Put it in first, then fire up the engine to get going, then carefully shift up and down with double-clutching. But, I can say from experience that you can get home when this happens. So, if you lose either hydraulic system, you lose both. However, these Sprites (and MG Midgets, or Spridgets) take that one step further by having a single chamber for both brakes and clutch. Well, I guess I grew up in an era of single chambers, so don't worry about it that much. In a couple other projects (Model-A hydraulic brake conversion and MG-J2 build), I've installed single chamber brake master cylinders, and had folks email me about the safety of not having dual chambers like modern cars. They start out at 4-3/16" long, and need to be shortened to 3-11/16" long. Here's a shot of the two push-rods, with one of them shortened. Place and the clutch and brake operation is much improved now! When I shortened those, all the pieces fell into Operation, and also to let the fluid bleed back into the master cylinder so the brakes don't start to bind when warm.Īfter some research, I found that these later master cylinders had push-rods that areĪ full 1/2" shorter than the earlier ones. I installed one of these later master cylinders, and while it solved the hard clutch issue, I had a great deal of difficulty making the adjustments for proper This gives you about 36% better leverage on both the brakes and clutch. Have a master cylinder with a smaller bore than the original master cylinder. (very nice people), I found that the later Sprites, the ones with disk brakes on the front, Hard to press and regulate for smooth operation. However, while satisfied with the conversion in general, I found the clutch still Larger diameter than the stock Datsun slave cylinder to make the clutch work betterĪfter the transplant, so I used one of those. The Rivergate folks offer a slave-cylinder with a I opted for the Rivergate kit which includes This leads to high RPM cruising - 4,000 RPM at 60 MPH.Ī Datsun 210 5-speed conversion gives it synchro in first and an nice overdriveĥth gear for more relaxed cruising. However, the original transmission has no synchro in first, is fragile, and has a 1:1 top gear. Before I bought it, it was converted to a 1275 cc Austin motor from a later Sprite, which is a bolt-in operation, and gives it a few more beans for keeping up They only weigh 1440 lbs, they don't need a lot. These cars, from the factory, only have 43 HP from a 948cc Austin motor. In Europe and the UK, they are called Frog-Eye Sprites. But, they are nimble, fun to drive, economical, relatively reliable, and have features unusual for the time (Bugeyes were built from '58-'61) such as unibody construction and rack-and-pinion steering. To save costs, there is no trunk (boot) lid, no outside door latches, or no roll-up windows. Sprites like this are the picture of simplicity. I've had several through the years, the first one which I bought for $200 in 1968. Here's my Bugeye Sprite, I've had it for a lot of years, originally buying it inĪustin Texas and driving it home over the Rockies back to the Seattle area. I'm including this since it might help others researching the same While this isn't much of a project, it includes some information I've learned about Datsun 5-speedĬonversions to a Sprite.
