That's the way I was thinking :D
Now discovered an issue though......
The rear prop, when fully compressed, is only 1/4" shorter than it needs to be when installed. When the axle is dropped down it doesn't compress any more, but I don't know whether it will bottom out when the axle moves up. I'll have to drop the springs out to find out.
The front prop has plenty of space.
I suspect the engine mounting brackets on the new Richards chassis are not in the right place
Measuring as best I can against the old chassis, they seem to be about 1/4" further back. This would mean the rear prop is nearer full compression and the front more extended.
I've shifted the engine/gearbox as far forwards as the bracket slots allow, but it still doesn't really leave much compression available on the rear prop shaft.
I'm going to move the rear axle as far back as I can. I'll take up any slack in the A-frame bolt holes on the chassis, but it won't make much differance, if any at all.
Update.....
Just popped the rear springs out and jacked the rear axle to full bump travel. The engine/gearbox is being pushed forwards by about 1/4" or maybe even 1/2". The rear prop shaft is bottoming out. Surely this can't be right?
Are there different rear shaft lengths? this one is in a 2.5TD with an LT77 gearbox. Could it be the R380 uses a longer shaft and it's one of those I have?
I've just measured this one at full compression and it's 645mm over the flanges. Has anyone got one lying about they could measure up for me?
Frustration is setting in rapidly!
