...832) is the option - the mystery grows ...  :huh:

 

Looking at the W&N catalogue and price list, I ignored the ...832 part when ordering as it said it was for manual gear box only, so that is worth letting them know so it can be corrected. 

 

As I drafted this post, I did a quick check of Realoem which can be useful as well and when I fed into the part search facility the ....832 number, it took me to a drawing which only listed the flat faced guibo ...603 part number - that in itself makes no sense. 

 

I think now that you have explained the right part number, I know what to order from someone later should the guibo give up the ghost.

 

Thanks

 

Richard

The part no 26 11 1 107 832 should have taken you to page 26/7 (after being directed to the page that shows you that Guibo is also used on E114, E12, E23, E24, E3 and E9 first)

 

The picture shows Guibos 10, 13 & 15 (10 is only for manual cars).

 

According to RealOem, Guibo 13 is for both manual & auto cars......the BMW "Blue" parts book only shows it for autos.

and you can download the Famous/Infamous "blue" book. Pages 512-513 show the Guibo.

Thanks Les - I found following your path the right part number and part ...832. What's funny is the same part number indicates it is right for the 3.0s Auto but when you select that option the part on that page 26/2 is ...603 - the 2002 you have helped me figure though the numbering for the 6 cylinder seems still askew. 

 

Not an issue as such as the '02 mystery is resolved - thanks.

 

Tell me , why is the blue book famous/infamous? Thanks for the link also.

 

Regards

Richard,

I refer to the Blue Parts Books as infamous sometimes, as they can be as confusing as RealOem.

Some parts that you would expect to find in one section are hidden away in a section you would never think of.

I think the designers of the book had a sense of humour.

Overall they are excellent are very useful if you have to order parts from the Dealer as they have no clue.
