AlanT Posted July 10, 2014 Report Share Posted July 10, 2014 Originally in the TR6 forum, seemed to be of general interest. Here are the turned bushes I made to press the bearings and oil seals:https://flic.kr/p/nYRpxDYou can get the spring-ring off with screw-drivers or make some wedges:https://flic.kr/p/oeiKJbFor removing layshaft bearings, the big jaws if the bearing has a gap behind as it should do and the small jaws against the bronze bush to get hold of a bearing thats been pushed too far in:https://flic.kr/p/oghZY9You could tap the races of the new layshaft bearings in with a punch I suppose or pull them in with this:https://flic.kr/p/oga5v3For pressing the mainshaft back through the new bearing, this protects the end, note how I am using aluminium:https://flic.kr/p/nYSoZk And here is a tool for remove/fit the A-type accumulator piston. This is made from standard O-rings and Acetal rod: https://flic.kr/p/ogkEgv This is for remove/fit the A-type OD oil-pump: https://flic.kr/p/nYRp92 There are two more tools, I'll take pictures when I find them.You could probably do without any of this by banging about with drifts and chisels.Would do some damage most likely and this would have taken me a lot longer to do.We had a recent topic here, in which the input shaft had not been fitted right and the car would move a few feet then "lock-up". Tooling like this helps to get the fit right. Quote Link to post Share on other sites
Motorsport Mickey Posted July 10, 2014 Report Share Posted July 10, 2014 Impressive collection Alan, you are in full scale "tool" production and as you say they help to fit the appropriate bearings/seals without damage. I suppose it's a balance between how many times you may use the particular tool, sometimes it may take as long to make the tool as to use a cruder method to do the job. I'm relieved you've written on the rear what the tool is for, I know I'd forget/or misplace it and end up making it twice ! Mick Richards Quote Link to post Share on other sites
AlanT Posted July 10, 2014 Author Report Share Posted July 10, 2014 Lets suppose you damage the race on the layshaft bearing while tapping it in. Now you gbox comes to bits, so you have to take it out and find another one. That is of course if you didn't come to bits at the same time. The effort required to make the tool will now seem trivial. Any small cheap lathe would make these tools and you could get one for a few hundred quid. It would pay for itself in a year or so. Quote Link to post Share on other sites
AlanT Posted July 11, 2014 Author Report Share Posted July 11, 2014 Here are two tools that anyone could make.This one pulls the big bearing with the circlip-groove:https://flic.kr/p/oeXPr5And this one pulls the mainshaft:https://flic.kr/p/ogP3PwBoth work with two lengths of 12mm studding.

Paul Down Posted July 11, 2014 Report Share Posted July 11, 2014 Alan, Most impressive! Have you also made a tool to replace the spring ring on the mainshaft, like removing, this can also be a bit tricky. Strange you should post these as I have just purchased some steel stock to make some wedges and a replacement tool. I agree with you having had no end of trouble with a gearbox that dis-assembly/assembly tools make the job so much easier and you sometimes need more than one go to get everything correct. My troubles were in the main due to a bodged re-condition that the previous owner paid a lot of cash for. Pete Cox has been great sorting out the various problems, and he has 40 years plus experience to call on. Paul Quote Link to post Share on other sites
AlanT Posted July 11, 2014 Author Report Share Posted July 11, 2014 Thats probably what the little part that mystified me is for. Quote Link to post Share on other sites
