JACK MODIFICATION FOR EASY REAR END LIFTING

I MADE THIS ATTACHMENT FOR MY SEARS JACK WHICH WORKS REALLY WELL;
I USED A CAST IRON PIPE REDUCER (3/4 TO 1/2) FROM HOME DEPOT TO FIT INTO WHERE THE LIFTING PLATE NORMALLY SITS ON THE JACK, DRILLED A NESTING HOLE INTO A 1X6X18 PIECE OF OAK, ONLY DRILL 3/4 OF THE WAY THROUGH THE WOOD. THE PIPE REDUCER IS NOT PERFECTLY ROUND, SO I USED THE DREMEL WITH A SANDING DRUM TO SMOOTH OUT THE PIPE AROUND THE CASTING AREAS AND TO ENLARGE THE HOLE SLIGHTLY IN THE OAK. I USE THIS TO LIFT THE REAR END OF THE TRIUMPH FROM THE T-SHIRT AREA WITHOUT DOING ANY DAMAGE, THE OAK PIECE IS LONG ENOUGH IT REST ON THE FRAME RATHER THAN THE T-SHIRT PORTION; THE LIFTING PIECE SWIVELS SO THAT WHEN JACKING FROM THE SIDE OF THE TRIUMPH THE LIFTING PIECE IS LINED UP AND SQUARE ON THE FRAME FOR A GOOD SOLID JACKING POINT. AFTER THE TR IS LIFTED LOWER ONTO JACK STANDS FOR SAFETY REASONS.
THANKS,

Not having a TR6, what is the T-shirt area?
By the by what area do TR3 owners use for rear jack points? (No thread steal...on subject)...
 
The original TR3A jack used through the hole in the floor was supposed to lift an entire side of the car, but often just lifted one end, so you mightn't get the flat tyre raised. I've often wondered if having the tank full would balance out the lift with the engine weight.

A lightweight scissor jack is a good substitute, as it can be wrapped and carried in the spare tyre well. A simple thin block of wood between the jack and the chassis suffices as a pad, but I've seen all sorts of innovative brackets made up for that job.

Regards,

Viv.
 
One challenge with a scissors jack is getting it under the frame once you have a flat tire.

I guess I've been lucky with the stock jack as it has always lifted both wheels though I suppose I could have used the passenger for ballast (after all, passengers who can't or won't navigate are essentially ballast).
 
I have found that the screw jack from a Porsche 944 works great on my TR-3 and my TR-4. The screw jacks are aluminum and so are the handles. They are very flat and very light weight and are made to lift a 2600lb. car. I usualy pay $20. to $25. from a wrecking yard. While your looking for Porsche 944 parts, I also buy their sunroof bags for my TR-3 sidecurtains and a storage bag for my top or tonneau cover. Perfect for both side curtains and normal cost at wrecking yard is $20.00. Maxda second generation RX-7 (1986 to 1990) also use an Aluminum screw jack. Cost in wrecking yard is about the same. good luck, Bill C. Mesa, Az.
 
The TR3 side jack does sometimes lift one wheel first for me, but I've found that if I just keep going, the other wheel comes up as well. It's kind of slow though, so I only use it on the road.

Jacking the TR3 from the rear with a floor jack, I just jack under the larger of the two cross pieces in the frame. The stock jaw on the jack engages with the curve of the tube to help keep the car on the jack ... I've used that to move the car around in the garage.

Friend of mine used to keep 3 Triumphs in a 2 car garage; his TR3 had to be slid sideways on the jack to make room for the Stag & GT6.
