how to recondition an engine!

Post by **dave friday** » 12 Aug 2007, 22:43

Well more advice really, i've found a machine shop so...for those of you that have done your dismantling and assembly a few questions.
is the crankshaft timing gear/sprocket? bolt a stretch one? how important is the thread lock type?.are all bolts that are tightened with a final 90/120 etc deg stretch ones?.
again any advice more than welcome.
thanks Dave sunday.

There is a modified/upgraded cranckshaft sprocket bolt, which is a stretch type. You can tell the differenec as the new one has a small "pip" on the head-end of it in the middle (it`s also 12 sided) Make damn sure it`s tightened properly/tight enough, and I would use Loctite on it as well. They were modded due to the earlier types coming loose, the sprocket wears out its loctation notch, the timing belt jumps and then the engine gets wrecked (local VW dealer said it used to be common on the early TD engines (Golf, Passat etc)

Westy, the bolt on mine has k a m a x on it.I've tried to undo it[van in gear hand brake on chocked wheel]so far no go,is it better to jam the crankshaft with a bit of wood?.

Would it not be best to make up a tool that engages the crank shaft sprocket as to lock it up.I have had problems like this my self an extra bit of time making up or obtaining a tool makes the job less stressfull.

Camper,i might take the whole engine to the machine shop ,perhaps they have the tool to do it,also to get an estimate for the work needed+all the odds and sods.

An air impact gun will undo it, flywheel can be locked with some sort of device in the teeth if you have to resort to that, but the buzz-gun will undo that bolt.
