6.2/6.5 Fluidampr?

[More Power]

Hello

I am wondering if anyone knows if its ok or not to glue a set of magnets onto a Fluidamper harmonic balancer? I have started to get a little interested in sticking an Isspro tacometer on my truck and I know they use a pair of magnets and a hall effect sensor to generate a signal. I am starting to get a little worried about my origonal balancer because I am getting a pulsing vibration throughout the truck which I think is steming from the engine. Kind of along the same lines, does anyone have any advice for installing a gear drive set at the same time as I do the damper?

Thanks

The rather small magnets Isspro uses shouldn't cause a problem when installed as indicated in the instructions. Some vibrations found in these engines could be due to an aging harmonic damper. It could also be attributed to a loose timing chain - causing variations in injection timing. It could also be due to an imbalance in the injectors or cylinder compression.

Installing the gear drive timing set has been discussed at great length here in the board. A few searches should turn up a lot of reading.

I'm using a Fluidamper with an Isspro tach, the only problem I have to report is that apparently I glued poorly one of the magnets and it flew away. So I'm having to multiply by 2 the tach readings. Ha.
My only excuse it's that the Fluidampr surface is so smooth that is not a good bonding surface for the glue.
No vibrations whatsoever even with only one magnet.

If you don't want to glue the magnets to the damper you can glue them to the flywheel/flexplate and mount the hall effect sensor inside the bellhousing.
I did that on a Toyota 4.2 L6 TD from a '95 Land Cruiser in a friends Dodge M-37 with an Isspro tach.

Hey wanted to add to this. I just read the entire thing and my question is...Anyone running one of these(like I am)..Any issues with extremly cold weather ? Will the motor be out of balance in the morning ? Mine felt kinda funny the other morning after 1deg F over night but it could have been in my mind.
Anyone have input on how cold weather affects them ?

I've wondered that too, but haven't looked into it because I believe it's a minor point. The silicone fluid can operate under a very wide temperature range - perhaps moreso than the OE rubber elastomer.

Near zero F. causes most diesel engines to start or begin running somewhat rough till the fire is lit and combusting normally in all eight. I recommend using the block heater (for at least a couple of hours) before the first start when it's that cold. That'll cure the roughness... Jim

On edit: I'm putting together a 6.5 that'll have the FD. It'll probably be spring before it's on the road, but I'll know more next winter.

I just got back from Crested Butte, last day when we left thermometer on RV Mirror read -23F. I was plugged in all night and started and after warming up noticed nothing unusual. Don't think cold bothered the Fluidamper.

OK. Good too see someone else's results. I do use the block heater whenever possible. Hate the way they sound cold..

Update.
I spoke with a tech at Fluidampr. They are in Buffalo NY and said unless it gets down to around -40f don't worry about it.

Though it's taken much longer than I expected to complete the project, we've been driving the Blazer and rebuilt 6.5 (with Fluidampr) since last fall (fall-2021). The engine is very smooth running, and I have not noticed any damper-related roughness this past winter as a result of cold temps.... though it didn't get driven much during the coldest days that winter provided.

Out of curiosity, from time to time I have looked at the damper's outer circumference while the engine was idling. It was always spinning dead true, without a hint of wobble that can sometimes be seen in a factory type damper. The serpentine belt also seems to spin around the pulleys with less flapping.

All in all, I'm happy with the FD.
