New belts, rollers and tensioners - and colourful pulleys!

It seems like the end is insight now with the front end rebuilt and refreshed!

After resealing the balance shafts the next task was to fit the new rollers and belts. Firstly all the new rollers were easily bolted up and torqued down. I sourced most of the parts from GSF.

First order of the day was to refit the crankshaft gear - I bagan by heating it on the oven to make it expand so it would slip over the crankshaft easier:

Be sure to fit the splined insert correctly or the washer and gear won't sit flush with the oil pump, then gently tap the key back into the recess on the crankshaft. I smoothed mine of with a small file to remove the burs.

Remove the gear from the oven and slide to onto the crankshaft - a little lube helps this fitting process too.

With the crankshaft gear fitted the rest goes on fairly straightforward.

I'd had the tensioner media blasted and refreshed with some high temp paint - looks a darn sight better than the rusty thing it was before! It works well too.

Before...

...after media blasting and a spray of paint.

The nervous bit was ensuring the camshaft gear and flywheel remained at Top Dead Centre whilst attaching the new cambelt - there mustn't be any slack between the camshaft and crankshaft gears.

It took a couple of attempts but it's not a difficult task by any means. With it on I released the tensioner to tighten the cambelt and it was done!

At this point I wondered again about refitting the balance shaft belt - I've read so many conflicting reports about balance shaft deletes. Leaving it stock means the engine should run smoother; leaving it off means the motor will produce more power due to the lack of parasitic loss not having to spin the balance shafts. I decided in favor of smoothness until I need to remove the bottom end when I can check the condition of the oil pick up pipe - which without balance shafts might break due to higher vibration. The end result being a disaster...So stock it remains this end.

With that taken care of it was time to test fit some more powder coated bits before dropping the engine back in...

The main pulley got blasted and spray painted (this pulley can't be powder coated as it has a rubber damper insert which would melt in the furnace):

...and so did the engine side alternator pulley - but in yellow!

Sunny!

Engine out the top - Easy Peasy

After reading numerous posts, the Porsche workshop manual and Clarks Garage step-by-step engine removal guide - I felt confident enough to tackle the job. But I wanted to remove the engine from the top. As I discovered, it was pretty straight forward even for a novice! Result. I wanted to avoid removing the cross member and disturb the front suspension to do something I was convinced could be done easier from the top. Posts such as this one convinced me to give it a go at least. And I'm glad I did. In summary I was able to remove the engine from the top without needing to remove the bonnet/hood; torque tube; transaxle; bellhousing; clutch; clutch slave cylinder; cross member; front suspension; and radiator. Contrary to many so called internet experts opinions and many confusing threads this was painless and without dread. All that was necessary to remove was the starter; power steering pump and alternator (I figured to make the bottom of the engine narrower); intak...

Bellhousing & Clutch fork removal

Removing the bellhousing from the Porsche 944 engine is not as complicated as it may seem - such as in this situation with my replacement engine. When I removed the original engine I detached it from the bellhousing in the car and removed the clutch pressure plate bolts through the starter motor hole - see my other post for details . In this case I decided to remove the clutch fork pivot shaft bolt. Begin by removing the four 17mm bellhousing bolts - you'll find that the bellhousing doesn't detach completely from the engine. It'll feel like its hooking on something. That something is the clutch fork pivot shaft inside the bellhousing. The bellhousing will be loose enough to rotate - turn it 180 degrees and peek through the access port which is now on top - this is what you'll see: If the engine is still in car you'll be looking at this from underneath. The pivot shaft needs to be extracted from the clutch fork. It's held in place by a small bolt on the...

New Steering shaft bearing Nightmare removal

In my quest to tighten up the handling on the 944, I bought a new Needle Bearing from Porsche in an attempt to eliminate the fore-aft play in the steering at the top universal joint. The part number for the replacement is 477.419.059 and costs £88.86 posted from an OPC. Nothing like the effort required to actually remove the old one... I began the process by reading section 48 of Porsche Workshop manual. It appeared a simple enough process but two things bothered me: firstly, it required a chisel to remove a shear bolt (which in my limited experience never "shear"; and secondly a drill to remove two screws from the ignition lock. I was bothered because a quick look under the dashboard made it quite obvious that whoever had written the manual hadn't performed this task - well not without a dashboard in place that's for sure. I was bothered before I'd even started. Furthermore, the manual doesn't detail the replacement of this bearing at all - just the rem...
