Crane cams

[Malcolm Taylor]

Hello,

May I make a late contribution to the 'Crane Cam' exchange.

I fitted a Crane 340-0010 (ex Moss UK) to my stage 2 XPAG some 15,000 miles ago and can only say that I am delighted with the engine's behaviour, particularly since I rather belatedly fitted shortened push rods. Crane Market it as suitable for TC/TD/TF.

I do not understand cam technology sufficiently to compare the -0010 and -0002 models in use but I quote below the comparative details of the -0010 so that interested and knowledgeable members can compare with the -0002 specifications already quoted by Skip.

Valve settings: inlet .016, exhaust .018 (hot)

Lift: int.@cam 280, @valve 353; ex.@cam 294, @valve370. Rocker arm ratio 1.26

Cam timing @.016 tappet lift: in. opens 24BTDC and closes 56ABDC with advertised duration of 260

ex. opens 69BBDC and closes 21ATDC with advertised duration of 270

Cam timing @.050 tappet lift: in. opens 6BTDC and closes 36ABDC,max lift 105ATDC, duration 222

ex. opens 51BTDC and closes 1ATDC,max lift 115BTDC, duration 232

Recommended rev range: Minimum 1800, maximum 5200.

Further to my last message, my cams are AAA3096 or Crane 340- 0002. Skip's figures are correct and like Mike Card said there was a typo on my part. Although I got them from B&G, they were in Crane cartons with all crane information and I previously spoke to Crane on the phone who confirmed that they supplied these to B&G and others. They suggested 2 sets of valve clearances. 16 and 18 or 18 and 20. I've been running happily on 16 and 18 but the valve gear continues to speak to me in typical XPAG fashion. I would guess that Skip's 18 will be a good compromise. All the Crane data stress that their cam should only be installed with new followers. Viv

Hi all, Am looking to buy a NOS Crane cam for the XPAG Serial No. BF1831 grind 972041 I think. Anyone know what state of tune it is? Standard, half race? Regards, Ron Benson. PS Richard III still owns N Yorkshire, [Non-text portions of this message have been removed]

Greetings et al, The reason I was asking about the cam was because I was bidding for it on E Bay, I asked the question about which one it was to the seller, but received no reply. Suffice to say I was outbid! It appeared to be very old stock and thats why the numbers did not tally. I am at present running the AEG122 cam in the TB which according to Mike Sherrell is almost the same as standard TC. Many thanks for your replies.

Dear Group A word of caution if you are going to fit a new Crane Camshaft into an XPAG. When I completely rebuilt my engine 8617 the camshaft I took out was completely worn out. Replacement was the only option and I settled for a Crane Cam as the steel used in the cams would be guaranteed quality. Fitting the cam was no problem the original thrust plate was tightened down (I assume original because of the ring tone it makes when dropped, good steel) and the engine turned over by hand for timing purposes. (No details published of any end float between the thrust plate and the nose of the cam?) At a later stage started the engine and ended up with a very noisy tapping sound. The end float between the cam and the thrust plate was not enough and the cam had subsequently grabbed causing both securing bolts to shear off allowing the cam to move forwards and backwards. Engine strip down new thrust plate fitted cam shoulder machined slightly to increase end float. Regards Dave T Down Under TC 7732

Years agoI had fitted a new repro cam gear to an engine and it turned out that the part numbers cast into it on the backside were higher than original and were inline with the upper thrust plate bolt bolt and the noise was not there when turned by hand. What a racket and the noise was immediate and very rhythmic JOE CURTO INC _www.joecurto.com_ (http://www.joecurto.com/) joecurto@aol.com (718) 762 - 7878 -9-5 EST 22-09 126th Street College Point, NY 11356 In a message dated 1/8/2010 6:26:26 P.M.

Howdy, Moss Motors is featuring a Crane cam and a lifter set in their photo section of the catalog update. It sounds good - marketing BS? - but does anyone have a feel for if these products are indeed good? I installed a Crane setup 25 years ago and it was fine, but it sounds like Crane is in transformation.... Where do you guys (and gals) get good valvetrain components for the XPAG? Cheers, Bill
