IMS tools

[Black_on_black]

Hi

would be glad if someone could help me out with how I use these tools that came with my IMS bearing replacement kit (preventative!). I will be in a shop to remove the trans and flywheel, but the IMS bearing I'm doing myself. Perhaps there are some step by step pics I just haven't been able to search out?

TIA

Mike

EDIT - forgot to say, this is a 2002 C4S manual approx 55k miles

Take a look at this.

It's close to your engine, but not exact, that one is a 5 chain and smaller (for a boxster).

But most of it is the same, example you must lock cams. I repeat. Don't just remove the ims flange cover without having the cams locked with your cam locking tools.

I don’t mean to sound patronizing, but if you do not know how to use these tools, perhaps it would be better to either let someone that does handle it, or at least be there to guide you through the process……………..

Thanks for the links.

No worries, I am not the newbie it sounds like, just haven't done this particular one before. The tools seem overkill for a simple bearing extraction and gentle tapping in place...but given the links I get it now.

I suppose tools 4 + 5 looking from the left are to lock the cams?

Common sense, go slow and stop and ask when not going to plan is my general approach, not intending to screw the engine even though its the first time I do this job.

Yes, #4 & 5 are cam holding tools.

The 5 chain motors are easier. Locking the accessory belt pully and pulling 2 of the 3 tensioners will suffice. Done it personally. Many others have done it too.

But the 3 chain motors have less " drag" and can unintentionally rotate when the bearing is pulled, throwing your timing off. Pulling the 3 tensioners and locking the cams might be your safest approach on a 3 chain motor.

It's an easy job if you do your research and go slow. Rennlist has lots of DIY writeups.

FYI:

if you purchased the IMS Retro Kit from L&N Engineering they will only honor/accept a limited warranty by them ONLY if a Qualified/Certified Mechanic installs the kit and only if on IMS retro kits installed as a preventive maintenance only when the original bearing has not failed. I recieved my kit today and in the box there is a Warranty Worksheet explaining just that. Good Luck.

Thanks guys - it isn't an LNE kit. Not to go into the debate, but I will install an original spec metal ball bearing with an "upgraded" seal that doesn't degrade apparently. Next time i'm in there (five years, another 50k miles or so?) I'll swap it again as part of routine maintenance.

where did you buy these tools? i may do the same with the oem bearing. will you sell your set? thx

[Black_on_black]

I bought them from Utzon.se B) The tools are on an exchange basis so will send them back.

FWIW did the job today. It was simple once the guy had removed the transmission. Bearing came out easily, new one in the feeezer, a bit of heat on the ims tube and it went in with only light persuasion. Loctite and tightened everything up.

As a data point, the original IMS bearing was fine, and feels like new. It would have lasted the life of the engine. At least now I know it will go for ten years easily and I can sleep well :)

$2k spent well then...(don't tell my wife...) :rolleyes:
