I have my De Dion out right now and I have noticed that one wheel bearing spins like a champ, while the other side spins more reluctantly. The reluctant side feels like the bearing is dry compared to the good side. I am trying to push forward and avoid the "while I have this apart" mentali...

Update: After moving parts around for a while, I am just going with the orientation shown in the second photo. I suspect that it is not the correct way to to go, but that is the only way it seems to fit.

I am working on installing some vented rotors on my transaxle and I am struggling with fitment. Every brake rotor I have ever installed had the thicker side facing in, but in this instance there does not seem to be enough room on the inside piston when I install them that way. Which way is correct? ...

Yes, we agree about the toe being the inner diameter. Im planning to take the new synchros off of the other gear set and install them in the transaxle from the second set of photos. That will be the transaxle that goes back into my car. I will continue to fix the one with the worn shim at a later da...

I read in an automotive technician text book that the pattern shifts when it is taken under load. When i marked my gears, I spun the pinion by hand without putting any load on it. I had been under the impression that adding a load would only make the pattern easier to read. Based on the illustration...

Top photo shows the drive side. It looks to me like the contact is a little close to the toe, though I could be wrong as i am not experienced. If it is too close to the toe, does that mean I should adjust backlash and/or move the pinion away from the center of the diff? (Not that I have any such cap...

I checked the pattern on my spare Platinum ring and pinion... It looks to me like this pinion is set a little too deep. I am disappointed because I had hoped that it would look better. Both of my Platinum transaxles came out of working cars that I drove. I noticed nothing amiss with either of them (...

Surely they are available somewhere... I know of one well known racer who has told me he would sell me a single pinion shim for 80usd if he had one the right size. . He seemed reluctant to even let a single shim out of his collection go. It seemed a little expensive to me. It would be ok if I could ...

Mats, Thanks for the suggestions. I had the hardness of the original shim tested and it seemed to be made of the same material as the nissan shims I found. What I had not considered was the possibility that the original shim's wear had compromised its hardness. I suppose I should go back to trying t...

I am trying to rebuild a Platinum transaxle right now. On disassembly, I discovered that the pinion shim was badly worn. I found some shims from the Nissan parts bin that are close to the correct size. The shaft of the pinion is 1.1735in on the spot that the shim rests. The original shim has an ID o...

The rear flywheel (gearbox flywheel) is a zero balanced unit. If you get your engine's lower end balanced, you shouldnt have any more problems. The gearbox would be fine as it is right now.

Looks like the custom warm air intake that my car's PO engineered. It caused the car to miss terribly on hot days.

I am currently looking at having my stock flywheel machined. I am planning to have the bottom end balanced as a unit. Has anyone in the US done this recently? I am wondering how much it generally costs.

I have been looking for v6 valve guides and seals from the usual US suppliers. One thing that has me scratching my head is the option of using teflon (coated?) valve seals. I have read that some people have had problems with these, but the problem may have been due to those parties using them with t...

These types of difficulties are usually related to the shift linkage rather than the gearbox. Before you start looking for a new gearbox, inspect the shift linkage itself. If the splined connection at the clutch isnt tightened down all the way, it affects shifter travel.
