How to rebuild a velvet drive 10-17-004 1:1

HERE IS A FEW PHOTOS I TOOK WHILE REBUILDING MY VELVET DRIVE MARINE TRANSMISSION ..

ROOT OF CAUSE FOR REBUILD WAS THAT I RAN IN REVERSE INTO SAND BANK DURING LAKE TRIALS AFTER I BROUGHT THE SUNSPORT HOME , FORWARD WAS
STILL IN GOOD WORKING ORDER SO I JUST WENT ABOUT MY WAY ... THIS IS WHAT I FOUND AND HOW I WENT ABOUT TO REBUILD MY TRANSMISSION , :NOTE:
I AM NOT A PROFESSIONAL AND THIS WAS MY FIRST TRANS REBUILD OF ANYKIND ! EXCEPT REGULAR TRANFER CASE AND REAR ENDS ...

FIRST DRAIN THE 2 QTS AND REMOVE THE STRINGER MOUNTS ....http://i1189.photobucket.com/albums/...6/a035f519.jpghttp://i1189.photobucket.com/albums/...6/b7ca9b63.jpghttp://i1189.photobucket.com/albums/...6/b31237c1.jpghttp://i1189.photobucket.com/albums/...6/6f9d558a.jpg

NEXT MARK THE FRONT PUMP HOUSING I USED A PUNCH TO MAKE TO CORRESPONDING DOTS TO LINE BACK UP WHEN I RE-ASSEMBLE .. VERY IMPORTANT YOU DO THIS , THE PUMP CAN BE MOUNTED FOR LEFT ROTATION AND RIGHT ROTATION SO ITS IS CRUCIAL YOU MARK IT

REMOVE PUMP HOUSING WITH SMALL PICK OR (TWEAKY FLATHEAD) , CLEAN SHAFT FROM SEAL PITTING AND DEBRIS FOR PUMP GEAR TO BE REMOVED ....

REMOVE CAP BOLTS USING A 12POINT 3/8 SOCKET http://i1189.photobucket.com/albums/...6/61d43ca3.jpg

TAP LIGHTLY TO SPLIT PUMP CASE FROM TRANS HOUSING, USE GRAVITY TO HELP POP IT LOOSE WITH OUT SCARING CASING http://i1189.photobucket.com/albums/...6/e2db7766.jpghttp://i1189.photobucket.com/albums/...6/962aa3e2.jpghttp://i1189.photobucket.com/albums/...6/88f59baf.jpg

SET CASE TO THE SIDE .... http://i1189.photobucket.com/albums/...6/5fb2cd13.jpg


AND THIS IS WHAT HAPPENS WHEN YOU DON'T PAY ATTENTION TO YOUR SURROUNDINGS http://i1189.photobucket.com/albums/...6/1e5a7d0a.jpg

PULL THE CLUTCH DISC AND STEEL PLATES AND SET THEM ON A STAGING AREA IN THE SAME ORDER AS THEY WERE REMOVED http://i1189.photobucket.com/albums/...6/a30aa87c.jpg

Thanks for these pics. Looking forward to seeing the rest.

ONCE YOU REMOVE THE PLATES YOU CAN PULL THE FORWARD SPLINE GEAR AND CLUTCH PACK... THERE WILL BE 2 SNAP RINGS THAT NEED TO BE REMOVED TO PRESS SHAFT OUT AND SEPARATE THE CLUTCH PUMP ASSEMBLY http://i1189.photobucket.com/albums/...6/5eb237aa.jpghttp://i1189.photobucket.com/albums/...6/d9177809.jpg


SHAFT IS PRESSED THROUGH THE REAR AND THE BEARING WILL PULL OUT WITH YOUR FINGER http://i1189.photobucket.com/albums/...6/938fb6b5.jpghttp://i1189.photobucket.com/albums/...6/165aecfe.jpg

http://i1189.photobucket.com/albums/...6/74fd7d9f.jpghttp://i1189.photobucket.com/albums/...6/b97870a6.jpghttp://i1189.photobucket.com/albums/...6/59fb457d.jpghttp://i1189.photobucket.com/albums/...6/f5f28fe2.jpg

