Hey, just a quick question about the tensioner tool. I put in a set of FP2's last night and I need to get the timing belt back over the cam gears. I don't have time to get the "special tool" and I've read about using the battery tie down bolt (but that's on a 1g, I have a 2g). So my question is, is the tool just a long piece of 8mm 1.25 pitch rod/bolt? Also, do you just put it in the back plugged spot (which I can't seem to find :notgood: ) and turn it to take off the tension? After I get the belt back on and marks lined up, do I just turn the tension the opposite way and then measure the gap by the pulley?
Thanks for the help.
 
yes, that the tool i s basically a long 8mm molt , you can just get two bolts that fit onto the 8mm bolt and use them as a locking bolt at the end, the hole for the tool is right above the tensioner pulley(the pulley with the blue circle in it).the hole is small but i find that your fingers are some times better eyes then your eyes, so just feel around for it.to messure the gap stick an allen (not sure what size check on vfaq) wrench between the top of the tensoiner(looks like an "L") and the tensioner arm you barley be able to move the arm in and out. it all sound a liitle confusing but trust me it not once you get hands on.hope this helps.
 
my 2 cents worth on TB Timing & Tensioning...

I just bought some 8MM ALLTHREAD at a Hardware Store & double nutted 2 Nuts at the end for a Tool.

- If you were to watch what the TB does when tensioned you'd see that the TB literally "rolls" into Time as the Tensioner takes out the Slack at the proper point & pulls slack out of the front side of the TB loop.

- Set Sprockets & Balance Shafts per - http://vfaq.com/mods/timingbelt-1G.html - EXCEPT....

- It MAY be necessary to BIAS = Mis-Time Exhaust Cam Sprocket ONE Tooth Clockwise - Belt Tensioning process will roll it back into time.

-Don't forget to apply Soft Loctite or RTV to Tensioner Fasteners & apply Final Torque.

-Run ALLTHREAD Tool in until Tensioner Arm Bottoms against Tensioner Rod - PULL GRENADE PIN - Then run ALLTHREAD tool in until Tensioner Arm just Bottoms against Tensioner Body.

-Basically you preload the Eccentric Tension Pulley enough to achieve the correct Gap between Tension Arm & Tensioner Body - SO...

-PRE-LOAD the Eccentric Tension Pulley & snug Pulley Bolt (I used soft Loctite on this Bolt too) - My favorite Tool to apply the Load on the Pulley is a long good quality Square Shanked Screwdriver that lays on one of the Water Pump Bolt Heads nicely for leverage.

-Back off ALLTHREAD TOOL a few Turns thus letting the Tensioner FULLY Tension the T/Belt - but you can leave ALLTHREAD TOOL in place.

- Check Belt Timing Marks - This is where you may see that you have to regroup on initial Timing Belt installation & Bias the Belt as I said at First - Note that of course only every OTHER time Crank Timing Marks line up wil Cam Sprocket Dowels be Up.

- Spin Crank 6 Turns so Timing Belt can take it's initial SEAT in Sprocket Grooves.

- Check Tension setting by trying to reinsert Grenade Pin in Tensioner & / or check gap size with Drill Bit.

- If gap is too large you have UNDER TENSIONED BELT, run ALLTHREAD Tool back in to FULLY depress Tensioner and put MORE PRE-LOAD under Tensioner Pulley with long Screwdriver & SIMULTANEOUSLY loosen Pulley Bolt putting more Tension on Belt, & then Snug up Pulley Bolt while applying Load.

-Back off ALLTHREAD TOOL a few Turns thus letting the Tensioner FULLY Tension the T/Belt - but you can leave ALLTHREAD TOOL in place backed off & not touching Tensioner.

- Check Tension setting by trying to reinsert Grenade Pin in Tensioner & / or check gap size with Drill Bit.

- If Grenade Pin checks Sat apply Final Torque to Tension Pulley Bolt & RECHECK TENSION SETTING .

- If Gap is too small you have OVER-TENSIONED Belt - Back off Tension Pulley Pre-Load a little & RECHECK TENSION SETTING.

- Install just enuff Belts & Pulleys to run Water Pump - attach Battery charger & run Motor with NO Timing Covers & no Alternator - you can leave ALLTHREAD TOOL backed off & of course not touching Tensioner while you do this.

- Immediately when you get it running Check Oil Pressure & then Check for Coolant & Oil Leaks - Check your new Water Pump & Water Pump O Ring, etc, etc... Be ready to Reset Base Timing & Base Idle as it comes up to Full Running Temp - Start off with CAS at middle of adjustment if you don't know where it was.

- After a good long idle or 2 re-check Tension with Grenade Pin, Remove ALLTHREAD tool & Button up Covers if all is SAT - Expect to see one good stretch as Belt heats up & "sets" in the Pulleys & hence TB may need one good re-setting after initial idle.
