Wedges

[Viv James TraX Interconnect (Pty.) Ltd]

Joe, Barry Morton here in CT had the same problem when he went Datsun. He inserted reversed wedges with great success. I have done this on my new car which is not yet on the road and will soon do the same on my black one. Both have the Datsun box. The black car steers fine but it could do with a bit more self centering action. Alex Stewart has just fitted a Datsun Box and having completed the Milligan Rally last week also found a tendency to wander particularly with a luggage load. He is going to do the Morton Mod.

Has anyone used the Datsun box on a TA? I use mine for rallying and am thinking of fitting 16" wheels with 550/16 tyres at the front. I am worried that this will cause problems with the original stearing box, ie. magnify the play. Regards Brian -----Urspr ngliche Nachricht----- Von: Viv James TraX Interconnect (Pty.)

I fitted a VW Beetle steering box to my TC per Bill Bollendonks article and found that reversing the wedges to the front was necessary. The front axle beam's castor and camber are correct and the TC tracked straight and true (only on a good smooth road), tho the steering wheel had lots of play. Lots of play from a Bishop cam box that was brand new in 1975. 20,000 miles and it became a piece of junk! The VW Beetle box has so little friction I had to reverse the wedges to get the feel back into the steering wheel. The TC goes where I point it and the VW box should last well over 150,000 miles. I agree with Brian....."you Bishop cam boys don't know what you are missing!" Yea....I used to be an originalist in my early TC years ....but I got over it! BTW I am told this VW box dates back to the beginning of Beetle production (at least post war) and so that makes the Beetle box contemporary to the TC! ......and it has an arm like Goliath's ...The original arm busted on me in 1968 just after returning from a twisty mountain road!

There are none that I know of here in Cape Town. Space may be a problem. Its a tight squeeze in the TC between the exhaust and the front engine mount. There might also be a problem with the drop arm clearing the engine/sump. By the way, on my black car I used a Nissan 1400 pick-up steering which seems to be identical to the old 1200 Datsun box.

Bruce, 1. Standard Bishop Cam box - chuck wedges out. 2. Datsun steering - put wedges back thick end forward. 3. If you want original, standard steering box and thin end forward. I've done them all in the order 3, 1, 2. Forget the science. This is all you need to know. Cheers Viv

Again, thanks for all the info. My wedges [b][i]are[/i][/b] in backwards. I'm going to try removing them altogether first! Regards, Bruce Woodson

Hi, I agree with Viv. I have the standard Bishop Cam box and after fitting new shocks removed the wedges and my car steers well. The tyres are Firestone and although narrow in appearance are fine. I lost the sender who enquired about the MORRIS 1000 diff. so will answer here. The car has done a couple of long runs and goes really well. The higher diff. doesn't have any adverse effect and when running with TDs can keep up with them up-hill in top gear. One thing I'm trying to reconcile is the MPH/1000 RPM. A friends TD was checked against my Beemer (he also has a 4.55/1 diff. and at 100KPH say 62.5 MPH his car was doing 4000 RPM. a week later I followed him in my TC and at 100KPH my rev counter showed 3000 RPM which seems very high. I have checked my rev. counter against an electronic one and it reads fairly accurately. Clem

hi Clem - if your tyres have the same circumference as original Dunlops, then the 4.55 diff should give 17.84 mph/1000 rpm: 15.84(5.125/4.55) so your revs at 62.5 mph should be almost exactly 3,500 there are so many different tyres fitted to TDs, that probably no two are the same (tyre pressures also make a difference). ocTagonally TCRoger Clem Vernon wrote:

Roger: You are so right about different tyre sizes. I have 4.3 gears in my TD with 165R15 radial tyres. I am doing about 60 MPH at 3600RPM. The rolling radius is the thing to check. Most good 165 X 15 radials are about 813 to 820 revs per mile. The original bias plys were about 775 revs per mile. Skip....................................
