18rg 2tg compatibility

**Noof** · 17-10-2008, 04:29 PM

Hey all,
Want to know whether the timing gear from an 18rg is compatible with the 2tg?
Can I use the gears off the cams and timing chain from the 18 in the 2tg?
Pretty sure that the chain would be the wrong length but the cam gears?
Cheers

there are 2 different types of 18rg cam gears. one set is held in by 3 bolts and the other type is held in by one big bolt in the center of the gear.
if the cam gears are the type that are held in by a dowel on the camshaft and 3 bolts than i think they are the same between 2tg and 18rg.
i don't think the chains are the same.

2T-G cam sprocket left, 18R-G right.

Hmmm guess that is a no then! Thanks.
Might have to look at swapping them for 2tg ones though?
Either that or sticking with the 18rg in the ta22?
Still undecided..
Thanks to those who answered.

as i said mate the early 18rgs had the same gears it is just the later and more common ones that had the big single bolt. if the numbers on your 18rg head are 11111-88250 or higher than you will have the gears that aren't interchangeable with the 2tg ones.
