1955 Austin Healey

Recommended Posts

Thanks for the links Fellows. Here is some photos... You can see teeth missing from the lay gear, The layshaft and bushings are worn from lack of lube. looks to be a common problem with these. I don't trust the gear that drove the broken one. Someone had to run her hard to break it up like this. Dandy Dave!

"Running her hard" is what sports cars used to be all about. That, and the wonderful sounds that they made while running hard, especially a Big Healey. I had an MGB for almost forty years but running that thing hard only produced annoying noise. I eventually got so sick of it, I practically gave it away last summer. No regrets but it sure was a pretty car.

You might try a company called Quantum Mechanics in Connecticut who rerbuild transmissions for Big Healeys. I think they have a website and they used to run an ad in the magazine of the Austin Healey Club of America.

Yes. I have looked at the Moss catalog and they list the Gears we need as NA. (Not Available). We will need other stuff also and some of it they have. First we need to track down, and replace the broken the gears. Dandy Dave!

If all else fails, these guys can make one for you.

Well we are back at this Austin Healey. A Friend of a Friend tracked down an NOS laygear for us. I had to fit a new syncro to one of the gears and machine it. Photos to come. Dandy Dave!

Check with Russ Thompson at Thompson British Car, here in SoCal. He has been a Healey guru for 40 years. 818-256-0693. I used to work for him and there is no one who knows big Healeys better than Russ. If he can't point you in the right direction, nobody can.

Photos... Had to heat the Syncro to fit first. Boiled in in oil to 250 F. Then set it up in the hydraulic press and pushed it home. After that the finish diameter and taper needed to be turned. I had to make a plug to support the shaft in the lathe. The taper was achieved with a taper attachment. Moving right along. We should be driving this car soon. Dandy Dave!

Here is the NOS parts and another photo of the machining process. NOS second gear and Laygear. New Laygear shaft and ball bearings. Machining these parts precisely is not as easy as it looks. Tolerances had to be within 0.001". It takes a lot more time preparing than it does to do the actual cut. Dandy Dave!

Thanks for the info. We already tracked down what we need for now. Dandy Dave!

Laygear = = Cluster Gear ?

In my yout I wanted a TR3. Found a Jag that was in my budget. Then found out why.

Yup, been wrenching on stuff for 40+ years and I still find out that I don't know nothing... Laygear = british car terminology. So you have an input shaft. And then below that you have a Laygear. Transfer the power back to the output shaft. This is a transmission that is built on a 4 Speed and one reverse design. Trouble is that first is locked out or omitted. So to confuse the issue, low gear is 2cd. Intermediate is third or 2cnd in a three speed. And lock up, or 1 to 1, is 4th, or third in a three speed. Don't you just love British Sports Cars and terminology? Dandy Dave!

Actually, you have a "first motion shaft", a "laygear" and "layshaft", a "mainshaft", "baulk rings" and other "bits and bobs" in the "gearbox", which, of course, transmits power through the "propeller shaft" to the "crown wheel and pinion".

I spent too many years behind the parts counter at British dealerships

Way back in 1967 a fellow classmate purchased a very well used 1956 Healey. It was a blast to drive, and the windshield folded down. As A result we got chased by the local police for not having it up however; he couldn't catch us on the back country roads! Still remember that day as if were yesterday!

Beautiful car and good luck with it.

Was a time in my youth when I thought I couldn't live without a 3000 but I had to settle for a beat up Bug Eyed Sprite.

Well back around the block with this project and we are finally making head way. The NOS gear sent turned out the be low gear, or Second gear in a 4 speed. Again, this is a three speed based on a 4 speed design. Lack of communication and a middle man not checking the numbers I provided. We needed intermediate, or third gear in a 4 speed design. The wrong gear was sent back and then the search was on once again. We finally located a gear and now I am assembling the transmission. Whew. what a ton of trouble this has been. The worst part is winter has settled in here so I am not sure how soon we will be driving it. At least it is in a heated shop. Dandy Dave!

Do you still want your dream car? I have a 54 BN1 that needs restoring and a loving home. I always thought the AH100's were the best styled motorcars ever made in Ole Blimey.

PM me.

I got all the gears, Syncros , spacers, bushing's, (Or bush's as they say over there.) shafts, forks, springs and balls, bearings, and other odd pieces back in that tranny yesterday. What a Jig saw puzzle. It only goes together one way and in one combination. Still have to get the overdrive on and then get it in the car. Makes me dizzy just thinking about the assembly process of that transmission. :P Dandy Dave!
