Ok cool. Good news for once haha. yeah they don’t look to bad but I think I’m just going to replace them all since I’m in here.Good news! You've got the better wide stator support and wide bushing in the drum. How do the pump rotors look?
Those are teflon seals on the snout, but they are flush-cut. The newer ones are "Scarf-cut" which means they are
cut at an angle and overlap each other. Less leakage. How do the bronze bushings look?
no worries. I see that in the service manual. Will give it a crack and see how we goThe wide support needs the wide bushing front drum. Properly installed the teflon seals are great. Look at the pump rotors then measure the tip clearance on each. The stock OEM range is excellent.
yeah me to. I’ve tried to contact CRT so I will wait for his response.In my years building 727's, I think I've needed to replace one set of pump rotors that had a lot of damage, nicks/gouges. Maybe a couple of pump housings that had wear that concerned me. Even the 727's when I broke the convertor didn't really affect the pump. The valve body may be another issue though. I'd be looking for a new valve body to match your application.
sweet i will check his video out today. i believe it does look like that but i will double checkWhat type of spring do you have in it? There are two types. One is the later spring and it's stiffer.
I'll post some pic's of both.View attachment 1292734
This is the preferred stiffer bellvue spring. Yes, there is a little play in the retainer because of factory tolerances. You can tighten it up by replacing the piston with a Billet unit from John Cope. There are two different heights to work with. I believe they are 0.850 and 0.875. Go to youtube and watch John Cope's video on this!
Spoke to John this morning. Pretty keen on his stuff now. One thing I did notice on the input shaft is where the 20mm wide bushing in the drum sits, it appears the shaft is only 15mm.it’s wider but the bushing has only been wearing on 15mm due to the step. Is that a mismatch? New shaft?That is a very interesting, informative vid. In all my builds I've had the early style spring with up to '78 727' cores. I keep my rear clutch packs together and don't mix them.
