TAMD22

[Lloyd antares 620]

Hi I have a Antares 620 fast fisher with the Volvo penta TAMD22 p-b 105hp basically boat was running fine in march this year reaching 4600rpm 22 knots but timing belt snapped on myself shattering the cam . & damaging 3 valves & 3 buckets had the head tested & re skimmed x3 new cam buckets & x3 valves fitted with all new seals & bottom end was fine all bores & rings were ok so cracked on but wen I stated the rebuild I noticed they had fitted the cam on back to front so I had to obviously re take the cover off & turn it around as the locking hole wasn’t there I was Evan doubting if they sent me the wrong cam but turned around was ok & locked into place with my 6mm drifts .. all the rocker cover went back together re sealed & torqued to spec in correct pattern 22nm .. replaced my fuel lines as they were cracking in places so all new from tank backwards.. bled system to Delphi .. then main filter .. injection pump & Evan cracked injectors .. she revs full in neutral but was only 2200 under load so I immediately thought turbo as was looking its age & was the original garrett so new turbo / elbow fitted today & instantly sounded better more boost noises & now reaching 3200 under load so I know it’s not turbo as a brand new one was fitted today so my next call is either as I explained above maybe the inlet vales are set as the exhaust tolerances & exhaust as inlet but I don’t have the cam locking tool as the cover is what holds the cam down .. or maybe injectors / fuel leak & the front of the heat exchanger is leaking water but minimal amount as I did rebuild the heat exchanger wen the head was being done .. with all new seals from parts4engines it now starts better than it ever has not Evan 2 revolutions and she’s firing into life doesn’t sound tappy but now with new turbo & elbow it’s not reaching 4600 now only 3200 any suggestions welcome thanks in advanceView attachment 177155

Are you sure you've timed it right. There are two sets of timing marks on the pump pulley for turbo and non-turbo. Other thoughts are air leak from aftercooler, losing boost pressure or exhaust partially blocked.

Correct Camshaft?

Correct Camshaft?

Fair point. The camshaft for the MD22 is different to the TAMD22.

Thanks for reply guys greatly appreciated & yes only now after looking at the replies & previous posts I know the cams are different in the md22 / tamd22 pb heads I did purchased a perking cam from Poland for a really good price but I did look up the part codes and they matched identical so I’m confused to what action to take next like I said it’s starts & runs really nice pumps water amazing now I rebuilt the heat exchanger just not achieving full rpms under load definitely this cam needs investigation thanks

Yes I didn’t know they were different cams untill reading your reply but I matched the part code off the cam that broke so surely there the same spec as both numbers are identical so im
Confused as was running fine reaching 4600 rpm before belt went I have included some photos to show the one I ordered to the one that shattered & there part numbers are identical or did Volvo make the height difference on them cams as the Volvo part number is 3581133 not L141DF0A thanks again

Ha e you timed the pump to A or B mark?

Hi bobc I believe I had the pump 180 degrees out fist attempt so wouldn’t start so then had to lock all with drifts again take belt back off & rotated pump pulley 180• & she fired first time & ran lovely .. aww ok .. The A / B marks that your describing maybe i could have it set to the wrong one as TAMD22pb is the turbo version & the other mark is for MD22 so could be pump set wrong .. L141DF0A Perkins cam was already in my head & working fine so I’m unsure if it’s the cam that’s wrong as surly it wouldn’t reach 3200rpm with the wrong cam shaft & part numbers wouldn’t be the same thanks for your reply bobc I really appreciate it

That’s what it’s timed on now so not sure if correct or not

Your pump ahould be set at B aligned with the dot, with the engine at TDC.

The number beginning 358 is a Volvo Penta number and probably the camshaft in a box and and may be same as number beginning LD but you need to check a proper source
Changing the label and packaging can be dangerous and due to supplier trying to protect sales

Hi Scottie that Volvo part number starting 358 I.e camshaft is no longer in circulation or being produced by Volvo & the cam that broke / shattered on me was the exact same cam I was already running & was working fine & exactly same part number as the new one I purchased .. ….L141DF0A ….& they look identical so I highly doubt it’s the wrong camshaft as it wouldn’t be running as smooth as it is now surely?? It’s just not getting full revs under load iv done new turbo & and elbow also .. I think its pump wrong or fuel / injector problem I am going to take
Cover off next few days & check the cam lobes height compared to my old cam that came out & go from there if anyone else had had similar problems please Comment all input appreciated thanks Lloyd

 

[Lloyd antares 620]

Hi bobc I have a photo of how I got the pump set but not letting me upload the photo can I send them
Another way & can you see if it’s correct please thanks your reply is greatly appreciated thanks bob

I think the cam is a red herring, different lifts and the shims would be way out. Check the turbo boost pressure to make sure that the waste gate isnt leaking BUT normally not getting full chat is usually lack of fuel, either pump rack not fully open or other. As others have said, check the timimg as well, make sure its on the TMD mark, also you could check to see if the the timing dowel hole on the broken cam is in the same position on the new cam. I am on my boat in Portugal (md22) I bought a Maestro turbo engine a few years back and rebuilt it for a PBO article. Its sitting in my garage at home. Ive got the injectors and pipes here, they are different from the MD22 with different nuts on the injector end and are the dual injection ones. I thought they might fit my MD22, they dont. If you could use them, some beer tokens would need to come my way! Easy jet want £59 for a hold bag! The cam might also be for sale!

Beneteau381 thanks for your reply but my head is absolutely fried regarding this the new cam situation as I explained it’s the exact same as the one that snapped - L141DF0A - as the Volvo ones - 3581133 - are no longer being manufactured so if they came with the 3581133 cams
Standard then it’s been switched at some point to this perkings 500
with the codes L141DF0A I did try every Volvo penta dealer in the uk Evan trying France eu ect .. but could only find x2 in existence with the matching numbers - L141DF0A - & they were being listed as Perkins 500 series witch does match up with the one that shattered / removed so with regards to your cam that might be for sale how quick can you check the part code to see if it’s a Volvo part & as for injectors mine were all working fine before the belt snapped & I had them cleaned professionally so I doubt there the problem either I’m just 30+ hours in on this rebuild a good £££ in & still not 100% thanks for all your input I am going to lock the cam in place tomorrow & check the injection pump to see if that’s set at point B thanks to bobc input thanks again and will attach pics of the pump pulley & turbo / elbow both new thanks
