I suppose they could but went through this with fitting LC cylinders to the RD bottom end. Which is the best option BTW.DOC03 wrote:Thanks Lozza.
Hey in relation to the 400 crank, can they be made ot fit the 350 ?
Ive seen one in the state pretty good nick and can get it relatively cheap ???
The problem is that the RD cylinders are 6mm longer than the LC, 3 of which needs to be at the base of the cylinder, the 3 that need to be on the top of the cylinder is the problem. You can put 6mm spacer under the cylinder but the port timing is something like 220deg on the exhaust which isn't ideal.
Options are to make another sleeve with a 3mm ali plate welded to the top of the LC cylinder before a new cast iron liner is installed. A sneakier option is for an aluminium bronze(same material as det rings) would save a bit of work and the ring would run over it just fine.
Other than that I can copy the RD balnce factor over to the LC no problems.
The air cooled RD rods have a 28mm big end eye with 18 rollers stock LC/RZ has a 29mm eye (14 rollers)they are the best rods (same as TZ's) cylinderical roller bearings handle the high loads and axialy locate the crank better
