<img src="graemlins/jumper.gif" border="0" alt="[jumper]" /> I am getting ready to change the timing and balance belts on my 86NA (~130,000 miles), just as preventative maintenance. I know I need the following:
Balance Belt(94410221902), Timing belt(94410515704), Balance Belt Roller(94410227706), Timing Belt Adj Roller(94410502704), Balance Belt Adj Roller(94410202507), Timing Belt Roller(94410527302).

I already have an updated waterpump, and I am also planing on changing the ps belt and ac belts. Going through the diagrams I have, it also looks like there are some o-rings or seals, that I can replace, but I don't know there part number or size.

Please If anyone has any suggestions on what else I should replace let me know. The seals on the shafts, are they easy to change? Are there any tricky things to look out for, that the manual doesn't cover?

thanks in advance

Thermostat. Have fun with the snap ring....

I did not. I gave up. I'm removing the water pump and making a massive mess while doing so.

On the original post ... if you are leaking oil at the front of the engine, this would be a great time to re-do the seals (b-shafts, crank, and cam). The cost of the seals is pretty low (relatively speaking), but getting the cam gear off can sometimes be a pain. Getting the b-shaft gears off requires a special tool. And removing/installing the crank pulley will require a bunch of torque.

I just got my thermostat out - took two mirrors, an awl, and broke two circlip pliers in the process.
