Scout 800 Throwout Bearing

I am in the process of repairing my clutch/transmission/throwout bearing and want to make sure that I install the correct throwout bearing. I have read many posts about greaseable and non-greaseable bearings and am confused. Hopefully with some pictures I can clear up the topic. I have an inkling that what I took off is not correct.
First off this is for a Scout 800 with a 152, t18 and Dana 20. Attached are some pictures of the removed throwout assembly. It is obvious that it is a non-greaseable unit, there is no grease zerk. However, looking at the bearing, it appears that there is an opening to the innards that would be positioned on the “inside” of the assembly. I have read that having a greaseable bearing on a non-greaseable sleeve (collar) is a no-no. Makes sense, because there is no way to grease it.
I have also read that it is possible to make the sleeve (collar) a greaseable unit by drilling a passageway and installing a zerk. A picture or better description of this process on a sleeve like this would be very helpful. I think most of the posts are about Scout II/v8 throwouts, which are apparently a very different setup. I have also read that you could drill a small hole in the side of the bearing in order to get some grease in there. What bearing do I need to work with this collar?
Also, on my collar there are two holes drilled and a broken off roll pin. I found a photo of the same sleeve with the roll pin present. Does anybody know what the function of this roll pin is?
Thanks in advance.
Ps: I am in need of a new front bearing retainer for the t18. The "tube" broke off which is what perhaps what caused my clutch problems. If anybody has a retainer for a 15/16 10 spline shaft please pm

Thought this had been answered but I guess not.
The pin is necessary to keep the collar from rotating and wearing the fork tabs off...

As far as I know there is no geasable collar for the 800/80 nor is the bearing itself greasable. They are simply replaced.

Be sure to grease the collar and retainer liberally before installing.

If you pull the clutch cover you can lubricate the collar/retainer interface with a spray grease and nozzle. This would only be as a maintenance item.
 
I believe have figured a way to have a greasable throwout bearing on an 800 with a pancake bellhousing.
I ordered a n-1610 bearing which is a greasable bearing with an angled zerk. The zerk would contact either the fork or the clutch body depending on how it was aligned. A straight zerk was also too long to clear the clutch.
After lubing the bearing I removed the zerk and capped the threaded hole with a short allen head cap screw and a little blue locktite.
The manual calls for lubing the bearing every 10k miles. I should be able to remove the cap screw and insert a straight zerk to lube the bearing.

Happy to hear you are still active.

I have been working with another member, ohio Jeff, to see if a t 18 tranny he has can be made to fit in my oddball 1966 Scout 800.

You might know the answer as to whether or not, I can make that happen.

My set up is a 152ci with a t90 tranny 2whl drive Dana 27 3.73 rear pumpkin that I want to upgrade to a t 18.

Jeff's appears to be a true t 18 (wide ratio) not a t 18a close ratio. It is a 2whl drive, (pto opening on right side covered by plate) and has the early shift pattern (reverse over and up), but its bolt tag has t 18, not t 18a. He is checking to see what the borg warner casting alphameric is on drivers (left) side of the tranny housing, but am guessing it will be t 18, unlike t 18 a on a recent ebay tranny housing.

Am guessing your t 18 trannys are, actually, t 18as (close ratio, as has been touted by references to be the only ratio installed in early scouts. However, the proof is in the pudding, so you will know, for sure. The 4.88 ratios in your pumpkins lean in that direction.

Jeff's tranny has the larger diameter input shaft, not like ours. Know you were looking for a small diameter front shaft retainer/tube. Did you ever find the parts?

Not sure if parts exist or were ever made to allow mating Jeff's tranny to my 152 ci engine.

If not, then I am going to have to keep on looking and for small diameter front shaft t18s as are in yours.

Your trannys are close to what I am looking for except they are four wheel drive. Probably, are more common than 2 wheel drive configurations, so maybe I am going to have to consider, finding a Scout 800 like yours and convert my drive train to four wheel drive.

Know that you will, probably, want to keep stripe as a spare for black dog. Have you run across any other ones like yours at meets, etc.?

Jeff is checking on his tranny casting #, gear set and I have ordered the parts manuals, to have with my truck service manual in order to try to sort this all out, lacking actual trannys like yours.

Any thoughts would be greatly appreciated.

Thanks in advance.
