most are out... the others have penatrean and im waiting for that to soak right in, im spinning them and pushing them up and down to help it get right down.

some come easy... some didn't... the modified screw driver works a treat though.

any hints on the timing gear?

If this does not work cut a poly pipe in half along the length. Remove the cam and put the poly pipe in to catch the lifters. Then just push them down and out.

this was on a ford forum.... concerning hard to remove (mushroomed at the bottom) lifters

would this work for Holden motors? their reasoning is that if you force them to come up you will score your lifter bores.

Its the large roundy geary thing on the end of the bumpy stick.


Seriously, take it to a garage or engineering place to press it off and press the new one bacl on again.

Yes, your supposed to change both,timing gears come in pairs.

I forget for sure, but I think the small gear has two tapped holes to put a puller in, or you need a bearing puller to get it off.

I just changed the large one and put up with a bit of noise.

my timing gear is one of the old cotton fiber ones that mr wippy warned me about....

reason i know.... with the slightest of pressure it snapped. the small gear is metal.


am i ok to get a second hand one or is it one of those "you have to replace them both together" deals?

and are the 202 and 186 timing gears the same? as i have a 186 sitting their i could harvest it from.

I don't think  it would cause any issues if you use only the cam  gear off your 186, as long as it is the aluminium type. You will need a hydraulic press to change it. most workshops would have one that a carton of piss would get  use of.

hey able, did you get the job done? i only just found the thread..

A few things that would be handy to know..
If you plan to make the motor rev, you're best off getting lifters that are anti-jack to 7000rpm, the others wont rev past 5800 (in the race cars anyway)

The straight cut timing gears are much easier to get lined up (J.P make good ones)

as was said you want to get oil into the lifters before putting them in, the method said above was good, we usually just use an oil can tho.

we've never bent a screw driver, but that was a good idea. We usually just use a flat blade in thru the side plate.

that should be enough for a basic motor, if you need to build any sort of performance motor, i have much more wisdom available....

good luck

just got my timing gears last Friday morning... i have had zero cash flow for a few months.

now all i need is my engine crane back from the friend i lent it to so i can pull the front end out.
i was reading a few forums and people advise against straight cut gears as they tend to eat each other and leave glitter in the oil. they do sound great but a few people also say you get sick of the noise after a while. one or two people even went as far as calling them wanker gears :o

the normal gears they say are stronger as they have four groves contacting at any one time spreading the load across a larger area as opposed to one tooth and grove with the straight cuts... this made both economic and reliability sense to me so i just went the normal one's (aluminum ofcourse) from jp performance. $63. well $70 after our government mafia got their tithing...   ;D
