Looks like you get to learn how to pull the engine and steering rack as a Christmas present.

Hi Phillip
Having now taken motor out twice already, I can offer assistance if required.
I replaced the rubbers in my Centa last year? Simply because I was already in there. The old ones were in perfect condition.
Old ones are approx 1 mm shorter than new ones.

Currently off road due to broken valve spring yesterday! Must be something going around, possibly mechanical COVID!?

Is this outbreak of Kiwi breakdowns some form of divine retribution for your successful handling of CV-19?? Sorry to hear your stories - hope you are all back on the road soon.

I have just done Phil's Centa mod on a service exchange basis, i know this is old hat to many of you but i enjoy the posts about stuff being done to the cars so thought i would post a few pictures.
The main reason for doing it, apart from the well known benefits, was to try to get to the bottom of a rattling sound i was getting from the Centa area
which i think it has done.

The kit comes with everything done and just needs fitting, the splines on the hub will fit perfectly to an unworn crank without filing, Phil can supply undersize spline that will need fitting if your crank is worn.

Tightening the crank nut F.T.

The Centa with the new support bearing and full size crank nut.

[Linked Image]

New bolts supplied by Phil that replace the poor originals.

[Linked Image]

I also replaced the clutch support bearing as it felt gritty and was noisy when spun and all the grease had come out through the metal seal.
Phil supplied a replacement with a rubber seal.

Pressing the shaft into the new bearing using the cheapest press on Ebay but it did the job no problem.

This is link to a video of the original Hub fit on the crank or lack of!

The new hub is a perfect fit and now at idle the rattle is gone, i haven't been able to go for a test drive yet as the car is SORN at the moment but am sure the rattle i was getting at 3K plus will be as well.

Doing all this makes me appreciate the work Phil has done developing the kit as its a lot of work getting the engine in and out but the number of times he's done it he's probably got it sussed now!

Thanks for all the photos and info Obie. Impressed that you did it all on an exchange basis yourself, I know some others have but it's quite a job. Looking at the clunky fit of the hub to the crank before, it should all run much quieter and smoother, certainly a job worth doing. I found a lot of the vibrations and clunks went after doing these Centa mods, not all of them but a lot laugh2

I know Phil says it's not needed but I drilled and wire locked the four Allen head bolts that hold the insert retaining plate in place. You don't want them falling out but as they occasionally need to come out you don't want to do them up too tight, use locking washers or Loctite, they need to be positively locked I think. Maybe overkill on my part?

I know everything else is Loctited to stop it coming undone on the engine but i did as Phil suggests and left them as is. They would be a pain to remove with the limited access if Loctited winding them out so maybe locking washers as you suggest?

I drilled and wire locked them, that way they will be easier to remove when the time comes but positively locked.
