Can someone remind me why are we pulling the crank pulleys off the car for a timing and balance belt job?

If you have mechanical friends who are willing to help you, the 944 v8 is the way to go. There are about 10 guys on this board that could notice 60lbs in a 3000lb car. THere are also affordable things to do to move 60 lbs.

look up 944hybrids or whatever the new board is. RH while once a good place to get information, are basically not doing 944's anymore. Texas performance concepts is it now.

Would love to get another, but have my hands full with the miata v8....

What made your 944 V8 un-trackworthy? Oiling issues? I've been kicking around the idea of finding a 951 with a blown motor and dropping in an L33 for a fun street car with occasional track use.

Oh god no. Here are instructions for everything on the 944 in plain English:

Combine that with the workshop manuals here:

http://www.9ss1.dk/porsche944/garage/workshop.html

That should cover you well. Any questions post them up here, I'm subscribed to the thread and I've owned 924/944's since 2002. Justin's probably owned them longer than me, he definitely has more experience with the 2.5 engine. There's really not much on these cars we haven't touched. Justin's done a full rebuild on a 968 engine, I've done one on a 924, so you're covered from 2.0 to 3.0 litres!

I have to do my t-belt too

To access the crankshaft oil seal. No point doing all this work and leaving the old (probably weeping) crank seal in there to contaminate the new belt and make a mess. The balance shaft and camshaft oil seals should also be replaced for the same reason. Many timing belt kits include all of these.

If you are just doing belts and are trying to do everything on the cheap (because that ALWAYS turns out well!) you can sneak the belts out between the rear cover and the crank gear / pulley without removing them.

Clarks Garage is a daily read for me lately...

To be perfectly honest I am looking for someone to assist me in doing this work.

I will turn the wrenches, get dirty etc...

But some tech support sipping a beer while I slave away would be great.

If there are any services (non sexual...) that i can provide in return, that we can discuss that too.

I'd advise this if:

1. It's a car with unknown service history. Replace the water pump while you're in there. This was done when I bought my car.

2. Every third belt change on a car you've owned that long.

That's fair, but it's worthwhile pointing these things out before getting too deep into it. I've done all these jobs and for an unknown history car it's worth doing it, but like you pointed out, if you are just doing the belts you can slip them out.

So your shopping list nuffy is a front end reseal kit, belt kit, and a waterpump.

Yep...

I have a quote for all the work mentioned for about 2K.

Is it worth attempting this myself at all ?

[chrenan]

If you have the tools and space, absolutely. Post up pictures here if you get stuck and we can walk you through it.

Here's an ongoing thread on my car. It tracks some work from last winter (new oil cooler, new head, headers, belts, etc.). It shows lots of the oily bits you'll be dealing with.

Great thread...

Do you source your parts locally or online ?

Online (with US Post shipping only). I'll pick up the odd small item at the dealer, but very rarely.

[Nufy]

Online Sources other than pelican ?

[chrenan]

I've used all of these over the years with no issues (as well as pelican), they are probably on the list of common sites for many 944 guys:

Awesome...Thanks.

Pulled off my accessory belts and timing covers this afternoon.

I am guessing I have the 46mm water pump







What do you think ?

I need to be sure before I order parts.

[chrenan]

Where the belts are closest together in your picture, there is no guard plate between the water pump pulley (left) and water pump roller (right), that usually means an early water pump. See the guard and late 46 mm roller here:



Easiest way to be sure is just to line up a ruler against the water pump roller and get a rough measurement:



It looks like you may have the early original water pump with a 32 mm roller - while you are in there it might be a good time for a new late style water pump.

[Nufy]

Gotcha.

I was actually measuring the drive pulley on the water pump hence my confusion.

I am also looking for a lower t-belt cover.

It seems the AC compressor blew up and ran the alternator belt into the plastic housing.
Its pretty messed up.

Previous owner installed an AC delete kit but didn't change the belt cover.

Know of one for sale ?

I am in Edmonton this wknd and could meet you somewhere.

Cheers.

[Nufy]

Do you need the slim wrenches to adjust the tensioner pulleys ?

If so where in calgary can I get one / a set ?

Thanks.
