Mechanical lifters on my wishlist!

[Jeffer]

I still have mechanical lifters standing on my wishlist. Now iI saw a set of mechanical buckets from catcams, but I would like to know if someone from the forum uses these?
Are they any good, and can I go up to 8000 RPM with those? I was only planning to replace the hydro's no other cams or valves.

Thanks,

Jeffry

i got a ften who rews 8500 with hydralic lifters. but he is using harder valvesprings.

You can use the bucket tappets from early 5 cyl engines in the 20V head, but they are expensive and will need shims, this would take ages to do aswell. Also what clearance would you set the tappets too????

I think we are going to use either catams or make our own buckets.
No Idea 'bout clearance yet. For now I'm using hydro's but ina couple of months I change to solid lifters

What needs to be done to the cylinder head to run solid lifters ?

You need to grind your cams to mech profile,and you can buy lifters from here

I know, Geir Roesten sells them ... So the cylinder head doesn't need any modding to use soilds.

Nope,not with the type of lifters he sell.
Great stuff

Thats great news how often should the clearances be checked.

Depends on the spring rate,what kind of valves,egt and so on,around 20K road miles should be normal "acceptable" intervals.

[caterpillar]

you may use old mec lifterunits from older than 85 and from older diesels.... they fit right in, and if you use the thinnest shim (2,2mm) you does have to cut the valves in the upper end.

[aelred]

you may want to check the compressed spring height after the cam has been reprofiled
