I own a TR250 that I am having problems with. The car had 185/65r 15 tires on it when purchased. I knew that these were not the right size tires and it was causing my Speedo to be off. Well I recentl

Check your tach against a known good tach as the tachs can become inaccurate over time. An electric tach can be used to test with. Your car should be running about 3000 rpm at 60 mph in top gear (as

Could be the tach is wrong. Should be closer to 2900 rpm (with 205/70-15 tires & 3.7 gears), and reading 600 rpm high isn't terribly uncommon for these old mechanical tachs. Lots of ways. If you jac

Yes, Please explain. The ratio is what it is and therefore I don't understand what you mean by "off by a factor of 2". Joe --Original Message-- From: triumphs-bounces+spitlist=cox.net@autox.team.net

If you had a welded diff where the axles on each side were NOT free to move indepentently then you'd be fine with the simple test. But since you hold one wheel steady and turn the other, you are mak

In your example, you would not be able to keep 0ne wheel stationary because a locked (welded) diff would force both wheels to move together. I tried several different methods a few years ago to see

That is precisely the procedure that I proposed. However, I did mention that you ought to keep one wheel from spinning so that you remove the differential effect. Joe --Original Message-- From: triu

Sheesh. If both axles turn together at the same rate, so there is no difference in their movement relative to each other, then there is no differential effect. If you hold one wheel stationary and t

I am pretty sure that if you do not secure one wheel, one will spin backward relative to the other with an open diff. Don't ask me to explain it but that is what I have noticed when I tried it. I am
