Title: Help - Engine Angles ? Post by: Blown_FC on May 25, 2004, 09:50:44 PM Can anyone please help......
I trial fitted my red 202 and trimatic last night, and mounted the trimatic neck on the gearbox support that is part of my CRS Chassis Kit......so the engine is sitting on it's mounts, as is the gearbox......BUT....the engine seems to be sitting on a fair slant at the back. (ie)....it almost as if the CRS chassis kit gearbox support bar is to low and needs to be raised a good 50mm odd to help level up the engine. The gearbox neck has ( what I think ) is the correct rubber mounting block attached and is resting on the CRS crossmember, but the angles just doesn't look right. Does the engine have to be dead level ??? Should I maybe fabricate a 50mm spacer to go between the rubber mount and the CRS support ? Any ideas pics and info is greatly appreciated ! Oh yeah....I drove this car when I bought it, and it had a red motor, same trimatic, same HR front end....so the only change in the set up is the CRS kit which supports the gearbox !

( in lay mans terms) the engine will always have a slight rear tilt of this is so. To get this right on an EH, we had a spacer block made up that sat under the gearbox rubber mount. initially I used block of wood, then took it to the local machining shop and asks for it to be made in metal.

I had in same trouble with mine. The motor is on a slight slant but i had to get a Aluminium block made up to sit between the crossmember & the gearbox mount to get the right angle.

I might just whack a spirit level underneath the gearbox pan and level the unit to that, which would then give a level drive shaft from the gearbox ( if you know what I mean)...then get a spacer made up accordingly.

we were really scientific and got a broom handle, and held it up to the diff pinion and gearbox end.. when it looked straight as it could get we set it there. I dont think there was a spirit level handy anyways! Cheers Ed Title: Re: Help - Engine Angles ? Post by: Blown_FC on May 25, 2004, 10:15:30 PM Broom Handle ?
Well, I guess that's one way of saving weight on a prop shaft ! (lol) Mark Title: Re: Help - Engine Angles ? Post by: Effie C on May 26, 2004, 02:30:26 AM Mark
Put your spirit level on the top of the carburettor, the float bowl should be level when the motor is installed, the rest will be where they fall. If you level the gearbox and the carbie float is not level you will have all sorts of fuel problems. For what is worth the motor should be on a slight downward angle at the back, Holden designed them this way so that when you have a head on the motor tears out and goes under the car and not thru your legs. As to keeping the prop shaft straight close enough is good enough, that is what the universal joint is for (Don't want to do them out of a job) ::) Good Luck John M |
