iancshafer Posted April 16, 2016 Report Share Posted April 16, 2016 I did a swap from the four speed, to an FS5W71B. I kept the original clutch and pressure plate, bought a new throw out bearing and clutch fork for the new FS 5W71B. It had an L engine housing already and bolted straight on. I can reverse and get into first gear, but when I going to higher gears at higher rpm's the clutch slips. I have tried to adjust the clutch adjustment bolt thinking I needed more pressure on the clutch to the pressure plate, maybe I haven't found the sweet spot? Any advice appreciated.

Lockleaf Posted April 16, 2016 Report Share Posted April 16, 2016 Which release bearing collar did you use? The one from your 4 speed or the one from your new 5 speed? 1 Quote Link to comment
iancshafer Posted April 17, 2016 Author Report Share Posted April 17, 2016 I bought a new throw out bearing for the 5 speed. I may have got this wrong, but thought the clutch pressure plate is mates to the engine and the throw out bearing is specific to the trans. Quote Link to comment
john510 Posted April 17, 2016 Report Share Posted April 17, 2016 Was the new throwout bearing already attached to a sleeve ? I think the the throwout and sleeve are mated to the clutch not the trans. Quote Link to comment
Lockleaf Posted April 17, 2016 Report Share Posted April 17, 2016 I mean the thing that the bearing sits pin and the fork clips to. Is that from the 4 speed or the 5 speed? This part. 1 Quote Link to comment
iancshafer Posted April 17, 2016 Author Report Share Posted April 17, 2016 It was the 5 speed Quote Link to comment
bananahamuck Posted April 17, 2016 Report Share Posted April 17, 2016 You should have used the same collar as the 4speed since not all clutch plates are the same height/depth,,, or measured to see if the collars were the same / different. Is there any adjustment on the slave cylinder rod ? BUT is it slipping when you are in 5th and loading it down,, such as going up a grade?? It might just be you need a new clutch and the 4speed didn't show it as much as 5speed will.. I would pull tranny out and compare collars first and go from there. 2 Quote Link to comment

If you have a new FS5W71B clutch arm, it does not have the hole in it for the adjustable slave push rod. If you are able to adjust it then something here is not adding up. You need an FS5W71B slave pushrod or the 4 speed clutch arm with the adjustable rod. Mixing these two may be the problem. Your clutch slave pushrod may be too long. TWO Having said this. Your clutch arm should have a small amount of play or looseness between it and the pushrod. It should not be tight. Figure this out before going to THREETake 5 speed transmission out.Take new release bearing off the 5 speed collar. (tag the collar as not L16 and put in sock drawer)Put new release bearing on your old 4 speed collar.Install new bearing /old collar on 5 speed clutch armInstall transmission.Enjoy driving around. You 4 speed collar is matched to your clutch. It's a 200mm. The new 5 speed collar could be matched to who knows what??? clutch. Keep your 4 speed collar with your clutch. They were made for each other. Release bearings are all the same part. 1 Quote Link to comment
datzenmike Posted April 17, 2016 Report Share Posted April 17, 2016 I mean the thing that the bearing sits pin and the fork clips to. Is that from the 4 speed or the 5 speed? This part. Lockleaf I know this is just a visual example for showing what you are talking about. However the collars are NOT, in any corner of our 11 dimension universe, related to the transmission. The collar is intimately related / married / wedded / matched to the clutch pressure plate. So anyone looking at this ignore the transmission labels and just know there are different sizes. If you had a Type B 4 speed and put a later Type B 5 speed in, according to this chart you would have to swap the collar, and you do not. You would keep the original collar and just change the transmission. 1 Quote Link to comment
iancshafer Posted April 17, 2016 Author Report Share Posted April 17, 2016 Many thanks! First transmission swap, appreciate the help. Will give it a try next weekend. Quote Link to comment

Question for you Mike, I was a bit baffled by this and it turned out one of my team members modified the clutch fork by drilling a hole in it to accommodate the slave push rod. Do you foresee any issues with this? Quote Link to comment
banzai510(hainz) Posted April 19, 2016 Report Share Posted April 19, 2016 just use the old stuff. meaning the t/o collor I have a 5 speed but used the orginal fork. but if its drilled out then should be the same adjustment 1 Quote Link to comment
iancshafer Posted April 19, 2016 Author Report Share Posted April 19, 2016 That's assuming I have the old part, sadly we tossed the old t/o bearing assembly. Need to start digging around the shop. Lesson learned. Quote Link to comment
datzenmike Posted April 20, 2016 Report Share Posted April 20, 2016 I see no problem with this. There has to be a slight clearance between the arm and the push rod adjuster. A small wiggle room. Never throw stuff away. Label it and put somewhere. 1 Quote Link to comment
iancshafer Posted April 23, 2016 Author Report Share Posted April 23, 2016 Thanks gents, worked like a charm! Clutch is nice a tight now, shifts like a dream. 2 Quote Link to comment
banzai510(hainz) Posted April 23, 2016 Report Share Posted April 23, 2016 well what was the fix 1 Quote Link to comment
iancshafer Posted April 23, 2016 Author Report Share Posted April 23, 2016 Put in the 510 throw out bearing vs the 280zx throw out bearing. I mistakenly thought the t/o bearing was matched to the trans vs. the pressure plate. 1 Quote Link to comment
datzenmike Posted April 23, 2016 Report Share Posted April 23, 2016 The throw out bearing are the same. You mean the collars that hold the bearing. 2 Quote Link to comment
KoHeartsGPA Posted April 24, 2016 Report Share Posted April 24, 2016 Now that you got it all squared away....how about you throw us a bone or two..... Oics please! Quote Link to comment
iancshafer Posted April 25, 2016 Author Report Share Posted April 25, 2016 Here are the before and after - installed the right t/o assembly. The bearings do look a little different, but i am guessing that is normal per Mike's earlier comment about them being the same and the T/O collars are different. https://drive.google.com/open?id=0BxFXomNCkdI-ekhSTXFYX0FYRVE Here are some pics of the car, we do endurance racing with her mostly 24 Hrs of Lemons. We are racing at Millville, NJ NJMP on May 14-15th if you are in the area! https://drive.google.com/open?id=0BxFXomNCkdI-aDRvZWJ3dUU4VVE https://drive.google.com/open?id=0BxFXomNCkdI-RlU5TkRCYzZKT1E https://drive.google.com/open?id=0BxFXomNCkdI-RjQyZW5PeUJuSXM https://drive.google.com/open?id=0BxFXomNCkdI-bUk1ZEVmT01CWEk Quote Link to comment
banzai510(hainz) Posted April 25, 2016 Report Share Posted April 25, 2016 I had the same proplem but I bought the t/obearing and collar together and was in wrong box Quote Link to comment
