My car is coming to the end of its full rebuild, it is now on its wheels for the first time in 5 years, i have bow got minitastic coil springs . I now have nothing to judge ride height, the gearbox sump is about four and a half inches from ground. Can anyone tell me the correct height as this seems low.

No idea what wheels you are using, but the suspension should be off its bump stops and you should be able to slip a hand in between the front wing and the tyre. Numbers are given in the manuals for hydrolastic cars which of course are stock 10 in wheeled cars. Yes there is not much ground clearance between the sump and the ground in stock condition, Aussie build cars have less because they have a sump protector. Its dark outside otherwise I would go out and measure the clearance on OTTO. Jock

Just been out to check and OTTO has 115 mm from the sump plug to the ground, OTTO is a 1968 998 Hydrolastic with stock wheels and the suspension pumped up to the correct height. Jock

Tarija and Santa Cruz, Bolivia Mostly because of speed bumps and gravel roads with high centers, I ended up with mind set to about 10 1/2 inches at the side seams. That gives me about 12 cm to the protector plate I made for the sump.

Wow! thats a serious bit of sump protection, i would point out that it looks like it may impair the cooling around the gearbox fin,s, but i,m aware Richard that you have an oil temp gauge on your car. Thanks guys for input , will check.

Common sense tells me that the drive shaft,s should be parrallel to the surface of the ground,but that cant be right.

Thanks guys for input , will check. Interesting thing, watching the oil temperature. The highest I've been able to get it is about 165ºF (74ºC). Originally I was worried about all the posts on overheating, and only put in a 74ºC thermostat. If it continues this cold in the summer (next few months) I'll replace it with an 82 or so.

Are you running an oil cooler Richard?.

Tarija and Santa Cruz, Bolivia
No oil cooler, just stock. On a couple of occasions when under load at high temps I've turned on the auxiliary fan, but probably did not need it.

Nice one Richard, i was never able to locate a 200 psi gauge (at a sensible price) anyway. Have a good Crimbo out there.

Tarija and Santa Cruz, Bolivia That is the temp gauge. My oil pressure gauge is "T'd" in with the normal sensor and handles the normal oil pressure, usually when cold, dropping to the low 40's when it heats up. For testing the transmission, I just hooked up a gauge temporarily to look at and then pack up. Later served to prove that the fuel pump pressure was too high. Got this at a local electrical and tool store.