BE SURE TO STAGE PARTS IN THE ORDER THEY ARE REMOVED AND LABEL IF YOU ARE UNCERTAIN

PULL THE PRESSURE PLATE ASSEMBLY AND SET ASIDE http://i1189.photobucket.com/albums/...6/a1ef6f09.jpg

REMOVE SNAPP RING FROM CLUTCH PACK http://i1189.photobucket.com/albums/...6/7c5b1cb2.jpg

SET CLUTCH PLATE IN ORDER AS THEY ARE REMOVED http://i1189.photobucket.com/albums/...6/4678d464.jpghttp://i1189.photobucket.com/albums/...6/1d017544.jpg

http://i1189.photobucket.com/albums/...6/db66347e.jpg

NOW GET TO A PARTS WASHER OR MAKE A TUB WASHER TO CLEAN ALL PARTS AND LAY NEW CLUTCH DISC IN A NEW TRANSMISSION DEX III OIL BATH TO
PRESOAK AND LUBE DISC AND PLATES FOR RE-INSTALLATION , AIR DRY ALL SOLVENT FROM PARTS AND START WITH A CLEAN AREA TO INSTALL FRESHLY
SOAKED DISC INTO SPLINE CASE (FORGOT TO SNAP A PIC OF THE NEW DISC GOING IN ) ALSO THERE ARE 2 SEALING RINGS THAT COME IN THE KIT THAT WILL NEED TO BE REMOVED FROM SHAFT AND REPLACED WITH NEW .

***CHECK THE GAP FROM THE (SNAP RING TO THE STEEL PLATE) AND MAKE SURE THE TOLERANCE IN IN SPEC OF 0.0018'' - 0.0053'' ***

yeah man i have been so swamped with side work and rain that the floor with be screwed on and glassed and painted this week , and then its going to the paint shop for a new look while i recover the interior ..

Wow!!! That's a great walk through. Good job on stopping to take pics step by step. Did you have rebuild instructions for the transmission? Hats off to you if you did all that with no guide. I consider my self fairly mechanically inclined but to takle something like that I would have to have some intructions. If I didn't, I would have left over parts when I put it back together, haha.

yes i had the rebuild manual , just never could find a rebuild on the internet ... so there ya go

Hey, Lively....just sent you a PM. I live in Ft.Worth, too, and have the same exact Velvet Drive that MAY need rebuilding. If so, I need to git 'er dun before end of this month! Hope we can keep in touch.

Nice thread, it's always really helpful to have stuff like this to refer to when you have to tackle rebuilds.

These velvets are very simple drivelines , just pay attention to your snap rings and the friction plate gaps , very important to set
The gap per manual or it will slip and you will have to pull apart and rebuild again .. I hope this helps out ... and good luck. !!

Nice post brother! This will be so helpful to anyone who has to do a rebuild. I wish this was up a couple of months ago when I did mine. The reverse plate was sheered in half also. Thanx again for the good pics and post!

Lively, can't thank you enough for the helpful post, pics, AND the personal help you gave on the phone a week or so ago. After following your instructions, I removed my noisy tranny and replaced the dampener plate. Made all the difference in the world, and not too soon! My family had a week of trouble-free fun on the lake last week. When (and if) my tranny needs an overhaul I will likely give you a call. Thanks for everything!

Not a problem brother . Pay it forward

Dear lively, I am getting ready to rebuild my velvet drive - and found your pictures on the supraboats website - however starting on post #4, the pictures are "Not Found". Do you know why not? From what I saw (the initial pictures & comments) -it appears like it couldbe very helpful! Thanks for any help!
Charles

Hello.
Perfect post, but I can not see any picture as Charles2014, please if it possible - improve this

Hello, have you rebuil your velvet drive?
